Cable tech here, most people have no idea how wifi works
Regular Joe who does tech for a hobby, 100% agree.
Former cable tech, I still don't know how wifi works
While true, that actually makes their advertising clams even more egregious.
That goes for anything, iam sure you are on a lot of lists when people say most people don't know how (blank) works.
Internet cable tech
There's also one additional thing: the advertised speed is RAW speed. Including all the overhead of Metadata to transmit all the packages.
Give it to me raw and wriggling.
Imagine all the package headers, checksums, and lost bytes!
LTT labs need to test wifi devices in Room sheilded from all possible interference to see if in perfect environment the advertised is acheived. Even in perfect environments I am willing to bet it will never be acheived.
In one of the lab-tour vid Linus already said that such test are on their list for the near-ish future 😎
this theoretical max speed also includes packets overhead. My old-ish "300Mbit" router can push less than 200Mbit to single device over Wi-Fi, yet Windows reports 250Mbit link speed. It's my only 2.4 GHz router and I live in rural area, so this boy has a perfect environment to stretch his legs, tja
Yeah, but not in an anechoic chamber. Because that will make multiple spacial streams impossible, if I understand correctly
@@Suchtzocker This channel is owned by the same people, i believe
I am willing to bet your 100% correct even if you have two identical routers with same 4x4 streams in middle of nowhere you won't get those speeds, manufacturers claim those are lab controlled results, something tells me you will get those results where air doesn't exists those are their optimal conditions where you will be watching CZcams and can't even breathe 😂
Also, they usually show a max throughput inside the router and not per channel. So the router can claim a 800Mb, but the max per channel is 400Mb, and if one channel is using 400Mb, a second can have only 200MBb and a third and a fourth 100Mb each, and so on
Even worse the design may be bottlenecked somewhere else on the PCB so the max throughput of the chip is never going to be reachable.
But the brand still put the number directly from the vendor on the box without ever running an in-house test to confirm.
Wi-Fi traffic has to be encrypted (separate from the HTTPS security). That eats up a big chunk of the data being transmitted.
@@RBzee112 Also that. You lost a chunk of data due to protocol. But that will not be accounted in the system monitor's consumption, just in the download rate.
You got it 💁♂
Oh yes I remember when 5 GHz was new in consumer projects I worked in an electronics store. Constantly had to explain the differences and how their devices needed support and such
At this point those ROG routers seem to be made with the flashy ROG design in mind first and the speeds etc are an afterthought.
I mean no. It's not like the router manufacturer is hiding the speed setting from consumers. Any modern router you get will be using the latest technology possible.
The point is that real world performance and how physics works limits the theoretical maximum performance that marketing claims.
it's like buying those 4GB usb 2.0 just because they have a ""cool"" shape.
@@PacMonster0 yep marketing is the real "villain" in the world
Slow wifi is one of the most mildly infuriating things to deal with
Cries in German 🇩🇪😢
I've never had faster than 10mbps, which is usually 6mbps in rural indiana. About to get 50mbps, should be game changing lol
@@sategllib2191 We got wireless to my parents like 13 years ago and we lived in the Finnish countryside, I was finally able to play online games but downloading 200MB took like 2hrs, oh those were the times.
Bro i cant fucking stand it. I ALWAYS have issues with it.
@@sategllib2191 OOF my wifi on my phone is only about 300-500mbps (my ethernet is double).
Is LTT Labs gonna test routers to see which are closest to specs on the box under real world conditions?
LTT and real world conditions kinda contradicts 😅
** for certain definitions of "real world" 😀
but this would still be useful b/c it can provide insights into your "real world" needs 😁
None lol….
No. This video talks about bad marketing. But upon closer inspection anyone can determine the access points certified WIFI5/WIFI6/WIFI6E and it’s spatial streams as it’s limits, lastly your devices at home have similar specs, resulting in the lesser specs as your overall limit per device.
How is that posted certification any more reliable than anything else on the box? People can print essentially whatever they want and there isn't really anyone holding them accountable.
A noteworthy addition is that unlike older wifi generations, wifi 7 will support MLO (Multi Link Opperation). This will allow host and cliënt to transfer data over multiple bands at the same time. So in this case the speed is not limited to the max speed of a single band anymore. It's pretty nifty and would also make switching between bands way easier to the point you wouldn't even notice it (except for a change in speed maybe).
They already made a video on WiFi 7 so I'm sure they know. That's also likely why he says WiFi 6 specifically doesn't support this
Isnt multi link similar to wifi 6 ofdm mode?
There's going to be others who would just have wifi 6. So they aren't going to upgrade to that that soon. Or at least until wifi 8 or wifi 9.
It’s nice but it will take years before all hardware you use supports it. Esp. if your internet provider says you MUST use this modem with built-in wifi and it still uses an older wifi standard or it implements wifi 7 in such a way that it’s slower than wifi 6 or even 5.
@@maemilev No, OFDM/OFDMA is a technique that crams more packets in a datastream, it allows for less unused space on a specific frequency because it optimizes the throughput. MLO actually combines multiple frequency bands into one datastream. The two are used together to create the high throughput.
2:09 Maaaaaan, that transition was smooooooooth 😆

And remember that you will never ever get higher speed than what you pay your ISP for. Just cause your router says 1GB/s doesn't mean that your 100mbit/s will magically be upgraded. From working in tech support for an ISP this is by far the biggest misconception about WiFi and speed
Internal network speeds can be as fast as you like, and _should_ be as fast as possible, regardless of internet speeds. I wish people understood this... There's a lot more going on on your network than just accessing the internet, and the faster everything not leaving the house can get packets to and from the router, the sooner anything outbound or inbound can get routed.
@@NoobixCube Yes absolutely but I feel like that isn't what most non LTT enjoyers think about when talking about WiFi speeds. Much less utilizes that internal speed in a meaningful manner.
It’s still worth having faster LAN networking.
I’d love to have 10Gbit throughout my LAN, even though my ISP only supports up to 2.5Gbps.
So in North America WiFi and Internet are synonyms? My ISP has nothing to do with my WiFi speeds, why should it?
@@Alvin853 Just loose use of jargon. Wifi doesn't exactly mean internet, but functionally, if you're using wifi, it's almost always to access the internet. Thus, whatever speed you get on a ping test will be indicative of either wifi or internet speeds, whichever is slower (generally speaking).
It was kind of glossed over (or not mentioned), but often that speed is how fast all devices could possibly be. 15Gbps doesn't mean one device can go that fast, because (as far as I know) there are no consumer WiFi standards that fast. It just means you can have 15 devices all at 1Gbps (or any combination that adds up to 15 Gbps).
Worse is when they do this with Ethernet add up all the max speeds of the Ethernet ports and claim that as the speed, even though no one port would be capable of that speed.
It's a combination of all that was said in the video. Your typical device does not have support for 4x4 MIMO and can't work at 5 and 2.4 GHz simultaneously, therefore it won't reach anywhere near what's advertised on the box.
I thought they stopped doing that with network switches. Like there's a couple of kinds of ways of measuring throughput but they're pretty explicit in what those numbers mean. It gets really weird when you start getting to high speeds and breakouts and such.
I don't know though, I don't deal with consumer goods.
@@NotHugs While the theoretical speed is relevant, its never what they put on the box. They always put the combined maximum link rate of all radios combined, which is entirely irrelevant as usually the routers CPU isn't even fast enough to push that much data anyway.
My favorite is when they advertise "5gbps" or something and there's only one uplink port and it's 1Gbe
@@TjPhysicist LAN data transfers do exist
Netgear be like: ZOMG, 2345Mbps.
Also netgear: Here, have a 100Mbps WAN port.
The power thing is not just a legal matter. If you double the power of the signal (that is +3db), the area you will cause interference in (so where another networks cannot use the same channel) will increase a lot more than just double. So if every network did that, in a populated area, everyone's network will only get worse.
Fun lesson in jamming wifi
I would think in about 99.9% of cases it's the speed from your isp that is THE factor in what you see on a speed test. At least in the US, where internet speeds suck unless you're willing to pay over $100/mo for it.
The good thing about that is that a lot of mainstream routers come with software that show you the speed from the modem to the router. It saves a lot of headaches of calling 1800 number
99.99%
Wait, the biggest question I have about this video is..
what the hell is the Hawaii chair?
Not a peep about it being the signaling speed rather than the throughput speed?
I mean... okay. We'll just pretend that there is no overhead with TCP/IP.
"we also have to say a quick word"
*Swipes down*
"about channel width"

Ethernet master race rise up!!
A big limiter I just learned about is many routers LAN ports are only rated for a fraction of their "rated" wireless speed. I learned that I had only been getting less than half of the speed I had been paying for because my router, which was rated for 800Mbps had a LAN (connection between modem and router) that was only rated for a measly 150Mbps. This effectively cost me hundreds or thousands of dollars over the years. Pay attention to all the specs kiddos! Or even better just go build your own router. LTT has a great video on that
building your own router doesn't make sense for regular network speeds. It would be feasible if your network is 2.5Gbit or more. Even off-the-shelf 2.5Gbit routers are becoming more and more affordable. Level1Tech have good videos about DYI routers
I have 5GHz wireless router with advertised wireless speed 1.2Gbit, but LAN is just 1Gb, so marketing is bs. Is your 150Mbps LAN an internal connection (i.e. between modem and router inside one device)? I'm curious since 150Mb isn't standard speed for wired connections
Sounds like you have other issues there my friend. If you have a gigabit ethernet port, that switch in your router is capable of pushing that speed. 150 megabit or 150 megabytes per second? There's a whole lot of difference.
Wi-Fi traffic also has to be encrypted with WPA2/3 (separate from the HTTPS security). That eats up a big chunk of the data being transmitted.
You forgot the most important thing : the number indicated by the manufacturer is the PHY rate not the Data rate as you mention in the video and as the manufacturers want you to think
The PHYrate corresponds to the whole link between your router and your devices including the headers and the preamble, If you need to send 20kb of data over wifi, you will need to send at least 15kb of additional header and preamble.
The PHY rate is globally 2x more important than the data rate, If you have a PHY rate of 2400mbps (the PHY rate of a 2x2 wifi6 @160mhz) you can go up theoricaly to approximately 1200mbps with perfect condition as you mentioned.
Bigest scam about routers is the fact that some routers like tp-link c50 decleare that they can achive 867 Mbps at 5ghz while their wan port is an ethernet port of 100Mbps.
lol yeah
Well it can still be capable of transmitting data at that speed. Internet downloads isn’t the only thing that can be transferred. Home storage is a thing
Well, it could transfer 5ghz data at that speed locally, say to another device connected to your wifi
but yeah that's a very limited use case
No not a scam on the spec sheet from there site

@@darthsungam dont tell me people buy router for home storage. What a stupid argument
"technically correct, the most misleading kind of correct" - most marketing dept
3:06 I have recently bought this exact router model and found one interesting point causing lower speeds - if you switch on ceiling fan, the fast movements of the blades kill wifi signals in the air causing higher speeds to decrease by 60-70℅ which is a huge impact.
I have not seen anyone talking about this topic except very few websites.
If you have high speed internet like 1 Gbps+ and getting lower speeds, do check this point.
When I did customer facing tech support for the ISP I work for I used to explain router speed ratings (e.g. AC1750 or AX2100) as "the theoretical maximum amount of data your router can push around wirelessly at any given time, on all bands combined." Customers would get upset until I reminded them their internet connection was only 200/200
In my opinion the ISPs are 1000% more shady and awful than the misleading advertised speeds on routers.
Edition of this video is smooth!! Great work!
I love adding speeds on routers. I do the same with cars. Most people drive 60 on the highway, but I'm flying at 240 since I add the speed of all four wheels.
Should be a truck driver, get 18 wheels, you can be doing 1080 without a snowboard.
I am also slower than advertised.
I'm much quicker than advertised
By TP-Link's logic, I am thrilled to discover that my 2 family Toyotas have a top speed of over 300kmph/186mph
I am not sure if this was covered before, but talking about the difference between Signal Boosting and using Access Points to widen the range of Wifi and also how easy it can be without investing into the most expensive of gadgets. I am sure it depends on speed, we only had to widen a 200Mbps network which we did via two Tp link mesh routers in AP mode and switched off Wifi on the main router to avoid connection issues. Also when switching out the main router later on, we realized that we had to start the setup of the entire network to make it work as intended. As in disconnecting the AP points and start out with only the router. Now all is happy and we have reliable good connection everywhere.
I personally hate those mash thingys. Well they are great in covering a wider network without running cables, they slower your total throughput. So if your ap1 and ap2 are meshed and ap1 is the one with the cable to the router, you are sending everything through ap2 and ap1. Thus leads to splitting possible bandwith on ap1, lowering the maximum speed n ap2.
@@Klausmd5 It's not "mesh". Exactly why I brought it up. Both APs are connected to the router separately. As far as I understand a mesh network is where You have the Main unit and a Slave units connecting through that. In our case the two APs have actual seperate dedicated connection to the router. We had two network connections only coming out of the wall in the entire house. Speed was terrible with a central Wifi unit cause lot of walls and blind spots. We then placed two APs right at those network connectors (two opposite sides of the house) and the only thing that we had to hook up with wire was the PC, which was occupying one of thr network connector. I could just connect that to the AP there directly. So there is no loss in bandwith. Great Wifi coverage everywhere. That's why I think it would be important that people know what the difference is. You don't need direct wire to Your gadgets just some strategically placed wires for Your APs.
One more thing to know, it states the link speed, the raw speed between your device and the router/access point, just like how a product gets packaged, your data is packaged multiple times, making the actual usable data speed slower
I learned this quite late but.
If it says 100Mb with a small b they mean bits.
If it says 100MB with a big B it mean Bytes.
This means if you see the small b on a speed advertised you have to devide it by 8 to get the actual speed you are getting.
Just curious, but didn't you learn this back in school??
I studied in India, and understanding the differences between B and b was one of our first lessons in Computer Science (as the subject was called) from back in 2004/05 when I was in 4th grade.
Please don't take it as me being condescending. I'm just curious if this is common school knowledge in other countries as well.
Also your comment is right. ISP's generally advertise bandwidth speeds in Mb's. So a 100Mbps connection would theoretically give you around 12.5 MB per second in download and upload speeds if your ISP provides asynchronous connections.
Otherwise you'll only get the 100Mbps/12.5MBps for downloads.
@@arvindrueben a lot of us was barely taught touch typing (RSA I think it were called), and had to learn all that other computery stuff ourselves. Your tutor was probably from our era too.
This video feels like it's 10 years late. They've done this for a long time.
You should go into further depth about the channels, and their bandwidths. E.g. why it's so important for people to choose Channel 1, 6, and 11 (in the US), and how if anyone else set's their channels otherwise, are subject to interference conforming to the channels, and being a source of interference for the neighbors. "It takes a village" as they say, and if we can all adhere to sticking to those channels on 2.4ghz the better we would be.
Funnily enough right when you said interference, the video started to buffer while I am connected via WiFi ... at first I even thought it was part of the video 😄
Ah WiFi and Internet are terms used interchangeably, in the minds of some they are indeed the same thing.
One other thing to note is that if you have one very slow device connected to your router (actually Access Point, even if it is in the same box as your router) it can drag everyone else's speed down on that channel.
I've heard from a repair guy working for a big network company that there was 1 case where the smart fridge was interfering with the router. Every time the motor for the condesation cycle would start they'd lose the wifi in the house.
I also like how people conflate "wifi" with "the internet". "The wifis down". No Mary , your internet's down and the radios and signal are indeed fine.
Thank you I was going to get a WiFi 6e router and I only had my current RAX42 router a a little over a year. I will wait for 7.
Kudos for the transition to Riley. That was surprisingly clean
I have to add that some devices, like the HP Pavilion gaming laptop I had, have a pre-built bandwidth cap on the wireless module (25mb/s up or down in my case), and the only way to receive faster bandwidth is to either plug in a USB Wi-Fi dongle or connect to the router through an Ethernet cable.
Beyond all stated in this video. Wifi is still a half duplex network. The more devices talking in a CMSA network the more delay you'll have.
Wait wait wait... did they just forget the ONLY real reason? Guys you need to pay for your internet. Even if your router can handle 1000gbs you still need a internet connection that fast.Yes numbers on product boxes are always theoretical but the reason is still the connection wired to the router and not the router itself....
But the video is about the speed of your wifi, provided exclusively by the router, which technically has nothing to do with the isp speed.
One big issue with the wifi speed being misrepresented is when you might be moving data locally within your home network, say from one pc to another. It's going to take way longer than the advertised speeds of the router would have you believe.
They are talking about LAN speeds here. It has nothing to do with the Internet Speed (WAN).
Cover the actual wifi settings next. The popolar ones we know about but there are so many other ambiguous settings, some of which seem useful but are off by default
if your microwave is interfering with your wifi - you might want to get a new microwave because it's not safe.
Also also also, company shenanigans where they say "Offer: 1gbit per second connection" then when you tell them your address they tell you "Actually our good and mid cables don't go that far so you'll be getting our weak line" and then you still get less then what they estimated.
My "100mb/s" is almost always 60.
Not even the router fault.
Thanks for the video!
Feeling miffed that you called out my exact tp-link modem-router. Luckily, the internet is shit slow here in Australia, so it doesn't impact me. 😂
thank you..awesome info..
Yoo that sponsor transition was sick
The speed addition thing is always the scammiest thing I became aware of in the past.
It's the equivalent of a cop pulling you and the guy behind you over and arresting you for reckless driving because you were going twice the speed limit.
You know, since you were both driving the speed limit.
I work as an ISP in the returns department for routers, I've seen many people complain that they weren't recieving the max speed via wifi and our cs team just give them a new router to make the customer happy, even though chances re they still wont get the max speed
That's why everything should be overkill as much as possible. As 10G Internet, LAN and WiFi7! NICE!
The advertised speeds are for local transfers over the WLAN. They just use those numbers because people tend to lean towards thinking the highest number is the best without much context. People tend to forget that WiFi protocols still work without access to a WAN such as the internet. It doesn't help when most people conflate the internet speed with WiFi speeds and companies have taken advantage of this.
You've missed the biggest factor in the discrepancy. The quoted speed is the actual link speed, but the protocol can't use the channel 100% of the time. Devices have to frequently stop and allow other devices to transmit, thus reducing utilization. If the SNR is high enough, individual 802.11 packets can be transferred at the advertised speed. Multicast packets are also sent at a lower bitrate that can tie up the channel for a significant fraction of the time.
The speeds that routers mention is not the speed a device would get, but the capacity Max data rates across 2.4 and 5 GHz combined that the router can handle. So if you had 10 wifi 6 devices across both bands trying to do heavy download/upload (assuming your internet provides unlimited speed) the Max data throughput combined on the router will be close to the advertised number (assuming great channel conditions)
This information is good for beginners. Well Done.
whenever im playing siege with my friends ill hear a "MOM TURN OFF THE MICROWAVE!!!" cause it interferes with the wifi he has
Honestly, my home connection is 600mbps and the WiFi on my work laptop gets to 500 (and a perfect 600 over Ethernet).That's more than fine by me.
3:10 Not just that TP-LINK one. Almost every single router on the market does that. That's why you need to check the specifications and see what's the actual bandwidth for each frequency on the box...
it never false advertised. it said "UPTO" so anything that says upto 6 gbps transfer speed, if you get 5kbps, it's still within that transfer speed claim.
Honestly, my Internet speed is not fast enough to max out the WiFi speed anyways so I won't notice it, ever. XD
me too
The fact is that you always have attenuation with any existing signal there is, even with a direct LAN cable you have some attenuation
Maybe i missed it, but you guys didnt mention multi-pathing. The signal can reach your device through multiple different paths in your room, each with a different latency. This also effectively acts like interference.
Me who’s internet sometimes gets 21MB/s when I normally get 18MB/s when it’s not randomly disconnecting for a few minutes every so often.
i bought Archer AX50 couple of years ago only due to the wifi 6 and the wifi6 speed at over 2400 Mbps because we have 1 Gbps internet connection and wanted to make sure if we get a 2 Gbps internet to be able to actually make a full use of it's speed lol
The radiation will also interfere with itself, or rather with it's reflections from walls, furniture, etc. And diffraction around corners has in influence, like additional reflections from this and changing wave conditions.
This is the reason I still use cables when connecting to my modem.
My internet is literally 0,000065% of what it was supposed to be
This pissed me off so much when I was shopping for a router. Their marketing is so opaque and misleading it's really hard for a consumer to make an informed choice.
Wow! This episode had 50% MORE! (compared to a three and a half minute episode.)
Routers are meant to serve more than one person usually. That is why you get less than advertised speed UNLESS you have a physical ethernet cable connection to the router. That said I have gotten 20MB/s speeds on 2 devices at the same time (Playstation 5 connected by ethernet and regular gaming PC via wireless) so even the Xfinity router I have is doing work.
A month ago I called my ISP because I was having speed issues. The first thing the customer service representative said to me was: “I see that there are WiFi coverage problems in your home, if you order a range extender or Mesh router from our online store, the problem can be solved”
I answered, how do you know my house layout and how can you check that over the phone? She replied, “I’m going to run more tests on your account” and then disconnected the call.
I wonder how many people get tricked like that.
Don’t use a mesh system, every node it hits cuts the speed in half. So if you get a three node system you’ll be chopping your speed by 77%…
If this is a real story, then try contacting some sort of scam advocacy group or complain to some overseeing government body so they can investigate what sounds like a blatant scam attempt.
They are like Boss amplifiers. 5000 WATTS MAX! When lighting strikes! 😂 it’s actually like 900 watts!
For the first time ever I get the speed promised in my contract via a wifi connection. Normally that speed can only be accomplished via cable. But as we are talking about just 100mbits it's probably not that special, while still being quite rare in my country.
LTT should do a video where they attempt to achieve the listed speed on the box of the WiFi router by eliminating or reducing as many of these barriers as possible.
Ooh pretty RS3 during the Attenuation talk!
3:10 hah, i have similar router with wifi6 (ax5400)
ever since i got it, never had any issues, (2 years so far)
it goes up to ~1200mbps on my PC which almost directly floor above.
not long ago updated my house to vodafone gigabit. the router stated it was gigabit compatible for wifi 6, turns out could only manage about 600mbps average with my PC using the mesh router to connected to router downstairs. and being right beside it on the phone couldn't even achieve 140mbps... thankfully ive managed to route a cat6 cable from upstairs to downstairs and into the router thx to a impact drill and about a 18m long cable. easily get 900mbps now
I work for an ISP and although I knew some of this in still sending this info to all my coworkers.
LOL, file this under "No shit, Sherlock," tell us something we don't know.
I have a question: a mesh network or multiple AP i better to cove my house with wi-fi? Or they are both the same thing?
I chucked some unifi APs around the place and havn't noticed a problem with speed.
The transition into the sponsor was nice
Aye, liked it.
I had to scroll down too far for this comment
I was obsoletely shocked when I got 600+ mbps on a Speed Test. Here in Australia, before I upgraded, I was lucky to get up to 20.
i thought another reason was that they put the throughput number on the box and not the bandwidth, in other words if you download a file that's exactly 1gb there's more than that in total traffic because the data has to be broken down into packages and stuff and you're not just downloading data but the structure of the packages etc..
Interesting so that's the reason a 1gb download will user more than 1gb, I guess this depends on your reception ( at least in my case) I use mobile hotspot 😅
But it would be interesting to test
The most common explanation to whatever question "why marketing?" is: because marketing is deception and gaslighting, not actual factual information.
You guys should contact the router manufacturers, ask them what their "ideal" conduits are, then recreate it, to see if it comes anywhere close to it.
🐢 Tech Turtle likes this.
Would have been nice to mention the fact that wireless runs in half duplex mode, unlike ethernet which mostly runs in full duplex mode. Half duplex means that the physical connection speed advertised (say 1.2Gbps) will only give you half the actual speed (600Mbps on an advertised 1.2Gbps connection).
also on lower end hardware the WiFi speed is limited to 100mbps by the Ethernet ports
James morphed in Riley. Would have blown my mind if I didnt already believe they were one person with interchangeable bodies.
Didn't watch the video yet but a couple years ago no one told me I had to upgrade from 3.0 to 3.1 to actually get those speeds advertised. Xfinity didn't really care because I was using my own router at the time. When I moved I switched to AT&t gig speed and I'm paying for 500 And I'm actually getting 500 plus. But overall cable seemed to be more reliable and by the way AT&t literally cut my cable the day they came in and did the install. So now if I want to switch back. It will be a little inconvenient to have a line run across my lawn for however long
The first half of the video is completely wrong, as I've never once seen them advertise the maximum speed in "optimal conditions", its the maximum link-rate of all radios added together (which you practically gloss over later). Which even if you managed to get those link rates, the CPU can't necessarily handle moving data at those speeds, seeing as WiFi is effectively software-switched.
Seriously, whoever is writing Techquickie gets things wrong every-single-time, its extremely frustrating!
One glaring omission. . .wifi is half duplex.
James has grown into being such a great presenter, he could branch out on his own and be very successful. Look out Linus!
Most services only allow a limited download speed...
usually around 15-25 MB/s 😅
I get better than advertised speeds. The bottleneck is the provider for 90% of us.
even though manufacturers are doing this to deceive people, us consumers should still realise the different between the "speed" and capacity of your router. the maximum speed I'll ever get wired straight to my home router is 1Gbps, that's the speed of the ethernet port I'm connected to, but its total capacity is closer to 5-6Gbps due to it needing to be able to support multiple devices doing traffic at their maximum port speed.
