I am into security and privacy and I love this video 23mins worth it! More videos similar to these and probably home automation or home servers please! Clear and well explained 😎
Thank you very much!
Very informative and in-depth review with crystal clear explanations. You earned a sub my guy!
Really well made and explained video. The quality is far beyond the average youtube channel and you really deserve more views/subscribers. Thanks.
Thank you very much ;-)
Wonderfully thorough and concise video on a budget/affordable solution, my favorite. I am really looking forward to that mesh video as I have already dipped my toe into OpenWRT when I bought the DIR-2640 earlier this year after your previous videos. Thank you for making this so much easier for the laymen like myself and exploring bank for buck territory.
Thanks for your feedback! Hope you are happy with the D-Link?
CZcams algorithm recommended your channel and really love the high quality content, got lots to learn. Thank you !
Hi, that's awesome! Welcome ;-)
Marc your channel is purely amazing. Your explanations are crystal clear even for neophytes like myself while managing not to sacrifice too much in depth technical detail.
Excellent video as usual. I am myself definitely reluctant to have my devices dependant on a cloud service, ad have been trying to get home assistant running at home.
Cheers!
Thank you very much:-)
i just second that, your explanations are excelent, i am learning a lot just watching your videos
What an incredible video. Thanks for your hard work
Without you I might've never known my router's performance could be that smooth and stable. Thank you very much!
Awesome - many thanks for the feedback !
I love your posts! Great presentation in even better English, my compliments! As the videos are often on the edge of what I can comprehend, I sometimes end up watching them more than once...
I always worry a bit about my privacy and security, so I try to stay away from using "cloud services" from various companies. I must admit that I'm not always successful though.
Looking forward to a video about the mesh implementation you mentioned at the end of this video! Greetings from Holland. PS DM1,50 lol.
Dank jij wel Jaap 😉
Quality, Concise, yet Comprehensive video. I'll give this all my likes if I could, liked and subscribed!
Awesome - thank you so much for liking, subscribing and for the feedback!
Your explanation is suberb… the highlighted details, awesome… 👌🏼 (lol watching this 2nd time, recommended video 😂, didn’t notice)
Glad you liked it ;-) Many thanks for the feedback !
Thanks I learned a lot from this video! It's packed with information, very useful.
Thank you Marc - many thanks for your feedback ;-)
Last year, before your video I asked the same question about all my IoT devices. Your videos explain a lot of how to overcome this issue on the home network. Thanks.
Thank you very much.
I just found your channel by accident. You have excellent presentation skills.This is what youtube is/was about... keep up the good work.
Hi, many thanks !
Love all your videos
Thank you for such a comprehensive and clear analysis and description of the device. As for your questions, I don't like my routers or firewalls open and accessible from the outside without something like Openvpn. I run openwrt or ddwrt on my wireless devices mostly as dumb access points and a pfsense box as my primary router with various vlans to isolate functions in my network. Great Channel!
Awesome- many thanks for the feedback!
Been waiting a long time:-), thanks for the video..
Thanks for waiting and watching ;-)
that is the video that I wanted, thanks sir, some cheap, useful and all in one vídeo, it's amazing 😍
Many thanks Luis, glad you like it!
This is fantastic stuff! Keep making this kind of content please!
Many thanks Michael !
thanks Marc, simple and good explanation as always👍
Thank you!
I like your presentation, and even more the way you think 😎I learnt lots. Keep going 👍
Hi Fernando - many thanks!
Thank you very much for sharing your experience and expertise on the home networking. I have been a system engineer for 10 years but i always felt away from the custom firmwares like openwrt. With your tutorial videos, a person can understand the logic behind the networking rather than just following your instructions. Thank you again
Thank you very much! I am happy if I can shed some light on networking- it’s fun if you get into it - but I felt exactly the same when I started ;-)
Also, I forgot to mention: Thank You! So much work and experience in this "review"! I want more!
I would also mention a gigabit switch, attach to this router with OpenWrt, and bam, you can connect your cameras, and more APs, PCs, what the heck you want. :)
Liked, subscribed, turned on the notifications!
Awesome many thanks!
22:05 And I agree with you Marc. I'll buy this one, maybe this week to do the same you did here. As always, thanks you for sharing this great insight.
Awesome- many thanks for the feedback- glad you liked it - let us know how it goes ;-)
Hello Marc. I have the hardware-wise similar Xiaomi Redmi AC2100 flashed with OpenWRT for a year now, having the same concerns with you. Nevertheless in my eyes a good choice for it's price, if flashed. I am impressed with your knowledge transfer capabilities, couldn't skip a second of your video. Keep up the good work! We will stay tuned :)
Awesome, many thanks Marios 😉
Thank you! Your videos are very clear and beautiful. With the help of your video, I easily converted my MI Router 4A Gigabit Edition into an OpenWRT device.
That's great to hear! thank you so much for the feedback. Glad it could help!
This video has a lot of useful information, many techs facts that Worth finding, it is a pleasant time to hearing that master class.
Hey Mario, many thanks for the gentle feedback !
Nice video! I was stuggling with an asus openwrt and high cpu usage and gonna test the hw offload tip you gave. Thanks!!
Great - let us know how it goes ;-)
I don't usually write comments, but I just wanted to tell you how great and educational your videos are, hope we see more DIY network ideas 💡.
Hi Soran, that's very kind of you - thank you very much!
Really interesting video..Thanks..
Hi Khalid, many thanks !
Hey Marc, thanks again for your videos man you are really helping in making everything easier to understand!
You mentioned the mesh network with xiaomi 4a router, can you please cover the 802.11s with openwrt?
That’s the plan ;-)
Great content, thank you once again!
You're more than welcome. Thanks for watching and for the feedback.
Great work!
Thank you very much.
looking forward for that next video, mesh!
It's in the queue - after VLANs for OpenWrt 21 and presumably NoMachine
Loved this detailed guide, especially for performance and technical aspects of this video. Hope you do more such videos. I have a TP-Link Archer C20. It's terrible. Just one CPU and connecting 4 - 5 devices increases latency like crazy. This router seems to have a decent cpu that can handle a lot more it seems
Hi Suraj, yes it has more juice than the Archer. However, Iam a bit reluctant to test equipment because vendors tend to issue new versions of the hardware and the tutorials simply stop to work or the characteristics change a lot.
@@OneMarcFifty True but even if OpenWRT is not possible due to version change, the router is still decent and cheap.. Maybe it will support openWRT.. I may buy this.
Really like your explanation 👍
Thank you Dhana!
Good done. T:-) ( Luci is in the release image when the device got enough space or power. Yes for this device for sure)
Thank you!
Hey, welcome back! Long time no see :)
Many thanks! And thanks for having waited so long ;-)
22:00 "At least to the vast majority of you"
Hahahaha incredible, literally rolling on the floor laughing!
Maybe he was a doner 😉
I will look forward to the video referring to this router's mesh network, I am grateful for your videos, Thank you!
Hi Emerson, many thanks for the feedback. I have just published it today ;-)
I was in the network security field; worked for an outfit many years ago. I've always been against cloud control since the early days. I'm a network engineer now, so for me it's first/second-nature.
I use locally controlled everything, with knockd to only open ports to specific /32 addresses as long as the knock sequence is complete (which prune every 24 hours). I follow this by a limit for the knock and dummy ports to lock the system (like honeypot).
I also have some "cloud", that I've stuck behind another firewall and don't allow network connectivity out of my home network with strict -J DROP. This makes it a nuisance to try and use IoT apps, but that's fine for me.(TUYA has been replaced by tasmota)
Home network is further secured from non-established connections to these devices to prevent any scanning or future devices being added to this "MZ" network.
Many thanks for your feedback!
After a long time ... Great.
Yeah - I have been very busy… glad you like it!
A 24 min video for a 25 EUR router. Really worth the money, thank you!
Thanks for the feedback ;-)
Such a great content 😊.
Thank you very much;-)
You’re the man, Marc!
Thanks mate!
what a comprehensive take down!!
Many thanks - I am happy that you like it ;-)
No phone-home here in Eschede (NL) 5x archer-C7 with openwrt, the only problem is the limited 5GHz channels, but now i know which to choose :-) thanks for his channel, verry usefull
Many thanks for your feedback Robert!
thanks for your hard work it's clearly that xiaomi collect data 👍👍
Oh yes - and they do tell you so. So from that perspective - they don't do anything wrong ;-)
Good to see you posting vids again, Marc. I bought one of these routers after your vid. Price was about $42 USD
Hi Vince, many thanks ;-)
thx for super review and test,here in EU Croatia on BF costs about 20usd ,seem like good deal now price is about 30usd
Awesome - many thanks for your feedback!
Liked right after you started that you wouldn't like anyone else controlling your own hardware!!!
thx, great video. please do the mesh over openwrt video
Will do 😉
I am using one of these as an AP. I get peaks of about 400Mbps download over 5GHz 802.11ac, and average between 100 and 300 Mbps, with -40dB RSSI (iperf3). The coverage is good, much improved over my two previous WiFi repeaters (a DLink and a Asus RP-N12), and supports over 16 devices all over my two floors.
Great feedback, many thanks Miguel!
Well explained , i really would like to have an easy explanation about the protection efficacity of routers , thank you
Many thanks Likaa - by protection efficacity you mean if it is actually possible to break into a device from the outside?
This is one of the best channels for openwrt and networking in general.
Thank you very much ;-)
Hey Marc nice content as always. i have few of these devices flashed with WRT. The one currently i use is XIaomi R3p. Could you make a test with this?
I’ll give it a thought 😉
Hi Marc, very nice video!
One general question: which software are you using for making your animations (eg. at minute 10:24)? Is that software free? If not, is there any free software that you could suggest?
Thanks
Massimo
Hi Massimo, I am using Sparkol Videoscribe. It is not free unfortunately.
@@OneMarcFifty Thank you Marc! I will have a look
09:40 only learned of this phoning home via my Pi-Hole. bought a security cam that i setup only to work with my Synology Surveillance Station yet it kept pinging back to the manufacturer every second. camera still worked after i blocked that on the Pi-Hole so that's good at least. but its skewing the blocked stats on the pi-hole, so i setup a no-forward DNS server in my router and setup the cam to use it instead as a DNS and it worked. then i realised simpler solution - setup the cam to point to itself as a DNS server 😁. i bought 2 other cheap cameras that were totally useless blocking traffic on the pi-hole.
Oh - clever giving it the localhost as dns! Yes, I did discover how nasty my Samsung TV and DVD player are with DNS filtering as well - the modern devices are really chatty!
Hey there! Thanks for the video. It is really helpful and I appreciate the quality of the production. It is a delicacy to enjoy.
I am considering getting a router with OpenWRT support. I have a 35/8 VDSL connection so bufferbloat is a great concern of mine. I will use SQM and ad blocking packages with the openwrt. However, I couldnt choose between Archer C7 and Xiaomi 4A. Is there a marginal difference between them to justify the price difference in a tight budget? Thanks a lot.
The Xiaomi has the stronger CPU. I would probably prefer it for that scenario if you can live with the limitations ( number of Ethernet ports, no wall mount etc.)
@@OneMarcFifty Many thanks.
Cooooool! The pronunciation is quite good! There is only 16 MB flash of R4A Gigabit. So better choose Xiaomi or Redmi AC2100 which include the same CPU MTK7621 & much more flash with 128MB.
Xie xie Vincent ;-) I'll have a look at those !
@OneMarcFifty
Thank you very much Marc. I have been actively following your channel and also Im part of your discord channel. This video was extremely useful and I love the way you take time and explain stuff. I have been using 3 of these at home and have set up a WDS and a MESH connection as the 2nd router doesn't have a backup power connection and if there is a power-cut the 3rd and the 1st connect using MESH temporarily. Waiting for your guide on setting up the MESH on this router. Cheers!!
Many thanks for your feedback!!
Hi Sir,
I was looking for a video like this many thanks for the video.
I'm not good at this networking. I'm also having a doubt here. Could you please tell me the that, if I connect 2 devices in to LAN port and tranfer data between them. I can get data transfer speed nearly 1000mbps? Or it will be shared between both devices?
I could see the swtich test speed but didn't understood.
TY for the excellent content you always provide.
Ans.1 Yes use lots of IOT services 15+ since i use a smartphone!!! Can we control our phones phone home and at the same time use all services they provide? Yes i know we can do so... but then..? there is lot of hard work to be done to establish etc for GPS service as maps or fitness tracking. So many to talk about it.
Ans.2 Privacy...so far at least 15+ people on the world know exactly whats happening in my house but mostly outside ;-) its fine to me that a Chinese guy know what time i switch on my lamp switch..and another know whats happening outdoors from my camera... but we talk for different people who can have access. Combining all these services under one authority..that makes me terrified and if this authority called Government we are doomed. Lots to talk about it.
Ans3. IOT routers already established. Since there is no sniffing or other processes that also would blow CPU usage as some of the internet usage too... i am fine with that! for the same above reasons spoken above. (cheap devices.. i don't believe could be used to monitor peoples privacy that could pass unnoticed.
Everything - traffic is encrypted nowadays. The only thing i hope is that these companies offer IOT take good care of protecting our Data first and privacy second.
Didn't watch this video, but thanks to you i flashed my router with openwrt a week or two ago and solved so much problem i had with original router's firmware. And after that you releasing video about my router's model. Holy cow.
Hey Alexey - I am glad that I could help you solve the challenges that you encountered!
I was looking for a router that works well with some open source FW because I don't like calling home or potential backdoors, and I want timely security updates. It so happened that this router was highly recommended on some list (was it even yours). For a small home network it seems to fit the bill perfectly. I got it for less than half the price you quoted in the video, but that must've been a special deal.
I think I decided that OpenWRT is the FW I want to got with after watching your video. It was only after that that I started looking at suitable HW.
Btw, I believe that the first 'i' in Xiaomi is supposed to be skipped over. Otherwise it sounds good to my ear.
Many thanks for sharing;-)
Very good!
HI MArk!!! I'm glad to wath your videos!!! cna you make a control parental filtering on openwrt. I would like to know the options. Firewall filters or DNS filters could be nice. Thanks!
Hi Sid, many thanks for the feedback. I have taken note of your suggestions.
Great video. Learned some linux stuff. Have xiaomi redmi ac2100 and it has some issues with builtin openwrt drivers. Is there any tips how to get drivers from original firmware and install it to openwrt?
I dont have a Xiaomi router and I wont buy it eityer. Yet I am watching this at 7.30 in the morning hoping to learn something new. Your videos are such informative. Keep up the good work, Marc
Many thanks for your feedback ;-)
thank you
Hi Abdull, you're welcome!
Marc: What do you think about creating a video where you run x86 OpenWRT as a VM in Proxmox or KVM which itself is running on one of those nice, power-efficient MiniPCs you showed earlier. Proxmox/KVM connects to the WAN or modem and routes the traffic to the rest of the system/nodes
I kind of did that already in the MPTCP lab videos - the edge router is an OpenWrt VM ;-)
Hi marc thanks for information you share. I have 2 question
Did you find a way to enable QOS in hardware offload?
And is wireless coverage difference between orginal and openwrt?
Hi, I haven't followed up on this further for the moment - I would really need to have some spare time for that ;-(
great content
Thank you very much!
Yes, the One is back! :-)
I told you guys I’ll be back 😂
Marc I saw the mesh video on this router, would you build a mesh network entirely made of 4a units? or it can't work as the main one and just as "dumb" APs?
Thanks for the good video. I bought a Second hand one for even lower price and flashed openwrt.
For whom facing Broken Pipe in idle connections with the used of this router, please disable Software Offloading.
Thanks for sharing !
I'm still waiting for you to do an openwrt install on a routerboard RBM11G which has one PCI port, two serial board connections, and one POE lan port. Shell setup of a server to hand out IP addresses and some testing! Love your video's.
The router is sleeping in a carton box together with a banana pi r64 and an aPU4d board - waiting for me to take it out and make that video ;-(
Awesome one.
Many thanks !
I Had issues with my router r4ac crashed at least 2-3 times daily. After installing openWRT works perfectly
Awesome, thanks for sharing!
I actually have the same router nice!
Great - thanks for the feedback ;-)
Hi Mark. I followed your video and created a network with a pfSense firewall and 3 OpenWrt Dummy AP with these devices. Is there a way to configure VLANs without the luci menu option that is missing from the 22.03 OpenWrt. Thanks a lot for your educational videos.
Hi, please see this video here for VLANs in OpenWrt 21 and above: czcams.com/video/qeuZqRqH-ug/video.html
Another outstanding video Marc! Can you provide your backup? I've lost my stock backup on a sdcard card that gone bad :/
Thanks!!
gee - I am afraid that I don't have it any more ;-( But you may try the debrick tools on Hoddy's blog: hoddysguides.com/xiaomi-debrick-tools-all/
You pronounced Xiaomi better than 99% of the CZcamsrs out there 👍🏻
Thank you ;-)
great job. changing wifi output power in openwrt can make difference in speed /distance compared to stock firmware?
It can - definitely - but usually people tend to rather turn up the Wifi power too much when in fact they should lower it for better roaming. For my tests it didn’t matter as I was only a couple of feet away from the AP.
@@OneMarcFifty 👍 i've read part of the openwrt discussions about this router, and people mentioned that wireless functionality over long distances(and behind walls, etc) is better in stock firmware so i'm curious if it's true or not. is it possible for you to test that?
@@metinik8528 I’ll see if I can check
Marc, would you know if the V3 currently being sold is still compatible with openwrt and easy to flash? There is a big warning on the device's openwrt page, that got me unsure if it's still a good buy even for an extender.
No sorry, I don’t have any of those - in general however - if there is a warning then chances are you will have to spend a lot more time or it will not work at all…
I know this is a bit late but I am working on a platform that controls devices from the cloud. However, I myself wouldn't want to operate in this fashion. We have a lot of users who wouldn't even understand logging into their router and making any changes. Either they are too nervous or just don't want that complication in their life. Most people are very comfortable using a mobile app that has very simple instructions and alerts. "Your Internet is not currently available, please do X, Y or Z." "There was a few requests for adult content today from this device..." I think you get my point. You, like many of those who watch your wonderful videos are very technical in nature and can grasp the finer points of network security and network configuration. Simplifying it for those who can't seems to be a good trade off for them. How many iPhones or Android phone are roaming around the planet, right?
I think that you are absolutely right. It is always a trade-off between privacy and control over your devices on one side and ease of use or comfort on the other side. I think the key differentiator is whether you trust a provider or not. Or alternatively - if you do understand the implications. Many thanks for your feedback!
Great video. Yesterday I was looking for a new router for my brother. I wonder between Netgaer r6220 and Xiaomi 4A GE. The price is very similar. Netgear is MEdiaTek with single core, Xiaomi MediaTek too, but with dual core. Like You've said without USB and only with too LAN ports. Netgear have USB and 4 LAN ports.
Yeah, it’s a pitty that they did not put a dual core inside - it has more ports, usb and more RAM…
Yes, it's a pitty. But I was reading, the Netgear is a good choice to ISP bellow 0.5 Gb.
Yes, I too am concerned about IOT devices, 'smart' TVs that don't get updates and the sort. I don't want a cloud-connected refrigerator, dishwasher, coffee machine, etc.
MAny thanks for your feedback !
Hey little tip: reduce the light shone on the greenscreen to minimize the amount of green light reflecting on the back of your head :)
Great advice- many thanks - I’ll give it a shot in the next video!
Thanks for your video. No, I do not use any cloud services!
Hi, many thanks for the feedback ;-)
A bit off topic, could you elaborate on the fact that the overlay file block (mtd/7) did not match the hash, and how you knew block 7 was an overlayFS, and block 0 contained all the others?
I'm a relative newbie to linux, filesystems and networking in general but am interested to know more.
Thanks!
Hi Jonathan, actually it was mostly common sense. I compared the volume sizes of the mtd blocks and figured out that mtd0 is as large as all others together. Running the "mount" command showed that mtd7 was mounted as overlay.
Hi, Marc! I'm going to put an OpenWrt router after the ISP's fiber router (thanks for your videos, it really helps a lot). Unfortunately, the ISP doesn't allow Bridge mode on their modem router (I think a lot of people have the same restriction from the ISP side). So, the question is what is the best mode for the 2nd OpenWrt router:
a) to use a "Router" mode (but to deal with the dual NAT).
OR
b) to use it in "dumb AP" mode (but as exception to enable/configure firewall on AP).
P.S> I saw your previous comments that you're using option "a" in your home network (your home network starts after the ISP's NAT), but could you please share a feedback what the issues you faced with dual NAT? Thank you.
Actually I don’t have any issues with double NAT - I even do IGMP proxying on the second (OpenWrt) router in order to stream iptv
@OneMarcFifty 14:15 Personally I do not use any IoT devices, that I access outside of the home network. I do find that it is a double-edged sword, and there are some things you can do to make it more secure, as I am sure you are aware.
Thanks for the feedback! Double edged sword- that’s exactly how I feel - you get tremendous advantages but you potentially pay a price for the comfort you get - I guess it’s just a fact in life - there is no free lunch ;-)
Hi Marc, thanks for this great video. Could anyone tell me how to use those mtdblock files to go back to the Xiaomi's firmware?
Hi Parth, in _theory_ you would do "mtd -r write (dumpfile) /dev/mtdx" in order to reflash the mtdblock to the device. But this is totally untested on my side. This article has some more info openwrt.org/docs/guide-user/installation/generic.uninstall
Can you review cheapest wave 2 router as mi4a giga is wave 1 ? Also difference between wifi 5 w1/w2 and 6 - reallife speedtest and if we should upgrade to wifi 6 for better handling or multiple users.
Need to check - I am not sure if it can do 80+80 or the like (the DIR-2660 can). I’ll update. I wanted to examine further on MIMO, MU and beamforming anyhow ;-)
Great video daddy! This router model is ideal for building a VPN router that beats any DPI firewall such as the Great Firewall in China. However, the past couple of Chinese firmware versions have patched the OpenWRTInvasion exploit. Any ideas how to downgrade their stock firmware?
Hi, my pleasure (lol) - maybe check out hoddie’s web site - I think he provides some tools for emergencies
It seems that the new models have the EN25QX128 chip and until a few months ago openwrt could not be installed, this week I will buy a model and I think it is already possible according to what I see on github, do you know if this is possible?
From what I see in the ToH openwrt.org/inbox/toh/xiaomi/xiaomi_mi_router_4a_gigabit_edition they say it’s not possible. But I haven’t checked the latest dev news on that
thank you for the info. can you show us how to connect to luci from distance safely?
Hi John, obviously you could use Wireguard or Openvpn on the device, but nginx/reverse proxy is on my list. Might do that with X.509 client certificates and luci.
Any chance we can have a proper restore to stock video tutorial? Or if Marc or anyone has a link that you can share, on restoring to stock procedure?
