how dare you?
Showing these obscure networking terms in a simple way. Nice work! Learning lots with your videos!
Thank you so much! I'm very glad you found these videos useful :-)
Thanks for making this video, helpful for others. Wish found this information months ago since I had been having issues with wireless clients disconnecting because of DFS channels and couldn't figure out why, till two months after.
Had searched around and found this information.
You're very welcome! I'm very glad you found this video useful! Cheers :-)
Thank you so much!!!
Always learning new things from you!
You are so welcome! Thanks for watching :-)
I haven't tried this but it makes sense and fits my current problem. Many thanks for bringing this up.
Thank you for this great video. I live next to an airport and have those issues from time to time. Gotta get into this problem....
Glad it was helpful! Thanks :-)
OMG!!! You're the hero! I've dug through the whole internet and I've been fighting the same issue for years!
I live about 8-9 km straight from an airport, which might be far enough, however... I'm RIGHT in a damn axis of the main runway. I've been using higher channels on 5GHz due to some extra power it gives to boost the signal and it was fine, except sometimes it was going off just like that. Sometimes it came back and sometimes stayed off, untill I switched it manually.
Now, since the airport is quite distant and shouldn't be interfering, then what might be causing it? After watching your video I came to an idea and did some testing. The result seemed both: odd and obvious at the same time:
it is those damn planes that sometimes go quite low above me (since I'm in the runway axis) that cause my 5GHz wifi drop randomly... O!M!F!G! Thx again.
A customer here in Stockholm who uses TP-link WiFi Deco's has the same problem, usually every night around 19-22, when the planes fly over their apartment, to and from Bromma airport. In TP-link Deco's it is not possible to change which channels it uses.
The sellers of TP-link Deco's do not mention this "feature". It's better to be honest, than to get disappointed, and ultimately angry customers.
Thank you! I am learning a lot with your videos. I am glad i got the same router as you. I am a tech support myself. Great work i am now a subscriber
Great to hear and thanks for subscribing :-)
You my friend are Very Good at delivering your content. Candid and easy to understand. Thank you and keep creating more contents.
Thank you! Will do!
Dude, I love your videos. Thank you for taking the time to make them. I learned something new today. 👏🙌😃
Glad to hear that, thanks 😀👍
Very useful to me gaining me ideas on future use... Thanks...
Cool! I'm very happy this was useful for you! Thanks :-)
I am working on getting A+ certified and one of the things I have to learn is this. Very well explained. Thank you.
Glad it was helpful! Good luck with your A+. I didn't know DFS was in A+?
We have to know about 802.11 channels and frequency
WiFi Analyzer Tools or a good Spectrum Analyzer helps to spot things like this. Good Job on the explanation.
That's right! Thanks :-)
Just what I was lock it for. Thanks a lot, HAG1!
Glad it was useful for you. U2!
Thank you. This is very useful information.
Glad it was helpful!
went down this rabbit hole a few days ago, wish i found your video then:(
It's indeed a rabbit hole, if we don't know what exactly is going on 👍
You surely helped me quite a lot. THANK YOU. I just subscribed BTW.
I'm glad I could help and thanks so much for subscribing 😀👍
Isn’t 5g bad?
Great video, I live in an apartment and DFS is a life saver. I hope there is no RADAR around me (Cross fingers)
This video is GOAT I have the same problem and live down the street from an airport
thank you, i found out there is one of the question in new CCNP exam
I like all your videos especially the way of presentation
Thank you so much! I'm glad you liked the videos :-)
@@Behfor Thanks .. You really deserve more appreciation.
I wish my router logged in the detail to say that it detected a DFS eventbut I am close to an airport so this is great to know. Also I was considering using DDWRT firmware on my R7000
Now I know why my Asus router has those missing 5ghz channels. Awesome!
Glad this was useful for you 🙂👍
the presentation is lit 🔥
Glad you liked it thanks 👍
Called it! The Merlin firmware updates are a godsend. It also solved a pesky disconnect problem with the USB port when streaming video from an attached HDD.
Wait, you can watch a video from hard drive from your router to anywhere in your house?
@@jimmylim5015 Yes, but there’s some configuration you have to do on your devices. I use my iPad with the VLC app to stream videos to it
Nice video. That was what was happening to me. Regular disconnections because I was using channel 64. I changed to channel 36 and problem got fixed 😎
Glad this video was helpful for you, thanks 👍
@@Behfor Yes, and thanks to you for sharing this info. I was using a 2.4GHz router for years and a week ago I bought a new WiFi 6 5G router. The difference in speed is really big, and since I started using the 5GHz band in channel 36 I got absolutely no disconnections. I turned the 2.4GHz band off as all my devices support WiFi 5 or WiFi 6 😎
Great video my good man.
Glad you liked it! Thanks!
Excellent video
Thanks, glad you liked it.
It's a good thing that not many people are aware of the unofficial firmwares one can flash on these routers to bypass F©©'s frequency lock, at the end of the day it's just causing inconvenience to us users.
you are a great teacher!
Thanks so much 👍😀
I took me alot of research to find out why, and stil lso few video information about it.. I am happy to see I was not crazy !! my channel 36 of the 5ghz in my canadian city(sector of Montreal) does not work!
I had a working aimesh network comprised of an Asus RT-AC68U and a TM-AC1900. I flashed the TM-AC1900 with Asus firmware and created the aimesh network quickly and easily. Subsequent firmware upgrades from Asus rendered the aimesh network inoperable. Do you know if Asus started cracking down on hacked Cellspot routers? Do I have any other options to get it working again? Thanks and you're doing a great job with your tutorial videos.
Interesting. I too had a 5 Ghz disconnect problem between my RT-AC68Us. I did solve the problem, but it had nothing to do with DFS channels. Turns out this problem is well known in the world of Asus RT-AC68Us. The problem is with the Asus implementation of Bridge mode (at least for firmware 3.0.0.4.384_20648). The workaround is simply to use Repeater mode instead. Same wireless parameters, but Repeater mode is rock solid. With Bridge mode I could have 5+ dropped connections per day. I have not had a disconnect since running with Repeater mode. Asus might have fixed this in later firmware since a lot of folks brought this to their attention.
Thanks for the knowledge drop
You bet!
@@Behfor does the Merlin firmware have auto updates? Can I also use the Asus Router App if I install Merlin?
Installing Marilyn onto Asus
I like to seek your assistance in providing me the step onto the installation. Especially downloading the Marilyn software and then follow the instruction for installation.
Bravo!!!!
Thanks!!!!
hey man. amazing videos! im having an issue though i was hoping you could assist. my house is in Malaysia. and im living nearby an airport. im facing the exact problem whereby the 5Ghz band of my AC86U would constantly drop after awhile, and my only solution was to reboot both the main router and the node (i have two AC86U connected via Aimesh using Ethernet). I was so excited watching your video thinking the DFS issue is what's plaguing my router, then u mentioned that ASUS router excluded DFS channels altogether (true enough, i checked my channel and there's no DFS channel). Do u have any other idea what else could be the problem?
I feel your pain. I had 4 different Asus routers recently connected in a number of AI mesh configurations with Ethernet back haul connections. Original configuration was a GT-AC2900 as the primary with 2 RT-AC86U as the Mesh routers. Massive problems, then I scaled back using just the 2 RT-AC86U's and I still had problems, fyou mainal configuration was primary RT-AC86U with a RT-68U as the Mesh router. Still had problem. After A LOT of testing it was found that there was no problem with the wired side of the network.
I was running into random wireless network latency locally, not a problem outside of my network. This latency manifested into multiple client disconnects throughout the day. Asus tech support was not existent. I tried everything I could. Lived with the nightmare for 2 months through many different firmware updates, still the same problems.
I believe there may be a problem with the Asus firmware and buffer loading?? I had not had chance to try Merlin firmware, I just gave up and moved to Ubiquiti and my problems appear to be solved. So I am not sure what Asus is doing but BE VERY CAREFUL with the AiMesh as a solution, I do not think it is anywhere close for prime time.
This being said, you may have a different set of problems, this was my most recent nightmare after spending a LOT of money on Asus and even more with Ubiquiti.
I actually have to use UMII-1 5ghz bands as my roku streaming stick can onky see 5ghz wifi on those channels
How long can your DVR record on 1tb before you have to start deleting footage
Thx. Bro
Having the same problem )) maybe this video can help
Made my net+ course thing waaaaaaay easier to understand. And unironically might be the answer to my internet problems as well.
Bought a 5Ghz extender. I was in belief that after years, protocol would be perfect, SoCs would be perfect. 2 days passed, everything looking good. 3rd day some random signal strength drop with some disconnect... I went through whole home to find out neighbor's brand new devices near mine (apartment flats, same wall outlets along Y axis). I turned off auto to choose channels and got this warning screen about DFS. Moreover my old Sony Z3C was only able to see the first few 5Ghz channels. So I am stuck to first 4 5Ghz channels. Same frequency range with my neighbor. Whole ac protocol feels like a rushed job for me right now. Even after seeing AX released, there appeared an E. Wish AX stuff were affordable in economically questionable countries. Q.Q
THANK YOU CANT SAY IT ENOUGH!!!!!!!!!!!!!!!!!
Great news with the new Merlin firmware.
Yeah it is indeed great news :-) Cheers!
How to access the channels page on the Asus router? And activate it
@5:43 what did "disonnected" mean?
😅
Please make a video about how to install best custom firmware on tplink re200 and archer c6 ..
no
I have a question. All my neighbours 5ghz channels are auto so they switch always so I don’t care about them. My question is. Do the lower 5ghz channels 36 and them. Have any differences to channels that are higher (like 149 and those ) btw I’m in Europe
DFS can valuable in the right crowded area. I live in a valley so DFS channels are good to go and help out at my crowded condo.

I got a question but it’s about DD-WRT and the 5GHz. Is it possible to have both virtual access points for the 2.4 and the 5 running at the same time, an$ if so how do you set it up
You just turn them both on
Is 5 g In the United States same as out side USA.
?
thnx a lot genius!!!
Thanks but I'm not a genius :-)
@@Behfor you are to me!
But what if there is no airport and no radar and 5Ghz is still disapparing a lot?
AP under Asus firmware sucks, I had no luck getting my clients to cooperate but AImesh under Merlin is working great!
Yeah it's been like 10 days that I installed Merlin and I'm loving it! Thanks!
@@Behfor since you are using merlin now can you test the performance of dns over tls using googles dns? I'm curious how much it slows down the web browsing experience.
Hi, wifi6 frequencies are also affected by this DFS problem?
wifi 6 5ghz also has dfs but wifi 6e 6ghz doesn't have dfs
What people tend to forget, because it's usually stated as he states it here, "to avoid interference with my neighbor's WiFi...";
well, if you're interfering with your neighbor then your neighbor is also interfering with you. So, even if you don't care about your neighbor, the problem affects you too. In the USA, the non overlapping 2.4 GHz channels are 1, 6, & 11 at a 20 MHz bandwidth. If you're in a crowded area, don't use the 40 MHz bandwidth on the 2.4 GHz band. If you do, you'll probably be overlapping someone and, as stated above, if you're interfering with them, then they are also interfering with you. So, you'll probably get better performance at 20 MHz due to the reduced interference. Also, while a clear channel is best, having 2 access points on the same channel actually causes less interference than having them on overlapping channels. Some newer devices are smart enough to realize this if you use the Auto channel selection; however, most aren't. So, do a scan of your area and pick channel 1, 6, or 11 for your 2.4 GHz band, whichever is the clearest.
As in the 2.4 GHz band, in the 5 GHz band, the wider the channel width, the more likely you'll walk on another device. So again, in a crowded area, don't run wider than 40 MHz. Once again, the reduced channel width's reduction in performance will probably be less than the performance reduction caused by the interference you get with the wider channel width.
Some devices, such as Mimosa radios, will lock out the DFS channels that it detects RADAR on so that it doesn't try to return to those channels, but will continue to use the other DFS channels.
Just get my new asus router and 5Ghz wifi keeps disconnecting, my home is not even near the airport, forced the channel to 48 and now everything works perfectly.
is that tomato firmware on 7:00?
No that's actually a Meraki AP which is managed through Meraki Dashboard. I explain Meraki in this video in case you are interested: ua-cam.com/video/4f04JT6vBNI/v-deo.html
I have the exact same problem. It keeps disconnecting from time to time, making UA-cam hangs or Plex completely stop working.
I just set channel to Automatic without DFS and I hope it works.
The problem is a while ago I changed channel to 36 and it kept disconnecting, so I don't know if this gonna work now.... but let's have hope.
Thanks.
Did it work?
@@AMVhuntingSyndrom it didn't. I had to cable the tv.
I have a public airport about 8 miles away and a private airport about 1 mile away.
Oops!! So definitely DFS channels are not good for you!
How do I edit out the DFS channels from Auto Select on an Asus A86U?
If you mean ax86u then it is mentioned in this video: ua-cam.com/video/nJ73NFHXJZo/v-deo.html
@@Behfor yes, I meant ax86u, thank you for the prompt reply
@@BudFuddlacker you're very welcome!
I live near one of the worlds 🌍 biggest airport, no wonder my 5ghz WiFi is SH’T
