Hi folks. Any update on this issue? I have a r6220 with openwrt 19.07.5. I am putting off the upgrade to v20 after seeing this issue. Just trying to bump this up.

Is someone working on this? Or should we start editing mt76 devices on the wiki as not supported for v20 and v21?

candiesdoodle commented 2 years ago

Has anyone tried with snapshot with kernel v 5.10 or higher? read on the forum that it solved some issues related to speed, not necessarily related to this, but maybe worth a try?

Will see what happens, running it as dumbAP and turned of some services like led and firewall as they are not needed :)

EDIT: after 2days no drop and phy1 not tainted yet.. Looking good so far. My router reboots daily(my cronjob) and switching channels are on auto.

EDIT2: as far I see, there is no tainted crashes, however I still see drops of 5Ghz most likely due https://github.com/openwrt/mt76/issues/633

EDIT3: drops were solved by lowering the antena power due to previously mentioned bug limiting my max power, now the limit cannot be increased without flashing the ROM chip until upstream kernel fix is merged.

LZeugirdor commented 2 years ago

I'm running a weird setup where i have the router connected to another router via wifi, but 1 antenna is connected to the 5ghz (6220>main) and the 2.4ghz to devices on my side of the house. all in all it works great except when i get that error and 1 of 2 things happen, the radio crashes and reboots or the whole router crashes and restarts. i noticed this mostly happens during the daytime when there is a lot of activity. but at night it's usually perfectly fine.

I also noticed this interesting line, even though the tx power doesn't actually go up to 30 for me because the max is 25 for 2.4g and 23 for 5g.

Hi @freed00m,

I have 3 Xiaomi Router R3 and I would like to test the changes you've made. I am using the X-WRT firmware (fork from OpenWRT) and I'm having the same problems described here: WiFi dropping randomly. I know that the Xiaomi Router R3 isn't directly supported by OpenWRT because of the NAND, but I will try to use this script I've found (I don't know why this isn't already on OpenWRT main source code): https://github.com/XFY9326/Xiaomi-R3-OpenWrt-Stable Could you please share the steps you used to compile the OpenWRT snapshot with newer kernel? Thanks! :)

freed00m commented 2 years ago

@gitnewcomer I don not know how to yet, but I think you should investigate a README file of the openwrt package.

gitnewcomer commented 2 years ago

@gitnewcomer I don not know how to yet, but I think you should investigate a README file of the openwrt package.

@freed00m did you test it with the new OpenWRT snapshot available or did you compile it yourself?

freed00m commented 2 years ago

@gitnewcomer I used the precompiled snapshot, exact version mentioned in my post.

LZeugirdor commented 2 years ago

I remember reading somewhere that the issue can also occur with devices using wmm power save, I haven't gotten to test this but one way I've been able to test the drops is watching videos from YouTube or prime video. It usually happens then and either the radio will crash or the whole router will crash and restart.

LZeugirdor commented 2 years ago

@FusionDragon - this lower power is reported/discussed I think already in some other issue #227 (comment).

I read this but idk if it's the same issue, I don't think my power is low, I actually believe the power is inaccurate and higher than what's listed. I think that the radio is broadcasting too hard if that's possible and maybe that's what's causing it to crash.

This is what I have also seen on my Xiaomi Router R3: if I start demanding to much bandwidth, like streaming Full HD or 4K videos on Youtube, the WiFi will crash or the router will restart... I tought it could be a heating problem and added a bigger heatsink on both chipsets, but that didn't help. Then I tried to lower the transmitting power down, but this also didn't help. I switched to PandoraBox 19.01 firmware that uses the MTK binary for WiFi and I'm without drop outs for 5 days. But I would love to change to the newer OpenWRT and not rely on the MTK Binary... :)

I did it a little different, I thought it might be a collision issue because of country code and how high the dbm was so instead I switched to a higher band on 5g and lower band on 2.4g and ended up getting less crashes overall.
