ATH10K wifi instability on TP-LINK Archer C2600

Hey there guys,

I am using my C2600 as a 'dumb' access point.

The issue i am facing is that it seems the wifi is very unstable on this router. An example of what happens is:

  1. I associate the client device with the router
  2. Internet and wifi traffic is OK
  3. About 10 seconds after the inital association, the wifi traffic seems to stop

Below is a logread output. There seems to be an issue with the ATH10K driver??

Hopefully someone can make sense of my issue!

Thanks

I'm running OpenWrt 18.06.1, r7258-5eb055306f without these options on C2600 and I don't have these problems. Do you really need legacy rates? I have set this option to 0.

Ok I have disabled the legacy rates option let's see how it goes

Even with legacy rates disabled i still am facing this issue. :confused:

I think the most interesting thing is that the firmware is crashing as stated in the log:

Mon Oct 15 18:21:17 2018 kern.err kernel: [107956.280645] ath10k_pci 0000:01:00.0: firmware crashed! (guid a36131f4-6331-4e39-a5ed-56219daddfae)

Does anyone have any ideas?

So I am still facing this issue so I'm reverting to the stock firmware

Current development snapshots have moved to ath10k-ct, while I can't guarantee this fixing your issues, there's at least a chance (you can also try different wlan firmware versions on your existing installation, without reflashing).

Thanks for that i will report back my findings!

EDIT: so the issue still persists

hi same problem on LuCI Master (git-18.296.76718-9deb5c1)](https://github.com/openwrt/luci) / OpenWrt SNAPSHOT r8378-9ac7350.

possible solution ath10k-firmware-qca99x0-ct-htt 2018-05-12-952afa49-1 ?

i had wifi connection continuously broken , after installing it is working for an hour no problems (i just tried ), i'm not hard skilled .

I'm also running 18.06.1, r7258-5eb055306f, with rock-solid wireless AFAICT. Sorry I don't have any suggestions to offer.

Same here!

restarted to break wifi, installed 18.6.1 all okk
thanks

I've had unstable wifi lately as well, I think it might be due to the new ath10k-ct driver as it was rock stable before.

Noticed the same thing!
Remove packages ath10k-firmware-qca99x0-ct and kmod-ath10k-ct, install the one's without -ct and wifi is stable again.

I can confirm, rolling back did the trick.

I also found that the ath10-ct firmware is terrible unstable!!! please change back to the stock firmware on the snapshot branch.

Fully agree with you!!!

There was some progress on ath10k-ct driver.
Seems to be stable now! :slight_smile:

Yep can confirm that the wifi on the c2600 is stable again

Still not 100% stable: Why the switch to unstable ath10k-ct?

The author says he found the cause of the last crash though so that might be fixed too. It's certainly more stable now than it was not long ago.

I have no 2.4G radio on a factory install of 18.06.2 on Archer C2600 1.0. Might this be related?
