[Solved] Archer C7 V2 - Wireless Died: daemon. notice hostapd: handle_probe_req: send failed

Installing and Using OpenWrt
1

I'm running an Archer C7 V2 as an AP. Today, my wireless just died and the system log showed the following error: "daemon.notice hostapd: handle_probe_req: send failed".

I am running firmware built from the Master branch (built yesterday afternoon).

Set country on radio1 as well.

You could try fixed channels instead of auto. But overall it just looks buggy. Which ath10k are you using? The ct but not smallbuffers one may be running into a RAM limit.

3

Thanks for your reply, mk24. I'll look at the country for radio1. I've also set my channels for both my 2.4 and 5 GHz channels.

Right now, I'm using the non-CT versions of the ath10k drivers:

root@OpenWrt:~# opkg list-installed | grep ath
ath10k-firmware-qca988x - 2019-10-03-d622d160-1
kmod-ath - 4.19.123+5.7-rc3-1-2
kmod-ath10k - 4.19.123+5.7-rc3-1-2
kmod-ath9k - 4.19.123+5.7-rc3-1-2
kmod-ath9k-common - 4.19.123+5.7-rc3-1-2
kmod-phy-ath79-usb - 4.19.123-1
root@OpenWrt:~#

--EDIT-- I'm going to try using the ct firmware with smallbuffers and see how that works.

4

Well...using smallbuffers and ct firmware completely borked my wireless. So, I've flashed the provided 19.07.3 file for Archer C7 V2 without keeping settings and did a clean configuration. I'll see how that works for now.

5

It appears that a clean install of 19.07.3 has fixed the problem. I will mark this as solved.

6

Glad that fixed it. Wanted to ask if you still get one of the error notices you had been getting. I'm getting it now, using a newer snapshot, also on a C7, and I don't recall seeing it before. I'm trying to figure out if it's an issue or not. I don't seem to have any operational issues, though.

Did you see this still with your now working 19.07.3 setup?

I'm just starting to use this (June 4th) version, so we'll see how it holds up. Earlier versions and I've had the long running random wifi goes away problem that many have been having, though with an April 5th snapshot it's seemed to occur less often.

That's all my entries related to netifd in the System Log. I haven't seen any any errors regarding netifd yet.

So far, the 19.07.3 release has been rock solid - more solid than other builds and definitely more solid than my latest master builds. (I think they may be doing some changes in Master that won't play nice with my Archer C7 v2 right now.)

Interesting... You did have that in the first post block of stuff from the snapshot version. I still haven't had any major failure of the wifi system, excepting the occasional 2.4ghz radio (N) temporary dropout that many have on the C7. It seems to be a bit better with the newer (April 3 and June 4) snapshots, than the 19.07.2 I was running. I've been seeing it every 2-3 days, to maybe 1-2 a week now... hard to tell when it sometimes does it for just a short time, and fixes itself.

Kind of an ominous sounding error, but so far, I haven't major radio issues.
