WiFi interface broken after update to 26.1

[lss4]

Same here on PC Engines APU2C4 and wle200nx card (Atheros AR9280).
The upgrade log is available at the following link, in case it is helpful:

Thanks.

I just checked your upgrade log. It appears you have the same issue I encountered. On line 2285, "ath0: only 1 sta vap supported".

However, looks like you have two Atheros adapter installed. The other one (ath1) is not reporting that message, but neither is working.

Can you check if you have a "wlan0" (and "wlan1" in your case for your second adapter) interface with OPNsense 26.1? You can use "ifconfig" from console but Interfaces -> Overview will also work. From my experience, those interfaces would be in a red "no carrier" state.

Would somebody check the logs for command errors? I have the feeling most reports around the last weeks omit obvious log entries in their installations.

I'm not seeing anything out of ordinary from that upgrade log, other than the line regarding "only 1 sta vap supported" which happened after finishing update from 25.7 to 26.1.

From my experience, that error message seems to be what was preventing OPNsense Web UI from adding new devices in Interface -> Wireless -> Devices. As soon as I tried adding a new device there and failed with error, I get that message printed on the console.

Still, I wonder what might be responsible for the creation of interfaces "wlan0" (without the ath0 prefix) that I saw with "ifconfig" or Interfaces -> Overview.

Are you referring to this commit? https://github.com/opnsense/core/commit/7e93cdb63f030

I'm not catching the error in either, which doesn't mean it's not there.

Might be worth checking the system log file as well for "ifconfig" failures.

After getting it to work with a lot of effort only to have it break again after not even a day when updating I consider the wlan support so broken that I am ready to give up and look for a more stable solution and use an external access point.

This is a common bad decision, using one device for everything ( many with me included have been there ), if it dies or issues, there goes the entire network.

Like Seimus recommended, I have an Asus RT-AX53U running openwrt for years now.
You set it and forget, the latest release is 24.10.5 but if you few up to some adventure, you can get snapshot or RC images.
