Hi,
I'd similar problems and I've found something in the freebsd forum. I've tested the approach on pfsense and it looks more stable and reliable to me. Maybe it's an approach for opnsense too.

Create the file
/etc/rc.conf.local

with the following content:

Code: [Select]

ifconfig_ath0="ssid speedy.i mode 11g mediaopt hostap channel 2 -bgscan up"
Here is the link to the forum post:

Maybe it's not exactly what you want, but it helped to get my wlan more stabe and get rid of the stuck kernel messages. At least, the number of message with stuck_beacon became less.

A feedback would be nice!

I wrote to varia.store, where they sell the OPNsense routers and the answered, that they know about the issues with WLAN in the current 16.7 release (especially with virtual WLANs) and problems should be gone with 16.7.7. ... i will wait for that update and see what happens. Otherwise i will test your suggestion.

Best, hirschferkel

Hi hirschferkel,

I don't know about 16.7.7. 17.1 is more likely. You could try the beta, ath works a lot better there. This has been confirmed already.

17.1 will be officially out end of January.


Cheers,
Franco
