24.7 Production Series / Re: Kernal Panic - WPA broken for wifi after 24.7 update

Are there any other options to try?

I agree with everyone here that FreeBSD should not be used as WiFi AP. However for logistics reasons I have some advantage in having a single piece of hardware working as Firewall/Switch/AP in my homespace, and up to now an OPNSense mini-PC has worked wonders for my needs.

I was able to make my "Ralink 802.11 n/g/b Wireless LAN USB Mini-Card" work in OPNSense 24.7.1+ by disabling both WEP/WPA and keeping the WiFi SSID hidden and somewhat randomly generated. Obviously the client devices must support WiFi Access Points with a hidden SSID.

There is an obvious security hole in having no WEP/WPA auth, that I partially covered by having the SSID randomized and hidden and allowing the DHCP to only accept known clients, so I would not suggest this in a professional office environment. But for my home network this config worked with my WiFi hardware, and allowed me to quickly restore the WiFi connectivity, so I thought to mention it here.
