Connecting to WIFI and Hotspot issues

[Alain Laverdure]

I just replaced my router with a new fancy one, and now my digipi would connect to it and revert back to hotspot mode.

after a bit of research on the net I found this from a website that the user was having simular issues .

 It helped me greatly and no longer have issues with reverting to hotspot and not connecting...

Create the file /etc/modprode.d/brcmfmac.conf with the following line:

sudo remount
sudo nano /etc/modprode.d/brcmfmac.conf  to create the file

"options brcmfmac roamoff=1 feature_disable=0x82000"  add this line without the quotes

save and reboot

This disables the SAE (WPA3 related) and SWSUP (authentication offloading into the firmware), and fast roaming.

Once this is done and my Raspberry Pi Zero 2W reboot it finally connected to the wifi.

Hope this helps others

great find.  that's the broadcomac driver, is this suitable for all Pi's?  I'm not familiar with the wpa3 stuff.

Incorporate in next build?



thanks!

Thx

I encountered the same problem when I recently upgraded my home WiFi router. I found the issue to be with the router and it’s “band steering” feature that wanted to communicate with my digipi using 5G. My previous router treated both the 2.5G and 5G as separate bands and I could direct my devices individually. The new router as currently set up doesn’t give me the choice but selects the band automatically based on signal strengths. When I get the new router to its ultimate location, I will reconfigure the router to disable the band steering feature.

That is a great suggestion also,  in my case i only had 2.4ghz only  and i still had the issues.  But i am certain different routers may have different features

that actually lines up with what usually happens. Newer routers come with things like WPA3 and fast roaming turned on, and the Pi can be a bit picky with those, so it ends up dropping the connection and going back to hotspot mode. What you did there basically tells the Pi to ignore those features, which is why it finally connects properly. I’ve run into similar issues before, so this fix makes total sense. You could also adjust the router settings (like switching to WPA2 or turning off fast roaming), but honestly your solution works just fine.

Great observations.

I need to fix the "fallback to hotspot" issue.  Once connected to a wifi hotspot, it should stay
connected or die retrying.  I have a little boot script that watches for wifi, if it doesn't see it, it
manually starts hotspot (in /usr/local/bin).

If there's a NetworkManager expert that enjoys embracing the horror, I'd be interested
in a fix (see /etc/NetworkManager/system-connections/ )

cool,
