Dear All,

After blaming:

- networkmanager

- ifupdown

- systemd

- my router

- my provider

- myself

 

I tested with a separate wifi AP (not managed by my provider) and sprdwl_ng crashes to the point of being incapable of "seeing" any network again (until rmmod and insmod) when the same ESSID is broadcast both under 2.4Ghz and 5.5Ghz

 

My wild assumption is that this driver doens't like (buggy perhaps?) to be "band-steered"

 

Whens ticking to a single band, no issue.

Hope it helps someone in my same situation

I have a similar problem with the official orange pi zero 3 image. It could also be band steering on my Asus XT8 mesh network. Wifi will stay connected for days and then drop out. I have noticed it occurs more frequently after I restart my router(s).

 

I wrote a simple CRON job to reconnect when wifi is disconnected however it doesn't seem to work.

 

*/5 * * * *  nmcli -t dev status | grep -q connected:Asus && echo "Connection 'Asus' is already connected" || (nmcli con up id Asus && echo "Connection 'Asus' is now connected" || echo "Failed to connect to 'Asus'")

 

  I hoped moving to Armbian would solve my problems however maybe I just make the above script reboot the machine on a less frequent basis when the connection drops. Following the topic incase someone figures out a software fix! Would much prefer being on armbian and glad to see there is now community support which wasn't the case when I last checked!

Hi Thomas, thanks for your report - I was thinking about a cronjob too o something that monitors dmesg

nevertheless, as a mitigation to avoid a reboot when wifi stops I can suggest:

 

sudo rmmod sprdwl_ng && sudo modprobe sprdwl_ng

 

Definitely not elegant, but gets wifi back from the dead until the next band hop

Hope it helps
