Hi,

 

I have been running Armbian on OrangePi Lite for more than a year just fine. Then I decided to upgrade and flashed the latest version. Now with the latest version the device looses wifi every few days no matter which wifi device I use.

 

In order to investigate I have plugged additional USB wifi. Some time both wifi work. Then built-in may disconnect and stop working, but USB keeps working. Or vice versa, USB stops working, but the built in keeps working.

 

I have been able to send syslog to an external machine and here what it showed

 

Connection works fine:

The next day one of the connections stops working and complains that the WPA key may be wrong:

Obviously, nothing has changed, the hotspot is still the same and WPA key has not been changed. Both wifi connections are using the same key, and one works fine.

 

Rebooting resolves the issue, but after few days it is back again.

 

Anyone have seen this behavior?

Before downgrading to a version prior 2020 I'd like to check as much as possible if this is some bug

 

Thanks

I had to downgrade to last known working Armbian 20.05.1 Bionic version with this 8189fs module version:

$ modinfo 8189fs
filename:       /lib/modules/5.4.43-sunxi/kernel/drivers/net/wireless/rtl8189fs/8189fs.ko
version:        v4.3.24.8_22657.20170607

Now all works fine like previously
