Odroid N2 Wifi adapter Module 5A stops working after update

[Walter Zambotti]

After an update to Armbian 23.05.1 Ubuntu one of my Wifi adapters no longer sees any access point and can't be forced to connect blindly.

 

The two adapters are very similar:

 

The two adapters are very similar:

Working Wifi Module 5B:

            |__ Port 2: Dev 9, If 2, Class=Vendor Specific Class, Driver=rtl8821cu, 480M
            ID 0bda:c820 Realtek Semiconductor Corp.
            /sys/bus/usb/devices/1-1.2  /dev/bus/usb/001/009

Not working Wifi Module 5A:
 

            |__ Port 4: Dev 10, If 0, Class=Vendor Specific Class, Driver=rtl88XXau, 480M
            ID 0bda:a811 Realtek Semiconductor Corp. RTL8811AU 802.11a/b/g/n/ac WLAN Adapter
            /sys/bus/usb/devices/1-1.4  /dev/bus/usb/001/010```

nmcli shows both devices

nmcli device
    DEVICE                   TYPE      STATE         CONNECTION
    wlx200bd04dc584          wifi      connected     asuszamb 2

    lo                       loopback  unmanaged     --

        

wlx40a5eff399ea is the device that has stopped working.

if I display the access points visible to each device:

nmcli device wifi list ifname wlx200bd04dc584
IN-USE  BSSID              SSID           MODE   CHAN  RATE        SIGNAL  BARS  SECURITY

The other adapter should show the same access points but:

nmcli device wifi list ifname wlx40a5eff399ea
IN-USE  BSSID  SSID  MODE  CHAN  RATE  SIGNAL  BARS  SECURITY

 

Attempting to make a connection via the not working adapter results in:
 

nmcli con up 175a67a0-d58d-4ebe-8d02-6f3c741c460b ap 3C:7C:3F:6B:EA:2C ifname wlx40a5eff399ea
Error: device 'wlx40a5eff399ea' not compatible with connection 'asuszamb'.
