Thanks a lot. I will build noble image and test today.

Here is another issue. I'm testing armsom sige5 with rtl8852bs wifi, which has two wifi interfaces: wlan0 and p2p0. At first login armbian can't detect SSIDs so I just press Enter for null ssid and password. After starting desktop I can't connect
wifi because there is file /etc/netplan/30-wifis-dhcp.yaml with following contents:

# Created by Armbian firstlogin script
network:
  wifis:
    p2p0
wlan0:
      dhcp4: yes
      dhcp6: yes
      access-points:
        "":
         password: ""

After deleting this file I can connect wifi.

At first login armbian can't detect SSIDs so I just press Enter for null ssid and password.

Maybe we need to

1. check if the network can be connected to with the given SSID and password (and only then create the yaml file, otherwise either ask again since user might have a typo, or skip connecting)
2. check for empty ssid/pw

Cannot tell anything here. Never used wifi in first-login and probably never will.

Maybe we need to

• if empty it re-cycle, exits after 3 cycles of selecting network
• also added several checks
• tested on dodgy wifi and it works as expected
• done many many tests.

Tested with rtl8852bs, I can choose which interface to connect wifi. Nice!
