Hi,
I have problem with the wifi module.

I have two boards, one A-20SOM204-EVB and other custom made. With A-20SOM204-EVB I can see the wifi networks and with the other not.

I check all the connections and the only diference is that the wlan0 became DISABLE in the custom made board when I run "sudo lshw -C network":

A-20SOM204-EVB:
  *-network:1
       description: Wireless interface
       physical id: 7
       logical name: wlan0
       serial: cc:d2:9b:4b:de:7b
       capabilities: ethernet physical wireless
       configuration: broadcast=yes driver=rtl8723bs multicast=yes wireless=unassociated


Custom made:
  *-network:1 DISABLED
       description: Wireless interface
       physical id: 7
       logical name: wlan0
       serial: 58:b3:fc:29:7c:77
       capabilities: ethernet physical wireless
       configuration: broadcast=yes driver=rtl8723bs multicast=yes wireless=unassociated


I use the same A-20SOM204 board and the same SD card ( with Linux Olinuxino 5.2.5 ). Why the ubuntu is disableing the wlan0 ?

And anyone knows how to enable ?

Thanks.

Did you try software ways to enable it? Like:

nmcli radio wifi on

rfkill unblock all

etc.
