HOME License on XG115 hardware network adaptor not working

Hi There

I recently acquired a second-hand XG115W. After wiping the SSD, I successfully installed the V20 HOME firmware on it. However, I've encountered this issue after the installation:

Ethernet ports 2 and 3 do not function.

I can see the activate light flashing, but it stops until the system reaches the password screen. The management web interface shows four Ethernet interfaces, but ports 2 and 3 remain inactive. I can see two interfaces in the management menu, but they don't work before login.  Only Ethernet ports 1 and 4 are working properly.

Also, the Wireless interface is not working too. 

Has anyone else experienced these issues with the XG115W?

Thanks in advance for your help!
