@neo207 Here:

;wifi.ip=manual ip address
;wifi.gateway=new gateway
;wifi.netmask=new netmask

The semicolon at the beginning of the line indicates that this command is not being used, to set the Ip manually you need to configure these 3 fields and remove the semicolon from the beginning of the lines.
If you don't want to test it, that's fine, it's just a test suggestion, as I said, I don't know what it can be and I'm proposing things that might be related, it's "trial and error".
