I’ve gone through that Wiki page before and I had successfully set up the wireless connection. I was able to update the versions and get a load of roms on. It’s only after a few reboots and a few days passing, no wireless interface anymore.
I used method 1 originally and it was working perfectly. I tried option 2 yesterday following a post on here. Neither have worked. I have a 5m ethernet cable coming today which should allow me to bridge to the router. I will then run another update just in case.
