@dandy_j Can you run sudo rfkill unblock all (from the terminal, after exiting Emulationstation) and see if you can detect the wifi networks afterwards.
Is your WiFi configured for 2.4 Ghz b/g or it's just 5Ghz ? The PI only has 2.4 Ghz capabilities.

Hello, i guess i was talking about SSH. Im using WinSCP to log into my Pi.

When i type in //Retropie/ i can access the bios, configs, roms and splashscreen folder but i still cant see my Pi under network.

I managed to get access to all my files now. Had to add sudo -s under SCP/Shell options.

Good enough for me i guess. Thanks for the tip @mitu .
