Connection problem in every game? [HELP]

[lumune]

First of all you do know Hamachi needs open ports to work properly, right? If in doubt use Evolve, it's much better because it "punches" a hole through your router via UPnP so ports aren't a issue there.

Make sure WLAN is checked and also make sure you're not using any extra firewalls and have added an exception to PPSSPP on Windows Firewall when prompted the first time the emulator tried to get online.

I see you have tried with MHFU and Tekken 6 and it still returned the error. My guess it may be a firewall problem, either on your end or on your friends end.

MHFU and Tekken 6 doesn't require open ports to work so these games are preferred to test online connectivity for the first time.

Also, if you're on android i can't help you since i don't own one and some games that work on PC and a real PSP doesn't on Android or mobile devices, so i've read.

Good luck.
