Remote Play help - PS3/PSP

[garlad]

Have a question about the PSP Remote Play..

I can view and operate my PS3 through my PSP no problem while I'm at home (Connect via Private Network then Playstation(R)3) and brilliantly there it is on my PSP. I can watch videos and play games (High Stakes on the Vegas Strip:Poker Edition works perfectly by the way! Stored on my PS3 but i can play it on my PSP!) Anyway, i was away from home today and tried to connect to the PS3. I tried connecting the way i normally did it (above) but no joy, so then i connected via Internet connection but got an error. The WiFi signal picking up was only about 50%. I then came home and tried connecting via the internet (instead of Private Network), picked my internet connection and again it doesnt work. What am i doing wrong??

Thanks a mil,
