Wifi access but no internet

[tobynz]

Hi All

Raspberry Pi model B
Pi powered from 2A USB hub
Edimax wifi dongle on hub
Powered USB 3.0 WD drive on hub

Have encountered a strange problem with my WiFi setup. I can connect to my home network and control my Xbian install via my android phone (Yaste controller for xbmc). The problem I'm having is that I cannot scan for new movies etc because it cannot find the host servers for TVDB and MovieDB. I also tried playing a trailer for a movie, still no luck, the connection times out. Its strange that I can work within the local network but cant access the internet. This setup was working fine when I built it at my work but now doesn't work at home - any ideas??

Cheers
