[arwynj55]

hi everyone im using xbian on my 512 RpI with wifi
im using this wifi adapter

Ive set it up correctly as you will be abil to tell from the pictures I have added

the problems I have is that I cant do anything that involves internet I cant download anything or view things (example: fusion.xbmchub.com I cant see anything inside it)

and if I try and download something from the built in stuff it says "downloading 0%) then it goes away

if I try to add a source (trying to get fusion) I get this error "Unable to connect, could not retrive directory information. this could be due to the network not beign connected" but I have set up the wifi correctly

if anyone could help me solve this issue I will be happy :3 Im using Xbian 1.0 alpha 5
I really need help here
