Asoka Pluglink 9650 not connecting me to the internet

[lehrhard]

I recently switched to ATT UVerse and they connected my desktop in my bedroom using an Asoka Pluglink 9650.  It worked for the first day or so perfectly.  But now it only works for a half an our or so before losing connection.  Sometimes I will check multiple times a day and it will never be connected.  I need the internet to do homework and i need it fixed soon, but I have very limited computer knowledge.  Any help would be greatly appreciated.  Let me know if you need any more information about what I am using.

Thanks

Oh forgot to tell you guys that I am using Windows XP
