Really really in need of some expert help, a friend directed me to this site.

I recently got my Medion laptop and can't seem to get it to commect to my wireless network - which my old Medion laptop and my desktop computer do fine.
It's saying the Network is my BT home hub and that makes sense, and that there is a strong signal and all the rest of it but that there is limited or no connectivity, I've tried repairing it but it came up with an error message of "cannot renew IP address".
