I have a problem connecting to the internet through my T-Mobile Sinus DSL Basic SE wireless router/modem:
I have 2 laptops, one is a Dell and the other is a Hi-Grade. The Dell uses Windows XP Professional SP2 whilst the Hi-Grade laptop uses Windows XP Home SP2.
When I plug the Dell laptop into the router with an ethernet cable; everything is fine I can access the internet.
Yet when I plug the Hi-Grade laptop into the router with an ethernet cable; I receive a 'Limited or No Connectivity' message and cannot access the internet.
When I try to access the internet wirelessly using either laptop; I receive a 'Limited or No Connectivity Message' and cannot access the internet.
I would be extremely grateful if somebody could shed some light on the problem and help me fix it.
PS. My ISP is T-Online in Germany.
