I can't connect to the interenet using my wifi router (Belking N600). But if I connect my computer via wire through either the modem or the wi-fi router, it works. It is just the wi-fi having problems, again, if I wire-connect my computer to the router, then it works.
I called Belkin support, they said there are some "established foreign addresses" that have accumulated in my PC over time which are blocking the Wi-FI connection along with other processes. I do not know how to assess whether what they are saying is correct. To fix it they asked for $99 and I thought this suprising for Belkin customer support. Any help would be much appreciated.
