I have a inspiron b130 notebook. after doing a system restore i can't connect to the internet. the computer says i have a connection both wired and unwired but the browser page won't load. the other laptop in the house is connecting fine so i know the router and cable modem are working properly. the router is a linksys ccg 200 and the cable modem is provided through comcast. is there a setting or something i need to check
