I have a cable modem w/a Linksys wireless router and I'm not sure what the problem is. I have no problem connecting wirelessly through my laptop, but my PC won't connect at all. It started giving my problems connecting whenever it felt like and even when I was able to get online, it would suddenly stop working. Antivirus won't update, but the scans have come back clean. I've done the whole shutdown/restart, diconnect/reconnect,reset modem/router,checked wire feed and even replaced some of the wires.
