Hello, I have constant issues with my wifi (the one where you can only access google pages and nothing else). I have tried many PC-end fixes online such as changing my DNS, firewall settings, ipconfig, flushdns, registerdns, and both ethernet and WIFI. On the router end, I disabled advanced security and made a DMZ port for my PC with no change at all. This is an issue not specific to my PC, however, it does not affect all of our devices at the same time; some may work fully while others either work partially or not at all. My only temporary fix on my PC end is reconnecting to the WIFI a few times or reinstalling my internet adapter until it works and it's very frustrating. Can anyone help me confirm that I have done all I can on my PC's end? Does anybody else have these issues with Comcast?
