I have a really strange problem that's similar to this. I can connect to the CGN3 with wifi and go online with no problems. When I connect through ethernet, I CAN connect to the router's admin panel AND Google search (and ONLY Google search, not Gmail, Google Plus, etc -- it's also not a cached copy, because I can search unique strings e.g. "dasg4tg" and come up with suggested results), but I can't connect to any other websites.
My MB is the Z97-Pro (Wifi AC) with an Intel I218V ethernet controller and updated drivers. My MB is about a week old and I connected through ethernet fine up until today. It just decided to stop working today.
I've tried rebooting both the modem and my PC multiple times to no avail.
Any ideas?
Thanks.
