I've tried every suggestion I could find. I did the winsock reset (over and over again). I've tried resetting TCP/IP. I've downloaded updates and different browsers onto a flash drive and then installed them onto my laptop. I've disabled all firewalls. I've enabled DHCP, which only gave me 168.x.x.x ips. Then I used another computer (LAN connection) to get the ip address, and manually entered it, then used the same cable, since I knew that was working.
Randomly, after hours of working on it yesterday, it connected via a wireless connection, but the connection only lasted a minute. I haven't been able to get any other connection to work since.
I can always connect to a router via LAN or wireless network, but Internet never works (except for that freak minute yesterday that gave me false hope). Any help?
