This problem has been going on for a few months now. After failed troubleshooting (time and again), I'm finally giving in, and asking you for help. I would like to prefix this by saying that Ubuntu is now the operating system I prefer and use regularly.
I have scoured the askubuntu forums and have tried many of the solutions offered, yet none have solved these problems. ndiswrapper does not work, either.
Any help with this problem would be greatly appreciated :)
Edit 1: As a bit more detail, my wireless can only connect to 1 router (ssid: NETGEAR-2.4G). I can't connect to the second router in our home (ssid: 4NXG). I'm using my wireless connection to reach these forums, but Ethernet still does not work. I would like to resolve the Ethernet and Wireless problems, if possible.
Edit 2: On Elder Geek's advice, I'm editing this question to only deal with the ethernet problems.
Edit 3: Added additional lspci information, as requested.
Edit 5: Added even more info, zomg so much info
Current Problems
- Ethernet shows "Connected", but there is no connectivity. Rarely, ethernet will start working out of the blue. Then immediately stop working again.
- Router sees my computer (when accessed remotely via 192.168.1.1)
- Pinging google.com or any ipaddress results in packet loss.
- Port forwarding does not work
Symptoms (Timeline)
January 2015 - Linux Mint Rebecca Installed. Wireless worked fine, Ethernet worked fine.
Early February 2015 - Port forwarding suddenly failed.
Mid February 2015 - Wired connectivity failed. Only wireless works.
I have installed Ubuntu 14.04.02 (current OS), Debian 7.8.0, and Linux Mint Rebecca. All fresh installs have failed to achieve Ethernet connectivity.
While connected to the Ethernet, the wireless router sees my computer, and my computer says that it is "connected". Yet all queries of any webpage simply times out. Pinging google.com results in 100% packet loss.
