I have a Windows 7 machine that also has Ubuntu on it. Yesterday the NIC spontaneously crapped out. I went and got a Dynex PCI NIC and set it up, my computer now finds networks but lists them as "unidentified" with either "no internet access" or "no network access".
I can't seem to detect other computers on the network either, so I do not believe it is even properly connecting to the LAN.
Things I have tried:
Reinstalling/Updating NIC drivers.
Restarting Router
Restarting Modem
Hooking desktop directly up to the modem's output (no router in between)
ipconfig /flushdns
netsh winsock reset
ipconfig /release (gets an error, doesn't complete) ipconfig /renew (gets an error, doesn't complete)
Trying to connect on Ubuntu (NIC is detected succesfully, but no connection is made)
Running the computer on an entirely different network (same ISP though, but one is a business connection and one is a personal/home connection)
setting up ipv4 info manually with static ip
connecting via WiFi adapter
connecting via Android phone w/ internet passthrough feature (detected as a network adapter, drivers installed, network found, exact same issues as with the NIC and the usb adapter)
WiFi on different networks
The only thing I can think of at this point is maybe a service running on the computer that is causing issues. However, I did a restore to 2 days before the issue began, and the problem is the exact same, not to mention it won't connect on ubuntu either.
Any ideas?
