Windows 7, 64-bit. All wireless network.
Fine last night, no reboot, no internet today.
Shows connected in system tray, but with that exclamation mark. Will not connect to wireless router's IP address in browsers.
The other machine on the network - this one - connects just fine.
Rebooted, got "Windows cannot find 1683526.exe'. Make sure you typed the name correctly, and then try again."
Did a System restore to yesterday morning, same results.
Can't find "1683526.exe" on the Google.
Suggestions?
Routers are behind and under furniture, so haven't tried a wired connection yet.
