View Full Version : [ubuntu] Wired network has an intermittent connection

August 13th, 2012, 02:55 AM
Installed clean tonight the 64Bit Desktop 12.04 system. The network connection works intermittently meaning web sites . The drivers are from Ubuntu, not proprietary. All available updates are installed already. The error is:

"Firefox can't find the server at www.reddit.com."

Suggestions? Thanks.

cat /etc/network/interfaces
auto lo
iface lo inet loopback

I have read other posts about disabling dns resolve to work around this issue. Is the resolver going to be fixed anytime soon? I have a hard time believing that basic IP functionality is broken only in my environment and not everyone is having issues with this. Seems pretty basic but perhaps I am missing something?
