Hi, I'm running Ubuntu both straight from my HD as well as as a guest with a Windows 7 host. The office router just got restarted (they didnt change any settings) and since then my network has been acting up.

Basically I have a connection for a couple of seconds, then it stops working (just stops, the connection is still "active"). When I run a ping it just hangs after a while.. then after like 30 seconds continues.

It does this both as a VM guest as well as a direct install on the HD.

Any ideas what may be causing this? I'm practically unable to use Ubuntu right now
