[nzlug] OMG, whats going on with my Ubuntu?!?

[Sid Bachtiar]

My network kept getting disconnected. When I restart my computer, I
could ping it for a while, then its disconnected from the network
again. May be I accidentally installed or activate some sort of
security modules?? I just upgraded my OS from Ubuntu 5.10 to 6.06 this
morning. I used $sudo update-manager -d. It was all fine under 5.10.

May be there's a new security feature in 6.06 that I'm not aware of.
