This has nothing to do with filmmaking, but instead with a Linux issue I had on my Netbook, running Ubuntu Linux 10.10 (Maverick) with LXDE and OpenBox, although I was having the same issue even if I booted into Gnome.
In essence, the problem occurs after I put the Netbook to sleep. Basically, after re-waking it, the network would continually connect, then disconnect. The connection lasted only a few seconds, and it would keep disconnecting indefinitely.
After a lot of research, and while running the top program, I found that I was having a conflict between nm-applet and wicd — I somehow ended up with both of them installed while trying to optimize for battery life.
Issuing “sudo killall wicd” did the trick, and I was able to shut the lid, wait and re-open and the network came back on without any further issues.
So, make sure you only use the nm-applet, OR wicd tools.
I hope this will be helpful to someone out there 🙂
