My office laptop ( which is an HP plugged into the same wireless network at my home, runs XP ) did not disconnect the entire night. My personal laptop ( which runs SXDE ) had around 50+ disconnections over a period of 12 hours. And Ubuntu, which runs on the same laptop on the same wireless network, never disconnects as well. It could either be - the driver wpi0 - flaky nwam ( which i think is the culprit ) > > Cheers, > Sanjeev. > > > Manish Chakravarty wrote: > > Hi BOSUG, > > > > I have been working almost 12 hours straight on my SXDE desktop. > > I am using the default GNOME desktop to do KDE4 builds :) > > > > The machine has serious issues, and it has had an uptime of just 12 > hours. > > > > 1) nwam/wireless reliablility > > > > nwam brings wpi0 ( my wireless interface ) down and up whenever it > > wants to.
