Does your wireless (WiFi) network connection glitch / stop / interrupt every two minutes?
If you have a wireless adapter on Linux like the ath9k (Atheros) or others, and you are on Fedora, here is a solution.
The problem is NetworkManager. It scans the network every two (2) minutes. The solution is a patch to prevent network scanning when you are connected. The asshat of a developer has refused to incorporate this patch in the sources despite many requests for it, so I have taken it upon myself to adapt the patch and produce packages for them. The NetworkManager packages for Fedora 15 are available here and the source package is there too.
