disconnecting internet access

Hi, i am currently in uni halls, i have recently swapped from windows to opensuse, i did not have this problem with windows, but now am with opensuse, the network uses 802.1x authetication, and the network manager connects fine to the uni network, though 15/20mins it looses the connection, i then have to click the network manager, reselect the network connection, it reconnects and is fine for another 15/20mins, whats goin on? how do i stop this? i am on opensuse 11.2 with gnome. i am still fairly new to linux so simpler terms would be appreciated =D

Sounds to me as if you have set an idle-timeout. Check that in YaSTs network settings and set it to ‘0’ (no timeout).

thank you, it hasnt disconnected so far =D. the idle timeout was actually located in YaST > network devices > modem. once again, thanks =D
