Has anyone be experiencing problems with USB mobile broadband Dongles on OpenSuse 11.3? Once the device (Huawei E156) is inserted OpenSuse recognises it automatically but after a few minutes it drops the connection and the device is not able to connect again.
The Network Manager drops the device from the list and then re-inserts it, but for some reason it disables the Mobile Broadband. Removing and re-inserting the device dos not resolve the issue. I used this device very often on OpenSuse 11.2 without any problem.
Is anyone having a a similar problem? Does anyone have the solution?
