my TRB140 only works if I set up the service mode to "3g only". If "Auto" or "4g only" is selected the device connects to the mobile network but no data (e.g. ping) will be transferred. The modem status is shown as connected and I get a mobile IP Address but I have no access to the internet. With 3g only mode eveything works fine.
I have the latest firmware installed (TRB1_R_00.02.04.3). My mobile provider is Telekom Germany.
Does anyone have the same issue? What can I do?
