Hi, we've problems with a Novatel based Mobile Broadband card. The serial device doesn't respond to AT Commands after it has been initialized and a successfully registration to an apn. The modem-manager falls back in an endless loop after that behavior. Bus 004 Device 002: ID 413c:8137 Dell Computer Corp. Wireless 5520 Voda L Mobile Broadband (3G HSDPA) Minicard Status Port The logfile is attached. Before we used network manager, we had a very simply umts solution, which only uses a few AT commands. This did work for quite a long time. It seems that the firmware crashes on some of the AT command (coldstart is necessary, to get the card working again). Any ideas? Gerald
