A month or two ago I installed Ubuntu Netbook Remix to my Eee PC 900, and during the past few weeks I have been using a 3G modem dongle with it. Last night I updated the packages in my system with the Update Manager, and after rebooting the computer the modem won't work.

Under Files and Folders, there's a cd icon named after the modem, so obviously it's not totally invisible to the OS. However there's no option in the drop-down of the network connection systray icon. Therefore my suspicion is that the error is in the software that manages network connections. Can I see a list of which packages were updated that last time, in order to narrow down the troubleshooting?
