System : up-to-date karmic with NetworkManager PPA
My 3G mobile broadband works great the first time I try to connect with it : the ping is correct and 2 DNS servers ar filled in resolv.conf by NetworkManager.
The second time, the ping is a little bit slower (I don't stop the ping command so it still have the IP address to ping) but resolv.conf is not filled so new DNS resolution are impossible.
I noticed that restarting the NetworkManager service allows to reconnect normaly (neither killing modemmanager nor unpluging/repluging the usb modem helped).
Binary package hint: network-manager
