I have quite similar simptoms here, with minor differences, with the Huawei E272 (which I heard about as a fast E220).
First a minor issue, if the modem is connected during bootup, it is not recognised. So I disconnect it during bootup, and plug it in later. Than... The first connection to the network works perfectly. However, either I lose connection or disconnect manually, I am unable to reconnect any more. There seems to be high CPU usage during the connection attempt. I attach the tail of the syslog, which repeats a simple pattern of messages until I cancel the connection request. The only way to connect again to the network is to reboot my computer - first plugging out the Huawei, than rebooting, than plugging in the Huawei again, and than the connect may succeed. Any other method I tried fails. ** Attachment added: "Tail of the syslog during a failing connection attempt" http://launchpadlibrarian.net/35931423/HuaweiNetworkErrorOnSecondConnectionAttempt.txt -- [karmic] Network-manager fails to reconnect to 3G network https://bugs.launchpad.net/bugs/438150 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
