Yes, I agree with that, but what about the modem mode in the dongle? The dongle has flash memory, so Isn't it possible for the status within the modem mode to be changed in such a way that the change survives an unplug? I'm still seeing inconsistent behaviour, but some of it suggests that when my dongle switches into modem mode, my system is not always seeing the same condition. It always gives an indication of the mobile service being available, but sometimes it won't connect and sometimes it will connect. How can we explain why an unplug-replug sometimes makes it connect, and sometimes it doesn't?? Today my Ocelot left my dongle in such a condition that when I tried to use it with my Windows Huawei Mobile Connect software, it wouldn't connect there either. No amount of unplugging-replugging or closing and reopening Mobile Connect would persuade it to connect, even though it was al.ways indicating that my mobile provider's service had been detected and was available. Only when I went back on Ocelot and performed a usb-modeswitch command on it did it finally connect again. As you may gather, I'm still stuck in brainstorm mode ! -- You received this bug notification because you are a member of Desktop Packages, which is subscribed to network-manager in Ubuntu. https://bugs.launchpad.net/bugs/868034 Title: Huawei E220 can't connect on Ubuntu 11.10 Status in “linux” package in Ubuntu: Confirmed Status in “network-manager” package in Ubuntu: Confirmed Bug description: I'm using Ubuntu in my HP Pavilion dv6745tx laptop.
