Shrijit - This bug thread was opened specifically to talk about about the problems that have appeared with the Huawei E220 on Ubuntu 11.10 that were not there on Ubuntu 11.04. It does appear from what some posters here say, that 11.10 is also causing the same or similar bugs to show up on other modems. The same fixes don't always apply across different modems though, and it's not safe to assume the fixes are universal. Some work, some don't, but it's worth giving them a try.
I still remain puzzled about that blacklist.conf fix because I'm pretty sure the tests I did with it yesterday proved that it was working OK, and yet today it's not working at all. Still interested to hear the experience of others on it. -- 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 “network-manager” package in Ubuntu: Confirmed Status in “usb-modeswitch-data” package in Ubuntu: Confirmed Bug description: I'm using Ubuntu in my HP Pavilion dv6745tx laptop.
