I'm having a severe connection problem in Ubuntu 12.04 that renders the OS almost useless. I have a Huawei E352 3G modem. Ubuntu detects it as a mobile broadband connection without any problem. I created a new connection by providing APN. Now after connection it disconnects after a few seconds, and the modem disappears from mobile broadband list. I tried various workarounds but neither worked. I had no problem in Ubuntu 11.10.

In this case, kernel 3.3 has seen some very good power management enhancements that are… >>> More
