3G connection is not working after the Ubuntu 11.10 upgrade (and after the first Network manager update of 11.10)
During the Natty times I had a fantastic 3G connection, fast and ready! Once I upgraded (via update manager) to 11.10 I noticed that it was not as good as Natty, slower and more failed trials to log in (I sometimes had to restart the computer).
The other day, a Network manager update appeared in the software updates, and I was too exited for it, thought this will solve the "some what" issues of Ubuntu 11.10, but what I got, was a terrible Wifi connection and even worse 3G connection, to be more specific from that time on I could never connect to the 3G connection again.
