Regression 9.04: 3g modem problems

[Peter.Kostin]

in Ubuntu 8.10 my 3g modem (Nokia N82) was working correctly, but after update to 9.10 NM connects, but no pages can be open. Though smartphone shows that connection is on. And yes I can use internet (Opera mini) in Nokia without problems, that`s mean that errors are in Ubuntu.

The same problem - http://ubuntuforums.org/showthread.php?p=7141105#post7141105

This is my syslog:

Please Help! Let`s prove that Ubuntu Community is the best!

The problem was with settings in NetworkManager after upgrade they changed from Auto PPP to Auto PPP (addresses only). Developers of ubuntu must be more accurate, because of this small error I was going to migrate to windows.
