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.

Regression 9.04: 3g modem problems
https://bugs.launchpad.net/bugs/3
Public bug reported:
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
