Hi all,
after last update this morning, i'm unable to connect to internet with HUAWEI E173s.
Before update all was Ok.
Now when i connect to internet my pc says:
Registered on your GSM provider network but after that it says:
your connection has been disconnected.
i'm using NetworkManager 0.9.6.4.
the same key on another computer, still not updated, works well

I tried update the other computer and now internet key doesn't work anymore

Update:
I downgraded modemmanager to previous version 0.5 insted of 0.6 and after a reboot internet key works again
