Hi,

I've been experiencing problems with the 3G Internet lately. What's happening:

1. If I connect to 2.5G network (I'm virtually never connected to the plain 2G network) everything works fine. It's slow but works
2. I switch to the 3G/3.5G network by the status menu applet
3. and connect to mobile Internet, then I'm first connected to the 3G network, then to the 3.5G network. I'm in the 3.5G network with a good signal. Everything works fine
4. After a while (< 1 min) I'm switched back to the 3G network. And from then, mobile Internet fails to work. `ping 208.67.222.222` has 100% packet loss although it used to have 100% received a while back. Reconnecting fixes temporarily (points 3 and 4 once again)

What might be the cause and how can it be fixed?
