I'm not sure if anyone still gets connectivity issues, but I do on a daily basis.
When my internet connection switches from wifi to 2g or 3g internet, and vice versa, often GV tends to disconnect and not reconnect.
What I have to do to make GV reconnect is disable GV under the "accounts" section... wait several seconds, and then re-enable it.
At this point GV will reconnect most of the time.

In very few cases this does not work either, and the only option is to reboot the device.

Is this normal?
