Synergy drops

One thing I have noticed running Synergy with the server on Os X, and the client on Vista, is that if unplug the AC on the Vista side, and start to use on batteries, it starts to drop the connection, pretty, pretty often.
It doesn't matter how much battery left it has, the drops begins as soon as I unplug the AC.

I'm not sure, but I doubt that this is a Windows problem, I mean, the Compaq's WiFi NIC does work pretty well, with a very good signal strength all around, pretty much all the time.
