internet connection ?

Is it possible that the neighborhood signal you are picking up may be part of the problem? For ex you connect to G's router. G then does something to their router connects or drops connection,plugs it in, raises the security, has some device interfering with signal,has 2 or more machines in net at once, has a wireless phone that conflicts with the wireless computer network all those things can have a negative effect on the signal available to you to grab from G. Phones and other computers in your own home can do that too so can other interferences sometimes even a garage door in your neighborhood tho the old garage door thing is hopefully very rare these days. Also you may not be the only one in your neighborhood tapping (ie looking for a signal other than from a service to which you subscribe and someone else may tap in and preempt you if they are closer to the signal or have stronger reception. Try it for a day or two with just your own signal and see if it behaves any better. Of course another tapper nay be tapping into your home signal too unless it is security protected.

Did you have this problem before Vista?
