Oh, man. We just moved into Cupertino and I can't believe how bad our signals are in this area - an area dominated by some of the biggest tech companies in the world. I'm told it's the building we live in, but the signal isn't even good out on the street. There are areas of Cupertino where there is simply no signal. I've also been told that the city won't let them add any more towers. If that's indeed the case, I think they need to start giving out the network extenders, even though I'm not 100% that will fix our problems.
Please report back if you receive any satisfaction, as I'm in the same boat and would like a resolution.
