My problem is the wifi internet is not stable and regularly goes out for 4-5 seconds, although the network stays up. However it is annoying because my macbook does not automatically reconnect, and instead sits there saying nothing is connected when it detects a network doesn't share internet anymore.

By regularly I mean 7-8 times per hour I have to manually rechoose the network. On windows 7 the computer stays connected, and I just have to wait while hitting refresh for the signal to come back. I would like to be able to have it stay connected but without a signal like what happens when I am in bootcamp.
