My UMBP is the 2.4 stock model. When I start up my computer, as soon as the desktop loads, and when I go to select the wireless router, it takes a couple of seconds to accept the wireless connection. Also the selection stays highlighted blue until it is set. Also, as soon as my UMBP starts, and open up firefox and start typing, it kind of lags when they keys are registered when pressed. Is this totally normal? Is everyone going through the same thing?
