Hi, I have a MacBook Pro. I am wondering if my Mac is equipped for the use of 2.4 GHz and 5.0 GHz wireless mode. I want to use the 5.0 GHz mode for my Mac and 2.4 GHz for my other PCs. I have a 2.5 GHz MacBook Pro with 2 GB of RAM. I thik it is the Rev. E model. Can my Mac connect to a 5.0 GHz wireless-n mode?
