Hey, I just got my new PB, I charged it up for 5.5hrs and attemped to use the wireless. Nope, it recognises the network but when I go into Safari it says that what ever website I'm trying to go to cannot be found. I have a Linksys Wireless B router that requires MAC codes to be entered in to provide Wi-Fi access. I put in my PBs MAC code before and it still will not work. Whats the Problem?
