I have a brand new 15" 2.53 gHz MacBook Pro. I am currently on vacation, and the house that we rented has wireless internet. I tried to connect to the network and every time I try to connect, It keeps giving me a "connection timeout" error. This is an unsecured network, on which every other device we have with us (an iPhone, an ipod Touch, and a Windows laptop) can all connect to without a hitch. Two days ago we were staying at a hotel, and the MacBook Pro could connect fine with their network, and it was working fine at home until I left. I ran a software update on the MacBook before we left, so it's up to date. What's really strange is when I went to the diagnostic in the network preferences, it said that the network here required a password, which, like I said earlier, it does not. Any help will be greatly appreciated.
