Hi guys, Last week I purchased a MacBook Pro 17''. Wonderful computer indeed, however, I am having problems with my Wi-Fi. My Wi-Fi was working like a charm last week until today. I bought this computer in Orlando if it matters, used it in my hotel there, and now I am in Miami, using it and connecting to a wireless network in another hotel. I am not sure if it matters because in both places my Wi-Fi has worked wonderfully, until today. It just stopped working altogether. I'm sure the hardware itself works, because it can still deliver the plethora of networks available in my hotel and I can attempt to connect to them. When I try to connect to one of them, the Wi-Fi has an animation, then it shows full bars, then one second after it shows me the Wi-Fi icon with an exclamation (!) symbol. My hotel provides different networks called "SpeedLinkX" (where "X" is a random number). I can't connect to any of them right now, although I could yesterday and the day before. I have googled for a couple of hours now with no luck. The change location trick didn't work for me. What else can I try? Like I said, it randomly stopped working, I haven't touched anything in my settings that could possibly kill my working setting out of nowhere, and when I connect with my iPod Touch, it works like a charm. Oh, also, I am pretty new to Macs, so I will need instructions you would give to a "Dummy" for me to fix my issue. I feel shame for asking this since I am a computer geek and even a programmer but I have never used a Mac before haha. EDIT: I have noticed sometimes it says that the connection timed out. EDIT 2: Forgot an important detail. This hotel's connections are note encrypted, so it doesn't prompt for a WPA or WEP key, but it has one of those "Login" pages where you need to get the info from the provider.
