I am totally confused as to why my brand new mac book won't connect to our wireless network at work. I have spent HOURS on the phone with mac and my isp. No result. I have tried changing the encryption type, putting a dollar sign in front of the key, and even took the encryption completely off. Still, it doesn't connect. But, the network is listed under the airport icon, so airport recognizes it. The isp says the router is mac compatible. firmware is up to date. right now i have our network set on WPA. It connects fine at home. Any ideas? I am desperate.
