I recently got a 770 on WOOT and love it.
This thread has been very helpful, but my problem seems the opposite of most of the posts.
I have no problem at all with public wi-fi. At home on my Mac Mini I cannot get online via Airport. I would like to do this to load software, etc.

I have no problem getting a "local IP" connection which seems to be useless.
I tried the suggestion of manually typing in an IP and DNS address. Again, I get a connection but opening a browser gives a network error.
Two issues may be relevant. 1-My mouse and keyboard are wireless so I cannot turn off bluetooth. 2- My DSL connection is shared via a d-link hub.

I wonder if I am not using the correct IP and DNS info.
Any suggestions on things I can check? I have tried most of the channel choices in Airport setup, as well as auto.
I"m unix illiterate but I can follow directions. :-/
