Ok - had issues on TWO different guest networks.
I have a MacBook Pro up to date, the usual Applemail, etc.
1-On one guest network I have no problems internet surfing - BUT I can NOT send, nor receive email! :(
2-On a different guest network, I can not get on at all! All the folks w/Windows based puters can, but I can not.
ANY ideas the problems? Thanks!
