Consistent 'Connection timeout' only on one machine
I run a B&B, so i have guests very frequently, and none have reported problems with the network/Internet. My iphone & ipad connect to the network/Internet with no problems. My Mac Pro connects half the time to the network, but won't connect to Internet or print wireless, and the other half i get a 'Connection timeout' kickback. Airport Utility is unable to locate the Airport Express, even when i do join successfully.
. I took the MP to an apple store, and it connected to a network / internet with no problems.
. any other machine/device can connect to the Airport Express no problem.
. ive reset all caches, including kernel.
. I've booted into an external 10.6 and i get the same results.
. I've factory reset the airport express 2x.
. I power cycled the cable modem.
Sorry for such a long post... At this point im completely lost, and as a result im typing all this on my ipad : )
