Try as a might, I can't get my PS3 connected to the playstation network with my airport equipped iMac. By using the internet sharing option, the PS3 does detect the signal, but simply won't connect. On its own it can't even get my IP address, and even if I input this manually I then get an error about a problem with the server name. Quite a few people seem to have this problem, but it never seems to get answered properly -- like a similar thread on this site http://forums.macrumors.com/showthread.php?t=264445. It definitely isn't my PS3, as I can easily join the network with my neighbours unprotected wifi. Problem is he doesn't keep his computer on all the time, and asking him to do so might sour relations somewhat! Any help would be very much appreciated. Thanks!
