I have several macs and they cannot see eachother. They can get on the internet and all are connected to the same wireless. I checked my wirless and confirmed that isolation is not enabled and ssid seperation is not enabled however am not sure if there is something else I am missing. I am also having random disconnects with the wireless even though the signal seems to be good. I do not have this problem with the pc however my router is not the apple brand wireless router.
