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.

Do you have file sharing set up?  I don't think they will not see each other through the router without setting this and maybe other things up.

Also make sure that the firewalls are off or if on, make sure you're not in stealth mode.

Also, it helps if all the Macs are in the same workgroup. Not sure this is a requirement, but having them agree helps. You can check this in System Pref/Network/your ethernet connection/advanced and then DNS and WINS. In these spots you can enter in workgroup name and search domains (workgroup name).

For example, you might have a workgroup name of home or office and if it's in the DNS search domain listing as well as the WINS listing connecting between Macs just seems to work better.

Go to the firewall under security system preferences. Assuming that it's on, click on the Advanced button.  If it's grayed out, click on the lock and enter admin creds. There's a check box there for stealth mode.

Make sure File Sharing is on: System Preferences > Sharing > chech File Sharing
If you are having WiFi issues, delete the com.apple.airport.preferences.plist from /Library/Preferences/SystemConfiguration/ and reboot the Macs, this will rebuild a new plist file.

To follow up: if deleting the above plist did not solve the issue, move the entire SystemConfiguration folder to your desktop and reboot. Once this folder is rebuilt throw it in the trash.
