I have an incredible degree of latency (minutes) when using screen sharing on my wireless network. It works fine going outside the network, or in conecting from outside to one computer set up with port forwarding to 5900.
Internally though, something is creating an issue. Port forwarding shouldn't be a factor on my LAN.
Apple technicians determined that it's not in the system software by connecting via ethernet and getting proper speeds.
Is there something in the firewalls of my E2500 router that needs to be set to open things up internally?
