iChat and the Firewall

I have had my provider open all of our ports relating to iChat and still cannot connect any audio, video or the new screen sharing connections. We are using a wireless T1 service. Could that be a problem? I am lost. Anyone have any suggestions?

BTW - Workstations do not have any firewall settings turned on.

Thanks

Hi

First have you set the Quicktime streaming setting, goto sys prefs/quicktime/streaming/streaming speed, set to 1.5mbps(dont use automatic)

In ichats prefs click on video and change bandwidth limit to NONE.

Restart iChat.

Hi Chad,

Explain "Wirelss" ?

Do you mean like a modem for joining a Cell phone network ?
Or a Dish to a point down the street sort of thing ?

If so do downloads start slow and get faster ?

We connect to the internet with an antenna on our roof that connects to a tower. We get 5mb throughput and its quite reliable and consistent.

Ok,

With these and Satellite connections sometimes the modems have a built in latency.

This means when you download or upload something the speed starts off slowly and builds.

For Speed testing purposes this may show the correct max speed you can get.

However for iChat it may reach the max speed too slowly.

Do you notice that when you download the speed gets faster ?
