Why does iChat video/audio chat don't work since 10.7.3

Yesterday I updated my Mac to Lion 10.7.3.

Now I can't have video/audio chat with my buddies anymore.

Any suggestions what might it be?


All my buddies are on the same jabber server and two days ago it work seamlessly.

Hi,


This is about iChat being cut off at th router due to some sort of Protection feature.


Most likley this is DoS (Denial of Service)

This is threshold based and will have changed from SNow Leopard as iChat can not use HD camera if the computer has one (meaning more pixels per frame and therfore more data being sent.)


The Protection then cuts the one port it thinks is getting too much data.


It may be before you did not reach the Threshold but now you do.


(could be that the Buddy has just got a faster Service).


In iChat > Preferences > Video Section on both computer set the Bandwidth to 500kbps.

This should keep it below the threshold.

Alternativley turn the feature off in the router's set up pages.


The Log (Open the Send to Apple Pop up and see the whole log) may well list that Pings are not being sent

This could be that the call gets cut off before this or that the router is Blocking Pings.


If you need to copy the log and post the first two sections here (that is in fact all of It except the bit below the Line "Binary Images for iChat")

Thanks for the reply.

I thought in the same direction but I haven't changed anything on the routers side. I just updated my system from 10.7.2 to 10.7.3 and left my settings for iChat untouched including the bandwith limit with 100 kbps.

Therefore I can't follow your conclusion with the DoS.


I'll try it again with the lower bandwith preference on the other side.

Hi,


The Minimum Internet Speed for iChat in Video chat is 128kbps

The 100kbps setting is actually too low.


It would seem that either that setting is not actually working and iChat is sending data more efficiently and is now bumping in to the setting or the other end is sending data to you more quickly.
