User cancelled request error

Question

Have a feeling this has been discussed before, but couldn't find anything that worked. When I try to start a video chat with a friend, I get the message that the user cancelled the request, even thought it was accepted. Both of us were able to successfully connect to the apple test video chat. We have port forwarded all the ports Apple reccommended, but still no luck. Anyone have any suggestions?
My setup: 12inch ibook G4 with 768 megs of RAM
Router setup is tricky: Linksys WIRED router connected to cable modem. From there I have a Netgear WIRELESS router plugged into the Linksys. My ibook uses wireless most of the time.
I can get video chat no problem when I connect directly to the modem. Couldn't connect with just one router on the network (either one). The wired linksys is older, so I thought it may have been that, but the newer wireless router didn't work either.
Anyone know what the specific router settings are supposed to be? I have applecare for the ibook and they said they couldn't help since it was a router issue. I thought good customer service would be helping the customer get their product working, but apparently not. Any help is appreciated!

  Hello Meghan. First, I suggest you and your chat buddies who use Tiger should consider the suggestions from Help for iChat AV 3 Problems that are relevant to your system(s?) to see if they resolve your problem.
If they do not, both of you should test with several other users to find which system is causing the problem. Otherwise, both of you will need to troubleshoot everything.
If you need more Buddy Names for iChat Test, you can get some here. I keep no regular hours, but I (or the others listed there) will be happy to test with you whenever our status shows green ("Available") in your Buddy List.
The problem system should then consider the suggestions in Using iSight with iChat AV.
Among the suggestions there are tips on trouble shooting multiple devices as well as links to info about router configuration. Having tested with only one router in the loop, you have a good start on that, but you may need the additional suggestions, too.
(You do not specifically say so, but I assume here that you are using iChat AV as your video chat app.) Use of multiple routers with iChat AV may require additional configuration settings. iChat AV can deal with only ONE device acting as a DHCP server. Therefore, I suggest that you only use one router if you can operate in that way.
If you MUST use two routers for some reason, DHCP serving MUST be disabled (turned off) on one of the routers so only ONE of them is serving DHCP. The best way to do this is to enable "bridge mode" in one router. The instructions for doing this are in your router's users manual.
If you are using multiple routers because you have several computers, game boxes, VOIP devices, etc., connected to your internet service, you should Check your Broadband Speed.
Just FYI, I (and many other users) need NO port configuration of any kind to make iChat Video work. I have my Mac OS X software firewall enabled at all times and use a wireless router that is in current production. I make NO manual port configuration settings in either component.
If you must make manual port configuration setting to make your system work, pay particular attention to the router suggestions from Ralph Johns that are linked in "Using iSight with iChat AV." Ralph also explains the error in Apple's Technical Article #93208. Carefully double check all settings and changes that you have made against Ralph's info. That should get you going if your problem is related to port configuration.
