Linksys Trouble

I purchased the Linksys wireless router and I am currently running 2 computers off it. One is directly connected to it and the other by antenna. I have access to Internet explorer and all of that, but not Aol Instant Messenger. I can only sign on for a few minutes then I am disconnected. I found out a while ago that AIM is not NAT friendly, whatever that means.. but, I tried changing the port number to just a random number and I was able to sign on to AIM for a while on and off.. but never for a long period of time. I have called all sorts of tech supports and they all say its not the wireless router, but it has to be. I don't know anymore.. I'm so sick of this I just need some answers.

 

In order to determine if the wireless link is the trouble, let me ask a question: Does AIM work properly on the PC that is directly connected to your router?

 

At first it didnt work at all on either, then after I changed the Connection preferences on AIM from some port number to just a random number then it started working on and off today. It will stay connected for about 5 minutes at the most at a time, then a box comes up saying i've been disconnected and it's trying to reconnect, then it goes back on. This is happenning on both computers. Just about 20 minutes ago I decided to unplug the router from the modem and just hook up that one computer directly to the modem, and everything worked fine, the AIM worked fine also... so this is what is leading me to believe it is the router itself and not my cable connection or anything else.

 

What model Linksys router are you using? Is there a possibility that there are any session timers invoked? Does the actual internet connection ever drop?

 

It's a Linksys Wireless B broadband router(2.4 ghz). As far as I can tell, there is no session timer. The internet connection never drops. Just AIM and the service I had switched to before (Trillian). Is it possible that it is the router?
