I had to replace my router with an Ativa 54g wireless router...made by Belkin.  I can connect to the internet and go to web pages just fine but when I use Messenger live and someone sends me a message, I can get one or two then it stoppes receiving.  Sometimes, if I wait, then I'll get 4 or 5 in a row as if the person I'm talking to responds to my message and their messages end up in a queue and then get sent at once.  I've tried resetting the router and modem to no avail.  I've called Belkin and their tech support is in the far east somewhere and are barely understandable.  Worse yet, they are rude and impatient.  Any help would be appreciated.  I assume that the problem is with the router settings as it does the same thing on Yahoo messenger.

Thanks
