Msn Disconnections

I don't use MSN all that often but my roommate does. Our current setup in the household is a telus modem connected to a Linksys wireless-G Broadband router with SRX200. I am hard wired to the router but everyone else in my lan runs off the wireless.

My problem is when we are both running msn on the lan at the same time, it crashes every few minutes (10-15 minutes) on both of our systems. (note only msn crashes internet works fine no hiccups). I currently run the newest version of msn live and so does my roommate. I have tried switching versions on both systems but it doesn't seem to fix the problem. I have run a laptop on msn in unison with my computer both hardwired with no problems but if anyone is on my wireless while i am on msn hardwired we disconnect every 10-15 minutes. I have opened all the MSN ports, tried UPNP nothing fixes the issue

Any ideas what my problem could be? i'm quite confused at the issue.
