MSN Error 80048820

Hooookay.

Everytime I try to sign into msn for the past week, I get this error message:

___________________________________________________________________________

We were unable to sign you into Windows Live Messenger at this time. Please try again later.

Error code: 80048820
Extended error code: 8004840f

All I know is, it's because of my router. Whenever I have my internetz plugged straight into my comp (without the router), the msn works. But there are other people in the house that are going wireless and need it in the router, so I can't have it plugged into my comp.

So with all that crap writen, all I know is that it's my router that's causing this issue and I hope someone knows what to do.

THANKS!!
