I have a 2wire 2700HG wireless modem.  It has a PC, Xbox and Slinglink connected to it.  Before I connected the Slingbox, the Xbox Live worked with not connection issues.  Now that I connect the Slinglink, the Xbox is always getting disconnected or does not connect at all.

I set up the port forwarding for the Slingbox but it did not solve the issue.  Any help would be greatly appreciated!  Thanks.
