I would try simplifing things by connecting the Slingbox directly to your router. This will provide a process of elimination to determine if the SlingLink might somehow be interferring with the connectivity. Also, try performing a factory reset as described in this article (http://support.slingmedia.com/get/KB-1000038.html). It is possible that the the Slingbox is using an IP address that is not compatible with your network. Perhaps it was configured to be used with a different router. Reseting the Slingbox to the factory condition will allow it to grab a brand new DHCP address from your router.
