So, I've been using the SlingLink for years in the same location. Everything stopped working. The SlingLink is showing all 4 ports with a solid light on, even with no Ethernet cables are plugged in. When I reboot it, it seems to work ok (network activity light blinks, Slingbox network activates, light for the one Ethernet cable in use goes solid, etc.). This lasts for about 20 seconds before it reverts to the solid 4 lights with no network activity. The front end of the SlingLink blinks with network activity as it should. Tried other outlets, etc. to no avail. Ideas?
