Thank you for posting to the Forums. I can certainly understand how frustrating this can be. When connecting the Slingbox to a router that is connected to another router, you may have to port forward the Slingbox to work with both routers. Most of the time when you switch the router that the Slingbox is connected to, you have to factory reset the Slingbox. However, with being able to connect to the Slingbox on the Android platform, I believe that your issues is that the Slingbox needs to be port forwarded with the new router and then with the original router.
Below I have provided a link to a website that will be able to assist you with port forwarding the Slingbox.
If you have gone through the portforwarding, then please reply with any issues or concerns.
