Thanks for using our Answers forum. I understand that you are having trouble getting your Slingbox to work with your new Sky router. Slingmedia can absolutely help you with this. I am located in the US and I have found that that router is in the UK. I have a customer support phone number for the UK. That number is (020)7294 0157. Please feel free to contact Slingmedia at that number.
Hope this helps.
