Hi guys, so i'm totally new to this and not entirely sure I'm in the right forum but if anyone can help I'll be very grateful.  

I have just received the above model number AR-1838 to transfer the tv image from one room to another.  We set this up but it is not working.  We are not getting an image or sound on the other tv.  All seems to be connected correctly with the infa red over our sky remote sensor.  We have mysky.
Our second issue is that when we had it plugged in and it didn't work it did manage to interfer with our broadband and had to be turned off for this to work again.

Any help would be hugely appreciated.
Thanks
