Sky Go on PS4 crashes my router

Hello,

I've been with TalkTalk for nearly a year and had very good Fibre broadband.  I purchased a PS4 in the Black Friday sales and installed the Sky Go app on it.  Unforunately I cannot watch it though as after around 5-10 minutes it kicks all of my devices off the internet and crashes the router.  The router then restarts after about 30 seconds.

A quick look has shown that others have had this problem before but I cannot see the actual solution.  I've tried a number of things already but nothing changes.  Streaming other apps like Netflix and Now are perfectly fine.

Any help would be much appreciated.

Michael
