So, I have just bought the VR600 to replace my Sky Q router, due to internet problems that Sky refused to admit are theirs.  I have setup the device and got my laptop back onto the internet, and also managed, somehow, to get my Sky Q TV box connected, so now I have all catch up and on demand again.  The problem I am having is other devices in my house will not connect to the VR600.

Mobiles say there is no internet connection;

Roku will not connect at all;

Ipad will not connect - says no internet

Smart light bulbs will not connect due to the mobiles not connecting.

Any help will be greatly appreciated
