  1. Cheers you saved me a few days stress phoning sky helplines with this, already annoyed enough that my migration came unannounced before the weekend

  2. Thanks for this. I had to ensure I was on the latest firmware but after that and using your settings I was up and running!

    I did spend 30 minutes with Sky support and their solution was to send me one of their cheapo routers!

    Wish there was a “buy him a beer” button on your site.
