Recently upgraded from PlusNet Broadband to PlusNet Fibre. Newer laptops and iPads etc.. all worked okay but had to switch on IPV6 in network setting on older macbook, which now works fine. One remaining problem is I can't get Sky On Demand services as Sky Box not on internet. I have a wired connection to the box which worked fine before. Network Screen on Sky says : Connection to Broadband Router - Fail Connection to On Demand FAIL IP Address 0.0.0.0 DHCP ON Any suggestions to remedy ?
