Since installing the new BT Norton Anti-Virus on my Mac, it keeps creating issues whereby the Mac won’t connect to the hub and I have to restart the Mac and the HomeHub a few times before it will recognise the network. Everything is fully up to date it’s just Norton is doing something I can’t figure out. Can you help?
Have a wee look at this video as to whether you need that AV or not.
