Wi-Fi signal stops broadcasting intermittently

[Jdownw]

Hi, 

I am noticing that my Wi-Fi signal appear to stop broadcasting internittently, requiring a router reboot to be able to have any  device join the Wi-Fi network, ethernet connection stays solid and doing an online health check sometimes fires up the Wi-Fi again but this has happened every day for the last few days now.

Any suggestions would be great

@Jdownw if the hub is really stopping transmiting on both bands then that implies an unusual fault call Sky and ask them to swap the unit
