Is it possible to reboot my router remotely
@Wilmslow-Bridge what I have done is connect a mesh system to my hub.
You could do the same by turning off the WiFi on the Sky hub and running a mesh system in Access Point mode (AP). The mesh network would need to be set up to allow remote access.
The screen shot below from my phone was taken while I was in USA. My spouse commented that she could not close her WiFi enabled blinds. I rebooted the network when it was convenient for her.
The Sky hub could be left in place to assign the IP addresses to your devices and a mesh system can deal with the WiFi around your home.
I use a Zyxel DX3301 as my hub/router (£10 courtesy of eBay) and is the "Internet" in the screenshot. It has been very reliable and fast and is just left alone.
