Thanks for responding, however the command line you suggest doesn't show the channel or signal strength: (and now the keyboard doesn't work at home either, the mouse is fine).
this is what I see at home.
SSID 1 : <my network name>
network type : infrastructure
authentication : wpa2-personal
encryption: CCMP
MY R7000 is broadcasting on the 2.4GHz and 5GHz bands, but according to the Netgear admin screen my Surface is connected on 5GHz
I left the keyboard on charge overnight, just in case it was flat,
Given the mouse and surface pen are both functional, its beginning to look like a faulty keyboard.
I'll have a go on Tuesday connecting it to my company iPhone <hawk, spit>
