Constant severe WiFi speed drops

[DSkyUser]

For a few months now I sm getting constant, sudden speed drops on WiFi devices, dropping from 6-700mbps down to sub 1mb speeds, lasting anywhere from 2-10+ minutes. 

this impacts all devices on WiFi at least, possibly Ethernet but can't say I've noticed it on those. 

I have tested multiple WiFi channels, router is in an open, high space away from devices and I have tested with just two mobile phones connected and nothing else, and the issues still occur. 

as the borsdband checker reports no issues, I seem to just be told I need to change WiFi channel or reboot the router to fix it, obviously those haven't worked. 

is anyone else experiencing this of late? Prior to this I never had issues like this.
