Wifi Interference

[Fk88]

My Sky broadband router has recently stopped working when certain home appliances are operating. I have home walking machine, & kitchen blender, when the motor starts in these devices my router wifi signal stops & router shows error lights. I have attempted the following fixes, moved appliances & router further away and to other sides of the house. I have changed mains power circuits that the appliances & routers are being supplied from. I have changed router wifi channel signals through the admin menus. None of these changes have worked and the problem is persisteing. 

Any Ideas for a fix, would a different router work?

@Fk88 WiFi interference would not cause any change to the leds on the hub but devices would lose connection instead.

If the hub is losing connection one possibility assuming you do not have a full fibre connection is interference causing issues with the VDSL or G.Fast signals used over the copper wires. If the mains cabling runs near the phone cable and the phone wiring in your home is old that maybe tge cause. It could be worth talking to Sky to get a filtered master phone socket fitted as that isolates any old wiring in your home so it can no longer act as an aerial. If you already have such a mastercsocket I cant see what else could be done.
