Just moved into a small apartment/flat: living room, hallway with office and bedroom etc opening off it . KCOM router with Deco plugged in, one in the hallway and one in bedroom at end of hallway. This gives me a better signal/speed in the far bedroom but office halfway down the hall is a dead spot . I have sky q running off the wifi router and was told to turn off the wifi in the KCOM router . Not sure how to do this or whether it will help or just stop the sky mini box workin? . Any advice would be really appreciated 

Thanks
