I have fibre broadband and a bt hub 6 router. When searching for Wi-Fi it comes up with the name of my hub 6 router as shown on the back off my hub, and then another available Wi-Fi network with the exact same name except from an added number on the end? Anyone know what this might be? I've had this hub and broadband for 3 years now at the same address and this has never shown up before. Thank you.
