I set up my range extender main unit, plus two extenders when I moved in to a new flat. Got given the standard wonky WiFi password Sky give you, and set up the extenders with that password. Since then I've given my WiFi a normal password, making it easier when guests are over etc, and it has caused nightmares with the extenders. The extenders are on the old password, but the main room is on the new password (eg you're in the main room with router and you have 1 password, but in room 2 or 3 - away from router but with the extenders, you have a different password, but the WiFi network is the same name...) so it causes us to have to change/re-enter new/old password whenever moving room to room - please help!
