I have a 40/20 BT Infinity connection with a HH5.
Earlier this week I was on a computer wirelessly attached to the above HH5 when I lost internet connection. It would not reconnect as it said my password was wrong. I reconnected by pressing the connect button on top of the HH5. We have now found that all our computers ( 3 laptops with wireless connections and one desktop with a wired connection) have suffered the same problem and the password is still wrong!
Unfortunately one of the laptops which has always had a good connection is now problematic.
