BT Infinity complete reset - what Happened?

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.

What happened?

The WPS pin may have been reset hence the need to reassociate.

Has the actual security key for the wireless network actually changed.

One possibility is that another Wi-Fi network has appeared nearby and is causing problems with interference.

The admin password for the hub manager has not changed

The password that connects a wireless computer to the hub has changed & I don't know how to find out what it now is.

The HH5 is located somewhere that I am absolutely confident nobody touched it.

I have found the network security key - it has reset back to the one that was supplied on the HH5 when new - on the card on the back of the HH5

If a HH5a then there are some firmware upgrades relating to G.INP going around, so maybe the password was reset as part of the firmware upgrade.

I presume it is different to the tag/label on the router now, if so should be available in the web interface somewhere.

As I said above - I think we overlapped - the wireless password has reverted to the one printed on the label.

How do I know if it is an HH5a? The card says that it is a BTHub5-WHZT

I think it should tell you at the bottom of the web interface page.

That along with the firmware version and when it was last updated.

You can log onto the HH5 and have a look.
Browse to http://bthomehub.home or http://192.168.1.254/
then select troubleshooting tab
then select the helpdesk tab
which should tell you all about the firmware and line stats

Thank you.
