Default Unknown Devices using my BT homehub

Hi Everyone,
We use a BT Homehub both wired and wirelessly. There is an option to restrict access to devices as required (to limit use by kids etc). When I logged in to restrict my son's laptop there were a couple of devices listed as Unknown-XX-XX-XX-XX-XX-XX where the Xs represent numbers and letters.
Does anyone know what these could be? We can't think of anything it could be and wonder if someone is using it somehow.
The security is WPA and WPA2.
Any suggestions? Would be very grateful for any advice.
Thanks,
Emma

Has anyone in the household got WIFI enabled phones?
If at first you don't succeed, maybe bomb disposal isn't the best career choice.

Your homehub is also a BT Wi-Fi hotspot for other BT users.

Mobile phones would have been my guess although printers could possibly be attached too?

I have an iphone and my other half has an HTC but these are listed seperately. We have had these for a while though and these numbers have never shown up before.

Never seen this before though, would it go on the access control list?

We don't have a wireless printer. The printer we do have has been installed for ages and not shown up.

Had you enabled that option?

Those xx numbers form the MAC address of the network adaptor for the device that has been connected to your hub.

http://en.wikipedia.org/wiki/MAC_address

The MAC address is supposed to be unique, so you could use it determine the identity (manufacturer, model number, serial number) of the *network adaptor* that has been connecting to your hub. The MAC address won't however tell you the make of the computer, nor the identity of the computer user.

Are you sure it isn't the MAC address for a computer or networked device in your ownership, or the ownership of a visitor to your household?

Here's hoping it wasn't the spotty teen from number 23, freeloading your ADSL connection and topping up his kiddy porn stash. You will soon know if the police call with a search warrant.

Check every wireless device in your household: printers, laptops, PCs, blackberries, etc. Note down the MAC address for each of those devices and compare against the MAC address that you've found in your hub's log.

It's called BT Fon, and I believe all homehubs are set up to accept connections. You can switch it off in settings if you want to, but then you're not allowed to use other people's if you need to x

I wondered about something like this but it has been set up for ages and it is only this week that something has appeared.

to find your mac id:

  • In the start menu search, type cmd
  • run cmd
  • type in ipconfig /all or getmac and it should locate both commands and the window will remain open

getmac is easiest to understand tbh

Might just be the first time some one's used it!

I found one the other week, and it was the EDF meter man checking his Facebook page on his laptop in his van

If it's a Windows laptop, the MAC must be shown in the control panel - network devices, or some such..

Alternatively, use the ipconfig tool which you can access from a DOS prompt.

Click Start, then Run, then type cmd.exe in the text box and type ipconfig /all will show you the following.

The "Physical Address" is the MAC address:



To discover the manufacturer of a network interface, you only really need the first six hexadecimal digits of the MAC address.

In the example above, the first six hex digits of the MAC address are 00-10-4B

Those first six digits, hyphenated as three pairs are then feed into this database search engine:

And the results are....

BT Fon / BT Openzone access DOES NOT show up on your HomeHub.

Users are invisible to you and they cannot tell which HomeHub they are connected to.

The unknown devices are probably your own smartphones if you have them, or the devices you know you have got connected, if you haven't named them!

Well I went out to have a look, before I started panicking.

....maybe I should panic more though, based on what withabix says though, because if he/she's right then he guessed my router password!

Any network drives, network printers, AV receivers, Bluray players or any other devices?

Just delete them and see what has disconnected.

Son has given out your Hub password?
