SOLVED weird wireless network that shows up as WIN_43f7 can't figure out where it is

[BirdDad]

I have checked all my equipment including repeaters and I can't find where this thing is plugged in or transmitting at. It is encrypted. I do know that it is stronger at one side of the house than the other but I can't seem to find it.
Does anyone know what it could be?
Thanks
It was the modem my ISP gave me it was still plugged in. I am using a modem not from my ISP.

Probaly someone around your neighborhood who have a Wireless AP with SSID WIN_43f7.

Or one of your Smart phone Tablet etc. transmits this. You can use this free portable App on Win 7 computer to get more info about this SSID.

I live in a rural part and the signal is undetectable from the other end of my house, whatever it is, it is coming from my house, none of the tablets are on. Thanks for the tool advise, I will give it a shot.
