Network number 9!!

I have installed a TP Link ac wireless dongle (see other post) on an oldish laptop (strongly recommended, by the way). I'm told that this is wireless network number 9 and I've forgotten how to see and get rid of the other 8. I've had various dongles and bits in the past, but certainly not 8!!! Presumably the inbuilt card is number 1. I'm using Win7 Home Premium on the laptop.

Right click the start button, choose Network Connections.
