No probs Kev ..
What you may want to do, if that
Kogan thing persists on your network:
Try to find the mac address filtering feature on the router, and strictly set it to not allow this device on your network.
You're sort of doing your neighbour a favour, in that, once the
Kogan thing is attached to your network(when it actually is attached!), she can't connect it to hers. (you can only connect these devices to one network at a time.
Otherwise: If it's not connected to your network, work out with her that it's connected to hers. Once it's connected to hers, it won't appear on your network(coz of the one network at a time limitation).
Problem is, if her network goes down or is off and your is on, the
Kogan thing will try to connect to your network again .. and so on ~ in perpetuity.
So the best way to stop it connecting to your network(and therefore doing your neighbour a favour) is to ban it from your network(ie. router) with the mac address filtering.
All good for your network security and all .. but the
Kogan thing still connected to it!
And if it's not yours, and the network is password protected, how did this thing connect.
I don't want to worry you or nothing .. but as it's a TV(if it is indeed a TV) and TVs are generally used to watch movies of some type(can of course do other stuff, but movies are their forte!) .. movies do usually require a fair amount of bandwidth if downloading said movies from the net .. so ... err ... I'd be more mindful of it ... and, booting it off the network sooner rather than later.
