Potential Serious Security Flaw with BT Smarthub 2

The power line adapters have a network name and all devices using that network name will see each other. Change the network name on your power line adapters to something other than the default.

The devices have a management web interface where you can rename the network.

"I'm of the opinion it is when neighbours are on the same phase which is not the norm. Normally houses are fed red, yellow, blue etc along the street so that adjacent houses are not on the same phase "

Prior to moving to our current house, we lived in a semi-detached bungalow built in 1934.

Each pair of bungalows in the row was on the same mains phase, as where every third pair of houses.

OK.  So I have now paired the TP Links manually.  I guess I just plugged them in when I got them so hence they used the defaults and integrated themselves with my neighbour's existing network.  From what I am hearing, we may not be on the same phase but with a capability of 300m we must be "connected" at some point in the electricity network.

After repairing I cannot see my neighbour's network at all.  Which is how it should be.

Without the "competing" between the routers wifi throughput is massively improved.

Although the info on the TP site says the network with my neighbour may come back but we will see....

Thanks to everyone for their input.  Glad this is finally fix and sorry I didn't pick up the earlier discussions of powerline adaptors.

As I said, the manufacturers claimed 300m and we all know what manufacturers claims are like.  Also, as I said, I’ve not used them since the early days.  Back then you could enter the encryption key but it sounds as though the modern one’s pair like Bluetooth.  There must be some way of distinguishing one network from the other though, so try Licquorice’s suggestion.
