Broadband Wifi/Ethernet Powerline extender compatibility

[JohnB54]

I'd be very grateful for some advice regarding my home network. I currently have a BT Mini Connector kit (two units, plug-through) providing ethernet connections for my TV and PC. I want to extend the ethernet and add at least one wifi booster. I have a couple of TP-Link Powerline plugs (one ethernet, one wifi/ethernet) which appeared to be compatible (according to what I've read online), but they don't seem to want to talk to the  BT Mini Connectors. As I'm no techie, I plan to simply buy some more BT-branded connectors, but was wondering if I might encounter similar problems with different models? My mini connectors were bought in 2017 and I'm thinking of buying a pair of Flex 1000 adaptors and a WiFi Extender 750.

You cannot have two different systems running on your electric ring mains

Thanks. I can understand the TP Link plugs not working, but will the (newer) BT  extenders not be compatible?

BT branded devices (e.g. BT Mini Wi-Fi Home Hotspot 600 Multi Kit) support expansion of the powerline network by adding extra devices.

The instructions for doing so are in the user manual and are very simple; namely hold down a button on the nodes you're adding for about 8 seconds followed a few seconds later by holding down the same button again for about 1 second on both the existing nodes and the node you want to add.

@JohnB54  You can only extend powerline networks by adding extra 'slave' devices, you cannot connect another 'master' to the router.

Thanks. The BT Mini Connectors are both the same - no slave or master (although obviously the one connected to the router is automatically the master). The question is, can I add other BT models as slave units?

Yes. Check out the user guide which is available from the link in my last post
