Powerline WiFi

They drop off and re-connect. This is why it is best to use discrete SSIDs. If a phone hangs on to a weak WiFi signal, you can force a change to a stronger signal if it has a different SSID but you can't if it has the same SSID.

Just to make sure you are setting this up correctly.  Using a TP-Link powerline to WiFi setup, you'll have the plain powerline connection connected to the router (SH2) using an ethernet cable.  Then you place the WiFi extender elsewhere within your property - ideally on the same ring-main.

Now for the tricky part.  Historically I've sucessfully setup I think it was the 7510 device using the same SSID and password as the main WiFi.  But you can get issues because there are effectively two routes the combo node can use to send data back to the router through - the powerline AND the WiFi which even spanning-tree protocols can struggle with.

As for other extenders and device properly re-locating from node to node.  You either need devices that actively and aggressively hunt the best node, or a router than can actively manage its satellite WiFi Mesh devices - these exist but are less common than you'd think!

Completely wrong, you are thinking about WiFi extenders rather than WiFi capable powerline adapters with regard to SSID and password.

Through the magic of circle to search ✨️ I now understand what that means

Thank you , yes they are set up properly.  I have done the same setup on another BT hub 3 and get the same issue.  "Unable to connect" popup on my phone when the extender uses the BT SSID, but not the TP link SSID.   I have read the hub is locked to BT disks if you use the BT SSID. Makes sense from a BT sales and repair point of view.

The only 'locking' is the BT complete WiFi black discs that will only work with the SH2.

I tried 2 different  powerline products on HUB 2, both accepted the the HUB wifi clone and connected to the internet

On the HUB 3 both products accepted the wifi clone but would not connect to the internet (pop up warning)

HUB 2 is open , HUB 3 is locked to proprietary disks.

Just to clarify, for the HUB 3 the SSID is locked to BT disks only,  if you use the SSID that comes with the Powerline adapters the internet works fine.  If you link multiple Tp_link WIFI adapters they will auto clone the 1st  SSID so that's a cool feature.

[licquorice]

No it isn't, the BT hub is not 'locked' to anything. I have 3 TP Link powerline adapters that work just fine with the hub. 

What exact device do you have? I'm still not sure if you have powerline adapters or a standalone extender, they are entirely different things.

Powerline adapters,  TP-Link TL-WPA4220T wifi kit (2 units) and AV600 Wifi kit (3 units).  The 3rd unit auto cloned SSID and password from the 2nd unit.
