Powerline wireless - how does it work?

[nst68]

I want to extend the wireless to a new extension, don’t need serious bandwidth just enough to run an Echo Dot and surfing.

I’ve been looking at these TP-Link TL-WPA8630PKIT

Do the signal go from the base unit by the router through the cables, then is converted to a wireless signal at the other unit?
Does it create a network with its own ssid?
I don’t want the wireless unit to try and finding the existing wireless and boost it, mainly because with the distance and and thickness of the walls.

How reliable are powerline units generally? Need the connection to be v stable,.

The alternative is to use the BT wireless discs to get a wireless signal there.

It works as you’ve said, there’s another wireless access point but it’ll have your SSID as well so your devices switch between the two access points depending on which signal is strongest.

It works because the internet signals come via the power line, it’s not a standard wireless extender.

As above, just think of it as another access point which shares the same SSID and password as your main one (you'll need to change it in the powerline settings).

Reliability wise it depends on the wiring in your home as well. At home my pair was rock solid, but taking it to a student accommodation years back, it had issues keeping up with sync.
