No zilch about these things hence what is probably a daft question. Bought a couple of these off EBay which although connected both ends to extensions work very well. Can I now add a third as I need the internet in another bedroom for a smart TV. Or do I need to buy a set of three so they come ready paired?
There's usually a little utility you can download in order to configure any additional devices to pair them up. You might specifically have to ask the Ebay seller about that process on these prior to purchase, however it's usually something you can do yourself. I'm using TP-Link AV600 plugs (these https://www.amazon.co.uk/TL-PA4016PKIT-V1-20-Passthrough-Configuration-UK/dp/B016ZZAVYI) although I have two sets of the nano and two of the passthrough for four plugs total. These come ready to work and don't require pairing, they have an optional encryption key that I'm not using presently.
Just buy another and it will work, it is worth using the encryption as you can be joined with your nextdoor neighbour if they are unsecured and they are using unsecured powerline as I found out a couple of years back. The utility is useful for configuring sleep modes (or in my case disabling as it was 50/50 if it would wake back up)
I had issues adding a couple to my original pair ( adding in 600 units to the 500's, TP Link), but after a bit of shifting them around got them to recognise each other. I ended up putting the 600's on the router and PC, with the 500's on the TV's. Once sorted though, it doesn't matter if you cut the power completely, they seem to recognise each other straight away. Just to let you know that if they don't connect first time, or second time...
In my experience you can just plug new ones in and they should find the network irrespective of brand or rating. You may need to sync the new ones and to do that you simply press the little sync button on the main one (the one directly connected to your router) and within 30 seconds press the sync button on the new one you're trying to connect. Do bear in mind your Powerline network will run at the speed of the slowest device connected to it so if you have AV600, AV500 and AV200 all connected then ALL of them will be running at AV200 speed.
We've got 6 and a variety of D-Link and TP-Link adapters (4 different models including single & dual port variants and one triple port with wifi repeater). Apart from the wifi enabled one, all have been added to the network just by plugging in and turning on.
