I have a rather old (2015) vintage pair of Powerline adapters (model is TL-PA451KIT AV500)
I need to improve the wifi coverage in an upstairs room in the house and thought I might be able to add another adapter to the existing pair. I'd like an adapter that plugs into the mains, links to my router via Powerline and transmits a stronger signal in the room.
I've been looking at two models
TL-WPA8630P - has dual band wifi, might be faster (not sure) but £85
TL-WPA4220 Powerline 600 Wi-Fi Powerline Extender - only single band wifi, probably slower, but only £31 instead
I'm inclined to go for the less expensive model (the TL-WPA4220), but am I missing some important consideration here in terms of compatibility with my existing setup?
Grateful for any advice
