Add a WAP to my home network
I want to add a WAP to my network to cover the 2 back rooms in the house - there's a thick wall between them and the router.
We have a smart TV/Freeview box and several wireless devices there, and have used Powerline wifi/ethernet extender TL-WPA4220 as a solution for a while. Speeds are fine, but the extender drops the connection frequently. I've replaced it but his make no difference. Our wiring isn't great.
My question is can I replace this extender with a WAP with my current router, and if I can, which WAP? If not, what wold you suggest?
