Hello, I have a TP-LINK WPA4220 and it works very well but i improved my internet from 100/100 to 500/500 so i decided to buy the TP-LINK WPA8630P KIT but when i connect to my computer or any devices

Hi I just purchased the Powerline WPA8630 kit with 1 extender. Allows me to hardwire some devices in front room - well away from my router. Works brilliantly for ethernet. Wi-fi is a bit patchier and
