Hi,
I use a couple of TP-Link RE300 Wifi access points connected to my Zyxel router in order to boost WiFi.
They have been very good, and provide both 2.4GHz and 5GHz when my Zyxel router only has 2.4GHz.
They support WiFi calling and have been good for my family and I to use NOW TV through as well.
I also use some TP-Link AV1000 powerline adapters to help me work from home well, which have been great.
Kind regards,
Tony
