Hi all, I've had so many issues with my TL-WA850RA and I wonder if anyone else can help, or recommend a better device?

I have reset this thing so many times that I could configure it in my sleep now. I've update the firmware to the latest version, changed the SSID, reset everything and started again and every time it seems to work OK for a while and next time I turn it off and back on again it says it's connected, the the WiFi connection drops out frequently, sometimes it reconnects, most of the time it doesn't and I have to go turn it off and back on again, possibly pair it again with WPS, or plug it in to my laptop and reconfigure it with my browser.

Am I banging my head against the wall here?

I am open to buying a newer/better device. I have a mix of 802.11n and 802.11ax WiFi-6 devices and an Archer AX50 router. I am just after extending my WiFi to the back of the house because it's a bit patchy.

Suggestions?
