Hmm, in my experience, TP-link is sh*te. I have only had trouble with
my TP-Link access points. (three of them).

I had a TP-Link access point. It had a "feature" where multicasts
on the main LAN leaked into the VLAN & 2nd SSID. This made it
impossible for me to have IPv6 on my guest WiFi. I have since
replaced it with a Unifi AC-Lite AP, which works properly. The same
issue affected some models of TP-Link switches.
