I have a two node W3600 Deco unit ( same as x20) working great since TP-Link provided an update to disable UPNP - thanks However, I get occasional hiccups - slowdowns/disconnect I have over 40...

@Tony Thank you very much I've installed the firmware update and it seems to be functioning

In looking thru the manuals I find that the ability to turn off UPNP is rather inconsistant in the DECO series of Mesh Routers DECO x20 x60 W3600 No UPNP option DECO M4 No UPNP option M5 Yes you can...

There doesnt seem to be a way to disable upnp on the x20 deco. Indeed, this also seems to be true of all the devo routers Am i missing somehing or do i need to find another product if i want this...
