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 clients

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 feat
