I think you're missing the point.
@dabears seems to indicate he was able to connect a WPS client to the node, despite the feature being disabled at the router. That sounds pretty active to me.
The WiFi app I use to scan area WiFis shows what security is actively being used on a given node/client. In the past, pre-Asus routers (and certainly pre-AiMesh), when I've disabled WPS, the [WPS] disappears from my signal in the WiFi app, indicating it is disabled completely.
That is not the case here.
What I don't think you're quite understanding is that the behavior of the app previously is to
not display WPS on a signal if it is disabled. The fact that the node still shows WPS as active on the node for 2.4 GHz, combined with the fact that
@dabears indicates
he was able to connect to WPS despite router having it disabled tells me that the node still has WPS active. If it were
truly disabled on the node, it
would not display in the WiFi app. Period. That is not the behavior of the WiFi app I use.
To accept your conclusion a) ignores what other users appear to be reporting in terms of active nature of WPS, b) ignores how the WiFi app behaves, and c) accepts the fact that there is inconsistent behavior in the app, in that if it was merely a way to say "this router supports WPS" and not an indication of if WPS was actually active or not, then
it should show for all bands on all nodes which it currently does not (i.e., the consistent behavior would be such that router and node 2.4 and 5 GHz bands would all display WPS, which they do not).
Bottom line: you seem to have an issue where the 2.4 GHz band on a node
always has WPS enabled to allow clients to connect, regardless of the router's settings. This needs to be fixed so WPS does not show in a WiFi scan on any nodes when it is disabled at the router. There is
no reason that WPS should display on a node's signal if it is turned off at the router. None.
EDIT:
@dabears and others... perhaps I am not being clear. If anyone else is able to replicate what
@dabears seems to have found, or if someone else can explain this in another way, I'd appreciate the support.
