I have now located and am now running on an ASUS RT-ARCH13 router connected
to Comcast. This device claims WiFi5 compliance with 11ac and CCMP.

Still stuck at 11ng and only connects at 2.4G.

The 5G SSID does not show up at all, though my phone shows it and connects
successfully. Attempts to manually scan return instantly and list scan
always list the exact same data including S/N, so it does not seem to
actually scan.
