      The following router features are not available (grayed out) when
      the router is in AP mode:

          o Guest Network
          [...]

   On these routers, a "guest" network is not a separate network, but
there are firewall-like rules (enabled by default) which can limit the
ability of "guest" client devices to communicate with non-guest client
devices.  (Those firewall-like rules are implemented in the router
section of the device, which is why that functionality is lost when the
router is configured as a wireless access point.)

   I'm unaware of any such thing.
