MAX Transit Cat 18 Basic Configuration for max speed

Yes. You should open a ticket to find out why the bandwidth of your Wifi as WAN device is not passed through to the Max Transit. I do know that your latency will be higher since more hops. Could it have something to do with your Outbound Pollicies? Make sure that your Wifi as WAN WAN is prioritized correctly. I also know that you are burdening your antennas with incoming AND outgoing traffic as well as the router CPU. Just some thoughts.
