After waiting for the Power and the Wifi lights to turn on steadily, I connect the LAN1 to LAN1 on both devices, but the extender shows up as Client instead of an extender.

I assume caused by this; the setup process of the Extender does not continue. The link light never turns on.

If any log files are needed to troubleshoot, I’ll be happy to include them as a reply so long I’m told where to find them.
