Hi, Just a few quick suggestions. These are standard protocols for testing
any router (whether it is new or used, or discontinued or not). Please check
the following link below for basic solutions:

https://www.makeuseof.com/tag/commands-manage-wireless-networks-windows/

I have found the ipconfig command and the ping command quite useful. So will
the router table command.

What this does is show the routing and porting of the system (especially if you
want to use port forwarding). Remember, that in addition to this, there will be
the needed security protocols for the 2.4 GHz and the 5 GHz bands (and perhaps
for the various sub-bands as well). Bear in mind, this is high end FM. Check and
verify connectivity, range, and throughput.

Hope this helps.

Sincere regards,

Charles Lucas
