Easy to use
The router is easy to use and its configuration interface is simple to use.
It changes its IP addressing scheme when it replicates a network, so there is no risk of IP address conflicts. The fixed IPs configured by the MAC addresses also change address plan, but keep the last selected IP range (in my case 192.168.0.100 changed to 192.168.1.100)
A small star less because during my tests, while being next to the router, I found the internet speeds slower than what I could have on my box in wifi (the router making an extension of my wifi with another SSID).
Another point that may be important for some, the antennas are not removable, so the TENDA AC23 takes a lot of space when you want to carry it.
