Good for the price
By Chris on Reviewed in the United States on December 5, 2025
For the price it's good, it has nice styling. Have to download a mobile app and create an account to set it up, and only has 1gig Ethernet ports, though it has been reliable and speeds are decent. Will probably try to upgrade to something with 10gig ethernet at some point, though those routers are much more expensive at the moment and would also have to upgrade ethernet adapters and network switch to use it. Some speedtest.net numbers with the mAX W21 Sonic 10gig fiber to Server - Frontier la,california using a MT7921 802.11ax wifi adapter from about 15 feet from the router are: (down/up Mbps) 1gig Ethernet 895.17(7ms) / 864.43(5ms) 720 Mb/s (5.2 Ghz wifi) 304.51(15ms)/248.46(30ms) 432 Mb/s (5.2 Ghz wifi) 400.86(38ms)/198.24(32ms) 229 Mb/s (2.5 Ghz wifi) 96.56(27ms) / 77.96(32ms) wifi speeds aren't as good as a t mobile 5g home internet router though the 1gig Ethernet port delivers close to maximum speed for gaming - amazon luna streaming, fortnite, halo infinite etc, the lower latency and consistency of Ethernet makes a big difference

Not worth the product to buy
By S. B. on Reviewed in the United States on December 1, 2025
This is a satellite for main W121 so if original is worthless and not usable then its not ideal to keep the extension satellite.
