Is the U6-LR worth it?
It would have been nice to see a 2.5GbE port, but the U6-LR remains a fast Wi-Fi 6 AP with good range. It offers a wealth of features for a very fair price, and Ubiquiti's UniFi cloud management services are among the best in town.
Is ubiquiti overkill for home network?
Still, Ubiquiti's UniFi products can be overwhelming and overkill in many cases. Generally, home users should go with AmpliFi instead of UniFi.
What is the range of the UniFi U6-LR?
When deciding on how many access points you need, a good general rule is don't expect 5 GHz coverage to extend further than 2 walls or 30 feet away. The U6-LR extends this circle out a bit, but with the others APs, roaming to 2.4 GHz or getting low SNR 5 GHz performance is possible at the far edges.
