Just got myself a Wifi 6 LR today to replace an AC-Lite. So far so good, signal seems to be better by around 10-15% and throughput higher all round. Got it plugged into one of my trusty Netgear GS110TP v2's which are 802.3af only not 802.3at (given the LR states 802.3at only at 16.5W max) - works fine and draws between 7-9W according to the Netgear POE port power monitoring.
Yes, with all the bad news around the routers/firewalls it’s easy to forget how good the good bits are.
