Extremely rock solid. I haven't touched them in 5 years or so and haven't had to do any resets nor have dropouts or anything. Great signal strength. Probably have 30 devices at a time connected to each one.
Bump. Still have these AP's. Now I also have a PoE+ switch to power them, or use the injectors.
TPLink SG1060PE switch. 8 PoE+ ports, 8 regular ports. Gigabit. Reset to factory. Plug and play into your router, or go through admin panel to set up with static or whatever you want. Comes with power cable and rack mount ears and screws. Great switch, but needed to upgrade to 24 port PoE+. $140 OBO. 3 weeks from brand new.
Both working and were adopted to a controller running on Raspberry Pi. POE or POE+ powered. I have one POE injector you can have if needed. View attachment 182607
