Home-lab WiFi yak shaving rabbit hole from hell.
1. UAP-AC-Pro only negotiates 100baseT on an 8m cable with PoE injector
2. I re-crimp both ends of the cable, multiple times
3. I replace the switch with an RB4011, move the (48V) PoE injector in front of the switch
4. Still 100baseT, but the AP is now resetting when it gets warm
5. I replace the UAP with a hAP AC
6. The hAP negotiates GbE, but iwlwifi (AX200) firmware crashes on connect:
