Why this answer matters
A Gigabit switch port creates a wired ceiling before Wi-Fi is considered, while insufficient PoE power is a separate infrastructure problem from RF/client performance.

Requirements
What has to be true
- 2.5GbE switch/uplink path to negotiate above 1 Gb/s.
- PoE+ power source within Ubiquiti's requirements.
Verify it yourself
Use this test sequence
Change one variable at a time so you know which requirement made the difference.
- 1
Check negotiated switch-port speed in UniFi Network.
- 2
Confirm the power source reports the expected PoE mode and budget.
- 3
Compare client latency/jitter separately from link speed.
Limits
What this answer does not prove
- Wi-Fi PHY rates are not guaranteed internet throughput.
- Client radio capabilities, channel width and RF conditions remain limiting factors.
