Why this answer matters
The AP's radio has aggregate capacity beyond a single Gigabit link, so connecting it to 1GbE can become an upstream ceiling even when Wi-Fi itself is healthy.

Requirements
What has to be true
- 2.5GbE switch port/cabling for a >1GbE uplink.
- PoE+ power budget.
Verify it yourself
Use this test sequence
Change one variable at a time so you know which requirement made the difference.
- 1
Check the UniFi switch port for 2.5GbE negotiation.
- 2
Verify PoE status/budget.
- 3
Use endpoint tests only after confirming the infrastructure link.
Limits
What this answer does not prove
- A 2.5GbE uplink does not guarantee one client receives 2.5 Gb/s.
- Internet, RF and client hardware can all dominate results.
