Why this answer matters
A Wi-Fi link can advertise rates above 1 Gbps while the router's wired WAN/LAN path remains limited by Gigabit Ethernet. That can create a real bottleneck on internet or local transfers.

Requirements
What has to be true
- Standard Archer AX55: Gigabit WAN/LAN ports as documented by TP-Link.
- Use the exact hardware model label before buying an adapter, switch or internet plan for multi-gig use.
- For >1 Gbps wired service, the entire path—modem/ONT, router port, cable, switch and client NIC—must support the higher speed.
Verify it yourself
Use this test sequence
Change one variable at a time so you know which requirement made the difference.
- 1
Check the router label for AX55 versus AX55 Pro.
- 2
Check the negotiated Ethernet link speed on the wired client.
- 3
Run a LAN transfer or router-side test when diagnosing a wired bottleneck; browser internet tests alone cannot prove the local link rate.
Limits
What this answer does not prove
- Wi-Fi marketing class numbers are aggregate theoretical link rates, not guaranteed internet throughput.
- Hardware revisions can differ by region; use TP-Link's support/download page for the exact hardware version.
