Model facts that change the troubleshooting path

01

TP-Link rates Archer AX55 as AX3000 Wi-Fi 6: 2402Mbps on 5GHz plus 574Mbps on 2.4GHz under its stated conditions.

02

TP-Link specifies one Gigabit WAN port, four Gigabit LAN ports and one USB 3.0 port on the Archer AX55; it is not a 2.5GbE router.

Test matrix

What to test and what a pass actually tells you

Run the test closest to the symptom. A passing result narrows the diagnosis; it does not certify the entire device.

Browser Online Status TestCheck the browser online state, available connection hints, and a short round trip to DeviceOK.

A pass proves this browser can reach DeviceOK through the current network path; link negotiation and router counters require OS/router evidence.

Browser Latency TestMeasure several browser-to-DeviceOK request round trips as a quick connection responsiveness check.

A pass proves this browser can reach DeviceOK through the current network path; link negotiation and router counters require OS/router evidence.

Browser Network Timing Variation CheckRun repeated HTTP round trips to DeviceOK and show timing variation between samples.

A pass proves this browser can reach DeviceOK through the current network path; link negotiation and router counters require OS/router evidence.

Network Information CheckRead browser-exposed connection type, estimated round-trip time, downlink, Save-Data state, and online status where supported.

A pass proves this browser can reach DeviceOK through the current network path; link negotiation and router counters require OS/router evidence.

Public IP Address CheckSee the public-facing IP address DeviceOK receives for this web request.

A pass proves this browser can reach DeviceOK through the current network path; link negotiation and router counters require OS/router evidence.

Diagnostic focus

Problems worth separating on this model

01 · Internet works over Ethernet but not Wi-FiReproduce this symptom independently, then choose the closest live test or exact compatibility record before changing drivers, firmware, cables or hardware.

02 · One client vs whole-network issueReproduce this symptom independently, then choose the closest live test or exact compatibility record before changing drivers, firmware, cables or hardware.

03 · Gigabit port limit mistaken for 2.5GbEReproduce this symptom independently, then choose the closest live test or exact compatibility record before changing drivers, firmware, cables or hardware.

04 · Latency/jitter instabilityReproduce this symptom independently, then choose the closest live test or exact compatibility record before changing drivers, firmware, cables or hardware.

05 · Firmware/configuration requiring TP-Link managementReproduce this symptom independently, then choose the closest live test or exact compatibility record before changing drivers, firmware, cables or hardware.

Compatibility questions tied to this model

Does the standard Archer AX55 have a 2.5GbE port?The standard Archer AX55 is documented with Gigabit Ethernet: one Gigabit WAN port and four Gigabit LAN ports. TP-Link's Archer AX55 Pro is a different model and is the version that adds 2.5 Gbps connectivity. If you need multi-gig wired internet, make sure you are not confusing AX55 with AX55 Pro.

Evidence handoff

If the browser cannot reach the suspected subsystem

Keep the browser result as one observation, then move to the operating system or manufacturer diagnostic that can see the protected hardware state. Do not interpret an unsupported browser API as a failed component.
