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.

Compatibility questions tied to this model

Which NETGEAR RS300 Ethernet ports are 2.5 Gb/s?NETGEAR specifies one 2.5-Gb/s WAN port and two 2.5-Gb/s LAN ports on RS300, plus two 1-Gb/s LAN ports. A multi-gig client therefore has to be connected to the appropriate 2.5-Gb/s LAN port to negotiate above Gigabit.

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.
