When should I compare single-stream, parallel and reverse iperf3 tests?

Two iperf3 results can differ greatly because they used different options. A single stream, several parallel streams and a reverse-direction test are different workloads. Label the configuration before comparing numbers or declaring one router faster than another. Begin with the ordinary client-to-server test between authorized local computers. Record duration, software version and connection type. Avoid introducing several performance flags before establishing a repeatable baseline that resembles the task you want to improve.

Why can uploads remain slow when downloads are fast?

A connection can download quickly while taking much longer to upload a video or backup. The service may provide different capacities in each direction, and ongoing uploads can consume the smaller allowance before you start a test. Look up the upload speed included with the current plan. Do not infer it from the advertised download headline. Record the units and any provider guidance on expected performance so the target is based on the actual service.

Why might a work application fail while its VPN is connected?

The Connected label in a VPN client confirms a connection state, not universal access to every workplace resource. An application can still fail because of its name, route, service availability or account permissions. Keep those stages separate while gathering evidence. Check that the active VPN is the one your organization provides for this task. Microsoft advises obtaining workplace VPN settings or software from the organization. A personal privacy VPN is not a substitute for an approved connection to an internal resource.

Can a replacement USB-C cable slow a dock’s Ethernet connection?

A longer USB-C cable can make a desk neater while quietly changing a docking station's behavior. If Ethernet slows or disappears immediately after a cable replacement, investigate the laptop-to-dock connection before replacing the network cable. Save active work and reconnect the original manufacturer-supplied host cable. Use the same laptop port and Ethernet connection. If normal behavior returns, the replacement host cable becomes a strong suspect, although the result alone does not identify its exact electrical limitation.
