A new computer was plugged into a port that was used by a legacy network printer prior to the completion of an office remodeling project. The user who was assigned to the new computer has been…

When a port was previously used by a legacy network printer, it's common for network administrators to hard-set its speed (e.g., 10 Mbps) and duplex (e.g., half-duplex) settings on the switch to match the older device's capabilities. A new computer, expecting auto-negotiation to 1 Gbps full-duplex, will experience a speed and duplex mismatch, leading to significant performance degradation and slow network speeds.

While a VLAN misconfiguration could cause no connectivity or incorrect network access, it wouldn't typically manifest as slow network speeds if connectivity is present.

BIOS settings primarily affect hardware initialization and boot processes; while network boot options exist, they are unlikely to be the cause of slow network speeds after the OS has loaded and drivers are updated.

The technician already swapped out the patch cable (from the computer to the wall), so replacing the permanent cable run (from the wall to the patch panel) would be a more drastic and less likely step to resolve a speed mismatch issue, especially if the link light indicates connectivity.
