A public-safety laptop had chronically low MCS and data rates until the failing WLAN driver was replaced; rates then returned to expected levels on the same AP. What does this confirm?
Select an answer to reveal the explanation.
Short Explanation
When swapping the sick driver brings MCS and rates back on the same AP, you have your culprit. Same radio path, new software path—performance returns. That is a clean driver confirmation, not a redesign trophy.
Full Explanation
Restored MCS and data rates after replacing a failing client driver, without changing AP RF settings, validates that the driver was the performance bottleneck. Controlled comparison before and after is strong evidence in Domain 5.2 driver troubleshooting. Technicians should not escalate to coverage redesign when a driver swap fully remediates rates. Documenting the confirmation closes the incident at appropriate technician scope.
