After a city laptop OS upgrade, an outdated WLAN driver causes poor rate negotiation and choppy roaming between hallway APs, while identical hardware with current drivers performs well. What should the tech conclude?
Select an answer to reveal the explanation.
Short Explanation
Old drivers after a shiny OS upgrade are like bald tires on a new car—connection exists, handling suffers. Fresh drivers on the twin laptop prove the radio hardware is fine. Update the driver and watch rates and roaming settle down.
Full Explanation
Client drivers mediate rate selection, roaming triggers, and feature capability. An outdated driver after an OS change can degrade negotiated rates and roaming even when RF design and security are correct. Comparative testing with updated drivers on similar hardware confirms the driver as the variable. Updating the WLAN driver is the Domain 5.2 remediation for this performance class of issue.
