After adding a supplemental access point inside the MRI suite to resolve a coverage dead zone, what is the most effective way to validate that the fix actually restored usable Wi-Fi coverage in that room?

The original symptom was a specific, physical coverage dead zone, so validating the fix means directly re-measuring coverage in that exact space, not just confirming an administrative or fleet-management milestone like the AP successfully joining the controller, which only proves the AP is manageable and online, not that it's actually radiating usable signal into the previously dark room. A walk-test with a wireless survey tool, or reviewing an updated coverage heatmap for that area generated by the WLAN management platform, directly measures what the original problem was about: signal strength and connectivity at specific points inside the room, which is the only way to confirm the dead zone is genuinely resolved rather than assumed resolved. Firmware version matching across the fleet is a legitimate operational best practice for consistency and support, but it has no bearing on whether this specific coverage problem has been fixed. Asking about the MRI machine's own functioning is unrelated entirely, since Wi-Fi coverage and the imaging equipment's operation are independent systems, and this scenario is troubleshooting the wireless issue rather than any imaging equipment. A caveat: because MRI rooms are shielded specifically to control RF, revalidate coverage with the actual MRI machine running its normal sequences if possible, since the equipment's own operation can introduce localized RF noise that a walk-test performed while it's idle wouldn't capture.
