A client SSID enforces WPA2-Enterprise but the test script checks only DHCP success for an already connected laptop is a separate situation normally addressed by: Restart association and validate security negotiation plus the RADIUS assigned role before checking IP. This change record concerns a different issue, specifically: An AP change disables legacy rates but the team never checks whether registered classroom devices still join.

A wireless classroom AP supports both 2.4 and 5 GHz but the target scanner profile needs 2.4 GHz compatibility is a separate situation normally addressed by: Keep the permitted 2.4 GHz radio enabled for the scanner group rather than forcing unsupported 5 GHz-only access. This change record concerns a different issue, specifically: An AP change disables legacy rates but the team never checks whether registered classroom devices still join.

A classroom rollout uses an AP mounting orientation different from the manufacturer's recommended antenna pattern is a separate situation normally addressed by: Reorient the AP according to the device radio design and site RF survey. This change record concerns a different issue, specifically: An AP change disables legacy rates but the team never checks whether registered classroom devices still join.

Export the current switch VLAN and routing inventory and reconcile it with the authoritative IP address register belongs to a different operational case: A new clinic wing needs a campus network extension but no one has recorded the existing IP subnets or VLAN ownership. It does not target the specific issue here; the intended remedy is: Inventory client band support and obtain current regulatory RF measurements for 6 GHz where permitted.

Record regulatory band, channel-width assumptions and power design for each surveyed RF zone belongs to a different operational case: A wireless design names AP positions but not channel plans or expected transmit power ranges. It does not target the specific issue here; the intended remedy is: Inventory client band support and obtain current regulatory RF measurements for 6 GHz where permitted.
