After a technician updated the wireless APs to 5GHz, users report they have degraded Wi-Fi performance. The technician tests for interference but finds none. Which of the following should the technici

Selecting a different channel is typically done to mitigate interference, which the technician already ruled out as a cause.

Switching back to the 2.4GHz frequency would likely restore coverage but would negate the intended upgrade benefit of 5GHz's higher potential speeds and capacity.

Upgrading wireless drivers on user devices is a general troubleshooting step that might help with connection stability or feature support, but it wouldn't fundamentally address a widespread issue of degraded performance across multiple users due to 5GHz signal characteristics.

The 5GHz frequency band offers higher speeds but has a shorter range and poorer wall penetration compared to 2.4GHz, so if users report degraded performance without interference, adding more access points is necessary to provide adequate coverage for the 5GHz signal throughout the area.
