Step by Step Detailed Comprehensive Explanation with All CompTIA References:
Analysis of the Problem:
Switching to the 5GHz frequency improves speed but decreases range and penetration through walls compared to 2.4GHz.
Users experience degraded performance likely due to poor coverage at the 5GHz range.
Option Evaluation:
A: Select a different channel: Useful for interference resolution but not coverage improvement. Incorrect.
B: Switch the Wi-Fi back to 2.4GHz frequency: This downgrades the network speed, which isn't a preferred solution. Incorrect.
C: Upgrade the wireless drivers on the users' devices: Unlikely to resolve coverage issues. Incorrect.
D: Add more access points for better coverage: Improves coverage in areas where 5GHz struggles. Correct.
Reference: Domain 2.5 of the 220-1101 objectives emphasizes understanding wireless network configurations.
