Network+ PBQ 2: Wireless Configuration & Troubleshooting

Scenario

A small business has poor wireless performance. Users report dropped video calls, low speeds near the conference room, and confusion between staff and guest Wi-Fi. The office has 2.4GHz, 5GHz, and 6GHz-capable access points.

Your task: Choose the best wireless configuration and troubleshooting decisions.

1. Best encryption/security option for the staff wireless network:

2. Guest users should be placed on:

3. Best tool to identify channel overlap/interference:

4. Best 2.4GHz non-overlapping channel set:

Coverage and Design

5. Feature that helps clients move between 2.4GHz/5GHz/6GHz more intelligently:

6. Best antenna type for covering a large open office from the center:

7. Users in one corner have weak RSSI. Best next step:

8. Best authentication model for enterprise staff Wi-Fi using centralized credentials:

Instructor Answer

Use WPA3 when supported; WPA2 is still common where WPA3 is unavailable.
Guest Wi-Fi should be segmented from trusted internal networks.
A Wi-Fi analyzer helps identify channel overlap, interference, and signal issues.
On 2.4GHz, use non-overlapping channels 1, 6, and 11.
Band steering can help steer capable clients to better bands.
Omnidirectional antennas radiate broadly for open areas.
Weak coverage should be validated with a wireless survey/heat map before moving APs.
Enterprise authentication is preferred for staff networks that use centralized identity.
