A field service technician is troubleshooting a corporate smartphone used inside a crowded multi-AP facility. The phone experiences severe throughput degradation and frequent packet loss while connected to the 2.4 GHz Wi-Fi network, despite displaying a strong signal indicator. A site survey reveals that the local access point is broadcasting on 2.4 GHz Channel 4, while neighboring access points are actively transmitting on Channel 1 and Channel 6. Which of the following actions should the technician take to resolve the mobile device's connectivity issue?
- Reconfigure the access point to broadcast on non-overlapping Channel 11.Cevap
- BChange the access point channel to Channel 3 to evenly divide frequency usage between Channels 1 and 6.
- CAssign a static APIPA address (169.254.10.15) to the mobile device to bypass wireless channel negotiation overhead.
- DUpdate the mobile device's IMSI stored in the network profile to force dynamic channel selection.
Cevap
Reconfigure the access point to broadcast on non-overlapping Channel 11.
In the 2.4 GHz wireless spectrum, each channel occupies 22 MHz of bandwidth while channels are spaced only 5 MHz apart. To prevent adjacent-channel interference, wireless networks must use non-overlapping channels (1, 6, and 11). Operating on Channel 4 causes overlap with both Channel 1 and Channel 6. Moving the access point to Channel 11 resolves the radio frequency interference for connected mobile devices.
