A network technician is troubleshooting severe wireless connectivity degradation and high packet loss for users on a 2.4 GHz Wi-Fi network in a dense commercial building. A site survey reveals that nearby access points managed by adjacent tenants are currently transmitting on channels 2, 3, and 5. Which of the following configuration changes should the technician make to BEST eliminate adjacent-channel interference?
- Reconfigure the access points to operate exclusively on standard non-overlapping channels such as 1, 6, or 11.Answer
- BSet the wireless access points to transmit on channel 4 to balance the frequency gap between channels 3 and 5.
- CReconfigure the local DNS server settings to automatically reassign IP address leases to connected wireless clients.
- DDeploy unmanaged Layer 2 switches at each client workstation area to split the wireless subnets.
Answer
Reconfigure the access points to operate exclusively on standard non-overlapping channels such as 1, 6, or 11.
In 2.4 GHz wireless networks, channels are 22 MHz wide but spaced only 5 MHz apart. To avoid adjacent-channel interference, wireless access points must be configured to use non-overlapping channels (channels 1, 6, or 11). Setting the access points to these standard channels prevents frequency overlap and restores network stability.
