A network technician is troubleshooting intermittent connectivity and high latency reported by users in an open-plan office. The office uses a 2.4 GHz Wi-Fi deployment. A wireless spectrum analysis shows several nearby access points broadcasting on channels 2, 4, and 5. Which of the following is the MOST appropriate configuration change to resolve the wireless interference?
- Reconfigure the access point to transmit on channel 1, 6, or 11.Cevap
- BChange the access point channel to channel 3 to sit midway between the surrounding active channels.
- CReconfigure the local DHCP server to decrease the IP address lease duration for wireless clients.
- DReplace the access point's uplink switch with an unmanaged Layer 2 switch.
Cevap
Reconfigure the access point to transmit on channel 1, 6, or 11.
In 2.4 GHz wireless networks, each channel spans 20 MHz of spectrum. To avoid adjacent-channel interference, wireless networks must use non-overlapping channels. The standard non-overlapping channels are 1, 6, and 11. Changing the channel configuration to one of these non-overlapping channels resolves signal interference caused by neighboring networks using channels 2, 4, and 5.
