Channel Width Select the channel width of the EAP. The available options differ among
different EAPs.
For some EAPs, available options include 20MHz, 40MHz and 20/40MHz.
For other EAPs, available options include 20MHz, 40MHz, 80MHz and
20/40/80MHz.
When the radio mode includes 802.11n, we recommend you set the channel
bandwidth to 20/40 MHz or 20/40/80MHz to improve the transmission

• To increase the available number of channels within the limited total
• To avoid interference from overlapping channels occupied by other
• Lower bandwidth can concentrate higher transmit power, increasing

you keep the default setting.
