Key settings related to 11n
|Note||The actual name and feature of the setting may vary depending on the AP. Check the user manual or contact manufacturer of your AP for details.|
Controls the channel your AP uses to communicate with client devices on your Wi-Fi network.
Most APs should have this set to Auto by default. We do not recommend changing this setting unless you:
- Have a good understanding of Wi-Fi channels
- Know how to determine the least congested channel in your environment
- Channel Width
For optimal performance and compatibility, enable support for all channel widths. If configured for 40MHz only, this setting prevents legacy devices that support only 20MHz from connecting to the AP.
- (Wireless) Mode
This setting controls the type of Wi-Fi devices (802.11a/b/g/n/ac) that can connect to the AP.
For optimal performance and compatibility, enable support for all wireless modes.
If configured for 11n mode only, legacy devices that support only 11a/b/g are not able to connect to the AP.
|Note||WEP and WPA-TKIP are not compatible with 802.11n.|
