Note
  • The setting 802.11n Mode is available only for the following legacy adapters. For other adapters use the 802.11n/ac Wireless Mode​ or HT Mode:
    • Intel® WiMAX/WiFi Link 5350
    • Intel® WiMAX/WiFi Link 5150
    • Intel® WiFi Link 5300
    • Intel® WiFi Link 5100
    • Intel® Wireless WiFi Link 4965AGN
  • The setting 802.11n/ac Wireless Mode or HT Mode determines the supported data rates, or Throughput mode, where:
    • HT=High=802.11n
    • VHT=Very High=802.11ac
    • Disabled=802.11a/g rates

Make sure you've configured your access point (AP) or Wi-Fi router for 11n mode. If you aren't sure if the AP is configured for 11n, contact your AP manufacturer.

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.
  • Channel

    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 don't 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 aren't able to connect to the AP.

Note WEP and WPA-TKIP aren't compatible with 802.11n.
