This firmware (version 2.22) is for the WZR-1750DHP only. Do not use it for other products.

New Features:

  • Added BeamformingEX functionality.
    This detects the location of wireless clients connected to the AirStation and automatically adjusts the radio strength. Keep enabled for normal use.
  • Added "No-IP" as a dynamic DNS service provider.
    You can access No-IP DDNS service (http://www.noip.com/) and create your account; register the hostname to access the AirStation"s LAN-side network from the outside (Internet-side). Navigate to "Advanced Settings" - "Internet" - "DDNS" and select "No-IP" from "Dynamic DNS Service", then enter your email address, password, and hostname to use No-IP service from the AirStation. This is available only when the AirStation is in router mode.
  • Now compatible with "NAT-Loopback" functionality.
    This enables you to use the same WAN-side IP address to communicate with LAN and WAN for the rules registered in "Advanced Settings" - "Security" - "Port Forwarding". This is available only when the AirStation is in router mode.

Improvements:

  • Removed "WPA-PSK AES" from available encryption methods.
    If your encryption method is "WPA-PSK AES", it will become "WPA/WPA2-mixed mode TKIP/AES mixed mode" when this firmware update is applied to the AirStation. Some devices may not be able to connect to the AirStation after this update. If it occurs, use WPS (PBC) or search its SSID to connect to the AirStation. Refer to the quick setup guide for more information.
  • "802.11n Protection" is now enabled by default.
    This prevents a performance decrease of 802.11n/802.11ac when 802.11n and 802.11ac are both used on the network. However, it may decrease 802.11a/802.11g/802.11b performance.
  • Added "Frame Burst" setting to the wireless configuration (2.4GHz). If disabled, the wireless performance may decrease. Keep enabled for normal use.
  • Added "Automatically select 20 or 40 MHz" option to high-speed mode setting for wireless configuration (2.4GHz).
    If selected, high-speed mode basically operates on "40 MHz", but if a 2.4 GHz wireless master device is detected, it switches to "20 MHz" automatically.
  • "Limit network scanning" is now configurable when the AirStation is in bridge mode.
    Enable this to avoid warning messages from certain security software.
  • Added "Edit AOSS client information" to "Advanced Settings" - "Wireless" - "AOSS" page.
    You can edit or delete registered AOSS wireless clients from this page.
  • Changed the working specification of "Use SSID and security settings from master" when "manual" is selected in "Advanced Settings" - "Wireless" - "Wireless Bridge" page as below:
    • Previous
      Used the same wireless settings (SSID/authentication/encryption) as the wireless master in both of 2.4 GHz and 5 GHz.
    • Now
      Uses the same wireless settings (SSID/authentication/encryption) as the wireless master only for the bandwidth connected to the wireless master. Uses the AirStation’s wireless settings in another bandwidth.

Bug Fixes:

  • Fixed the problem of the SSID not displaying correctly in AirStation configuration tool when the AirStation is in wireless bridge mode and "Use SSID and security settings from master" is configured.
  • Fixed the problem of PPPoE passthrough via wireless bridge not available when the wireless bridge is connected to the AirStation.
