Hi Everyone,


Today we are releasing v8.5.1 for airMAX AC devices.   You can download it in the Downloads Section HERE.




- New: Wireless Network Protection feature. This feature is enabled on AP and protects the airMAX 
network against de-authentication attacks. airMAX AC and airMAX M client devices are
supported but they must be used with an airMAX AC AP. We recommend upgrading client devices
first before enabling this feature on AP. - New: DNS settings on WAN for IPv6 - New: Fresnel view on Dashboard - New: Device Height setting in the System tab - New: Indication of chain imbalance on Dashboard and in the Station List (0-3 dBm - green, 4 dBm - yellow, >= 5 dBm - red) - New: Custom hosts entries support in system.cfg (See below for details) - New: Help file for Device Height setting - New: UNMS status icon on the top of airOS - New: UNMS agent upgrade to v0.3.10 - airMAX-ac FF: Introducing ReSE (Receive Signal Enhancement) feature. Enabling it improves
receiver performance for both AP and STA, and helps in combating interference. - airMAX-ac FF: Scheduler improvements. We recommend upgrading both AP and stations, or
recommend stations running 8.5.0 or 6.1.4 and above, if you decide to update the AP alone. - airMAX-ac FF: Ethernet flow control performance improvements - airMAX-ac FF: Fixed wrong Airtime RX reporting for Station - airMAX-ac: Maximum supported CPE/Station count limited to 50 for 2AC - airOS stability improvements Regulatory updates: - Extended UNII-3 band up to 5725-5850 MHz for United Kingdom - UNII-2 channels support for NanoStation AC and NanoStation AC loco Fixes: - Fix: IPv6 forwarding - Fix: Traceroute tool improvements - Fix: AirView stability fixes & data representation improvements - Fix: Wrong channel width is set on Station when Auto-channel width is selected - Fix: Wrong distance in PTP mode - Fix: Many scan results causes Site Survey crash - Fix: Speed Test reporting issues - Fix: Make airMagic refresh more often (every minute) - Fix: Excessive Pause Frames on some switches - Fix: Maximum TX Data Rate selection (restricted to the range of 2x - 8x) - Fix: Full restart is done instead of fast restart when applying changes after first login - Fix: Station cannot reconnect if RADIUS server is down more than hour - Fix: dnsmasq is not restarted after uploading system.cfg with custom hosts entries WEB UI: - WEB UI: Dashboard and airLink map view improvements - WEB UI: Show airTime and Throughput on Dashboard - WEB UI: Show SSID on Dashboard - WEB UI: Show Remote GPS Signal on Dashboard - WEB UI: Improved redirect to new IP address after device reset, reset to defaults, IP change, and Web port change - WEB UI: Fixed redirect from HTTP to custom HTTPS port (not 443) - WEB UI: Lifted username restriction introduced in v8.5.0 for old usernames - WEB UI: List bridge interfaces between parentheses in WAN/LAN Interface - WEB UI: Set the cursor position on Username field in Login page - WEB UI: Enter key doesn't start Ping and Traceroute tools - WEB UI: "Backup file uploaded" notification doesn't disappear - WEB UI: Wrong dhcp6c and upnp interfaces are set when PPPoE is enabled - WEB UI: Error parsing DHCP6 server leases - WEB UI: Sometimes blank page opens when logging into Web - WEB UI: Device details window adjustment - WEB UI: Old authenticated sessions were not cleaned up.
