Improved
Enhanced Wi‑Fi Network protection: WPA2 Enterprise exchange with a RADIUS server now has Network name (SSID) in the
Called-Station-Idmessage —'50-FF-20-AA-BB-CC:Keenetic-5555'. [SYS-9]

/storageand/flash. [NDM-1805]Implemented brute-force protection for remote access to the device via the KeenDNS domain name in the Cloud access mode. [NDM-1804]
The KeeneticOS update process is optimized to run in the background to minimize system downtime. Keenetic has dual flash memory with active and backup KeeneticOS images to ensure fail-free automatic upgrades. When a new version of the operating system is released, the device will download, store and check the integrity of the software image in the backup partition first, without interrupting the main operation. Then the Keenetic device reboots, running the updated KeeneticOS version. Internet access will be briefly interrupted only during the device reboot. [NDM-1861]
The hostname value is added to the Syslog message's payload when sending records to a server to simplify log analysis from multiple Keenetic devices. [NDM-1872]
Improved security: After changing user credentials, KeeneticOS cleans up active management sessions via the Web Interface and the Keenetic mobile application. [NDM-1860]
When a wired Ethernet backhaul link is used to attach a Wi‑Fi System Extender to a Wi‑Fi System Controller, setting up custom Wi‑Fi channels on the Extender is now possible. Setting non-overlapping Wi‑Fi channels on different Wi‑Fi System nodes will maximize wireless clients' performance. If a wired Ethernet backhaul link disconnects, the Extender will automatically switch to a Mesh wireless backhaul link to resume operation. In this case, depending on the Mesh wireless backhaul interface, the corresponding Wi‑Fi channel on the Extender will follow the backhaul link. Once a wired Ethernet backhaul link is restored, the Extender will automatically use wired backhaul and preset Wi‑Fi channels. [NDM-1801]
Restored receiving SMS messages for the DW5821e (T77W968) modem module with updated firmware. [NDM-1839]
Web UI of the Download station application is now available at the

A Wi‑Fi System Extender will stop broadcasting Wi‑Fi networks if the backhaul connection to the Wi‑Fi System Controller is lost, to help Wi‑Fi clients re-connect to a working Wi‑Fi System node faster. [NDM-1707]
The display format of the ECI (ECell ID) identifier is changed from hexadecimal to decimal. eNodeB ID and Sector ID parameters are added to the QMI-type modem statistics. [NDM-1732]
Added a Compressed RAM disk for system swap (zRAM) toggle to the System settings page. [NWI-405]
Added a Hardware network accelerator (HWNAT) toggle to the System settings page. [NWI-405]

As of now, the Keenetic Traffic classification engine recognizes 1400+ of the most popular Internet applications. In addition, Uncategorized traffic is now visible in the Applications and Categories views of the Traffic Monitor. [NDM-1210]
Implemented automatic merging of the least important data to the Uncategorized group to optimize memory usage by the Traffic classification engine and enable protection against memory overflow. [NDM-1681]
Implemented support for dialog-type USSD (Unstructured Supplementary Service Data) queries for QMI-type modems. [NDM-1273]
You can now easily configure remote access to the Web Interface of a connected USB modem. When adding a new KeenDNS web application, select your modem from a drop-down list of hosts. [NWI-325]
Seamless navigation from Wi‑Fi System Controller to Extenders is available now. Click the Extender name on the Mesh Wi‑Fi System page to jump to the Web Interface of the Extender. Each Extender has a unique navigation web address under the
*.keenetic.iodomain. Security tokens and automatically installed Let's Encrypt SSL certificates ensure safe and secure operation. [NDM-1287, NWI-323]Added the Optimization mode selector to the IPsec VPN server application settings. It changes the set of supported encryption algorithms, as follows. [NDM-1259, NWI-327]
Default — enables all encryption algorithms except
DESand3DES;Legacy — enables both
DESand3DESfor compatibility with legacy clients;Performance — enables modern encryption algorithm
CHACHA20-POLY1305only, for faster and secure data exchange with supported peers.
It is now possible to edit Speed limit settings for devices with internet access blocked according to schedule on the Device lists page. [NDW-2427]

Redesigned the Access to web applications running on your network section of the Domain name > KeenDNS page for better visibility and easy management. [NDW-2203]
Added the Auto option for the KeenDNS operating in IPv4 mode, providing automatic detection of obtained IP address type and flexible operation if this IP changes from time to time or you have a secondary/backup Internet access connection. [NDW-2243]
Added the Disconnect from the network option in the Data usage & limit page for external QMI type 4G/3G modems. It instructs Keenetic to disconnect the 4G/3G modem from the mobile network when the data limit of your mobile plan is exceeded. [NDW-2230]
Updated the embedded DSL modem firmware version to
5.12.23.5.
ICMP - Host unreachablereplaces theDROPaction for the internal firewall rule of KeeneticOS when the user's device is accessing a blocked DNS over HTTPS (DoH) / DNS over TLS (DoT) DNS server. This change helps to speed up fallback to allowed DoT/DoH DNS servers on the Keenetic device. [NDMS-1470]It is now possible to use
%and^characters in the Username field of a DDNS profile. [NDMS-1255]
The KeenDNS settings now allow specifying an IP address and FQDN as the HTTP proxy destination address in the Access to web applications running on your network section of the Domain name page. [NDW-2201]

Implemented a new smart queue management algorithm — NDM Fast Queue (NFQ). NFQ is CAKE-based, and optimized for speeds above 24 Mbit/s. When you limit the Internet connection speed for a host or network segment at a rate above 24 Mbit/s, the NFQ algorithm performs shaping. For rates below 24 Mbit/s, the CAKE algorithm does the job. [NDMS-1247]
We released a redesigned graceful shutdown of storage devices, to prevent USB storage corruption at router reboot or USB disk eject. Improved USB xHCI controller initialization. [NDMS-1489]
DHCP server options 121 and 249 now allow configuration of routes with destination
0.0.0.0/0. [NDMS-1222]The CLI command for adjusting the TTL value of incoming IP packets has a new syntax: [NDMS-1419]
interface ip adjust-ttl (set | inc | dec)— old syntax, obsolete now;interface ip adjust-ttl recv {recv}— new syntax.
Improved compatibility of the File and printer sharing (TSMB CIFS) system component with Sony PlayStation 2. [NDMS-1018]
