ntce qos priority {category} {priority}— assign certain priority for certain categoriesntce qos enable— enable QoS processing for thentce(network traffic classification engine)
The Traffic classification engine and IntelliQoS system component is replaced by the Traffic classification engine system component of the KeeneticOS. It implements the detection and classification of applications and protocols.
Categories and Applications diagrams appeared in the Host traffic monitor menu of the Web Interface. Also, a new item, Application Traffic Analyzer, appeared in the Status section. Currently, new sections become visible after the component is installed and the service is enabled via the
service ntceCLI command. The component operates autonomously and does not depend on any external services. [NDMS-1476, NDW-2109]
The KeeneticOS build system is now available on GitHub. You can use the Keenetic Software Development Kit (SDK) to build a customized Keenetic firmware image with your own services and scripts. [NDMS-1398]
Added a configuration option to allow automatic discovery of devices and services via mDNS protocol on different network segments, regardless of traffic isolation between them. Use the
mDNS reflectorcommand to control the forwarding of mDNS packets between network segments. [NDMS-1418]mdns reflector enforce— enable reflector regardless of segment isolation;mdns reflector disable— disable reflector regardless of segment isolation.
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]
Removed an error message that occurred if an IP address was configured instead of a URL (Uniform Resource Locator) for a DoH (DNS over HTTP) server:
Resolver prefix doesn't appear to contain a hostname. [NDM-1938]Access to WebDAV server resources from the local network is now allowed for the
security-level privatemode. [NDM-1890]Enabled centralized Wi‑Fi
country codeconfiguration from Wi‑Fi system Controller, and blocked this setting on Extenders. [NDM-1921, NWI-733]Corrected the calculation Distance to the cell tower for QMI modems on LTE TDD (Time-Division Duplex) cells. [NDM-1916]

Added the ability to use multiple partitions with the same volume labels. Restored operation with user volumes labeled
/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]
The Active connections information sheet moves to a separate tab on the Diagnostics page, providing a list of sessions established via your Keenetic device. [NWI-414]
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]
Added a Compressed RAM disk for system swap (zRAM) toggle to the System settings page. [NWI-405]
Improved DNAT session recognition by the Traffic classification engine system component. [SYS-319]
Implemented stopping of the Traffic classification engine service to free system memory before a KeeneticOS update. [NDM-1756]
The system Debug control relocates to a dedicated tab in the Diagnostics section. [NWI-401]
Improved the application identification and traffic accounting accuracy of the Traffic classification engine system component. [SYS-309]
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]
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]
Added new IntelliQoS priority configuration page in the Web Interface. It ensures inbound, and outbound, bandwidth for prioritized applications and tasks via pre-defined, drag-and-drop category group presets. [NDW-2413]
Updated the Web Interface of the KeeneticOS to address the CVE-2021-23017 vulnerability.
Added Password protected access to web applications running on your network via the KeenDNS service. [NDW-2202]
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]
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]
Removed Wi‑Fi extenders from the list of devices that can be assigned a DNS filtering policy profile on the Internet safety page. [NDW-2108]
The firmware image build with the Keenetic SDK is now compatible with the Keenetic Recovery Utility for Windows OS. You can use this utility to upload a firmware image to your Keenetic device. [NDMS-1530]
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]
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.
Fixed
Fixed the inability to set up a static DNS server address with the custom port setting in the Web Interface, for example —
1.1.1.1:5353. [NWI-766]Fixed the forced disconnect of live Wi‑Fi clients when removing them from the Whitelist of the Wireless ACL. [SYS-400]
Fixed the false advertisement of 802.11k capabilities in Wi‑Fi network beacons. [SYS-414]
The Device list no longer shows phantom devices when an ISP network shares the same VLAN IDs with network segments configured in the Keenetic device. [SYS-422]
