Changes & Features (TNA-303L-beta-1, rev 8503) 5/21/26

  1. Dashboard changes:
    • Add option to remotely bounce the eth0 port from the ethernet status widget.
    • Add option to make a DHCP lease static from the network status widget.
  2. Wireless changes & fixes:
    • Update 60GHz wireless driver to include fixes to address "MR" wireless errors that occurred in cooler temperatures for certain models.
    • Fix issue that may have prevented a station from connecting to an AP in the case where a large number of stations are already connected.
    • Add support for new configuration option to support 60GHz client isolation.
  3. System Settings changes:
    • Add latitude, longitude, and device description fields to the System settings configuration page. 
  4. Networking changes & fixes:
    • Add new configuration option to control whether the ethernet interface(s) are included in the management bridge when management VLAN is enabled in station mode.
    • Add support for carrier drop. 
    • Add a new setting for "LLDP forwarding" to allow LLDP packets to flow through the radio.  
    • Add ability to disable the DHCP server in client router mode.
    • Add port forwarding support in client router mode.
  5. Services changes:
    • SNMP Server: Add new option to support AES-256/SHA-256 encryption.
    • SNMP Traps: Add trap server port as a new configuration option.
  6. SNMP changes:
    • Add support for AES-256/SHA-256 encryption/authentication.
    • Add device description to the system extensions private MIB.
    • For wireless peers, expose wireless peer target RSSI, wireless peer IPv4 and IPv6, and wireless peer firmware version fields.
    • The private MIB has been updated here.
  7. SNMP traps changes:
  8. Tools changes:
    • Logs: add ability to view different device logs, one of which includes the device's system timestamp.
  9. API changes:
    • Add config test mode support to the /config route.
    • Add new /aiming route to enable/disable aiming mode.
    • Expose tx/rx byte and packet counters for the wlan0 (60GHz) radio in the wireless /stats route.
    • Update ethernet stats/ to include tx/rx byte and packet counters to match other TNA products
    • Expose device location, latitude and longitude in the system /stats route.
    • Add support for all new config keys mentioned above.
  10. Other changes:
    • Allow unknown multicast traffic to passthrough the radio (including OSFP)
    • Add support to recognize the TNA-305X model variants.
    • When insecure HTTP is disabled, redirect links automatically to the HTTPS equivalent.


Breaking changes:

  1. Speedtest has been updated to be compatible with the version used on the TNA-305X models.  It will no longer function between devices running v.15.0 and other TNA devices running firmwares older than 1.15.0 (e.g. 1.12.3).

Other upgrade notes:

  1. Please note that after your device is upgraded, additional time will be needed to flash the 60GHz modem.  
  2. If your device is configured to use DHCP client to obtain the management IP, please note that the main bridge MAC is not set to eth0's because of the upgrade process, and the device may boot back up with a different IP.
  3. The new wireless driver is compatible with the previous version in all v1.12.X firmwares.


Known issues:

  1. Speedtest reports slower speeds in the TX direction, but this does not affect actual device performance. [Fixed in beta-2]
  2. Latitude & longitude use incorrect validators.  [Fixed in beta-2]


Version 1.12.0 Firmwares


Version 1.12.4 Dec 10, 2025


This release adds support for new model variants and also introduces a new "client router" networking mode.  The antenna beambook has also been updated.


Changes (TNA-303L-beta1/final rev 7781):

  1. Add support for the TNA-303L base model and to recognize the TNA-305X model. 
  2. Add a new "Client router" networking mode that allows any 303L to operate as a router when 60GHz client mode is enabled. You can read more about it in the full web UI manual.  
  3. Add additional USM support to the SNMP server when running SNMPv3. 
  4. The antenna beambook has been updated with some optimized sectors for certain antenna kits.
  5. Update event log so that sensitive info, such as user passwords, etc, are hidden from view.
  6. Fix misc UI dashboard layout issues.
  7. Other small improvements or bug fixes not really worth noting here.


Known issues:

  1. DHCP lease time changes didn't take affect in the pre-release version of this firmware, but has been fixed in the beta-1 release.
  2. Speedtest will not be compatible with 305X models until a future firmware release.


What happened to version 1.12.3?  v1.12.3 was a limited-feature release that added support for the TNA-303L-65-LIB (link-in-a-box) model, so a public release wasn't necessary.


Version 1.12.2  Aug 28, 2025


This is a service release targeting the new model TNA-303L-65.


Changes (TNA-303L-final, rev 7713) 8/29/2025:

  1. Restored traffic control functionality.
  2. Fix bug that allowed an insecure password to be set at first login.
  3. Fix bug resulting in missing fields in the wireless API stats output.
  4. Allow to set a duration in the aiming tool.
  5. Remove some spurious log messages.
  6. Add support to recognize the TNA-303L-65 "link in a box" variant.


Changes (TNA-303L-beta-5, rev 7665) 8/5/25:

  1. A log overrun issue has been identified and fixed. This issue results in the device eventually running out of memory.  This is considered a critical issue. 


Changes (TNA-303L-beta-4, rev 7663) 7/28/25:

  1. Fixed the ethernet link status LED.
  2. Fixed a bug related to PTP mode (see known issue #5 below).
  3. Other misc improvements.


Changes (TNA-303L-beta-3, rev 7620) 7/8/25:

  1. Internal speedtest results are now accurate in both TX and RX directions. 
  2. A bug has been fixed which prevented network settings from taking affect when changing from DHCP static to client mode, without changing any other settings. 
  3. Fixed the site survey and temp channel change actions on the 303L.
  4. Fixed a web UI issue where a missing or misconfigured 60GHz radio caused the dashboard to show a system/internal error.  


Changes (TNA-303L-beta-2, rev 7613) 6/24/25:

  1. Added support for the 2.4GHz Mediatek MT7610U USB Wi-Fi dongle for device management.  Once inserted, the 2.4GHz radio will come up with an SSID of tachyon-mgmt<last 3 octets of eth0 mac> and can be access with the passphrase 00000000 at 192.168.5.1.  Any clients will get a DHCP address within the 192.168.5.x range.
  2. Added significant throughput increases when data VLAN is enabled.  Non-data VLAN modes are also accelerated.


Known issues:

  1. Internal speed test results are not currently accurate on the 303L-65. [Fixed in beta-3]
  2. Site survey and temp channel change are currently not working for the 303L-65.  [Fixed in beta-3]
  3. Traffic control limits for the 303L-65 are not currently functional.  [Fixed in final]
  4. Ethernet status LED is not currently functioning on the 303L-65.  This will be addressed in the final firmware release. [Fixed in beta-4]
  5. PTP slave mode is not being set correctly internally.  A client configured as PTP slave will still connect to a PTP master, but it will not be optimized. This will be addressed in the final firmware release. [Fixed in beta-4]
  6. Some wireless peer stats are missing [Fixed in final]
