LCOS („LANCOM Operating System“) is the operating system for all Wireless LAN Access Points and Routers. In the context of the hardware given by the products the at a time latest LCOS version is available for all LANCOM products and is available free of charge for dowload from LANCOM Systems.
This document describes the innovations within LCOS software release 8.00, as well as the changes since release 7.82
Warning Hint – Backing up the current configuration
Before upgrading the firmware to LCOS 8.00 it is essential to backup the configuration of your router. Due to extensive features it is not possible to downgrade to a previous firmware without using the backup configuration.
Please see the reference manual for instructions on how to backup the router configuration.
If you want to upgrade devices which are only accessible via router connections or WLAN bridges, please keep in mind to upgrade the remote device first and the local device afterwards.
Note when updating Central Site Components
We strongly recommend updating productive systems only after internal tests in client environment. Despite intense internal and external quality assurance procedures possibly not all risks can be eliminated by LANCOM Systems.
Note when using managed Access Points
Prior to managing a LANCOM accesspoint using a WLAN controller, you have to upgrade your access point with the latest converter. The corresponding converter file can be found in your device’s download directory on the LANCOM homepage. The converter upload is similar to a firmware upgrade.
Note when using certificates
Prior to loading certificates into the LANCOM you must install the current converter. The appropriate converter file can be found in your device’s download directory on the LANCOM homepage. Flashing the converter file works similar to a firmware upgrade.
Note when using converter firmwares
You will need enough free memory to use a firmware 6.0 and newer in your LANCOM 15x1, 1611+, 821+ and DSL/I-10+, as well as for LCOS 8.0 in a LANCOM XAC.
Due to the implementation of several new features within the current build of the firmware, it is no longer possible to store two main firmware versions side by side. To gain more free space for the current version, it is now necessary to upload a converter firmware into your device. The converter-firmware has a much smaller size, so that it is now possible to store the main release of the firmware besides the converter-firmware.
This setup is only necessary once for a single device and is done with the so-called converter-firmware (see readme.pdf of the affected devices).
After having flashed the converter-firmware the firmsave function of the LANCOM device is available only on a limited scale. The update to a newer firmware is furthermore possible. However, in case of an update failure the LANCOM will only work with a minimal-firmware which allows just local access to the device. Any extended functionality, in particular remote administration, is not possible when running the minimal-firmware.
Note on Dynamic VPN registration
By reason of patent you have to register the functionality „Dynamic VPN“ with IP address transmission over ISDN. This operating mode is usually required when you configure a VPN tunnel with dynamic IP addresses on both sides without dynamic DNS services.
Any other Dynamic VPN operation mode (e.g. transmitting the IP address via ICMP, provoking a callback etc.) does not require registration.
The registration process is fully anonymous - no personal or company data will be transmitted.
The registration of the Dynamic VPN option requires administrator rights on the LANCOM device.
Registration with LANconfig
When scanning the device (e.g. right after program start) LANconfig automatically recognizes devices which have to be activated. After confirming the arising hint LANconfig automatically transmits solely the device’s serial number to the LANCOM Systems registration server. The registration code is automatically transmitted back, thus the option will be activated. The state of this procedure is visible in LANconfig.
Registration with WEBconfig
For the registration with WEBconfig the serial number of the device is required. You can find this information on the bottom of your device.
Using WEBconfig you will find a link on the first page which leads you to the LANCOM Systems registration server. Here you must enter your device’s serial number and -optional- your e-mail address. After transmitting the data you will receive a registration code for the option.
To load this code into your device, please proceed as follows:
Log in to the device with administrator rights. Select “Enable Software Option”, which is placed on the entry page. On the following page enter the registration code and confirm by selecting “Apply”.
Remarks regarding the usage of VoIP options
VoIP options for LANCOM 1821 Wireless ADSL are dicontinued with LCOS 7.20. The final version containing the VoIP Call Manager is LCOS 6.32.
As from LCOS 7.5x support for VoIP options for the devices LANCOM 1511 Wireless DSL and 1521 Wireless ADSL is discontinued. The final version containing the VoIP Call Manager is LCOS 7.30.
For the „VoIP ready“ routers LANCOM 1711 VPN, 1721 VPN and 1811 Wireless DSL support for the subsequently installed VoIP option will be discontinued with LCOS version 7.56. If you want to continue using your VoIP option, please do only use LCOS versions up to and including 7.54.
For T-Systems Business LAN R800+ VoIP functionality is discontinued in LCOS 7.60
LCOS 7.70 is the final version supporting VoIP options for the remaining „VoIP ready“ devices.
Remark for device specific support of the current LCOS version
LCOS 8.00 does no longer support the following devices:
- LANCOM 1511 Wireless
- LANCOM 1521 ADSL Wireless
- LANCOM 821 ADSL/ISDN
- LANCOM 1610 VPN
- LANCOM 1611 Office
- LANCOM 1620 VPN

If you want to upgrade the firmware of your device to a new version, please install the latest LANtools first. Before running the firmware-upload you should save the router configuration to a file. After that you can use LANconfig to load the latest LCOS-version into the device.
In principle, we suggest upgrading the firmware of your device only if you are in need of the latest features.
Please note that different firmware files might be available for your device. Further information can be found in the file README.PDF in the download area of our homepage.
