WLAN Radio Modem
HG G-76343 / HG G-76344 / HG G-76345 / HG G-76346

for 802.11 a/b/g/n networks (version for 802.11 ac) / Serial / Ethernet / USB / Version with LTE/5G

The Client Adapter HG G-76343/4/5 is a wireless LAN adapter (in Götting documents the terms radio modem respectively WLAN client are used synonymously) that connects devices via Ethernet, USB or serial port to wireless networks conforming to the 802.11 a/b/g/n standard. The radio modem connects all devices that are connected to its LAN interface to a network reachable via WLAN.

Via a serial interface the radio modem can receive and transmit data that is sent or received by a communication partner connected to the network (WLAN or LAN). This communication partner can also be a radio modem or a computer that sends resp. receives via a matching application.

Variants

The radio modem is available in different variants. The differences are the casing and the number of available interfaces. All variants can use the firmware file and can be configured with the MC-Config program attached at the bottom of this page. You can find a detailed variant overview in the data sheet attached below. The variants are:

HG G-76343 (1x serial / 1x LAN)
HG G-76344 (1x serial / 2x LAN), also available as a version with either Public LTE (4G), Private LTE or 5G, s. data sheet HG G-76344-A LTE in the downloads
HG G-76345 (no serial / 4x LAN)

Security Notes

Starting with Firmware 2.11b a fix is included for the vulnerability issue known under the name KRACK (“Key Reinstallation Attack”) in the security standard WPA2.
Firmware 2.12r and higher include security related updates, for more info see the complete Changelog. The firmware 2.12w1 has a new kernel that closes the security gap that became public under the keyword “FragAttacks”.
Firmware 2.14: All firmware versions of line 2.14 contain security relevant updates related to line 2.14, see also complete Changelog. Those still using firmware 2.12x do not need to update to 2.14 for security reasons. Those who have any version of 2.14 installed must keep it up to date.

Open Source Compliance Information

The firmware of the radio modems described on this page includes software code developed by third parties under the GNU General Public License (“GPL”) or GNU Lesser General Public License (“LGPL”). More information about the terms of use and how to access the GPL code and LGPL code used in this product can be found on our Open Source page.

Firmware Update Notes

To get to the latest firmware version intermediate steps are necessary that depend on the firmware version currently installed on a device. If this procedure is not followed, the radio modem could become unusable and must be sent in for repair afterwards. The intermediate steps are shown in the following diagram:

The following applies:

After loading a new firmware into a radio modem, this new firmware must run for 2-3 minutes before performing the next step. In no case a reset must be triggered nor may the power supply be disconnected during this time.
If the MC Config program is used for the update, always the latest version of this program must be used (available via the downloads below).
It is recommended – especially for major version upgrades – to save the configuration of the radio modem as a file. This can be done e.g. with the MC Config program: Select device > Config key > Save to File.
