WLAN Radio Modem 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-76343/4/5/6 is used for operation in Wireless Local Area Networks (WLAN) according to the standard 802.11a/b/g/n. The usage of a 32-Bit ARM processor enhances the throughput performance. In addition to standard encryption according to WEP64/128 and TKIP/AES further security measures according to the 802.1x standard are available (WPA(2), EAP and more).
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.
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)

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:
Flowchart: Intermediate steps when updating to the latest firmware version
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.
