This article provides essential updates for Zyxel's 5G NR series devices, including the NR5101, NR7101,NR7102, NR5103 and NR2101, NR2101. We highly recommend utilizing the latest updates for your device, as these updates address numerous known issues and vulnerabilities. Installing the updates is a straightforward process and can effectively resolve concerns related to signal quality, device stability, unexpected crashes, and unscheduled reboots. Furthermore, these updates address issues related to SIM card detection and other challenges associated with provider settings. Please make sure that performance and security is maintained by quickly applying the latest updates to your Zyxel 5G NR series device.
Disclaimer! This article offers a general overview of the series and may not apply uniformly to every model, software/firmware version. Prior to purchasing or using the device, please consult the model/version-specific documentation or reach out to technical support for accurate information.
Note: To access Voice over LTE (VoLTE) features offered by ISPs for making calls over LTE/4G. Due to the complexity of VoLTE configurations, Zyxel firmware does not support VoLTE. Since each provider has unique VoLTE configurations, it is best to purchase Zyxel equipment from your provider. As a workaround, you can configure the LTE router for 3G only to enable VoLTE, but this will not work in regions such as Germany, where 3G is unavailable.
Note: Not every firmware may work in every country. You can refer to the "digits", i.e. "AAYE", if your current firmware on the device matches this article to install a new one. It could also happen that you already have a newer firmware on your device as available within this article. If you need any assistance, please get in touch with our Support Team!
Note: We recommend avoiding LTE (radio) module firmware updates unless necessary, as they can sometimes reduce device performance. LTE (radio) is often tailored to specific regions and network settings. If your device is stable, updating the device firmware only, not the LTE module, is sufficient.
The module firmware names indicate both the version to be installed and the one to which you can upgrade. All updates must be installed sequentially, following the correct order, one by one.
