Sierra Wireless Investigates Issue with 5G Band

Sierra Wireless, a Semtech company, released a statement late yesterday regarding an issue found on some AirLink devices. Take a look at the details below:

We are investigating an issue where MG90 5G single-radio North American and XR80/90 5G North American routers may experience permanent and irreversible connectivity issues on 5G band n41 used by T-Mobile and Rogers. For the complete details, refer to the Bulletin located on The Source here:

This bulletin provides steps that our customers using our 5G routers on T-Mobile and Rogers must take to ensure their routers remain operable until new firmware is released.

The details are:

  • 5G band n41 is used by T-Mobile and Rogers, therefore this issue only impacts 5G routers operating on T-Mobile and Rogers.
  • n41 may experience permanent and irreversible damage. The occurrence of the issue can be prevented by following the steps in the bulletin.

Please refer to the Bulletin for the details.

Corrective MGOS and AIRLINK OS firmware releases will be available in the May 2023 timeframe.

We will provide additional guidance when we have details to share about the upcoming MGOS/AIRLINK OS releases.

Is There An Upgrade Available for the Sierra Wireless MG90?

Sierra Wireless has just announced the General Availability of MGOS 4.4.2 for all AirLink MG90 4G and 5G routers. This is an important release that includes new features, security enhancements and fixes/improvements that address a number of field-reported issues.

Some of the highlights are:

  • Improved WAN-link policies(4G/5G)
  • AMM Multi-unit reboot
  • Enhanced VPN status broadcast
  • IKEv2 support for Cisco ASA

There are also some important notes to be aware of BEFORE you upgrade.

IMPORTANT NOTES

  • MG90 5G will only connect Verizon network in 4G
  • All customers running MGOS 4.4.0 must first upgrade to 4.4.1 (AMM OTA or via USB drive) before upgrading to MGOS 4.4.2. Failure to do so may prevent the router from connecting to the carrier network.
  • MGOS 4.4.1 can only be installed on the MG90 5G. Customers must not attempt to install MGOS 4.4.1 on the LTE-A & LTE-A Pro variants of MG90
  • If you upgraded directly from MGOS 4.4.0 to MGOS 4.4.2 and are experiencing networking connectivity issues, please contact Support for further instructions.

You may have noticed the 3rd bullet point above seems to leave those who own LTE-A & LTE-A Pro variants of the MG90 without an upgrade option. That is not the case thankfully. These users just require some additional steps, which we’ve outlined below:

  1. Get a USB 2.0 Flash Drive (it cannot be 3.0)
  2. Start up a 32bit computer 
  3. Download Win32 Disk Imager for Windows systems
  4. Use win32 disk imager to image the drive to the USB 2.0 
  5. Power off the router, then insert the USB and push the reset pin and insert power while you hold down the reset button for another 20 seconds. 
  6. Wait about 20 minutes for it to load
  7. Reboot the router and remove the USB

It is recommended that all MG90 customers upgrade to this latest release. For more information, please refer to the release notes available on the Source. You may also reach out to our team via phone, email, or chat!
