IMPORTANT: Cellular Firmware Update Recommended for Peplink -5GH routers on Verizon

[Giedrius]

We’d like to share an important recommendation for customers using Peplink routers with -5GH cellular modems on the Verizon network in US.

What’s happening?

Working together with Verizon’s Network team, we’ve identified that devices running older cellular module firmware are not properly negotiating 5G connections with the network as efficiently as they should. This can result in repeated connection setup failures on Verizon’s C-Band 5G sectors, which may impact both your device’s performance and the experience of other users connected to the same cell.

Who is affected?
Peplink routers with a -5GH (Sierra Wireless EM9191) cellular modem with Cellular Firmware version 03.09.06.00 or older.

What should I do?
Please update the cellular module firmware on your affected device. The upgrade can be performed through InControl 2 (guide) or via the device’s local web configuration page.

Need help?
If you have any questions or run into issues during the upgrade, please reach out to your Peplink partner or open a support ticket - we’re happy to help.

Thanks for your attention, and thank you for keeping your devices up to date It helps everyone stay connected reliably.

Thank you Andy for the catch !

For local configuration, you need to open support.cgi page.

If you are logging into the device locally you’ll see:
<IP_ADDRESS>/cgi-bin/MANGA/index.cgi
Then you need to change index.cgi to support.cgi as shown below:
<IP_ADDRESS>/cgi-bin/MANGA/support.cgi

This will open you a new page, where you can find option below. From there it should be straight forward

IMPORTANT: Before starting the update, we recommend confirming that a reliable secondary WAN connection is available. Also, please do not perform the update over a cellular connection.
