Updating Cellular Module Firmware on Peplink Devices
Overview
Updating the cellular module firmware can resolve:
connectivity issues
carrier registration failures
SIM detection problems
modem instability
performance problems on specific carriers
This firmware is separate from the router firmware and updates the modem hardware module inside the router.
⚠️ Why an Alternate Connection is Required
The cellular module cannot be used and updated at the same time.
Because the update process requires an active internet connection AND disconnects the cellular modem during the update, it will NOT complete using cellular alone.
You must connect through:
WiFi as WAN Guide: CONNECT TO WIFI AS WAN
Ethernet WAN
a local network with internet access -LAN Cable to PepLink WAN port (if applicable)
Note: Loss of power during a modem update can permanently damage the modem. Do NOT unplug the device until the update completes.
