# LTE Recovery Script for GL-XE300_V1.0 Router Board
|
|
|
|
This script resets and brings up a Quectel EP06-A LTE modem using `uqmi`.
|
|
|
|
## What It Does
|
|
|
|
- Kills stuck `uqmi` processes
|
|
- Stops the active PDP session (with timeout)
|
|
- Blanks and restores the APN
|
|
- Forces `raw_ip=Y` mode
|
|
- Brings interface down and up cleanly
|
|
- Confirms WAN is working (IP + route + ping)
|
|
|
|
## Why I Made This
|
|
|
|
Most LTE recovery tools are locked behind vendor-specific web GUIs.
|
|
This script is built for **OpenWRT 24.10.0** and is intended for users running **command-line only** with no GUI.
|
|
|
|
Use cases include:
|
|
|
|
- Deployments where modem control must be done over shell
|
|
- Cron-based or watchdog-based recovery without manual intervention
|
|
- Off-grid or solar-powered systems where the LTE radio is **only active at certain times of day**
|
|
|
|
If you're running raw OpenWRT and want reliable LTE recovery on CLI, this is for you.
|
|
|
|
## Requirements
|
|
|
|
System must be flashed to **OpenWRT 24.10.0** with the **Quectel EP06-A** modem installed.
|
|
Assumes modem interface is named `wwan` and located at `/dev/cdc-wdm0`.
|
|
|
|
The script uses an APN of `mobile`, which is valid for **EIOT Club SIM cards** as of this commit.
|
|
This SIM was selected for its plug-and-play compatibility with OpenWRT and `uqmi`, requiring no manual registration or configuration.
|
|
|
|
Assumes WAN port has internet access during the first run so the required packages can be installed.
