Credits go to Steve from the Gl.iNet Discord for origionaly creating these scripts.
Network-Diag-Utilities is a lightweight collection of shell scripts designed for network diagnostics, troubleshooting, and performance benchmarking on Linux-based systems (particularly OpenWrt, Debian, or other embedded platforms). Whether you’re validating VPN throughput, testing router WiFi performance, or measuring bufferbloat, these tools help you quickly collect reliable data.
- iPerf3 test wrappers – simplified commands to benchmark throughput, upload/download, reverse tests.
- Bufferbloat script – tests MTU fragmentation, checks for latency under load.
- Network path analysis – tools to run traceroute, mtr, latency jitter checks.
- Router/Client automation – deploy these scripts on embedded devices like GL.iNet, OpenWrt routers for consistent workflows.
- Minimal dependencies – built for environments with BusyBox or limited space.
| Script | Description |
|---|---|
bufferbloat-test.sh |
Detects MTU issues and fragmentation, logs packet size where performance drops. |
iperf3-client.sh |
Runs iPerf3 download/upload tests, gathers results for reporting. |
mtr-latency.sh |
Conducts MTR/traceroute sessions and logs latency + hops for network path diagnosis. |
router-deploy.sh |
Automates deployment of diagnostics on GL.iNet/OpenWrt router environments. |
- Linux or embedded system (Debian, OpenWrt, etc.)
