If you’ve found an ecwifi.txt file, here’s how to interpret its contents. The format varies by source, but most follow a similar pattern.
Using scripts to scrape ecwifi.txt from hundreds of APs allows you to:
WiFi debugging at verbose levels can fill storage. Rotate the file using logrotate on Linux or set a maximum size:
# In /etc/logrotate.d/wifi
/var/log/ecwifi.txt
size 10M
rotate 3
compress

Where can you actually find ecwifi.txt? Depending on the device and its state, the file can reside in several locations:
| Device / Environment | Typical Path | Access Method |
|----------------------|--------------|----------------|
| Ruckus ZoneDirector | /tmp/ecwifi.txt | SSH or SCP as admin |
| Boot partition of an AP | /mnt/flash/ecwifi.txt | Serial console or TFTP |
| Factory reset recovery | ecwifi.txt on USB drive (if recovery enabled) | Physical USB stick |
| Firmware BIN extract | Inside the root squashfs | binwalk or unsquashfs |
To access it on a live AP, you would typically SSH into the device and run commands like:
show tech-support
cat /tmp/ecwifi.txt
Many vendors bundle ecwifi.txt inside a larger support.tar.gz archive.
