Bash script to rename ssid when internet is not available for OpenWRT & Broadcom based DD-WRT

Rename offline Wi-Fi

If your internet connection is down, this script renames ssid to yourssid_OFFLINE. When internet is back, it removes postfix. Supports multiple ssids.

Supports

• OpenWrt routers (tested on 21.02)
• DD-WRT Broadcom based (tested on r44715)

For OpenWRT

• Copy the script to home dirrectory.
• Go to System/Scheduled tasks (http://192.168.1.1/cgi-bin/luci/admin/system/crontab )
• Set up a cron job to run script every 15 minutes.

For DD-WRT based on Broadcom

!!1! Currently in order to apply renaming, the script reboots the router. I'm looking for another way to apply settings

• If you have usb sick, copy the script there. If you don't, you need to enable JFFS storage. All other locations on DD-WRT are eraised each time router reboots. To do so, go to Administration/Management/JFFS2 Support Internal Flash Storage Enable .
• Copy script to the router via scp:

scp ~/rename_offline_wifi.sh root@192.168.1.1:/jffs/

• Go to Administration/Management http://192.168.1.1/Management.asp , enable Cron and add line
