D-Link DIR-615 E4 – install DD-WRT

D-Link DIR-615 E4 – install DD-WRT

The DIR-615 E4 features an “Emergency Room” which makes it easy to install alternative firmware (or re-install stock firmware). Unfortuantely the “ER” takes a chunk of the 4M flash. There are no recent standard builds of OpenWrt available. DD-WRT however works well and does exactly what I need it to.

I employ the DIR-615 as a client-bridge. It connects to a gateway over wireless. I can then connect other devices to the DIR-615’s ethernet switch.

This is my current method to load the recommended build of DD-WRT:

  1. Use an old browser to perform the flash eg. for Windows, Firefox ESR portable 10.0.11 available here:
    https://sourceforge.net/projects/portableapps/files/Mozilla%20Firefox%2C%20Portable%20Ed./Mozilla%20Firefox%20ESR%2C%20Portable%20Edition%2010.0.11/
  2. Connect PC to DIR-615. Change PC network interface to IP 192.168.0.2 /24 (ie.netmask 255.255.255.0).
  3. Type http://192.168.0.1/ in the browser address bar (do not connect yet).
  4. Hold reset button during DIR-615 power on. Continue to hold until orange power and globe leds flash orange. Connect to http://192.168.0.1/ , the “ER” is now available.
  5. Upload the dir615e4-factory-to-ddwrt-firmware.bin available here:
    https://download1.dd-wrt.com/dd-wrtv2/downloads/betas/2016/02-09-2016-r29059/dlink-dir615e4/dir615e4-factory-to-ddwrt-firmware.bin
  6. Re-configure network interface (eg. DHCP or 192.168.1.2 /24). The default web interface is http://192.168.1.1:80/ . N.B. this simplified process does not erase NVRAM so previously installed DD-WRT could have been configured differently and saved.
  7. Use the web interface to upgrade to the recommended build, currently:
