This router is an Annex B version of D-Link DSL-524T.

→D-Link DSL-5xxT and DSL-G6xxT - ADAM2 Installation Guide

The installation procedure is almost the same as for D-Link DSL-524T, so use the link above for the full installation procedure. The main differences are:

• Both username and password for ADAM2 bootloader are adam2, not ADAM2. The bootloader of my device listens by default on port 5.8.8.8 at startup.
• Flashing router on Linux (kernel 2.6.35-24) was EXTREMELY slow. (Put “debug” command before “put …” command during installation procedure and you may see.) I tried Windows 7 Home edition, but a connection error appeared. At last, FTP client in Windows XP Professional did the job - it took only about 3 minutes to put the firmware on the router. So I recommend you to use this OS, but I hope that it is an issue of my device or someone will find another way to do a sucessful flash.

I use Backfire 10.03.1-rc4 and it works like a charm – it's uptime is in weeks. My unit has been modified by adding heatsinks on chips.

If you use generic firmware “openwrt-ar7-squashfs.bin”, you may have to add Annex B support to it - it contains only Annex A module. However, it is very easy to do this job: find a package with “kmod-sangam-atm-annex-b” in its name in /package subdirectory of the release you have used. On your router, remove original “kmod-sangam-atm-annex-a” package (using opkg or web interface) and activate dropbear-sshd - telnet into your router and insert new root password using passwd command. Then put “annex-b” package to your router by scp and install it using opkg.

You may compile your own firmware with Annex B support or use Imagebuilder tool, too.

Edit your /etc/config/network using this stub:
