Western Digital MyNet N600 OpenWRT support

After starting the wiki page on the WD N600 about 3 months ago, and posting about it in the OpenWRT forums, I’m proud to announce that OpenWRT is now supported on the WD N600.

I installed the luci web interface, configured it up and installed some basic tools, and the following is still available:

Filesystem                Size      Used Available Use% Mounted on
rootfs                   12.5M      1.2M     11.3M   9% /
/dev/root                 1.8M      1.8M         0 100% /rom
tmpfs                    61.7M    880.0K     60.9M   1% /tmp
/dev/mtdblock7           12.5M      1.2M     11.3M   9% /overlay

tmpfs                   512.0K         0    512.0K   0% /dev

Its quite a capable CPU:

See the wiki page for installation instructions!

EDIT: It seems there are some issues with previous builds that can cause wifi to drop out after periods of time. I’ve built r38259 of OpenWRT Barrier Breaker (trunk) that in theory is patched to stop this from happening. Testing is still ongoing and feedback is appreciated…
