Looks reasonably good (Atheros wireless, 4 MB RAM), with some problems
in limited areas.  Searching on 'fr-54rtr openwrt' finds this forum
thread.  Watch out for old posting dates, which could involve
now-obsolete branches of OpenWrt:


I see from about a year ago:


  Actually tried the backfire RC-3 code over the weekend. Appeared much
  more stable. Will try MTU if needed.

  I did appear to have a problem passing broadcast traffic too/from
  wireless <> LAN port daisy chained to my primary router.

  Basically, the 54RTR was just acting as an AP. No DHCP, etc. Hosts have
  no problem talking routed to Internet off BEFSR81, but can't pass
  broadcast traffic and thus can't find each other over netbios "browser"
  name resolution. Need to do more testing, but the same configuration
  works fine on the D-link firmware. Do I have to define an uplink or
  trunk port in OpenWRT or something to pass broadcasts or support
  multiple MAC addresses coming in on a LAN port?

 Host <wire> BEFSR81 <wire> FR-54RTR <wireless> Host
  The other potential use I have for these is as range extenders like the
  WRE54G type to routers not supporting WDS. Anybody got OpenWRT working
  as a extender/repeater to a non WDS router like the 2Wire ones?

  All the guides/posts I found are for OpenWRT-OpenWRT WDS configs.

It also seems like it would probably be _fantastically_ inexpensive at
Fry's.  A lot of places are talking about it being priced at $12!  
Hard to beat that, even as just a possible solution.

This post (from May, 2010) is on

  Basically, I just downloaded a copy of OpenWRT SVN trunk source code,
  configured using 'make menuconfig' to select packages/options I need,
  compiled using make, and then using the DLink GUI to flash the binary
  OpenWRT firmware file
  (openwrt-ar71xx-generic-dir-600-a1-squashfs-factory.bin). The subsequent
  upgrade can be done through telnet and/or ssh using sysupgrade utility
  with this OpenWRT firmware file:
  openwrt-ar71xx-generic-dir-600-a1-squashfs-sysupgrade.bin. Note: Lately,
  I notice OpenWRT seemed to have disabled RESET function on its firmware.
  So, if you have misconfigured your device while it is running on an
  OpenWRT firmware, there is no way to perform a factory reset to recover
  the unit unless you can have an access to its shell. This means you will
  need either to reflash it with an OpenWRT firmware through the DLink WEB
  GUI (requires pressing reset pin for about 20 seconds while the device
  is powering up) or use a serial-console cable to boot into its shell to
  make the necessary changes to recover the unit.

So, apparently, the files to get for OpenWrt 10.03 'backfire' (current
stable release) are in http://downloads.openwrt.org/backfire/10.03/ar71xx/
