Following Lew's earlier identical recommendation, I bought the
WRT54GL and upgraded the firmware. The procedure is unclear in
the downloadable documentation. At first I thought I bricked the
device, but using TFTP I was able to unbrick it and proceed. Here is
the process I experienced.
Upgrade successful; wait 5 minutes before clicking Continue [forgot!]
Hard reset (30-30-30)
- Disconnect all UTP cables
- Push reset button for 30 seconds
- Without releasing reset button, disconnect power cord
- Hold reset button for another 30 seconds
- Repower
- Continue to depress reset button for another 30 seconds
- Release reset button and give router 10 seconds to resettle
- Disconnect power cord for 10 seconds and reconnect
All default settings should now be effective
Now I am setting up WDS connecting the WRT54GL to a D-Link G-570S. For a clueless
novitiate like myself it takes a lot of fiddling with settings (literally days in my case) to get
the
devices to work as desired. I have finally got them talking and transparently extending the
router's DHCP assignments via WDS (on my lab bench only).
Antennas: at one end I have a Cantenna and the other a 5 db gain antenna with a home-made
parabola. This should work with good signal strength out to several hundred feet. We'll know
Wednesday!
For the parabolic reflector:
parabola.zip Program to calculate parabolic curve for antenna
parabola_vb6_sourcecode.zip includes libraries if necessary

Good luck. Send more questions as needed.
