X-Spam-Score: 0.0 (/) X-Spam-Report: _SUMMARY_ Message-ID: 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. Firmware V 4.30.7 Flashed December 6, 2008 per and and e-mail from Rosenthal 8Oct08 FAILED View Hard reset fails Download from Use TFTP to flash C:\TEMP>tftp -i 192.168.1.1 PUT code.bin Transfer successful: 2941952 bytes in 12 seconds, 245162 bytes/s New firmware 4.30.12 build 3, Dec. 20, 2007 Flashed December 20, 2008 with (2.8 mb) from (Tested OK from ) 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 Successful; Then flashed [checked hash] from Use procedure at 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 Details at Good luck. Send more questions as needed.
