http://pobletewireless.blogspot.com/2006/05/monta-un-conector-sma-reverse-en-tu.html Add a SMA-R connector to your WRT54G
- Note: the author of that page used ordinary hookup wire, which would cause impedence mismatch and reduced performance or even hardware damage. The proper way is to use coax cable of the proper impedence. Better yet, remove the original connector so it doesn't act as a "stub" to the RF signal. - star882

3. Software
- Networking
WRTbwlog A tool that shows internet traffic on all wired and wireless interfaces, as well as many other useful and related functions. (WRTbwlog doesn't count traffic in OpenWRT, because it uses "find -mtime -1", but "find" from OpenWRT WhiteRussian RC6 doesn't support "-mtime")
BandwithTestPage - A simple CGI script for testing the instantaneous bandwidth to the wireless router. Just drop into /www/cgi-bin and chmod+x.
- System
- Wireless
WiViz - A very nice wireless network visualization tool ||
