Tomato Firmware upgrade for Linksys WRT54GL Wireless router

Tomato is a small, lean and simple replacement firmware for Linksys' WRT54G/GL/GS, Buffalo WHR-G54S/WHR-HP-G54 and other Broadcom-based routers.
I flashed the clubs Linksys WRT54GL with new firmware, I used Tomato version 1.20: http://www.polarcloud.com/firmware I changed the gateway from 192.168.1.1 to 192.168.2.1 so I would have no conflict with my network or with any other wireless routers.

I also changed the SSID from the default Linksys to SPCUG for ease of access.
Tomato v1.20 allowed me to “boost” the transmit power and I set the “Afterburner” feature which is similar to “SpeedBooster” in the newer Linksys model’s.

I set the channel to 7 from the default 6 to lessen the chance of interfering with other wireless units.

The interface is much nicer and easier to use, it also has some nice graphs!
Here is some more info on Tomato: http://www.polarcloud.com/tomatofaq

Here are supported routers:

Linksys WRT54G/WRT54GS/WRT54GL's version
Look at the bottom side of the router to check for the version number, or compare the first 4 characters of the serial number with the following list:

CDF0/CDF1 = WRT54G v1.0
CDF2/CDF3 = WRT54G v1.1
CDF5 = WRT54G v2.0
CDF7 = WRT54G v2.2
CDF8 = WRT54G v3.0
CDF9 = WRT54G v3.1
CDFA = WRT54G v4.0
CGN0/CGN1 = WRT54GS v1.0
CGN2 = WRT54GS v1.1
CGN3 = WRT54GS v2.0
CGN4 = WRT54GS v2.1
CGN5 = WRT54GS v3.0
CGN6 = WRT54GS v4.0
CL7A = WRT54GL v1.0
CL7B = WRT54GL v1.1
CL7C = WRT54GL v1.1
CF7C = WRT54GL v1.1

If it's not listed above, and it's not a WRT54GL, it's not supported.
