How to upgrade the firmware on a Linksys WRT 54GL Wireless G Broadband Router

Flashing the firmware on a router is risky. You may end up "bricking" your router even if you carefully follow intructions. If you brick your router, don't call us - there's nothing that can be done. The following instructions are for the Linksys WRT 54GL Wireless G Broadband Router.

By this time, you have downloaded the Less Networks firmware as a zip file. Open the zip file. There should be a single 2.4MB file containing the firmware inside: lessnetworks-v2-wrt54g.bin
On the Linksys WRT 54GL Wireless G Broadband Router, connect the port labeled "INTERNET" to any internet connection you have (DSL, cable modem, ethernet, etc.,). Power up the AP.
Connect your computer or laptop wirelessly or using one of the four wired ports to the AP. It should give you an IP address in the 192.168.1.0/24 range. Make sure that you can reach the internet and browse the web.
Direct your browser to "http://192.168.1.1". The factory default username and password for the Linksys WRT 54GL Wireless G Broadband Router are "admin" and "admin". You are now in the Linksys WRT 54GL Wireless G Broadband Router setup console.
Select "Administration" and then "Firmware Upgrade".
Click "Browse" and select the file containing the firmware that you downloaded previously.
Click "Upgrade" and wait for the process to complete (about one minute) and then for the Linksys WRT 54GL Wireless G Broadband Router to reboot (about another minute - finshed when the DMZ light turns off)
If you are connected wirelessly, look for the "LessNetworks" SSID and select it. You may need to "refresh your wireless networks" and/or "repair your connection" (renew your DHCP lease). You should receive an IP address in the 192.168.169.0/24 range.
Connect to "http://192.168.169.1" and enter the new password for the Linksys WRT 54GL Wireless G Broadband Router twice.
You are now connected to the Less Networks® SmartAP. Open Installation-and-Activation-Guide.pdf, a document that contains instructions to finish installation and customization.
