http://downloads.openwrt.org/whiterussian/rc5/bin/
openwrt-wrtsl54gs-jffs2.bin
To install the firmware, follow the same preparation and setup procedure from the previous
chapter. You can use either flash.sh from Chapter 14 or the Linksys web interface as in
Figure 15-2. The SL by default comes up on 192.168.1.1 like OpenWrt so you can browse
directly to it. After the firmware is programmed, the router will reboot, the browser page will
automatically refresh, and you’ll be presented with the familiar OpenWrt home page.

FIGURE 15-2: Uploading OpenWrt firmware

When you have OpenWrt running, go through the same steps to get it configured as a wireless
client and install the serial drivers. The configuration is the same; it’s one of the benefits of
using OpenWrt. The USB driver is different, so instead use the kmod-usb-ohci package and
run insmod usb-ohci. Otherwise, the only difference is when typing df -h or running top;
you’ll notice you have more disk space and memory.
