 * 1) Configure your computer's local lan ethernet address to 192.168.1.7, subnet 255.255.255.0, gateway 192.168.1.1 . Then connect an Ethernet cable to your computer and port 1 of your router. (Do Not Use Wireless)(Nothing else connected to router)
 * 2) Perform a Hard reset or 30/30/30.
 * 3) Open your browser to http://192.168.1.1.
 * 4) Use the firmware upgrade dialog to flash Vxworkskiller-G2V13.bin.
 * 5) WAIT for at least five minutes before you continue! (longer is better) Give vxworks killer plenty of time to do its magic!
 * 6) You will not be able to browse the WRT54G2V13 at this point, but you should be able to ping 192.168.1.1. If the router doesn't reply you haven't set your computer's network settings correctly (on step 1)
 * 7) Tftp the DD-WRT firmware to the router, use latest dd-wrt.v24_micro_generic.bin from the folder where you got these instructions; after sucessful tftp, wait 5 min for the router to finish writing new nvram deafults, etc... It should reboot on its own at least 2 times, so give it 5 min and then go to http://192.168.1.1 (If it not reboot on its own, wait another 2 min, and then power cycle it), you should see the password reset page. Don't worry about changing it at this point.
 * 8) Perform a Hard reset or 30/30/30.
 * 9) WAIT for at least 5 minutes before you continue! (longer is better) Give the router plenty of time to to boot.
 * 10) Browse 192.168.1.1, you should see the password reset page, change it! Then configure.
 * 11) Check for recommended builds here.
