These instructions are for the WRT54gS version v.5 and v.6. NOTE THE S. The instructions for the router Wrt54g WITHOUT the S are above.

IN SPITE OF SOME OTHER INSTRUCTIONS ELSEWHERE, YOU REALLY NEED TO CREATE A CUSTOM VX Image for your router. If you don’t you will get a generic mac address on your router and a generic mac address will mean most ISP won’t let you connect to the internet. Here is how to do it properly

When it says to power cycle, below, this means to unplug the power from your router, count to ten, and plug the power back in.

  3. Set a static IP on your computer to 192.168.1.7
