I am editing the first post because this thread has become a tech assistance thread. Please scroll down to see my questions regarding getting my 'new' (used) WRt54G V 1.0 up and running. DIAG is blinking, so I must upgrade formware. I can't connect to the net through the router. Downloaded the upgrade but can't get it 'into' the router - all procedured for upgrading the router seem to involve connecting to the net through it!! See below, please. Any help is appreciated. As you will see, I have been trying on my own, not just asking someone to solve my problem for me, and I am not a computer guy at all. Please scroll down to the 10th post in this thread, it's where the trouble starts.
