REWARD: 1 BTC if you can help me fix this today.

I have a used batch 2 avalon and I don't have the password. What is the easiest way to get it going? It's all set up with my info too, but it's not automatically connecting to my wireless and I can't login to change anything because I don't have the password. I've heard about resetting it by reflashing OpenWrt, but I don't see a reset button on the avalon and I don't want to mess it up. I also don't want to lose the system settings that have it overclocked, but I will if necessary.
