Okay, for example I get my internet from linksys, model WRT54G. The box is in my basement, it is how I get my internet to my computer. It is a wireless box found physically in your house somewhere. If you find the box that is your key to hosting. Some brands for you to look for are linksys, netgear, and 2wire. It will have brand and model written on it.
Don't give up! If you find the box I'm pretty sure I can get you to host, but it's up to you.
