12V connected to DC to AC inverter ( http://www.amazon.com/gp/product/B000WGYNAA) to power your DSL modem and a Linksys WRT54G variant (http://en.wikipedia.org/wiki/Linksys_WRT54G_series) that has been flashed with one of the Linux distros like http://openwrt.org or http://www.sveasoft.com for the WRT54Gs. Most of these inverters will plug into your car/truck of course. Hope this helps! John
