Are USB internet modems dangerous to use, with and without a router (DD-WRT)? I'm not sure if they're considered uPnP but I've read several articles on the danger of USB modems as they can bypass secure systems. Most new routers now have USB ports to plug in USB modems. Anybody have an idea of the dangers?
