	~~To use an external filesystem like~~ a ~~USB thumbdrive with our OpenWrt~~ system, ~~we'll want~~ to ~~add some~~ software ~~to tell~~ OpenWrt how to use a USB drive~~. That~~'~~s because to make OpenWrt small enough to fit on a tiny battery-powered router's firmware, you~~ have to ~~make OpenWrt pretty stupid~~.		The stock router has only 640 KB of free space, but we can stretch out by using a 64 GB jump drive to store the file system.

			However, to get OpenWrt to fit into 640 KB of space, no software is included that tells OpenWrt how to use a USB drive, so we'll have to install some modules.

	But before we can install modules, we have to connect OpenWrt to the internet.		But before we can install modules, we have to connect OpenWrt to the internet.
