An alternative might be the TP-link TL-WR703N: a wireless router available on ebay for about $30 delivered.
It has a MIPS CPU, has built in 802.11b/g/n, 1 ethernet port, a USB port, and runs at low power off a USB jack (5V). It can be flashed with Linux but you have to navigate chinese menus to do so (not hard).
