| You could buy a couple of routers and set them up with DD-WRT.  Link them together to be repeaters and you can have a huuge WAN with great coverage and strength.  I have no fucking clue how to do it but Redjake has it working perfectly so maybe he can provide some insight.  You can get the routers that support it for $30 each on the Internet.
