I was in Seattle about a week ago. Here’s the post. I just went for the day so I didn’t get to see much. But I did see the Space Needle, Pikes Place Market, and the waterfall garden. When I got to Seattle I took the Light Link Rail from the airport to Downtown Seattle. It cost 2.50 for a round trip ticket.
Here is a tutorial on how to flash dd-wrt on to the TP-LINK TL-WR1043ND. Although this guide is meant for a specific type of router it should be fairly similar to any router compatible with dd-wrt.
