Thanks much for the suggestion! I'm going to try (already ordered) a powerline ethernet adapter, as that will also work for my situation. Unfortunately, I paid a bit more than the product you linked, but shouldn't be an issue cuz Eth is going to the moon, right?

I know you already ordered the powerline thing, but you could also get a really cheap linksys router or other that is compatible with ddwrt firmware. You flash the right firmware on it and set it as a wireless repeater/bridge. then you have better wifi signal. plus plug in an ethernet wire into it to your rig
