Wireless is naturally slower than wired, I recommend running through ethernet, especially since you're close anyways. If you can't then it's not the biggest deal, but you'll see instant and obvious improvements w/ games.
To help out your search for some answers, OP, I'll say this:
I've been at around 50-60 s/r when out on my own in the wilderness, and then 60s and 200-600r when at camps or in cities.
I usually stay around yellow-green, sometimes spiking into red
So long as you are near your wireless router (within 30 feet, line of sight), your wireless connection will be faster than any internet connection you would have coming into your house. 802.11n is 70-160Mbps. Wired is 100 or 1000 Mbps. However, cable modems have a theoretical
max of 30Mbps, with most people lucky to see 6Mbps in real use. Unless you have a real spotty wireless connection, there is no effective difference between wired and wireless networking at this point when accessing the internet.
