I've been trying to set up an Ubuntu rig with a USB wireless adapter. I am getting some really high latency times, and it shows when SSH'ing into the rig. I'm not sure where to go as I don't see any errors, and I'm well within range of the AP. Trying the adapter in another machine works fine as well.

This is a headless system, using wpa_supplicant from the command line to handle the connection. What could I be doing wrong?
