You were right about it being a power issue. I turned off power management on my wireless and my signal quality remains high and my SSH connection is fast. Thanks!
Just a note, this did not work on the BBB: sudo iwconfig wlan0 power off I get "SET failed on device wlan0 ; Operation not permitted." So, a found a solution over at askubuntu<http://askubuntu.com/questions/85214/how-can-i-prevent-iwconfig-power-management-from-being-turned-on>, which was to create an empty wireless hook under /etc/pm/sleep.d by using this command. sudo touch /etc/pm/sleep.d/wireless Do that, then reboot, and wireless should remain high. I'm not sure if I need to worry about heat issues though. At the end of the day, this will be running a web server, so ideally I would want to write a script that keeps the power management on while no requests are coming in, and turns it off when they are. Thanks again!
