  Saw the following in the logs :

  When I first wake the computer, or boot the computer, wireless
  attempts to connect about 15-20 times before finally connecting.

  Once connected, speed and latency vary randomly, but mostly on the
  slow/high side respectively.

  When I test my connection speed with a site like speedtest.net, I'll
  usually get full speed for about 1/2 a sec , then it goes to zero for
  awhile, then comes back on at full speed a second later or so.

  With windows, connected to the same router, none of these problems
  occur.

  WORKAROUND: sudo iwconfig wlan0 power off
