Title:
  wifi woefully poor connection speeds

Status in bcmwl package in Ubuntu:
  Confirmed

Bug description:
  wifi woefully poor connection speeds (6Mbps - 70Mbps - flakey at the
  top end)when compared to windows 270-300Mbps, slow but steady. I've
  even resorted to attempting to use ndiswrapper which loads the drivers
  and even appears to get the card going, however despite wpa_supplicant
  installed and everything set up ok, the connections to my routers fail
  (they negotiate wpa fine). So back to trying to get these bcmwl kernel
  drivers working again.  I got the card on a quick Google search for a
  wifi AC card with linux support. I saw broadcom had drivers for it, so
  I bought it a few months ago. Its been a pain ever since.

  Anyway, per https://help.ubuntu.com/community/WifiDocs/Driver/bcm43xx

  There is some data attached to this bug report I'm sure, however to assist I'll post the extra terminal content and some of the ndiswrapper stuff as it might help as a comparison:
