Bug description:
  Hi. The connection with this device is fast and stable, but seems to
  drop after a certain amount of data has been transmitted. The easiest
  way to reproduce it is to download something large. I can always
  reproduce it by downloading a torrent. After about 300-400MB, it seems
  like the wireless dongle hangs and the connection doesn't work
  anymore.

  At this point, network commands such as iwconfig freeze, and it's also
  impossible to reboot or turn off the computer. However, if the
  wireless dongle is unplugged and plugged again, everything's back to
  normal.

  The module is set with nohwcrypt=1. If this option is not set, the
  connection drops much faster. Also, I've noticed that the latency is
  lower with nohwcrypt=1 (using speedtest.net, the latency without
  hardware encryption is consistently 3 times less).
