Title:
  rt73usb driver still buggy

Status in “linux” package in Ubuntu:
  Expired

Bug description:
  I can confirm, that the two different sticks I have with the same
  chipset, both fail in different machines, running 11.10 and now 12.04
  with 3.2.0-26 kernel. It loads the rt2x00usb, and does not yet use the
  hwcrypt option.

  WORKAROUND: Power Management: on

  The power option alone makes a difference:

  $ iwconfig wlan0 | grep Power
            Bit Rate=54 Mb/s   Tx-Power=20 dBm
            Power Management:off
  $ ping 192.168.116.200

  The signal strength is relatively weak,
  Link Quality=32/70  Signal level=-78 dBm
  though the 100-s of milliseconds at times to the access point are characteristic. The ping times are in average 10 times slower with power on.Needless to say that the sticks work perfectly okay in Windows.
