[Bug 1022465] Re: rt73usb driver still buggy

  Thread Previous • Date Previous • • Thread Next 
udippel, as per http://us.msi.com/product/mb/A75MA-G55.html#/?div=BIOS
an update is available for your BIOS (2.0). If you update to this, does
it change anything?

If not, could you please both specify what happened, and provide the output of the following terminal command:
sudo dmidecode -s bios-version && sudo dmidecode -s bios-release-date

Please note your current BIOS is already in the Bug Description, so
posting this on the old BIOS would not be helpful.

Thank you for your understanding.

** Description changed:

- This has been going on for years, reported a number of times, eg.
- 773599, 812981 and quite some more. As far as I can see, mostly closed
- for lack of activity.  (Though the lack of activity was not so much on
- the side of the reporters.)
- 
- I can confirm, that two sticks that I have, two different sticks, with
- that same chipset, both fail in different machines, running 11.10 and
- now 12.04 with 3.2.0-26 kernel.
- 
- I don't say that this is all. It still load the rt2x00usb , which was
- also considered a culprit in some reports and workarounds, and does not
- yet use the hwcrypt option, but the power option alone makes a
- difference:

  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.
- Still, I don't say that this is *the* workaround. I gathered it from some other, unfortunately abandoned, bug reports with other work-arounds. Needless to say that the sticks work perfectly okay in Windows.

  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.
