Re: [Bug 1022465] Re: rt73usb driver still buggy
I am very sorry, I updated maybe a hundred BIOS before, always without any
problem (meaning, I know how to!). But when I had to update the BIOS of
this mainboard last time, I ended up with a brick. And then it was a costly
€ 30 expenditure to return to factory, and some 10 days without. I reckon
it was an MSI problem (since I joined the ranks of many more people bitten
likewise); and promised to myself never to try upgrading *this* mainboard
again.
So sorry,
Uwe

Title:
rt73usb driver still buggy
Status in “linux” package in Ubuntu:
Incomplete
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

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.
