[Bug 638791] Re: old and faulty rt2870sta

[Asbjørn Gabrielsen]

  Hi

I have now tested the ISO image, by doing a fresh install on my 
computer. At first the device appears to work fine. It connects, with 
WPA encryption, and it stays connected. This is an improvement from lucid.

However, there is a problem with speed. The connection is slow. I have 
100% signal strength and network information says I'm connected at 
54Mbps, but browsing is slow. I have double checked my connection, both 
with cable and by plugging the wifi dongle into my other computer 
(running lucid with my self-compiled driver). It must be the driver 
that's the problem.

When running lsmod | grep "rt2", I get this
asbjoern at ubuntucat:~$ sudo lsmod | grep "rt2"rt2800usb               
9955  0
rt2800lib              31970  1 rt2800usb
rt2x00usb              11316  2 rt2800usb,rt2800lib
rt2x00lib              31575  2 rt2800lib,rt2x00usb
led_class               3393  1 rt2x00lib
mac80211              266657  2 rt2x00usb,rt2x00lib
cfg80211              170293  2 rt2x00lib,mac80211
crc_ccitt               1699  1 rt2800usb

The output shows that the device use the rt2800usb driver, instead of 
the rt2870sta. When I blacklist this driver, the device doesn't work at 
all. As far as I can understand, there's still something wrong in the 
device list(s).

I have run the apport-collect command from your e-mail below.

When I install the latest upstream kernel and boot with that, i get an 
error message and the computer boots to a command prompt instead of 
gnome. I get no further.

Refer to https://wiki.ubuntu.com/KernelMainlineBuilds .  Once you've tested the upstream kernel, please remove the 'needs-upstream-testing' tag.  This can be done by clicking on the yellow pencil icon next to the tag located at the bottom of the bug description and deleting the 'needs-upstream-testing' text.  Please let us know your results.
