Persisting Ralink 5392 Wireless driver issues

[chili555]

Let's troubleshoot rt2800pci.

dmesg | grep rt2
iwconfig
sudo iwlist wlan0 scan  <-or whatever iwconfig says your interface is, if not wlan0
rfkill list all

jgomez2@SJ:~/Desktop$ dmesg | grep rt2
[   15.546747] phy0 -> rt2800_init_eeprom: Error - Invalid RF chipset 0x5392 detected.
[   15.546797] phy0 -> rt2x00lib_probe_dev: Error - Failed to allocate device.

jgomez2@SJ:~/Desktop$ iwconfig
eth0      no wireless extensions.

lo        no wireless extensions.

phy0 -> rt2800_init_eeprom: Error - Invalid RF chipset 0x5392 detected.

That's very weird because the driver does include your device:

$ modinfo rt2800pci | grep 5392
alias:          pci:v00001814d00005392sv*sd*bc*sc*i*

The driver was patched some time ago to add your device: http://www.spinics.net/lists/linux-w.../msg90992.html

Let's build the compat-wireless suite and see if we can fix this. Hook up the ethernet temporarily and do:

wget http://www.orbit-lab.org/kernel/compat-wireless-3-stable/v3.5/compat-wireless-3.5.4-1.tar.bz2
tar -xvjf compat-wireless-3.5.4-1.tar.bz2
cd compat-wireless-3.5.4-1
./scripts/driver-select rt2x00
make
sudo make install
sudo modprobe -r rt2800pci
sudo modprobe rt2800pci

Any improvement?

[jgomez2]

Nothing has changed that I can see. I cant dis/enable wireless.

[chili555]

That's a stubborn wireless device you have there! Let's have a look at:

sudo modprobe rt2800pci
dmesg | grep rt2
modinfo rt2800pci | grep 5392

Thanks.

Dont thank me, Im the cause of your ongoing war against this WLAN card

Let's double-check the integrity of the required firmware:

md5sum /lib/firmware/rt2860.bin

Here is what I get:

75a1da3caa0b1c95e81dfba207f834c6  /lib/firmware/rt2860.bin

If the driver is not defective and the firmware is not defective, then I wonder if the device may be defective. Does it work in other computers and operating systems?

[jgomez2]

jgomez2@SJ:~/Desktop$ md5sum /lib/firmware/rt2860.bin
75a1da3caa0b1c95e81dfba207f834c6  /lib/firmware/rt2860.bin

The device works when I boot up windows.

The device works when I boot up windows.

We may try the Windows driver, then. May I see:

lspci -nn | grep 0280

Thanks.
