Edimax EW-7318USg and rt73 driver: no scan results...

GGhh · **Posted:** Sat Nov 03, 2007 4:11 pm

Hello everybody.

I (try to) use the driver rt73 provided by the rt2x00 project for my
Edimax EW-7318USg, wich has (I think) a Ralink rt2573 chipset.
http://www.edimax.com/en/produce_detail ... &pl2_id=44

I'm experiencing some problems; my wi-fi device is still not working.
I have a laptop Acer Aspire 5610. I use Debian Lenny, and my kernel version is

Code:

root:~# uname -a
Linux myMachine 2.6.21-2-686 #1 SMP Wed Jul 11 03:53:02 UTC 2007 i686 GNU/Linux

The problem is:
my usb wifi-card doesn't scan any cell, even if the Access Point is *just over my head*.

Here is a command line session in order to help you to help me.

The module is intalled:

Code:

root:~# lsmod | grep rt73
rt73                  189792  0 
firmware_class          9408  3 pcmcia,ipw3945,rt73
usbcore               123272  4 rt73,ehci_hcd,uhci_hcd

and is the right one:

Code:

root:~# depmod -a
root:~# modinfo rt73

The usb device is recognized:

Code:

Bus 002 Device 001: ID 0000:0000  
Bus 001 Device 001: ID 0000:0000  

and also iwconfig knows about it:

Code:

root:~# iwconfig wlan0
wlan0     RT73 WLAN  
          Link Quality:0  Signal level:0  Noise level:113

If I go very close to the access point, my intel centrino wi-fi
card can scan the cell (please note the level of the signal)

Code:

root:~# iwlist eth1 scan
eth1      Scan completed :
          Cell 01 - Address: 00:14:1B:61:10:A0
                    ESSID:"Unice-HotSpot"

                              11 Mb/s; 12 Mb/s; 18 Mb/s; 24 Mb/s; 36 Mb/s
                              48 Mb/s; 54 Mb/s
                    Quality=75/100  Signal level=-59 dBm  Noise level=-59 dBm
                    Extra: Last beacon: 24ms ago

but the Edimax usb card, sadly, doesn't see anything...

Code:

root:~# ifconfig wlan0 up
root:~# iwlist wlan0 scan
wlan0     No scan results

In fact, I'm not sure this is a rt73 problem;
maybe there is a daemon of my internal ip3945 intel wi-fi card that
causes some problems... I really don't know.

Anyway, all my network interfaces where switched off during the
execution of the above code.

Any hint?

Best regards,
Giovanni Gherdovich

Hello,
rt73 must be up when scanning.

Thankyou for replying.

I'm not sure to understand what "rt73 must be up" means.
before the scan I typed `ifconfig wlan0 up` so the intefarce is up.
I suppose that the module rt73 is loaded at boot time (it appear
whenever I ask `lsmod`).

Maybe a conflict with another module.
Try to look if the capability module is loaded.

Hello.

I don't have this module in my kernel:

Code:

root:~# lsmod | grep capability
root:~# 

Is the first time I heard about it (I've never worked with modules
before buying this laptop).
What is the capability module?
How can it help me?

Regards,
Giovanni Gherdovich

I don't know a lot of things about this module. It was present in a multimedia kernel I used last year. And when it was loaded, it was impossible to connect.

I would like to point out this appears to be the same problem I'm having with my rt73 on a power pc. But you're not using a power pc right? Just a regular intel or amd based pc?

Yes, I don't have a Power PC.
I have an Intel Centrino Core Duo system.

Ok, so I don't have this problem: that module is not in my kernel.

Have a look a this thread : http://rt2x00.serialmonkey.com/phpBB2/viewtopic.php?t=4402. kris313 posted an older version of the driver, which may work better. I've tried my rt73 stick yesterday and couldn't get it to work as well. I don't have the time to look into that issue right now however, I'm too busy with RutilT and school.

Thankyou Spy84464 for replying.

From your answer I start suspecting that there is some bugs in the
rt73-cvs-2007110217.
So befor trying to use the older version you suggest, I follow the procedure
described in the TESTING file.

Here the informations from the checklist you provided:
1. STEP TO REPRODUCE THE BUG
1.1 Install properly rt73-cvs-2007110217
1.2 Go very close to the acces point (i.e. 10 mt), in order to make sure that there is some signal to scan
1.3 Ask to my usb card to scan. It will scan nothing, i.e.:

Code:

root:~# ifconfig wlan0 up
root:~# iwconfig wlan0
Warning: Driver for device wlan0 has been compiled with version 22
of Wireless Extension, while this program supports up to version 20.
Some things may be broken...

wlan0     RT73 WLAN  ESSID:""  
          Mode:Managed  Frequency=2.412 GHz  Bit Rate=54 Mb/s   
          RTS thr:off   Fragment thr:off
          Encryption key:off
          Link Quality=0/100  Signal level:-121 dBm  Noise level:-115 dBm
          Rx invalid nwid:0  Rx invalid crypt:0  Rx invalid frag:0
          Tx excessive retries:0  Invalid misc:0   Missed beacon:0

root:~# iwlist wlan0 scan
Warning: Driver for device wlan0 has been compiled with version 22
of Wireless Extension, while this program supports up to version 20.
Some things may be broken...

wlan0     No scan results

2. THE CONTENT OF DEBUG FILES
is attached. I posted both /var/log/syslog and /var/log/debug

5. MY RT73 HW MANUFACTURER, MODEL AND REVISION
I'm sorry, but here I cannot help you. All what I know is that I own an
Edimax EW-7318USg , here is the link to the product:
http://www.edimax.com/en/produce_detail ... &pl2_id=44
but as usual they don't provide information about the chipset. If is so
important, I will send an e-mail to Edimax.

I hope this will help you to fix this bug, if there is any.
Let me say that I appreciate your work a lot.

Regards,
Giovanni Gherdovich

This was the winning move.
With the older version my device is now up and running.
Thanks a lot.
