Question Country code changing with Ralink rt73 chipset


I have a Sweex LW053 USB wifi dongle.
It has a Ralink rt73 chipset.
I have just compiled the kernel with rt73usb as module.

It works real fine... When it allows switching to the proper wifi channel.
Indeed, the dongle default is set to "country code" 1, and
permits only channels 1 to 11 (US setting) whereas France allows
only channels 10 to 13 -- suitable "country code" would be 3 or 5.

To draw the whole picture, I asked Sweex that answered they would
not help for Linux but provided sufficient information to make
sure the dongle may be switched (in Windows ME).

Changing channel of the wifi network is not an option.
Would anyone know how to change that country code setting in the dongle?

Question Sweex LW053


I'm sorry, but I can't help you with the country code. But I have a question for you. How did you configurated the LW053? I'm using a wireless pci card and that works great, but I never had the Wireless USB adapter running on my Slackware 11.

It is possible to change country codes using the iwpriv utility.

Thanks Michaelk,

I tried building up new wireless extensions.
The iwpriv gets me the following results :

wlan1 no private ioctls.

No better results with iwconfig while changing to channel 13:
> iwconfig wlan1 channel 13

gives me:

Error for wireless request "Set Frequency" (8B04) :
SET failed on device wlan1 ; Invalid argument.

Otherwise, (for Merciful), a regular configuration with iwconfig works fine:
> iwconfig wlan1 key ###your key here ###
> iwconfig nick ###your name on network###
> iwconfig essid ###your nework name###
> dhclient wlan1

This is for a wlan1 network interface with dhcp client.



code, rt73
