RT73 Master mode issue

Today I acquired a Linksys WUSB56GC, it's an rt73 device. I think everything is working correctly (haven't got any APs nearby to test), except for one thing. I can't get it into master mode.

[root@Arch /home/tim] iwconfig wlan0 mode master
Error for wireless request "Set Mode" (8B06) :
SET failed on device wlan0 ; Invalid argument.

As I want to use this USB dongle to let my Nintendo DS connect to the internet, it's kind of a big problem for me.

I'm running Arch Linux, 32 bit, kernel 2.6.21.

Is this a hardware or a driver issue, and if it's a driver issue, will it be fixed someday?

Thanks in advance,

Tim Theijsmeijer

A quick search about master mode on this forum (or reading the FAQ) would undoubtly have answered your question.
But since search buttons and faq are there to be ignored

master mode is not supported for the legacy drivers
master mode is supported when using rt2x00

And to answer the next question you will likely ask

rt2x00 including master mode support is only available by using GIT,
if you look on the website (or use the infamous "search" button on this forum) you will find the instructions on how to work with git.

The rt2x00 git tree means downloading an entire kernel tree,
and there is no alternative at this time if you want master mode support.

Well actually, I did read the FAQ and I searched the forums. No need to get all worked up, it was just a misunderstanding. I thought I was already using the non-legacy driver... but I guess I'm not.

Anyway, thanks for the fast reply, I'll try that stuff first thing tomorrow.

I'm running in to the same problem, with the same error message as above. I'm using a D-Link DWL-G122 USB (H/W version C1) device with an rt73 chipset, and the drivers from the linux kernel, which I understand to be the new drivers (not the legacy ones). Monitor mode works fine, master mode doesn't.

Can anybody help me out?

That is still the wrong version, only rt2x00.git supports master mode since you need a patched mac80211 version.
After that, you need hostapd with nl80211 support to get the interface into master mode.
