Greetings to all of you!
First of all, I would like to apologize that I am probably another one asking questions solved thousands times before. You are likely to tell me that I should use your search button. BUT - your search button actually doesn't allow me to search - says i'm not allowed to at this time -(

I used Google to search the posts and used all the information I could find but still I am not successful.

I am trying to set my Edimax EW-7318USg into master mode.

My System
Ubuntu 8.04.1
Kernel rt2x00 git

Linux a02-0435c 2.6.27-rc6-wl #2 SMP Thu Oct 23 14:42:25 CEST 2008 i686 GNU/Linux
[/code2axiep2s]

I downloaded and compiled hostap.git and configured it according to the ap-mode howto.

There is no additional info in syslog nor in debug.

Monitor mode works fine, Managed mode not tested yet, as I have no open AP near me. Scanning in Managed mode also works fine.

Thank you for any help!

I wonder if it's something I've said (

Well I don't have any experience with hostapd, but are you running the latest hostapd version (which includes nl80211 support?)
Also did you try the hostapd configurations posted in the other threads in this forum?

You have to change the hostapd driver to nl80211 (it uses hostap by default, which is suitable for Prism chipsets and won't work with Ralink). Of course, hostapd must be compiled with nl80211 support.


By the way, I also use this type of USB dongle with hostapd 0.6.6. The card itself works good in Ad-Hoc mode, but in Master (with hostapd), it is likely to hang for a minute after transmitting some data. It seems to happen only with some card/driver combinations on a station. So my question is, what is the current status of Master mode support in rt73usb? Should I expect such bugs?

There was also such an issue hostapd was like "did not acknowledge authentication response" all the time and rejected connections from two different stations. So I made it ignore these errors and then it started to work. Is this kind of error related to the driver?
