You have to download the patch "allow-ap-vlan-mode.patch" that you can find at http://johannes.sipsolutions.net/patches/kernel/all/LATEST/ Then you have to install hostapd (version 0.6.3) with nl80211 driver (you can find all the informations that you need in the hostapd site). At the moment you can't enable master mode with iwconfig, you can do it only with hostapd. Now here is my problem: I have a BCM4306 (b43 driver) with kernel 2.6.25-rc9 and hostapd-0.6.3 installed. I tested the card performance with a simple test. The configuration of the network for the test was: an access point (my computer with BCM4306) and 2 clients (both using b43 driver). I used no encryption and work with 11M rate. I sent a CBR traffic (11M) from the 2 clients to the access point. When I started transmit packets from clients they disconnected from the AP until I didn't stop the transmission. Hostapd print this message that I've never seen before: _Failed to set beacon head/tail_ The problem is related to hostapd? Maybe when the AP processes a lot of traffic it was unable to generate beacons correctly? As the final goal of the experiment was to try 80211e performance, I tried the ad-hoc network mode, but I saw that the stations don't use qos support. Can I use qos with ad-hoc network? Thank you regards
