Hi again, I've now checked the latest compat-wireless snapshot (2009-10-21) and it has the same problem: Windows based clients with 11g or 11b cards cannot connect to a mac80211/ath9k/hostapd based AP. It used to work with compat-wireless-2009-06-02. I've tried an Intel PRO Wireless 3945ABG card and an older 3Com 3CRWE62092B card. The Intel card seems to accept the auth response but chokes on the assoc response while the 3Com card ignores the auth response and just sends auth request indefinitely. This time I used hostapd 0.6.9 in all tests. All the non-windows 11g clients I've tried all work (an iPhone and a Google Dev G1). I only have access to one 11n capable windows based client (Ralink noname card) but that one works just fine and connects to the AP on the first attempt. Any ideas on how to track this down? I can enable some logs and hack together some patches to track this down, I'm just not sure where to start. Bisecting is difficult for me as I can only build compat-wireless and only on OpenWrt... Thanx for any help in advance. /Björn 2009/10/20 Björn Smedman <bjorn.smedman@xxxxxxxxxxx>: > Hi all, > > I'm trying to update from compat-wireless-2009-06-02 to > compat-wireless-2.6.32-rc1.
