Other times I see the previous behaviour that I reported 1+ months ago. The AssocReq frame to the ap is rejected; it appears the ral sta side does not ACK the Auth response frame from the ap so it then rejects the AssocReq. Specifically I see retransmits of the Auth response from the ap until the AssocReq comes from the sta at which time the ap sends a Deauth. I also see ProbeResp frames from the ap being retransmitted which also indicates failure to ACK by the sta. In the one case where I was able to associate I could transfer data ok so I'm guessing you've still got setup issues prior to association and/or the handling of management frames. If you want a packet trace let me know. Otherwise I see problems when ejecting a ral cardbus card. It appears the driver doesn't recognize when a card has gone away when scanning; e.g. you'll see lots of msgs of the form: ral0: could not write to RF until there's a timeout (device timeout) followed by ral0: could not read from BBP ral0: could not write to BBP At some point LONG time past I see ral0: detached; but sometimes not until I insert another card. The above issues happen with both my ral cards (Asus WL-107g and Zonet ZEW1501). All this is with CURRENT of today. Sam
