[-- Attachment #1 --] Hi all, I'm attempting to backport the iwn(4) driver for the Intel 4965 driver from -HEAD to RELENG_7 and am getting stuck with it at one particular point: WPA authentication times out. I've so far tried to both take the -HEAD driver and de-vapify etc. it, and also to take a pre-vap version of the driver and bring in required changes. Both fail in exactly the same way, with authentication timing out. I have verified that the laptop can successfully connect to the same network with -HEAD and the same wpa_supplicant.conf file. I've attached the log file from wpa_supplicant. Code can be found at http://people.freebsd.org/~gavin/iwn/ - I'm currently working with the updated-from-pre-vap version so that's the one that generated the log file and is probably the best to look at. Sadly I don't have the infrastructure at the moment to test if the driver works with WEP. Any help or pointers would be greatfully received, Thanks!
