OK, I've backported the iwn(4) driver for the Intel 4965 wireless chipset to 7-STABLE. You need both of: http://people.freebsd.org/~gavin/iwn-7/iwn-7.tgz http://people.freebsd.org/~gavin/iwn-7/iwn-7.diff Both are relative to /usr and are against 7-STABLE (although may well apply to 7.0-RELEASE cleanly). Please note that there are a couple of issues with this driver that aren't seen with the driver in -HEAD. Firstly, it only supports B/G channels, it doesn't work with 802.11a. Apparently this is due to a firmware issue which the driver in -HEAD works around, although I don't know how yet. Secondly, there may be a slight issue with regulatory domains. I'm not certain about this, but I was seeing issues while trying to associate to an access point on channel 13g, changing the AP to channel 1g fixes things. Even with those two caveats, I can say that so far in my testing it's been working very well. However, even if the driver works for you, I'm pretty sure it's too late for a merge before 7.1. Lastly, as the laptop is on loan to me and I'm going to have to give it back soon, I don't know if I'll have a chance to do any further work on this driver. I'm still interested in stories of success or otherwise. Thanks, Gavin
