OK, I've backported the iwn(4) driver for the Intel 4965 wireless
chipset to 7-STABLE.
You need both of:
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
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.
