i4965 Finally Working (Albeit Insecurely)

Well I can finally toss my PCMCIA Aironet 352, and a good thing since the button was starting to stick. Even the thick single button design on the T-61 seems a bit flawed.

Components that worked for me
  • Linux 2.6.21.5
  • Linux wireless tools v 29 (compiled from source, obviously you need to wipe the one in your distro)
  • iwlwifi-4965-ucode-4.44.15.tgz
  • iwlwifi-0.0.38.tgz
  • mac80211-9.0.2.tgz
Here is an excerpt of my kernel config. The key breakthrough (I think) was that I read somewhere (probably on ThinkWiki) not to enable the wireless netlinks (CONFIG_NL80211 below) Otherwise the README's are pretty much on target. You do have to up the wlan0 interface before trying to assign the essid.

CONFIG_CFG80211=m
# CONFIG_NL80211 is not set
CONFIG_WIRELESS_EXT=y
CONFIG_MAC80211=m
# CONFIG_MAC80211_DEBUGFS is not set

# CONFIG_IEEE80211_DEBUG is not set
