ipw2200 wifi card and wpa encryption (updated)
Firmware
Get firmware from http://ipw2200.sourceforge.net (v2.4)
and extract it to /lib/firmware/
Update:
i upgraded kernel to 2.6.17.6 and card it's not working anymore with firmware 2.4. You have to install FW 3.0 version to get it working again. Previously i was using kernel version 2.6.16.19.
Modules
load modules:
modprobe ieee80211 modprobe ipw2200and uncomment same lines in /etc/rc.d/rc.modules for automatic loading on startup. (thats for slackware based distros)
you can check now if modules are loaded ok by
dmesg | grep ipwyou should get something like this:
ipw2200: Intel(R) PRO/Wireless 2200/2915 Network Driver, git-1.0.8 ipw2200: Copyright(c) 2003-2005 Intel Corporation ipw2200: Detected Intel PRO/Wireless 2200BG Network Connectionfor enabling radio off/on switch add this to /etc/modprobe.conf
options ipw2200 led=1Configuration (wpa_supplicant is required)
/etc/wpa_supplicant.conf should look something like this:
ctrl_interface=/var/run/wpa_supplicant network={ ssid="wlan_name" scan_ssid=1 proto=WPA key_mgmt=WPA-PSK psk="password" }Usage
i hope you have your router setup with wpa encryption and dhcp.
in my case ipw2200 is on eth1
start
wpa_supplicant -B -i eth1 -c /etc/wpa_supplicant.conf -D wext dhcpcd -d eth1if everything is setup ok you should get an ip from dhcp server.
happy wireless surfing ;-)
Thanx a lot.
