Any ideas why my wlan0 device disapeared? No way to answer that with just this amount of data, however do the following: 1.) Look for the i2l3945 in /etc/modprobe.conf. 2.) Do 'lsmod |grep iwl3945' Is the driver loaded? If not, modprobe it. 3.) Do an iwconfig. Is the wlan0 device there and does it show wireless extensions? Does it show a reasonably strong radio signal? Is the essid correct? etc., etc ... 4.) Does the wlan0 device have an ip address? Do 'ifconfig wlan0' to find out. Does some other device, something other than localhost, have an address? Perhaps your wired connection? 5.) Is dhclient running? Do 'pidof dhclient' to find out. 6.) Do you have a route? Do 'route' to find out. If not, you can add a route with: route add default gw xxx.xxx.xxx.xxx wlan0 All of the above is implicated in making a successful wireless connection, and this is just on the Fedora side. iPlease note it is also possible the problem is on your dhcp server or wap device. The files involved in automating all of this in Fedora are /etc/sysconfig/network and /etc/sysconfig/network-scripts/ifcfg-*. Output acquired via dhclient is cached in /var/lib/dhclient.
