^the file which u need to have the wireless connection listed is /etc/network/interfaces .read "man interfaces" for more info.also,network-admin will be writing the config to this file for saving.so,while wireless is active,try System>admin>network to have ur config saved :)

no idea reg how to add wlan0 :? but a "auto wlan0"(dont do now!) with the respective options are the soltn.google for this.
if u have network-manager-gnome installed,it is supposed to auto-detect enable ur network devices!yes,do u have network-manager-gnome?else wait for someone with wireless network reply :)

From the interfaces file it looks that your Wifi card is eth1 and not wlan0. Which software do you use to manage the network? Network Manager?

I've had not-so-pleasant experiences with Network Manager, hence I use WICD. You may wanna try it out. Read here: *www.thinkdigit.com/forum/showthread.php?t=64555

why do you want it to be called as wlan? Any special reasons?
Intel wireless cards are detected as eth only.

Even with all settings given the wifi link goes down on its automatically.
sometimes the network key gets erased, sometimes the WPA type is set to WPA personnel from WPA2 personnel. sometimes the default route get sets to eth0 instead of eth1.

right now there is no fixed procedure to get the netowork up, sometimes i need to add the values & default route, some time restarting networking help, sometimes the wifi does not come up at all no matter how hard i try:x

I suppose u r using Ubuntu.
* Remove any entries that u might be havin in keyring.
* Try reinstalling the packages namely => wpasupplicant, network-manager-gnome, network-manager
* and then follow this guide.

Neways r u on Gutsy?

Hmmm, Gutsy supports out-of-box wireless. So it can possibly be a bug also. Try updating ur system!

Also it just clicked that u shud remove the eth1 entry from there i.e /etc/network/interfaces, clean the keyring and try again. It will ask for WPA-PSK pass!!
