^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

gary4gar · 08-01-2008, 08:13 PM

Code:

~$ cat /etc/network/interfaces 
auto lo
iface lo inet loopback


iface eth1 inet static
address 192.168.1.4
netmask 255.255.255.0

auto eth1

praka123 · 08-01-2008, 08:19 PM

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

during the time,look:

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: http://www.thinkdigit.com/forum/showthread.php?t=64555

mehulved · 09-01-2008, 12:14 AM

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

apacheman · 09-01-2008, 03:09 AM

wifi or wlan same thing

Yes, my broadcom wireless was detected as eth when using it with ndiswrapper

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

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?

infra_red_dude · 09-01-2008, 12:05 PM

Did you try WICD?

gary4gar · 09-01-2008, 12:58 PM

yes i am using gutsy.
i even tried, making my network open(without any key), still it does not work

mediator · 09-01-2008, 01:05 PM

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!!
