Hi everybody
I've just installed Suse 10.0 and I've got a big problem.
My Acer Aspire 1694wlmi has two network cards: a Broadcom NetXtreme (ethernet) and a Intel PRO/Wireless 2200BG (wi-fi).
The first works properly, but the second doesn't.
Indeed, even if in yast that card is visible, there is no interface available.
I mean, the system recognizes the card as Intel PRO/Wireless 2200BG, but even if I try to activate the interface there is just eth0 (ethernet) and lo.
lspci finds my card, while ifconfig doesn't show any interface.
Does anyone know what is wrong?
Thank you.
Giuse
yes, and I have set it correctly.
The card does work ok in linux!! I used in mandriva, knoppix and debian....
I'll try with ifconfig -a...
But even if with an -a the card will be shown, how can I configure it? yast doesn't work....should I create an interface manually?
How are you trying to setup this interface? Is it on another subnet?
Does it have a corresponding config file in /etc/sysconfig/network/, such as /etc/sysconfig/network/ifcfg-wlan1?
Is the kernel module for this device, if different, loaded?
If so, and it isn't on the same subnet, can you use "sudo /sbin/rcnetwork restart wlan1"?
What messages are produced and what do you logs say after doing this?
note: I assumed the device is named wlan1.
Backing up a bit, could you explain why you use two wireless interfaces. If you want to use the second interface instead of the second, then first backup the ifcfg-wlan0 file somewhere, and delete the interface in YaST. ( Moving the ifcfg-wlan0 config file to root's home directory will have the same effect ). The YaST network interface GUI dialog is a convenient way to edit the /etc/sysconfig/network/ifcfg-* files. So I doubt there is a YaST problem.
If you intend to use both interfaces, they probably need to operate at different frequencies. Also if you are routing between two wireless networks, then they need to be using different subnets or network addresses. Otherwise you need to use a bridging device to operate with frames instead of packets. Something this exotic will go beyond what YaST is intended to setup. You can still set up the interfaces with YaST, but you will need to set up a bridge device and add needed firewall rule changes and probably study a how-to or two.
The output of the iwconfig, ifconfig and the ifcfg-wlan0 and ifcfg-wlan1 files may be illustrative also. ( Be sure to xxx out any key values in the ifcfg-* files. ) Also, use the wireless tools, such as "iwlist wlan1 scan" to verify that each of the two cards is functioning. That is a prerequisite.
Does it have a corresponding config file in /etc/sysconfig/network/, such as /etc/sysconfig/network/ifcfg-wlan1?
No. There is no file like that.

I don't know, but I think that should work....where can I see it? Ayways, if you mean the ipw2200 module, then yes, it is loaded.

You don't understand: I don't have any wlan0, wlan1 or similar. This is my problem: I have a card and no interface!!!

Wait, I never said I use two wi-fi interfaces. I have two interfaces, but only one is wi-fi.....the other one works properly as eth0.

I can't do anything of that! I have no interface to refer those commands..... ifconfig and iwconfig see just 2 interfaces: lo and eth0. In I type ifconfig -a, then is shown another interface, sit0, with IPv6-in-IPv4 as Link encap....
If the Intel wireless device doesn't show up in yast, or ifconfig then you probably don't have a kernel module for it installed. There is an Intel sponsored driver available on Sourceforge: http://ipw2200.sourceforge.net/
