[opensuse] Wireless LAN in BIOS disabled
hi I use KDE 4.4 and openSUSE 11.2 on an eee PC netbook. Yesterday I suspended yesterday the netbook to RAM and turned it after two hours or so on again and then my wlan0 device was gone. Later I found out that it was disabled in the BIOS and after I enabled it again it worked. Does anyone have an idea how that could be, that it disables Wireless in the BIOS just by suspending the computer to RAM? I also checked the NetworkManager logs and they didn't show anything special except this few lines (this is from the moment when I suspended the computer to RAM): Mar 23 20:28:09 NetworkManager: <info> (wlan0): now unmanaged Mar 23 20:28:09 NetworkManager: <info> (wlan0): device state change: 8 -> 1 (reason 36) Mar 23 20:28:09 NetworkManager: <info> (wlan0): deactivating device (reason: 36).

Mar 23 20:28:11 NetworkManager: <info> Sleeping... The funny thing is, that after I turned the netbook on again the wlan0 device didn't show up in the logs anymore.

Oh now this is interesting! I too have found that my wlan0 device on my laptop has stopped mysteriously on me a few times! Rebooting (even with a power cycle) back into SuSE11.2 would not restore it, nor would an rcnetwork restart. I don't use the NetworkManager BTW, rather I have stuck with the old ifup, ifdown routine. I kinda figure it might be a hardware failure at first. But then each time I have rebooted my laptop to Windoz XP and did a diagnostic and repair on my networks, I would find my wlan0 device working again! So far that has been my solution, but now you have made me suspicious of SuSE... Definitely weird! Marc... -- Marc Chamberlin www.marcchamberlin.com A man said unto the universe - "Sir I Exist!"

Marc, what brand/model is your laptop? My Dell Inspiron has been giving me a similar problem and it turns out the wireless switch is the culprit. It uses Fn+F2 to turn it on/off. For some reason, sometimes when the laptop is shutdown the wireless gets turned off. Then nothing but Fn+F2 will turn it back on. You can check it by booting in windows and see if it will fire up the wireless. In my case it wouldnt without doing the Fn key stuff. BTW, it has happened after an update/reboot.

But the thing with my laptop is, that there is as far as I know no key for disabling the wireless LAN. It just happened after setting the computer to standby. Sebastian -- To unsubscribe, e-mail: opensuse+unsubscribe@opensuse.org For additional commands, e-mail: opensuse+help@opensuse.org

Sebastian, does your bios have a way of disabling the wireless? Obviously Windows knows how to activate it so there must be something there. I found on a Toshiba there was a switch which was very small and in an out of the way place. 2 people missed that one! Have you tried using iwconfig? man iwconfig will give you info on txpower. It is a method for enabling and disabling the radio and enabling/disabling the power control if they are available.

Yes, there is a way to turn the wireless off in the BIOS, but I haven't seen any buttons yet with could turn it off. There are 4 buttons which are under Linux pretty useless and actually I don't know what they are for, but none of them turns off the wireless.
Have you tried using iwconfig? man iwconfig will give you info on txpower. It is a method for enabling and disabling the radio and enabling/disabling the power control if they are available. Yes, I tried iwconfig, but not with txpower and there was no wlan0 device. The only place where I found that my card was still there was under YaST Network Settings, but there it also wasn't able to search for any routers or so.

Sebastian, wlan0 is the designation on my laptop for the wireless card. Do iwconfig or ifconfig and see what your wireless is named, then do the iwconfig thing. Richard -- To unsubscribe, e-mail: opensuse+unsubscribe@opensuse.org For additional commands, e-mail: opensuse+help@opensuse.org

Richard, Sebastian - My laptop is an HP Pavilion dv9000. There is a slide switch on the front edge of the laptop to turn on/off the wireless network. I always double check it, even turn it off and on to make sure. As I said, rebooting to Windoz has always been my fix, somehow that seems to get it going again...

Uh I should have said rebooting to Windoz and doing a network diagnose and repair has been my fix.. Marc.. -- Marc Chamberlin www.marcchamberlin.com A man said unto the universe - "Sir I Exist!" "However" replied the universe "I do not see where that creates in me a sense of an obligation" S Crane.

Marc, you may be one of the lucky ones. I googled the problem and found that some users could only get the wireless enabled by the temp switch to windows. Occasionally i've had to do that as there's no indicator of the switch actuation in openSUSE. Of course it could be your provider. We're at a campground and the wifi disconnects randomly. A rcnetwork restart will usually get it back, but not always. Richard -- To unsubscribe, e-mail: opensuse+unsubscribe@opensuse.org For additional commands, e-mail: opensuse+help@opensuse.org
