Re: [opensuse] Wireless LAN in BIOS disabled

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

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):

The funny thing is, that after I turned the netbook on again the wlan0 device
didn't show up in the logs anymore.

That was the first time this happened to me, it is just a bit weird to me.

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!
