hi,
I have Lenovo G550 and openSUSE 11.4. Everything’s ok, wifi without problems, I could connect to anywhere I wanted to, but yesterday while laptop was running and was connected actually by wire to internet, after removing the wire I realized that I cannot connect to wifi (the laptop was hibernated during night) - even the light diode in the front of the laptop was not shining. I went to yast and realized that the wlan0 isn’t enabled and there’s new eth1 port. But the wlan by ifup I cannot start and the eth1 I cannot start as well.
I didn’t find there if someone has the same problem.
What can I do? I’ll copy there any output just say me please what you need.
thanks

Similar thing here with a sony laptop. I seem to loose wifi randomly and I
cannot enable it again although I can enable the networking checkbox, I
can’t do the same with the. wireless.
I have to kill the Knetworkmanager (ctrl+Esc, then choose from list) and run
it again from the kde menu.
I have no idea what it might be, but it is very annoying.
Cheers

I have a similar issue on my Sony Vaio (VGN-NW320F) with an Atheros AR9285 PCI-Express wifi interface. I don’t kill and restart KNetworkManager though (though I’m sure that would “fix” it) but simply issue an “ifconfig wlan0 down” command and then issue an “ifconfig wlan0 up” command and it works again for a while. I haven’t really dug very deep on this but I figured I’d chime in to say you guys aren’t the only ones.
My uname -a returns:
Linux xxx.ersatz.net 2.6.37.1-1.2-desktop #1 SMP PREEMPT 2011-02-21 10:34:10 +0100 i686 i686 i386 GNU/Linux
I ran a tail -f of /var/log/NetworkManager to see if anything showed up in there that might help me out but I haven’t seen anything come by yet.
It’s interesting - I can trigger the issue by simply copying a large file over wireless from another host. If I figure anything out I’ll post back here.
