Hello All,
I am a newbie here and until yesterday night wireless was working fine on openSUSE 11.2 After a reboot, suddenly wireless is not even shown as a possible network medium. In the network manager, the tab with “wireless” is greyed out.
After going through many forum posts, here is what all I have tried.Output from various commands:
modprobe iwl3945
WARNING: Error inserting iwlcore (/lib/modules/2.6.31.5-0.1-desktop/updates/drivers/net/wireless/iwlwifi/iwlcore.ko): Unknown symbol in module, or unknown parameter (see dmesg)
FATAL: Error inserting iwl3945 (/lib/modules/2.6.31.5-0.1-desktop/updates/drivers/net/wireless/iwlwifi/iwl3945.ko): Unknown symbol in module, or unknown parameter (see dmesg)
iwlist scan
lo Interface doesn't support scanning.
eth0 Interface doesn't support scanning.
irda0 Interface doesn't support scanning.
pan0 Interface doesn't support scanning.
iwconfig
lo no wireless extensions.
eth0 no wireless extensions.
irda0 no wireless extensions.
pan0 no wireless extensions.
In hardware information list in yast, I was able to see Wireless LAN entry. When I expanded + I was able to see a huge list of different values and all. One interesting enrty within the list was as follows:
Drivers
Active: No
modprobe: Yes
modules
modprobe iwl3945
I guess that driver is not getting loaded since modprobe is giving an error which I mentioned earlier. What could be reason? Did driver crashed? Since this issue cropped up only after I rebooted the machine. How to fix this? How to install the driver if I have?
Not that I know of. How to check if I am using any repo’s beyond default? and how to roll back? Excuse me if my question is dumb,but I am a newbie here
I also rebooted after doing “zypper dup”.
Wireless status remains same as before the outpur of modprobe, iwlist scan and iwconfig is still the same as what i posted in the first post.

My wireless was working just fine until yesterday night…it was just that i rebooted it and it was gone :\
I’m guessing now, but I would assume you need to rebuild the driver module in the kernel.
Re-installing the kernel might do it, but I doubt it.
You need someone wiser than me on this.
Thats what I did and it made it work. Still am confused as to why it stopped working at the first instance. I hope it keeps working like this. For sure installing it over and over again is not an option. As a end user I must say that Suse has to travel more distance before it can catch up with Ubuntu in terms of hardware support and stuff, but personally I like SUSe and i hope that it improves further

It is unfortunate, but openSUSE 11.2 was released with 2 serious bugs in
networking - one in setting the routing, and the second in DNS. Both have now
been fixed. AFAICT, these bugs showed up in the middle of the test series and
only affected users when there was a complete reinstallation. For me, that
happened after I decided that 11.2 was usable, and started upgrading, not
reinstalling. Of course, the users most affected are those coming to openSUSE
for the first time.
Now that your system is working, it should remain so.
It’s good you have managed to repair it. At least the DVD is good for that.
Sorry I wasn’t more help.
Funny thing, just noting lwfinger’s comments, but I have experienced no such issues. Sure I have seen others with them, but for me, luckily, 11.2 is darn near perfect.
The “problem” here had nothing to do with the bugs mentioned by Larry but with broken compat-wireless packages being automatically installed after adding a repo without having a look what’s actually inside it (I suspect enzokiel’s repo in this case).
Simply uninstalling any “compat-wireless” packages (and adding a lock for them, read man zypper on this) would have done the trick.
Still, if users do not read what will be installed after adding repos without any consideration what (unstable) software might be inside them and run into such problems, they get what they deserve.
