I tried to follow the 2 stickies about getting the wireless to work and what to do if it did’t. I eventually got stuck at some part in both and was unable to move on.
Before I had updated the linux kernel, the wireless was working perfectly fine right from installing opensuse 12.1. But I updated the kernel yesterday to 3.5.1 and now it doesn’t even try to connect using wireless.
I have an HP Pavilion dm4-2053ca laptop. It has an Intel Corporation Centrino Wireless-N 1030 (rev 34) Network Controller and the PCI Vendor/product ID Code is 8086:008b (rev 34).
Looking more at where I got stuck at on the stickies:
“Getting Your Wireless To Work”:
For this one, I got stuck at III. I could not find the boot.log they were referring to and the “dmesg | grep firmware” unsurprisingly returned nothing.
“My Wireless Doesn’t Work - a primer on what to do next”
Here, I got stuck on part 3 (looking through “dmesg | less”. I may have accidentally gone past the line I was looking for, but after going through it twice, I did not find anything that referred to anything about the network controller.
I hope this is enough info. Thanks for reading and thanks for any help that is provided.

With systemd, the info that was in /var/log/boot.msg is now included in
/var/log/messages.

If your wireless was working before, AND all you did was update the kernel, then
the firmware is likely OK.
Do you have a wlan0 created? You can check that with /usr/sbin/iwconfig. Your
device is driver by driver iwlwifi. Check that it is loaded with the command
‘lsmod | grep iwlwifi’.
Please post the dmesg output on some pastebin site, and post the link here.

There was nothing in the dmesg that refers to the wireless driver. I got it
wrong earlier - the driver is maned iwlagn. What does ‘modinfo iwlagn’ say? Do
you see a line something like

Did you build your own kernel, or where did you get it. The driver for iwlagn is
not present.
I used S.A.K.C. - SUSE Automated Kernel Compiler - Version 2.76 - Blogs - openSUSE Forums to compile and install kernel 3.5.1 from The Linux Kernel Archives . When i compiled the kernel, I used the standard/normal option to compile and install the kernel (not turbo). But my wifi was turned off at the time. And I read that when using the turbo option, it will only compile and install parts that are currently turned on or connected to the computer. I’m not sure if this was just an odd case where that happened.
Also, I still have the older kernel that I originally had. So if I need to recompile something from there or check something else out from that kernel, I can.

Those configuration parameters should be OK, and I do not understand why iwlagn
is not loaded. What does ‘lsmod | grep iwl’ show?
