funny thing is, during installation all is fine and centOS is connecting successfully to wireless.

After reboot nothing of that is left - no wireless in network-manager.. as if it has never existed.. so weird

During installation, does it list what the wireless device in use is? The strange thing is this RTL8188. It's showing that but not the Intel Centrino, do you have two wireless cards or just the one?

Yes it showed that. Thought I'm being clever so I captured everything I could during installation.

I didnt install any hardware device. Just the processor has been upgraded.

So you're saying it should work?

Yeah, well, the wlp*** isn't really the device name, it's a unique identifier for each wireless card on an individual system. So you say the processor has been upgraded, do you happen to remember if there were two wireless cards in there when you did that (assuming you were the one who did it)? For that matter, where are you getting the Centrino info from? And also, is there Windows on this laptop? If so, and you know how to get the device IDs from Windows, please post the ID and the name of the card as Windows describes it.

a store did the processor upgrade .. but why should they install/remove a wireless adapter? Think there always was only one wireless card built in. The info about the Centrino I got from some W530-info sites.
For example:

Before the upgrade I had windows 7 on this laptop. Then I tested kubuntu. Wireless did work without problem.

Yeah. I don't think you still have a Centrino. I think you have a Realtek card now. I'll look into this tomorrow and get back to you.

A major difference between those lspci outputs is that CentOS sees the power management capabilities. Follow Lord_Lizard's instructions here to check the PM state.

tried that .. indeed I can see

parm: swenc:Set to 1 for software crypto (default 0)
(bool)
parm: ips:Set to 0 to not use link power save (default 1)
(bool)
parm: swlps:Set to 1 to use SW control power save (default 0)
(bool)
parm: fwlps:Set to 1 to use FW control power save (default 1)
(bool)
parm: debug:Set debug level (0-5) (default 0) (int)

tried to change that as described, making a file in "/etc/modprobe.d/rtl8192ce.conf"

But after reboot the above didnt change.. and no wireless.

Tried also to find systool .. but theres no package available. I dont have that command

Did you force ips and fwlps to 0?

In that file
/etc/modprobe.d/rtl8192ce.conf"
I wrote:
options rtl8192ce swenc=0 fwlps=0 swlps=0

Thought ips is already at 0.. Maybe thats the mistake?

Maybe. You could try it, but I'm not sure that will help still. I'm not real into wireless, and I'm not super-knowledgeable about it, so I hope someone else better suited can do more. Remember, though, that RTL81xx chips aren't great under Linux.
