With CentOS 7.2 a laptop wireless card is recognized in dmesg, but nonfunctional. Toggling the hardware wifi switch causes the Bluetooth icon to appear and disappear. The network configuration window shows the Wireless tab greyed out. Rebooting with the bluetooth enabled does not help. It appears the appropriate driver is iwlwifi, which is what works in Fedora and appears to be available and installed in CentOS.
lspci gives 08:00.0 Network controller: Intel Corporation Centrino Wireless-N 2230 (rev c4)
1. How do I get this working? I am happy to work with command line tools.
2. Are there other packages I need? I installed wireless-tools, and tried to fiddle with iwconfig and NetworkManager to no avail. iwconfig does seem to interact with the wifi device.
3. Is there documentation I should be following to understand/troubleshoot networking support? https://wiki.centos.org/HowTos/Laptops/Wireless does not document the iwlwifi driver.

suggests you might need to get a firmware tarball for that card, and copy the appropriate iwlwifi-*.ucode file to /lib/firmware or something.
Hallo don’t know if this helps.

Hello Philip,
In my test cases on Centos 6 or 7 I always run an elrepo kernel or build my own one from rewritten spec file. That helps me out to get Centos work as good it can be.

Hi John, Thank you, elrepo sounds good to know about -- http://elrepo.org/tiki/About says is an extra repository for hardware support. Still not clear how to troubleshoot the problem so I know what to install from elrepo.
I know that a spec file is involved in creating an RPM file; do you mean that you make your own kernel RPM?

Good morning Philip,
- To install a most vanilla kernel elrepo is a quick step look forward about kernel solution - Yes build own kernel by a special kernel specification for your machine. Why not? - Frozen a kernel in fact „it works“ with the right firmware for your wifi is a good solution.
I got a mixed network with Windows 3.11 up to Windows 10 and Linux with OpenSuse, Ubuntu and a HPC Centos 7 Cluster on Opteron 6380.
By the way, when you get a preinstalled System on a laptop it works in most cases from prebuilder.
It’s a common thing to use the given driver. To upgrade it all the time by update can hold you back todo you real work.
As hardware, network and software specialist i try out different compositions. My private iMac 2010 not run really on the 2.6 - Centos 6 or 3.10 kernel form Centos 7. Same effect on newer hardware from „today“.
To build the right kernel for specific hardware is for me a common thing. Freeze it when i got - also.
We froze the HPC cluster at 7.1.503, because it works for us. To update or upgrade can not be done all the time, our calculations run from hours to month….
Some of you say Centos 7.0 works why not download this kernel from vault.centos.org http://vault.centos.org/ and install with yum install kernel…rpm?
Sincerely
Andy

CentOS 7.0 works when installed but when you upgrade it to 7.2 the wifi device stops being recognised.
I'm going to do an install later today of 7.2 and see how it goes.

OK I installed 7.2 ( 7-1511 Development workstation )
Anaconda allowed me to configure the wifi and it got an IP address from the router. So the wifi is working.
Reboot and no wireless device recognised.
NetworkManager only offers a wired and network proxy options for configuration.
iwl2000/2030 are installed and rfkill says the wireless is neither hard nor soft blocked.
So any ideas.

My workaround.
On the Dell E6500
installed CentOS 7.0 from DVD ( development workstation ) wifi works
updated to CentOS 7.1 ( 7.1503 ) using vault.centos.org wifi works
updated to CentOS 7.2 ( 7.1511 ) using local repo wifi works
So I ended up with a working 7.2.
Hope this helps someone.

Is NetworkManager-wifi installed? I remember after I installed Centos first time (7.0) wifi worked. When I later did a reinstall (7.2) during installation wifi worked fine, but after a reboot not. Seems NetworkManager-wifi did not get installed by default.

Anecdotal evidence only so take with a pinch of salt ;-)
I installed 7.0 on a Dell laptop E6500 wifi worked.
I logged on remotely to do the update to 7.2 ( 7.1511 ) and at the same time I was pinging the laptop from another terminal. This should give me some idea of when wifi stopped working.
When the wifi stopped working, the pings stopped, in the update window the cleanup after the install was taking place and had stopped at cleanup of wpa-supplicant. Don't know what significance of that is.
Tony
Hm, but let me drop a note:
I’m on a *most* clean installation of 7.2 and other wifi it works.
I Installed the „Gnome Desktop“ who give me the graphical network manager, but with another network card for sure.

Is NetworkManager-wifi installed? I remember after I installed Centos first time (7.0) wifi worked. When I later did a reinstall (7.2) during installation wifi worked fine, but after a reboot not. Seems NetworkManager-wifi did not get installed by default.

I may have missed this but what model laptop are we talking about?

Anecdotal evidence only so take with a pinch of salt ;-)
I installed 7.0 on a Dell laptop E6500 wifi worked.
I logged on remotely to do the update to 7.2 ( 7.1511 ) and at the same time I was pinging the laptop from another terminal. This should give me some idea of when wifi stopped working.
When the wifi stopped working, the pings stopped, in the update window the cleanup after the install was taking place and had stopped at cleanup of wpa-supplicant. Don't know what significance of that is.

Thank you, I checked, and the firmware
/usr/lib/firmware/iwlwifi-2030-6.ucode
is already installed by default (timestamped 2012-Jan, it is not new).

How do I get this working? I am happy to work with command line tools.
Are there other packages I need? I installed wireless-tools, and
tried to fiddle with iwconfig and NetworkManager to no avail. iwconfig does seem to interact with the wifi device.
- Is there documentation I should be following to
understand/troubleshoot networking support? https://wiki.centos.org/HowTos/Laptops/Wireless does not document the iwlwifi driver.
https://wireless.wiki.kernel.org/en/users/drivers/iwlwifi
suggests you might need to get a firmware tarball for that card, and copy the appropriate iwlwifi-*.ucode file to /lib/firmware or something.

Could you post the output of:

Could you post the output of dmesg | grep iwlwifi
Thanks Brandon and everyone -- to skip reboot I hope it is sufficient to execute sudo grep iwlwifi [CentOSpartition]/var/log/messages (you can see several reboots and my attempts to experiment)

Partial solution.

take a view on:
kernel and linux firmware sometimes firmware is excluded after upgrade to new revision.
