Re: [CentOS] CentOS 7.2 laptop wireless Intel Corporation Centrino Wireless-N 2230 (rev c4)

[Andreas Benzler]

In my test cases with the new kernels 4.4.6 and others that i can not remind:

- iMac 2010 here  an at home no problems (Atheros)
- Standard Desktop WLAN PCI Card  no Problem
- Laptop with intel 3160N no problems…

and 7.0 3.10 works for the most of here.

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.

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.

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.

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.

Tony.

In my case they are both Dell E65xx fairly old but still serviceable.

E6500 has

Network controller: Intel Corporation Ultimate N WiFi Link 5300

E6510 has
Network controller: Intel Corporation Centrino Ultimate-N 6300 
(rev 35)

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.

yes iwl2030-firmware was already installed.

Please note, I reinstalled, because a virus named windows 8
spontaneously "repaired" the drive eliminating the dual-boot.
This time I configured wireless in the initial stage of installation
from DVD, it did connect. But after install, after reboot, it appears
not to be available.
Have not yet installed any extra packages.

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.

Re: [CentOS] CentOS 7.2 laptop wireless Intel Corporation Centrino Wireless-N 2230 (rev c4)

[Andreas Benzler]

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  and install with yum install 
kernel…rpm?

Sincerely

Andy

 suggests you might need to get a firmware tarball for that card, and copy 
 the appropriate iwlwifi-*.ucode file to /lib/firmware or something.

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?

 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

 does seem to interact with the wifi device.

Thanks Brandon and everyone -- to skip reboot I hope it is sufficient to execute

Thank you, I checked, and the firmware

is already installed by default (timestamped 2012-Jan, it is not new).

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.

Personal playground, those packages are unsigned!!!

http://centos.cms4all.org/centos/7/ 


noarch git firmware
kernel ml aufs - oh I was lazy


- Get Multimedia work, all my videos incl. DVD, midi and other audio files are 
working
  I was given up after test many repros.


libdrm 
radeon (no new iMac 2015…hmmm)
hardinfo


mutter - gnome 3 windows shadow hack
netatalk - apple time capsule on centos


Centos 7 live on usbdrive to test it on different machines….

Fun with Centos 7

PS:hm… gstreamer was working with centos 6 damm

 Don’t hammer my virtual server otherwise i push them away….

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.



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.
