yes iwl2030-firmware was already installed.
i have since installed wireless-tools and wavemon.
Wavemon detects an interface wlp8s0.

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.

Output of dmesg / messages is found in a previous email (buried in the
message thread)

https://lists.centos.org/pipermail/centos/2016-April/158703.html

Any advice?

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?

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).

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

[Philip V]

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.
