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

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)
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.

Output of rfkill list?

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.

(yes, I toggled the hardware switch, which seemed to only affect the Bluetooth again.) ifconfig does not report any wireless adapter.

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

Do you have iwl2030-firmware.noarch installed?
