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)
I had similar problems installing 7.2 onto a couple of Dell E6xxx laptops with Intel Corporation Centrino Ultimate-N 5300/6300 cards. It lets me configure the network at install time but when I boot there is no wifi device.
Partial solution.
Laptop 1. ( install when 7.1 was latest release ) installed 7.1 no wifi installed 7.0 wifi works upgraded to 7.1 several months ago wifi works upgraded to 7.2 when it was released wifi works
Laptop 2 ( install when 7.2 was latest release ) installed 7.2 no wifi installed 7.0 wifi works upgraded to 7.2 ( last weekend ) no wifi
Any ideas.
