OL Intel Wireless 7260 not functional

User12625855-OracleSep 1 2014 — edited Sep 9 2014

Hi Folks,

I have OL (Oracle Linux Server release 6.5) running on my laptop (with a Wireless 7260 (rev 6b) Network Interface) and find the wifi (currently using a wpa_supplicant) seems to stop working after a few days .. this at kernel 2.6.32-431.23.3.el6.x86_64.

As I learned this wifi network interface is now natively functional, apparently from the 3.10 kernel onwards, I used yum update to install a later kernel from the Oracle Linux playground repo (now at kernel 3.15.10-3.15.y.20140819.ol6.x86_64) however found the wifi subsequently did not work .. at all.

After investigating further, I found I needed to place the appropriate iwlwifi-*.ucode to /lib/firmware (this rpm not in the ULN that I can see, btw) and rebooted only to find it still didn't work as expected.

I since discovered that the parameter CONFIG_IWLAGN was needed to be configured in the kernel .config file, which it was not for the yum updated 3.15 kernel I have installed.

# grep IWLAGN /usr/src/kernels/3.15.10-3.15.y.20140819.ol6.x86_64/.config
#

Can anyone suggest an appropriate way to get this working considering ..

The two options that occur to me are :

1. Request the playground folks set this .config parameter, generate another kernel instance and make it available (for a yum update).

2. Modify the .config myself and attempt to build a new kernel (I'm not sure I'd lose yum consistency .. log files, etc. nor have a built a kernel for a very long time).

Any help appreciated.

Rob
