Thank you for taking the time to read my post. smile.gif

I have a HP Pavilion Entertainment PC with a Atheros AR9285 Wireless Network Adapter that I can't figure out how to enable. "Enable Wireless" is greyed out under NetworkManager and I can't find a set of Fn keys or other switch to enable the wireless card.

Any Ideas on how to enable this wireless card?

According to the vendor:device ID pairing 168c:002b of your wireless device, it is supported by the ath9k driver. An attempt to build kmod-ath9k by ELRepo did not go well [1]. However, this device seems to be supported by compat-wireless [2,3]. So, you may want to give it a try.

Thank you for the response Toracat.

I gave the kmod-compat-wireless a try but after installing kmod-compat-wireless the kernel module for encryption would no longer load, keeping this laptop from booting since it has encrypted partitions. sad.gif

I also tried to use a usb dongle type wifi to no avail. I am also unable to enable the usb dongle.
I have also booted a few different flavors of live CDs to no avail. Mint shows that the wifi card is in airplane mode but turning airplane mode off has no effect.

Still looking for a solution.

smile.gif I was able to unlock the wireless hardware lock! smile.gif

This one was weird,
I was not able to get the wireless hardware lock to unlock from linux. I was however able to get the hardware lock to unlock from windows but, after a clean windows shutdown, and then booting linux the hardware lock was on again. The answer for me (and this HP dv6 win7) was to boot windows and make sure wireless was working. I then held down the power button until the laptop powered off. I then booted SL and the hardware lock was off and wireless was working. smile.gif

Thanks to everyone who helped

I always tend to blame these things on NetworkManager. It would be interesting, if you had inclination, to do a minimal install, remove NetworkMangler, and see if you had the same problem. Did you try unlocking with rfkill?

Hello Scottro,

I did try to unlock with rfkill. Rfkill had no effect. I was leaning in the same direction as you, blaming NM. I had tried a few different flavors of livecds. I even tried one I had made without NM to no avail.

I am pretty sure ether windows or hp's wireless blob was locking the hardware lock on a clean shutdown of windows. After forcing a shutdown from windows by holding down the power button the lock was off on reboot.

The laptop in question is a family members laptop. That family member was tired of messing with windows and wanted to try scientific linux. I tried to get wireless going on that laptop in my spare time for a few weeks. Now I have less hair and the thing is working I just want to give it back. If it was mine I would be up for some detective work in order to figure out what was causing the issue, but since it is not mine I just want to give it back to its owner with the hope I never see the dam thing again. wink.gif

I admit I laughed when I read your post, but it was a sympathetic laugh.

Makes perfect sense to me. Get it back to them and be done with it.

I have a sneeking suspicion that was a empathetic laugh. wink.gif biggrin.gif tongue.gif
