I have a atheros ar9285 wireless card. During minimal installation gentoo, I can not turn on my wireless card. So I can not continue installation.

Code:
#lspci
03:00.0 Network controller: Atheros Communications Inc. AR9285 Wireless Network Adapter (PCI-Express) (rev 01) 

Code:
#modprobe ath9k
#ifconfig wlan0 up
wlan0: ERROR while getting interface flags: No such device


How can I fix it?

After you you do modprobe, what does dmesg say?

EDIT:

Code:

dmesg | grep athk9k -a3

Hmm. Well, I saw this post (offsite, non-gentoo): http://www.backtrack-linux.org/forums/showthread.php?t=2603

I don't have any atheros nics so I can't try it for myself. Hope that helps.

Thank you. But in this solution, I need to download some files and reboot. So this will not fix my problem.

I just though I would throw this out:

If all else fails you can use other Linux distributions to install Gentoo. A good one is the System Rescue CD. It has excellent hardware support and it may bypass you current issue. Of course it kicks the can down the road. You will need to figure out what you need to do for your wireless card eventually.

I just thought I would add this.

OKAN,

The minimal install CDs support very little in the way of wireless.
Use System Rescue CD as your install CD. Its bigger then the minimal CD, allows you to follow the handbook with no extra steps and is based on Gentoo. It also has much better wireless support hen the liveCD.

The cover art also says "Don't Panic" in large friendy letters :)

I have installed gentoo using another live linux distro. I used genkernel for compile kernel. After installation, when I tried this command:
Code:
modprobe ath9k
FATAL: Module ath9k not found.

What can I do?

I take it that during installation the wireless was working fine, and it was upon rebooting into the Gentoo system that it no longer worked? I'm not too familiar with genkernel, but it sounds like you're going to have to check that the card's driver is being installed manually. Try to run genkernel with the parameter --menuconfig or --xconfig (if you have X installed and qt) and run a search to see if ath9k is built into the kernel, as a module, or just not at all. Also, you could try and do this:
Code:
grep ATH9K /usr/src/linux/.config
If it is configured in some way, this should tell you if it is built into the kernel or as a module, or not at all. If that command returns nothing, then the kernel configuration has the Atheros wireless cards setup turned off (and hidden) (I think).

Also, I'm assuming you set up your networking during the install. If you try to run '/etc/init.d/wlan0 restart', does it die (it should if the driver is not installed), or does it work? I remember I had some problems with my Dell laptop (*shudder*) a long time ago, when I first installed Gentoo on it, and it was just that I forgot to start the network interface.
