I have a few oqo2 units that I use for testing, normally using the
dongle for ethernet connection. Well supposedly they have atheros wifi. in dmseg I see:
OT: Looks like a pretty neat device.

Yes it is. I had 4, but one is misplaced. But I can't get the internal video working with any Linux I have tried, I have to use an external monitor or just run it as a headless server. It makes a great headless server for a portable LAN. Would love to get a GUI working on it though.
Oh... So it's no video and no Atheros wifi.

I press magic <fnc-?> per http://www.expansys.com/ft.**aspx?k=119902http://www.expansys.com/ft.aspx?k=119902but NetworkManager is not adding wifi as a networking device. There is no file under /etc/sysconfig/network-**scripts/ifc-* either. How can I get the wifi working?
Does the Atheros device show up in the output of ifconfig?
ifconfig -a
Only eth0 and lo
If it does, check the output of iwconfig. And of course nothing here.
If neither of those yield any success, dig into the output of lspci for
info on the Ath device. lspci -v lspci -v | grep -A10 -B2 thernet
with verbosity turne up another notch if you want more info lspci -vv | grep -A10 -B2 thernet
# lspci -vv | grep -A10 -B2 thernet

What version of CentOS? 6.4?
Still 6.3. I am going to rebuild on one of them tomorrow (or maybe tonight) to 6.4.
You might try an install of Fedora instead (as I suggest at the bottom
of this message) and try a newer kernel. Maybe you'll end up using the CentOS base and need to build a newer kernel yourself to have the proper driver for that Atheros chip. Since that unit will probably not be an Internet-facing host, you can run a custom kernel without any drawbacks.
Since CentOS 6.[34] is running a 2.6.32 kernel, I don't know that I place much belief in this information [0] (see post #4) helping. And this poster's Atheros is an AR5001.

By chance have you tried probing the driver by manually to test? modprobe ath5k lsmod | grep ath
ath5k 129334 0 ath 14106 1 ath5k mac80211 184028 1 ath5k cfg80211 157313 3 ath5k,ath,mac80211
ifconfig -a
And still only eth0 and lo listed.
I looked into messages and picked out the following:
Mar 11 01:37:17 oqo2 kernel: ath5k 0000:03:04.0: PCI INT A -> GSI 17 (level, low) -> IRQ 17 Mar 11 01:37:17 oqo2 kernel: ath5k 0000:03:04.0: registered as 'phy0' Mar 11 01:37:17 oqo2 kernel: ath5k phy0: Couldn't identify radio revision. Mar 11 01:37:17 oqo2 kernel: ath5k 0000:03:04.0: PCI INT A disabled
Perhaps this is my problem?
Yes.
I just boot F18 with LXDE, as the oqo will not boot of (at least my) DVD drive. Only CD. And it comes up with even the external video blank. But alt-ctl-F2 gets me a root login and in messages I see similar lines (can't upload them becase...)
I see the registered as 'phy0' and the next line says "unalbe to init EEPROM". The last that the probe failed with error -5
So this is rather bad. Time for a bug report?
Or at least find somebody who has Linux on an oqo2.
Use lspci to figure out what integrated graphics card it has and search for Linux support of that chipset.
On the topic of the wireless, search around your favorite search engine. You may have to contact the Madwifi project or whomever's driver you're using. http://www.redhat.com/archives/rhl-list/2008-October/msg02500.html
modinfo ath5k
You might also try the tips listed here: http://wiki.centos.org/HowTos/**Laptops/Wirelesshttp://wiki.centos.org/HowTos/Laptops/Wireless
Nothing helpful there. ath5k should just work.
Agreed.
You may end up checking change logs for kernel versions. :-/
F18 live CD iso.
Check modprobe's blacklist config for kicks.
Being an Atheros card I'd expect it to be rather well supported.

I checked in the bios that the card is enabled. The keyboard indicates that the function key function of the / key is to turn on the radio.
So the hardware switch has the radio turned on? Is there an indicator?
No indicator. That is part of the problem. All I can do is press the fun key (which is 'sticky' by default and has a little led to show it is activated), then press the ? (that has the radio icon in the place where the keys show what they do with the fun key), then the led goes off on the fun key. For other such combinations, you get what the key shows.
Have you tested the hardware with any other OS or distro so we know it's known good hardware?
No. I would have to dig out the base XP CD and install that.
You might also consider booting Fedora on it temporarily since you'll
have a much newer kernel.
Would my Centos kickstart work for Fedora? Or do I have to do a fedora install then copy the anaconda.cfg?
Never tried that myself. I'd expect some package names would differ slightly, but partitioning and what not would be compatible.
