Hi, I installed gentoo base system yesterday with this guide. Then, I' m having trouble with WPA2 wireless setup. To see if ath9k module were installed, used this code:
Code:
 find /lib/modules/ -name '*.ko'

But the output was just:
Code:
/lib/modules/3.6.11-gentoo/kernel/net/netfilter/xt_LOG.ko
/lib/modules/3.6.11-gentoo/kernel/net/netfilter/xt_mark.ko
/lib/modules/3.6.11-gentoo/kernel/fs/ntfs/ntfs.ko
/lib/modules/3.6.11-gentoo/kernel/arch/x86/ia32/ia32_aout.ko
/lib/modules/3.6.11-gentoo/kernel/arch/x86/kernel/test_nx.ko
/lib/modules/3.6.11-gentoo/kernel/drivers/gpu/drm/mga/mga.ko
/lib/modules/3.6.11-gentoo/kernel/drivers/char/kcopy/kcopy.ko
/lib/modules/3.6.11-gentoo/kernel/drivers/media/video/v4l2-common.ko
/lib/modules/3.6.11-gentoo/kernel/drivers/media/video/v4l2-int-device.ko
/lib/modules/3.6.11-gentoo/kernel/drivers/media/video/gspca/gspca_main.ko
/lib/modules/3.6.11-gentoo/kernel/drivers/media/video/videodev.ko
/lib/modules/3.6.11-gentoo/kernel/drivers/hid/hid-logitech-dj.ko
/lib/modules/3.6.11-gentoo/kernel/drivers/hid/hid-sony.ko


It's the first time I've configured and compiled a kernel, and even first time with gentoo. But is strange that there are too few modules... right? :roll:

rudregues,

Welcome to gentoo :D

The answer to your question is no. Every conceivable driver for every conceivable hardware device is not enabled.

It's up to the installer (in this case you) to enable the drivers for your specific devices :wink:

Thanks BillWho, gentoo is really great. I hope someday use gentoo in my desktop too. 8)

I don't know if I get what you say... but are you telling me I must recompile the kernel and select modules I didn't at first attempt? Or I must someway load the modules with modprobe or similar?

Well, you can't load non-existent modules so what needs to be done is make menuconfig . Then navigate to
│ -> Device Drivers │
│ -> Network device support (NETDEVICES [=y]) │
│ -> Wireless LAN (WLAN [=y]) │
│ -> Atheros Wireless Cards (ATH_COMMON [=n]) │

You'll also have to enable other drivers that that driver depends on e.g cfg80211 and mac80211:
Code:
laptop ~ # lsmod|grep ath9k
ath9k                  95355  0
ath9k_common            1881  1 ath9k
ath9k_hw              331655  2 ath9k_common,ath9k
ath                    14954  3 ath9k_common,ath9k,ath9k_hw
mac80211              366097  1 ath9k
cfg80211              168255  3 ath,ath9k,mac80211


When you're done enabling your pertinent hardware drivers then you have to compile the kernel.

It's that simple :D

Bill, your answer is very clarifying. Now it's time to do some reverse engineering with lsmod in Sabayon and turn easier to discover the drivers I need. :wink:

Thank you very much.
