My current kernel was generated with genkernel from gentoo-sources-3.5.7 for my first Gentoo installation and works well up to now.
After emerging world i noticed that gentoo-sources-3.8.13 is available, and I've like to upgrade the kernel (for no particular reason but for have a newer and maybe "better" version).
This version is marked as stable, and my 3.5.7 is no more in http://packages.gentoo.org , why? Shall I upgrade the kernel?
A full manual configuration of the kernel is too difficult for me, so I thought genkernel could be helpful.

After the first compilation (--no-menuconfig) my wlan0 wasn't obviously in "ifconfig -a", and "modprobe ath9k" gave me an error.
I recompiled the kernel (--menuconfig) in this way:
Code:

networking support ->
        wireless ->
                <*>   cfg80211 - wireless configuration API
                [ ]     nl80211 testmode command
                [ ]     enable developer warnings

                [ ]     cfg80211 DebugFS entries
                [ ]     cfg80211 wireless extensions compatibility
                [ ]   lib80211 debugging messages
                <*>   Generic IEEE 802.11 Networking Stack (mac80211)
                Default rate control algorithm (Minstrel)  --->
                [ ]   Enable mac80211 mesh networking (pre-802.11s) support
                -*-   Enable LED triggers
                [ ]   Export mac80211 internals in DebugFS
                [ ]   Trace all mac80211 debug messages
                [ ]   Select mac80211 debugging features  --->

Code:

device drivers ->
        network device support ->
                wireless LAN ->
                        <*>   Atheros Wireless Cards  --->
                                [ ]   Atheros wireless debugging
                                < >   Atheros 5xxx wireless cards support

                                [*]   Atheros bluetooth coexistence support
                                <*>   Atheros 802.11n wireless cards support
                                [*]     Atheros ath9k PCI/PCIe bus support
                                [ ]     Atheros ath9k AHB bus support
                                [ ]     Atheros ath9k debugging
                                [*]   Atheros ath9k rate control
                                < >   Atheros HTC based wireless cards support
                                < >   Linux Community AR9170 802.11n USB support
                                < >   Atheros mobile chipsets support
                                < >   Atheros AR5523 wireless driver support
                                < >   Wilocity 60g WiFi card wil6210 support


Now the wlan0 is recognized, but if I try to connect to the LAN i get some errors...
This is the card (from lspci now that I write this post, while running the 3.5.7 kernel)

Code:

02:00.0 Network controller: Atheros Communications Inc. AR9485 Wireless Network Adapter (rev 01)
   Subsystem: Lite-On Communications Inc Device 6617
   Flags: bus master, fast devsel, latency 0, IRQ 17
   Memory at 54000000 (64-bit, non-prefetchable) [size=512K]
   Expansion ROM at 51000000 [disabled] [size=64K]
   Capabilities: [40] Power Management version 2
   Capabilities: [50] MSI: Enable- Count=1/4 Maskable+ 64bit+
   Capabilities: [70] Express Endpoint, MSI 00
   Capabilities: [100] Advanced Error Reporting
   Capabilities: [140] Virtual Channel
   Capabilities: [160] Device Serial Number 00-00-00-00-00-00-00-00
   Kernel driver in use: ath9k


and this is the error I get (3.8.13 kernel) if I try to connect

Code:

# ifconfig wlan0 down
# ifconfigl wlan0 up
# ifconfig wlan0 down
# ifconfigl wlan0 up                  // double down/up just as a test
# dhcpcd wlan0
......
......                                            // seems ok

Something is missing but I can't find out what.

¡Hi!

Read the output "dmesg" looking for errors about firmware.

Set this option in your kernel too:

This is a good idea (setting it, I mean -- so it shows [*] at the beginning rather than [ ]), as lots of tools still require wext (iwconfig, many wifi monitors, etc.).

If you just want to get a connection, you could also use wpa_supplicant with -Dnl80211 instead of -Dwext to make use of the newer config interface. (Or, perhaps better yet, you could do both of these to make use of the newer interface for wpa_supplicant, but still retain compatibility with older tools. The newer interface has some benefits, like more detailed error reporting to wpa_supplicant, for instance.)
