Hi, comunity!
Installing Qualcomm Atheros AR9227 Wireless Network PCI Adapter...
I tried WEXT + ath9k + wpa_supplicant + dhcpcd configuration

So my kernel is:
Code:
den ~ # cat /usr/src/linux/.config | grep WEXT
CONFIG_WEXT_CORE=y
CONFIG_WEXT_PROC=y
CONFIG_CFG80211_WEXT=y

Code:
den ~ # cat /usr/src/linux/.config | grep ATH9K
CONFIG_ATH9K_HW=y
CONFIG_ATH9K_COMMON=y
CONFIG_ATH9K_BTCOEX_SUPPORT=y
CONFIG_ATH9K=y
CONFIG_ATH9K_PCI=y
# CONFIG_ATH9K_AHB is not set
# CONFIG_ATH9K_DEBUGFS is not set
# CONFIG_ATH9K_WOW is not set
CONFIG_ATH9K_LEGACY_RATE_CONTROL=y
CONFIG_ATH9K_RFKILL=y
# CONFIG_ATH9K_HTC is not set


Network and wpa_supplicant configuration be like:
Code:
den ~ # cat /etc/conf.d/net
modules_wlp5s0="wpa_supplicant"
wpa_supplicant_wlp5s0="-Dwext"
config_wlp5s0="dhcp"

Code:
den ~ # cat /etc/wpa_supplicant/wpa_supplicant.conf
ctrl_interface=DIR=/var/run/wpa_supplicant GROUP=wheel
update_config=1
ap_scan=1


Code:
den ~ # ls -l /etc/init.d/net.wlp5s0
lrwxrwxrwx 1 root root 6 Oct 23 15:13 /etc/init.d/net.wlp5s0 -> net.lo
den ~ # rc-service net.wlp5s0 start
 * Bringing up interface wlp5s0
 *   Starting wpa_supplicant on wlp5s0 ...
Successfully initialized wpa_supplicant                                                                                                                                                     [ ok ]
 *   Starting wpa_cli on wlp5s0 ...                                                                                                                                                         [ ok ]
 *   Backgrounding ... ...
 * WARNING: net.wlp5s0 has started, but is inactive


Finally scanning for networks by wpa_cli.... And no my ssid here:
Code:
den ~ # wpa_cli -i wlp5s0
wpa_cli v2.2

Try adding your wifi information into /etc/wpa_supplicant/wpa_supplicant.conf
Code:
ctrl_interface=DIR=/run/wpa_supplicant GROUP=wheel
ap_scan=1
network={
Ssid="Wifi_ssid"
proto=WPA2
psk="wifi_password"
priority=2
}

Restart the service and see if it works

Already done but no result.
There is one more gentoo machine with wireless adapter. It works.
Here is a part from another wpa_supplicant.conf.
Code:
network={
   ssid="SSID"
   scan_ssid=1
   psk="PASSWORD"
   proto=RSN
   priority=1
}

Connection is the next problem. We need to see the access point at first!)

:/
I had a friend who I helped set up his Qualcomm Atheros (I can't remember what model).
But I can't remember the configuration.
I will post it once I get my hands on it.

One more strange thing.
Interface's service is down but it has an ip address. How?
Code:
den ~ # rc-service net.wlp5s0 status
 * status: stopped

Code:
den ~ # ifconfig
enp3s0: flags=4163<UP,BROADCAST,RUNNING,MULTICAST>  mtu 1500

Terribly sorry. But my friend is being un-cooperative and I can't get his config file.
But it is weird that you have an ip address but no internet connection.
Maybe ur network isnt connected to internet?>
Try connecting to a different network. e.g. your friend's house :\

I find out the problem.
I applied WEXT driver. It is old one and it has problems with 802.11n standart.
The solution is to use its lerasy - nl80211 driver.
It is nessesery to enable it in kernel and give a command to wpa_suuplicant to apply it.
Code:
den ~ # cat /etc/conf.d/net
...
### Wireless client network ###
modules_wlp5s0="wpa_supplicant"
# wpa_supplicant_wlp5s0="-Dwext"
wpa_supplicant_wlp5s0="-Dnl80211"
config_wlp5s0="dhcp"
...

Now it works. Thx for help!)

According to loc cit 5 https://wiki.gentoo.org/wiki/Wpa_supplicant#cite_note-5 and to my own experience that line in /etc/conf.d/net should no longer be needed.
