WiFi AR9462コントローラを搭載したLinuxMintシステムでWake on Wireless LAN（WOW、WoWLAN）を有効にしようとしています。いくつかのカーネルバージョン（例：3.19、...）を試してみました。現在私はUbuntuバージョン4.4.0-47を実行しています。
$ uname -a
Linux xxx 4.4.0-47-generic #68~14.04.1-Ubuntu SMP
ネットワークドライバath9kはWOW、特にAR9462をサポートしていると言われています。
$ lshw -C network

私はUbuntuプリコンパイルされたカーネルを使います。したがって、ドライバ/boot/config-4.4.0-47-genericでWOWサポートを有効にする必要があります。ath9k
$ cat config-4.4.0-47-generic | grep WOW
CONFIG_ATH9K_WOW=y
iwただし、コマンドを使用してWOWを有効にしたい場合は、次の出力が表示されます。
$ sudo iw phy phy0 wowlan show
command failed: Operation not supported (-95)
$ sudo iw phy phy0 wowlan enable magic-packet
command failed: Operation not supported (-95)
残念ながら、iw phy0 infoWOWのサポートは表示されません。
$ iw phy0 info

私のWiFiカードでWake on Wireless LANを有効にするためにシステムをどのように説得しますか？
