私は次のチュートリアルを読んだhttps://wiki.archlinux.org/index.php/Wireless_network_configuration#Get_the_name_of_the_interface
私が理解しているところによると、重要なステップはwpa_supplicant
以下を実行することです。dhclient
含まれる出力wpa_supplicant
:
...
wlp12s0: WPA: CTRL-EVENT-CONNECTED - Connection to ... completed ...
wlp12s0: WPA: Group rekeying completed with ... [GTK=TKIP]
...
その後、以下を実行しました。
$ sudo iw dev wlp12s0 link
Connected to ... (on wlp12s0)
SSID: ...

...
それから:
$ sudo dhclient -v wlp12s0

これは、IPが192.168.1.67
割り当てられているか割り当てられていないことを意味しますか?申し訳ありません。成功した結果がどのように出てくるのか分からない。とにかくそれ以降は、どのウェブサイトにもpingを送信できませんでした。ただし、自宅の他のコンピュータからpingを送信することはできます。
