“通過本地選擇中止身份驗證（原因：3 = DEAUTH_LEAVING）”嘗試連接到wifi時
我在我的 PC 上安裝了 64 位的 Debian 9 stretch（GNOME 桌面）。安裝 atheros 韌體後自動檢測到我的 USB 無線適配器（TP-LINK TL-WN722N）：
apt-get install firmware-atheros但我無法連接到任何無線框架，無論它們是受密碼保護還是未受保護。
我插入了我的 USB。它被檢測到，發送身份驗證，獲得身份驗證，但立即中止身份驗證。禁用 IPV6 並沒有解決我的問題。這是我的

不知何故，我的韌體遇到了長介面名稱的問題。所以我執行了這個命令來防止它：
ln -s /dev/null /etc/systemd/network/99-default.link它奏效了。
正如其他人所說，問題是由設備獲得的非標準名稱（即不是 wlan*）引起的。連結 /dev/null 對我不起作用，所以我必須創建一個 udev 規則來重命名介面：
在
/etc/udev/rules.d/70-persistent-net.rules添加：
SUBSYSTEM=="net", ACTION=="add", DRIVERS=="?\*", ATTRS{product}=="802.11 n WLAN", ATTR{dev_id}=="0x0", ATTR{type}=="1", KERNEL=="wlan*", NAME="wlan1"調整
ATTRS{product}到您的特定設備。在這裡查看如何找到它
