Wpa-Supplicant
使用 wpa_supplicant 設置 WPA2 個人的問題
系統：archlinux（最後更新）
我插入了一個 USB 無線加密狗，基本的東西似乎開箱即用，但是我似乎無法正確配置 wpa_supplicant 以獲得連接。它總是告訴我我可能有一個錯誤的密鑰 - 我知道我沒有，因為這是我在其他系統中使用的，所以我肯定缺少一些東西。
我使用 MAC 過濾，但設置正確。
我可以檢查我的界面
> iw dev phy#0 Interface wlp0s29f0u1 ifindex 3 wdev 0x1 addr <<mywirelessmac>> type managed我可以掃描可用的網路
> iw dev wlp0s29f0u1 scan該命令提供了許多與我的其他系統相匹配的結果和資訊。包括我的 ssid：

> cat /etc/wpa_supplicant/wpa.conf ctrl_interface=/var/run/wpa_supplicant update_config=1 network={ ssid="<<ssid>>" psk=<<either "mypassphrase" or [the result of wpa_passphrase ssid passphrase] neither works>> key_mgmt=WPA-PSK # I tried without, same result ieee80211w=1 # I tried without (both), same result }我嘗試了兩種方法來啟動 wpa_supplicant，結果完全相同：
> wpa_supplicant -B -Dnl80211 -iwlp0s29f0u1 -c /etc/wpa_supplicant/wpa.conf Successfully initialized wpa_supplicant（殺死 -9 並重新啟動）
> wpa_supplicant -B -Dnl80211,wext -iwlp0s29f0u1 -c /etc/wpa_supplicant/wpa.conf Successfully initialized wpa_supplicant現在來看看這兩種情況會發生什麼：

所以我真正的問題是理解我的設置有什麼問題，它會生成第一條錯誤消息。這就是我希望得到一點幫助的地方。
謝謝。
糟糕，似乎重新啟動我的系統可以解決問題。
感謝一路上的幫助。
