![英特尔无线 N 7260 断开连接并要求输入密码](https://linux22.com/image/867668/%E8%8B%B1%E7%89%B9%E5%B0%94%E6%97%A0%E7%BA%BF%20N%207260%20%E6%96%AD%E5%BC%80%E8%BF%9E%E6%8E%A5%E5%B9%B6%E8%A6%81%E6%B1%82%E8%BE%93%E5%85%A5%E5%AF%86%E7%A0%81.png)
我使用的是 ubuntu 14.04 live usb,想在我的 Toshiba e45t 上与预装的 Windows 8.1(我知道如何操作)进行双启动。问题是每当我尝试连接到我的 WPA wifi(我所有的其他设备都可以连接到)时,每隔 2 秒它就会断开连接,并重新要求输入密码。这真的很烦人,你甚至无法使用该连接。奇怪的是,我的 wifi 在 Windows 8.1 和 Kali Linux 上都可以使用。这是我的输出dmesg

答案1
从您的帖子来看,问题在于您的 wifi 路由器/接入点使用的加密,iwlwifi 0000:03:00.0 wlan0: disabling HT/VHT due to WEP/TKIP use
因此您需要从 wifi 路由器的加密设置中消除 WEP/TKIP(如果可以)。您需要的是 WPA2-PSK 或 WPA2-AES,不要使用 WEP 或 TKIP,因为它们比较老旧,不太安全
