Ubuntu 15.10 无线问题

今天我安装了 Ubuntu 15.10，但无法使用无线连接上网。连接信息显示我已连接，但我什么也做不了。当我用有线连接时，一切正常。我尝试连接我在 raspberry pi 中使用的 WiFi 加密狗，一切正常。这是我使用 WiFi 加密狗的 ifconfig：

您应该设置您的国家代码，脚本结果将表明您在波兰

sudo iw reg set PL

然后我们将更改 crda 文件 gksudo gedit /etc/default/crda

该文件的最后一行需要

REGDOMAIN=PL

保存文件并退出 gedit。然后使用网络管理器连接设置并将 IPv6 设置为忽略您的连接，并在 IPv4 设置中添加 DNS 8.8.8.8 并保存。重新启动并查看您是否可以建立任何连接
