Ubuntu 15.10无线问题

Question

今天，我安装了Ubuntu15.10，我不能使用无线连接的互联网。在连接信息是写的，我是连接的，但我什么也做不了。当我与电缆连接时，一切都很好。我试着连接我的WiFi dongle，我在raspberry pi中使用它，一切都很正常。下面是我使用WiFi dongle的ifconfig：

Answer 1

您应该设置您的国家代码，脚本结果将显示您在波兰。

sudo iw reg set PL

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

文件的最后一行需要

REGDOMAIN=PL

保存文件并退出gedit。然后使用Network连接设置，并将IPv6设置为忽略连接，在IPv4设置中，添加8.8.8.8的DNS并保存。重新启动并查看是否有任何连接。
