Ubuntu 15.10无线问题

今天，我已经安装了Ubuntu 15.10，但无法使用具有无线连接的互联网。在连接中，写有我已连接的信息，但我无能为力。当我用电缆连接时，一切都很好。我试图连接我在树莓派中使用的WiFi加密狗，并且一切正常。这是我的带无线加密狗的ifconfig：

您应该设置国家代码，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

文件的最后一行需要是

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8.8.8.8的DNS并保存。重新启动，看看是否可以连接
