Ubuntu 16.04 wifi Intel 7265慢速/断开连接

Question

嘿，我有一个新的华硕Zenbook与英特尔7265无线网卡，并不断在几分钟内，互联网连接变得非常缓慢/根本不工作。我有最新的英特尔网站伊威菲的司机。有人知道什么是不对的吗？下面是来自dmesg的消息：

Answer 1

我拥有并成功使用了两台英特尔无线设备。我已经磨练了一些技巧在几年和数以千计的论坛帖子。

首先，检查路由器中的设置。优先考虑WPA2-AES；没有任何WPA和WPA2混合模式，当然也不是TKIP.第二，如果您的路由器能够达到N个速度，那么在2.4个GHz频段内，信道宽度为20 GHz，而不是自动的20/40 MHz，可能会更好地连接起来，尽管这可能会影响N个速度。我也有更好的运气一个固定的频道，要么1，6或11，而不是自动频道选择。另外，要确保路由器不被设置为只使用N个速度；自动B、G和N是首选。在进行这些更改后，重新启动路由器。

接下来，我建议显式地设置您的管理域。检查你的：

sudo iw reg get

如果你得到00，那是一个单一大小-也许-适合-所有的设置。在这里找到您的：http://en.wikipedia.org/wiki/ISO_3166-1_阿尔法-2然后临时设置它：

sudo iw reg set IS

当然，如果不是冰岛，就用你的国家代码来代替吧。永久设置：

gksudo gedit /etc/default/crda

如果您没有文本编辑器gedit，请使用nano或kate或传单垫。

将最后一行改为：

REGDOMAIN=IS

仔细校对，保存并关闭文本编辑器。

接下来，我将IPv6设置为在Network中忽略：http://docs.fedoraproject.org/en-US/...pv6-ignore.png --这个示例用于以太网，但您需要无线。

最后，我建议您更新固件。

cd /lib/firmware
sudo wget https://github.com/OpenELEC/iwlwifi-firmware/raw/master/firmware/iwlwifi-7265D-21.ucode

重新启动并告诉我们它是如何工作的。
