嘿，我有一台新的华硕 Zenbook，配有英特尔 7265 无线网卡，几分钟内互联网连接就会变得非常慢/根本无法工作。我从英特尔网站 lwifi 下载了最新的驱动程序。有人知道哪里不对劲吗？这是来自 dmesg 的消息：

答案1
我拥有并成功使用了两台英特尔无线设备。几年来，我在数千篇论坛帖子中磨练了一些技巧。
首先，检查路由器中的设置。首选 WPA2-AES；而不是任何 WPA 和 WPA2 混合模式，当然也不是 TKIP。其次，如果您的路由器支持 N 速度，那么使用 2.4 GHz 频段的 20 MHz 信道宽度（而不是自动 20/40 MHz）可能会获得更好的连接性，尽管它可能会影响 N 速度。使用固定信道（1、6 或 11）比自动信道选择更能带来更好的连接效果。此外，请确保路由器未设置为仅使用 N 速度；首选自动 B、G 和 N。进行这些更改后，重新启动路由器。
接下来，我建议明确设置你的监管范围。检查你的：
sudo iw reg get
如果您选择 00，则这是一个通用的设置。请在此处查找您的设置：http://en.wikipedia.org/wiki/ISO_3166-1_alpha-2然后暂时设置一下：
sudo iw reg set IS
当然，如果不是冰岛，请替换您的国家代码。永久设置它：
gksudo gedit /etc/default/crda
如果您没有文本编辑器 gedit，请使用 nano 或 Kate 或 leafpad。
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，我在网络管理器中将 IPv6 设置为忽略：http://docs.fedoraproject.org/en-US/...pv6-ignore.png此示例适用于以太网，但您想要无线。
最后，建议大家更新固件。
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如何运行。
