直到我升级到纤维,我才注意到它。我的手机高达400 max,但我的ubuntu是最大150 max。我读了很多方法和问题,它们把我的速度从50 MBPS提高到了现在。
起初,wifi的连接速度是50 MBPS最大,但是一旦我删除了省电器并修复了avahi中的一个bug,连接速度就达到了477 MBPS,但是互联网速度(speedtest.net)不如我的手机快。
以太网电缆的速度和我的android一样快,问题完全是wifi。以下是我发现的一些问题:

我有同样的英特尔Wi模块,这解决了问题。
编辑/etc/modprobe.d/iwlwifi.conf并在文件options iwlwifi bt_coex_active=0的末尾添加以下内容
然后执行sudo modprobe -r iwlwifi和sudo modprobe iwlwifi,或者重新启动。
