Ubuntu 20.04 LTS-英特尔无线/ WiFi接入和退出

问题总结:

Since upgrading from Ubuntu 19.04 to Ubuntu 20.04 LTS I notice in VOIP calls I was cutting in and out. I then noticed that this was happening regularly and the wifi was reauthenticating with the WAP.

详细信息和已进行的任何研究:

I ran the dmesg command to see if any diagnostic information was being logged for the problem and I could see the below:

$ dmesg -T | grep "wlp0s20f3\|iwlwifi"

我正在使用英特尔无线控制器。

$ lspci | grep Wireless
00:14.3 Network controller: Intel Corporation Cannon Point-LP CNVi [Wireless-AC] (rev 11)

我已经尝试过的:

我已经尝试了以下方法:

  1. 尝试使用专有驱动程序还是开源驱动程序(没有区别)。
  2. 强制无线网卡仅使用2.4频段。
  3. 调整了省电设置以禁用wifi卡。
[connection]
wifi.powersave = 2
  1. 全新安装Ubuntu 20.04,并安装了所有可用更新。

我已经看过现有的帖子,而且它们似乎并没有与我相同的问题,因此将不胜感激,我已尽力提供了尽可能多的信息,但是请告知我是否有什么都错过了。
