Static ground noise when WiFi card is turned on

br flag

I have an annoying static noise problem when I turn on the Wifi. If I turn off the Wifi the noise disappears.

This problem is occurring in Ubuntu on a laptop on which I have installed both Ubuntu 20.04 and Windows, but on Windows the problem does not occur.

I have tried all the static noise solutions I have come across, but nothing has resolved it.

Hardware:

  • Acer Spin 5 laptot

  • -network
    description: Wireless interface product: QCA6174 802.11ac Wireless Network Adapter vendor: Qualcomm Atheros physical id: 0 bus info: pci@0000:01:00.0 logical name: wlp1s0 version: 32

     width: 64 bits
     clock: 33MHz

Think i tried:

  • all the links to ground noise and speaker noise i found on stack.

It may not have a solution. The reason is badly designed (i.e. made to a very cheap price point) hardware and on top some modified proprietary sound driver/software (Windows only) that masks the problem.

Hello and Welcome to Ask Ubuntu. I'm not an expert in this area of things; I just came across your question when reviewing posts in the "First Questions" queue. I made some slight edits, but overall the main suggestions I would have for you would be to (a) list the hardware involved, (b) list at least some of the links to things you have tried so that people don't waste time suggesting things you have already tried. I wonder if there might be a way to decrease the power to the WiFi card. Perhaps the Windows driver uses a different setting by default.

Most people don’t grasp that asking a lot of questions unlocks learning and improves interpersonal bonding. In Alison’s studies, for example, though people could accurately recall how many questions had been asked in their conversations, they didn’t intuit the link between questions and liking. Across four studies, in which participants were engaged in conversations themselves or read transcripts of others’ conversations, people tended not to realize that question asking would influence—or had influenced—the level of amity between the conversationalists.
