I'm using elementary OS 6. Currently my home WiFi router is not visible on WiFi networks so i have to connect my mobile to WiFi and make hotspot to access internet.

When scan WiFi all other networks are listed in list except my home router. I don't this this related to new OS but this is so annoying.

What could be the problem? any suggestions?

Update

I don't think the router is not compatible because sometimes suddenly it show up on WiFi list and can work normally but it disappears after a while. More impotently if i reset my WiFi router it shows up and works as normally. but after a day or two days this happens again.

Also it's not hidden because since sometimes i connects i have that WiFi saved in list so when i trying to connect it shows disconnected.

Router model is Huawei B312-926

    A little more information will be needed to offer an answer. Can you edit your question to include the brand and model of your computer, and perhaps the Terminal output of sudo lshw -c network, sudo lsusb, and sudo lspci? This will provide information about your hardware, making it possible to see if your machine is using the correct driver for the network card 👍🏻

  • I think your router is using 5Ghz band but your wifi adapter supports only 2.4Ghz. Confirm this, if I am correct. Btw on what device you are running elementary os on i.e. laptop or desktop? Sep 12 at 6:52

  • It's a laptop Dell xps 15, I have updated the question. Sep 13 at 10:00

    Hmm ... the QCA6174 has a history of being a little finicky on various Linux distributions with no clear solution that works for everybody. One additional question: do you have power-saving for the device turned off? This can sometimes ensure the network connection remains active (even when it's not idle)
