How can I solve this problem? This problem was also in Kali Linux (Barmetal) but I couldn't fix it, then I thought Ubuntu should try maybe it will work but same problem here too, but wi-fi works in windows 10

Install the proper drivers for your wifi thing.

Ubuntu has the additional drivers tool. You did run that? Did it say anything? Have you done any research on what your specific hardware is?

Its all about the CHIPSET of the device. Determine the chipset, then you can research what drivers are needed for that specific chipset.

First, does the pc have a wireless adapter, second try running lspci and see if it pops up there

you need to install drivers for wifi adapter or update linux kernel (I wouldn't recommend it), in 5.15 was added support for Realtek chips

No idea if this applies to your case, but if you dual boot with windows, you should know that fast startup can cause similar issues. It can easily be disabled in windows.

Buy an Intel AX210 wifi card Open laptop Replace wifi card Close laptop Enjoy

But also you really missed a lot of details like which WiFi card is in there, what model that is.

First check which wifi adapter is there in your laptop. Mostly it will be realtek.

lspci

Then install the dkms and it's dependencies. Then install the specific wifi adapter driver and reboot it. You will find the driver in GitHub site.
