Why can't xubuntu see wifi?

Question

linux

Hello everyone, I installed xubuntu on a laptop, but it does not see the wi-fi network, although it reacts to the on / off button of the wi-fi module. I checked for the presence of drivers, they are standing and active, but the network does not see, only the wired one works. Also, sometimes the bluetooth module stops working (I connected a mouse, and after a while it stops working, plus Linux stops finding other bluetooth)
