Can not see all wireles networks linux 19 HP notebook

[nemjozsi]

Hi All,

I am new to linux, I have installed Linux Mint 19 Cinnamon, used the update manager and updated everything I could, but I still can not see all wireless networks, I can only see one network, but on my phone or under windows I can see also the other networks. The one I need is not on the list. I have opened the driver manager but it is empty and it says no proprietary drivers are in use. Can someone help me solve this problem?

Thank You!!!

It was working fine, but after I have made some Updates, now it again doesn't see the networks and I also can not connect if they sometimes appear any ideas?
