network – Ubuntu detects only a few Wi-Fi networks

I've recently installed Ubuntu in dual-boot with Windows 10 on my HP. The problem is, I only detect with Ubuntu a small part (and with very low performance) windows that the network detects perfectly; in particular, it does not detect my college network …

I imagine it's a driver problem, but I can not find any recent information online, so I'm a little scared of doing something wrong with my case, and that could be end up in a worse situation.

Here is what i get from iwconfig:

enp2s0 no wireless extensions.

lo no wireless extensions.

This from the lshw -C network
