This did the trick. I can now scan networks and I found mine. But how I actually connect to my network?

It pulled a bunch of dependencies, though I used -X flag in USE variable not to use X server. the compile took about an hour and after all this, my system became unstable. It doesn't at all feels right, it is clunky. For now I am building gentoo laptop in pure console mode, so from all my research, iw is the only CLI tool for wireless and I like the fact it doesn't need bunch of dependences. I already installed it and I like it, so would you be so kind to get me through a set up? Documentation seems confusing. Thanks > > Well. iw is really for testing/debugging.
