any more details you can share? What kernel version, what specific 
device is wlp1s0, do you have any kernel logging.

When I wrote down the questions I was wondering how specifc I should be.

ok

Sure. I meant what brand and model.

Can you run following commands:
$ lspci
$ lsusb

> As for kernel logging, I simply don't know if I have it. Thanks

Ok. Can you run following command after aborting the hanging iw scan 
command:

$ dmesg

Gentoo does not seem to provide NetworkManager as a solution. I found 
this page [1]. Maybe it helps.

Well. iw is really for testing/debugging. Especially with WPA/RSN 
networks that do periodic rekeying you need wpa_supplicant. It will do 
the scanning on its own and establish connection and such.

You could also opt for using nmcli, but that might be what you tried 
already.

I am no gentoo expert, but let's try to get this working. I am following 
the wpa_supplicant section of the link I send earlier.

1. modify /etc/conf.d/net

Not sure if you only use wireless on the machine. Otherwise, you can 
copy the attach conf.net file:

$ sudo cp conf.net /etc/conf.d/net

2. install wpa_supplicant configuration

Edit attached wpa_supplicant.conf with your ssid and psk and copy it:

$ sudo cp wpa_supplicant.conf /etc/wpa_supplicant

3. restart networking

$ sudo /etc/init.d/net restart

Not sure if step 3. is entirely correct regarding the script name. I 
don't use Gentoo.

Arend,

Thanks for handling this problem for a user with Realtek equipment. Apparently, 
this user does not know about "Reply-All", thus I only saw their answers to your 
questions in the material you quoted.

Are you advising not to use iw and go the wireless-tools package?

Nope. Those are only useful for unprotected networks or WEP (which is 
almost same as unprotected). The two options are wireless-tools or 
wpa_supplicant. See below.

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

Ok. I will go with nmcli for now. I already configured it, so let it be. Here is good article about not-bloated wifi conf from command line:

Thank you for your time and have a good evening/day
