[SOLVED] Wifi-menu works weird

Hi everyone, Im a new arch-user.
My issue is somehow related to package "powertop"

One day I installed powertop, and did this

sudo powertop --auto-tune
sudo powertop --calibrate

After a while my screen backlight is so dark that I can barely see text, so I shutdown via power-button.
Then the network's somehow changed the way it works

I used to connect wifi like this:

sudo wifi-menu
(choose a wifi point scanned)
(enter password if there's no profile yet)
connected

Now what happened:

[curvas@localhost ~]$ sudo wifi-menu
Scanning for networks... Could not read interface p2p-dev-wlp3s0 flags: No such device
failed
No networks found

You may notice that p2p-dev-wlp3s0 issue above. Actually it showed before, too.
I didn't pay attention since wifi works well.

After

sudo ip link set wlp3s0 up

and wifi-menu scan the wifi successfully.
But if I choose one that I connected before, I got this:

Job for netctl@wlp3s0\x2d\x3b\x29\x205.service failed because the control process exited with error code.
See "systemctl status "netctl@wlp3s0\\x2d\\x3b\\x29\\x205.service"" and "journalctl -xe" for details.

Output of "journalctl -xe":

-- Unit netctl@wlp3s0\x2d\x3b\x29\x205.service has begun starting up.
Sep 21 20:54:03 localhost network[5065]: Starting network profile 'wlp3s0-;) 5'...

It said that wifi "wlp3s0-;) 5" had already been up

The systemctl status said the same:

[curvas@localhost ~]$ systemctl status "netctl@wlp3s0\\x2d\\x3b\\x29\\x205.service"

Sep 21 20:54:03 localhost systemd[1]: netctl@wlp3s0\x2d\x3b\x29\x205.service: Failed with result 'exit-code'.

There's one solution from https://wiki.archlinux.org/index.php/Netctl first one in Troubleshooting

sudo ip link set wlp3s0 down
sudo netctl start "wlp3s0-;) 5"

I can reach wifi right now, but still wanna figure out what happened
Hoping for your advice and feedback~
