wlan0 wpa_supplicant and other

Question

can't establish connection wia WIFI. Can't understant what I'm doing wrong:

there is connection properties from my windows PC

this is my /etc/wpa_supplicant/wpa_supplicant.conf file

ctrl_interface=/var/run/wpa_supplicant GROUP=netdev
ap_scan=1
update_config=1
country=BY

network={
        proto=WPA2
        pairwise=CCMP
        priority=5
        ssid="TP-Link"
        psk="tzb2iXfU"
        scan_ssid=1
        key_mgmt=WPA-PSK
}

and this is output from

wpa_supplicant -i wlan0 -c /etc/wpa_supplicant/wpa_supplicant.conf

I already try to do it with:

raspi-config - same result
wext driver - not work, operation not permitted
with encrypted password - same result
without proto, pairwise, priority, scan_ssid, key_mgmt - same (or similar?) result

just a wild idea... The SSID "TP-Link" is rather generic. Could it be that there is another AP with that name around? If yes, please check the BSSID. — oh.dae.su, Feb 16 '19 at 18:40
The massive clue is ssid="TP-Link" auth_failures=3. Get rid of these lines proto=WPA2 pairwise=CCMP priority=5 and these lines scan_ssid=1 key_mgmt=WPA-PSK you don't need them and if they're wrong it will break the connection. If "TP-Link" is a hidden SSID then un-hide it. — Dougie, Feb 16 '19 at 19:10
temporarily remove security from the AP and try connecting again — jsotola, Feb 16 '19 at 19:52

Are you running Raspbian 2018-11-13 or some other OS version or distro? — Dougie, Feb 16 '19 at 21:42
I disable security, and after I run wpa_supplicant nothing happen - just Successfully initialized wpa_supplicant and no more messages. However, pi device did not receive ip address from router, and ping google.com did nothting. — degr, Feb 17 '19 at 08:45
Please follow this Check of WiFi connection until Checkpoint3 and tell us what Checkpoint failed for you. Please address me with @Ingo, otherwise I won't see your reply. — Ingo, Feb 17 '19 at 13:09
@Ingo, I can't understand what you want. Checkpoint 1 and Checkpoint 2 it is rpi image installation. Already did it yesterday. I have no /dev/sdb, I have /dev/mmcblk0, and output for sudo parted /dev/mmcblk0 print same as in example. I can't understand, what this guy do, when he put wpa_supplicant config into boot partition, because nothing in my system reference this config file. And yes, I can't pass checkpoint 3, because no changes — degr, Feb 17 '19 at 17:30

I guess you are using Raspbian and you wrote:

can't establish connection via WIFI. Can't understand what I'm doing wrong

so I assume your question is: How can I setup a WiFi connection with Raspbian?

In my comment I suggested to follow this Check of WiFi connection until Checkpoint3. Checkpoint1 and 2 are to ensure to have a defined starting point. For example I have seen users starting from a mixed up setup or asking for help saying: "I have done everything as described" but doesn't told they have the RasPi running in a virtual environment (docker, VM, sophisticated network environment etc.).

You started wpa_supplicant on the command line that isn't needed and may miss some dependencies. And as noted in your comments you doesn't know the default way to headless setup a WiFi connection by creating a wpa_supplicant.conf in the boot partition as documented at Setting up a Raspberry Pi headless. So it would be a good advise to follow the default setup until Checkpoint3.

As you wrote you can pass Checkpoint3. So you have a WiFi connection with internet access. This answers your question. Just use it.

If you are logging in to a school, university, or WPA-Enterprise wifi network try this (it has always worked for me):

network={
    ssid="wifi-network-trying-to-login"
    priority=1
    proto=RSN
    key_mgmt=WPA-EAP
    pairwise=CCMP
    auth_alg=OPEN
    eap=PEAP
    identity="your-user-name"
    password="your-password"
    phase1="peaplabel=0"
    phase2="auth=MSCHAPV2"
    }
