Problem with setting up WPA2 personal with wpa_supplicant [closed]

Question

System: archlinux (last updates)

I plugged in a USB wireless dongle and basic things seem to work out of the box, however I can't seem to be able to configure wpa_supplicant properly to get a connection. It always tells me I likely have a wrong key - which I know I don't as this is what I use with my other systems, so there is most certainly something I am missing.

I use MAC filtering but this is set-up correctly.

I can check my interface

> iw dev
phy#0
    Interface wlp0s29f0u1
        ifindex 3
        wdev 0x1
        addr <<mywirelessmac>>
        type managed

I can scan the available networks

> iw dev wlp0s29f0u1 scan

This command gives lots of results and information that matches my other systems. Including my ssid:

I have a basic profile:

> cat /etc/wpa_supplicant/wpa.conf
ctrl_interface=/var/run/wpa_supplicant
update_config=1

network={
    ssid="<<ssid>>"
    psk=<<either "mypassphrase" or [the result of wpa_passphrase ssid passphrase] neither works>>
    key_mgmt=WPA-PSK # I tried without, same result
    ieee80211w=1 # I tried without (both), same result
}

I tried two ways to start wpa_supplicant with exactly the same results:

> wpa_supplicant -B -Dnl80211 -iwlp0s29f0u1 -c /etc/wpa_supplicant/wpa.conf
Successfully initialized wpa_supplicant

(kill -9 and restart)

> wpa_supplicant -B -Dnl80211,wext -iwlp0s29f0u1 -c /etc/wpa_supplicant/wpa.conf
Successfully initialized wpa_supplicant

Now on to what happens in both cases:

> wpa_cli
> scan
> scan_results
<<mac>> 2412    -65 [WPA2-PSK-CCMP][ESS]    <<ssid>>
<3>CTRL-EVENT-SCAN-STARTED 
<3>CTRL-EVENT-SCAN-RESULTS 
<3>WPS-AP-AVAILABLE 
<3>CTRL-EVENT-SSID-REENABLED id=0 ssid="<<ssid>>"
<3>SME: Trying to authenticate with <<mac>> (SSID='<<ssid>>' freq=2412 MHz)
<3>Trying to associate with <<mac>> (SSID='<<ssid>>' freq=2412 MHz)
<3>Associated with <<mac>>
<4>WPA: Failed to set PTK to the driver (alg=3 keylen=16 bssid=<<mac>>)
<3>CTRL-EVENT-DISCONNECTED bssid=<<mac>> reason=1 locally_generated=1
<3>WPA: 4-Way Handshake failed - pre-shared key may be incorrect
<3>CTRL-EVENT-SSID-TEMP-DISABLED id=0 ssid="<<ssid>>" auth_failures=<x> duration=<xx> reason=WRONG_KEY
<3>CTRL-EVENT-SCAN-STARTED 
<3>CTRL-EVENT-SCAN-RESULTS 
<3>WPS-AP-AVAILABLE 

There are two things that jump out:

<4>WPA: Failed to set PTK to the driver (alg=3 keylen=16 bssid=<<mac>>)
<3>CTRL-EVENT-SSID-TEMP-DISABLED id=0 ssid="<<ssid>>" auth_failures=<x> duration=<xx> reason=WRONG_KEY

I believe the second is a symptom of the first.

So my real problem is understanding what is wrong with my set-up that it generates the first error message. That's where I am hoping for a bit of help.

Thanks.

Answer 1

Oops, seems like rebooting my system cleared the problem.

Thanks for the help along the way.
