    Default Help required diagnosing random authentication failures.

    Recently acquired my first laptop and the world of wireless access is all rather foreign to me.

    I'm getting apparently quite random authentication failures when connecting to a wireless router, and am fumbling around in the dark somewhat as to the exact cause.

    (KDE, Network Manager, wpa_supplicant)

    The driver in use is rtl8821ce from forum user Sauerland's home repository.

    Looking at the log for wpa_supplicant on a successful authentication I see the following:

    Code:
    1565812781.727495: wlan1: Trying to associate with 4c:38:d8:03:c1:9f (SSID='ORION-a-5G' freq=5220 MHz)

    1565812781.815931: wlan1: CTRL-EVENT-CONNECTED - Connection to 4c:38:d8:03:c1:9f completed [id=0 id_str=]
    On a failed authentication:

    Code:
    1565813819.717660: wlan1: Trying to associate with 4c:38:d8:03:c1:9f (SSID='ORION-a-5G' freq=5220 MHz)

    1565813823.869159: wlan1: CTRL-EVENT-SSID-TEMP-DISABLED id=0 ssid="ORION-a-5G" auth_failures=1 duration=10 reason=WRONG_KEY
    I note (if I'm interpreting correctly) that immediately before the key negotiation there is:

    Code:
    wlan1: CTRL-EVENT-DISCONNECTED bssid=4c:38:d8:03:c1:9f reason=2
    I wonder what is "reason=2", as that may give a clue... "googling" this didn't turn up anything that seemed relevant.

    When working there is no problem with the connection itself, the following fragment from "iwconfig" shows (I believe) the actual wireless link to be OK, that's after some 60-70 minutes of use.

    Code:
    Link Quality=70/100  Signal level=31/100  Noise level=0/100
    Rx invalid nwid:0  Rx invalid crypt:0  Rx invalid frag:0
    Tx excessive retries:0  Invalid misc:0   Missed beacon:0
    I've discounted the signal level and quality by physically moving the laptop closer to the wireless access point, (quality and level then both approach 100/100), and I still see the random authentication failures.

    Hi
    Could also be interference from other wireless AP's in the same locale, on the AP, can it do a wireless scan, if so move your channel to a less congested one if you can as least two channels away from the most congested...

    When was the AP last rebooted, if it's been up awhile sometimes this helps...

    Default Re: Help required diagnosing random authentication failures.

    Interference would certainly account for the randomness with which this happens, but I'm seeing little to actually confirm that may be the cause.

    The AP I'm connecting to is an ISP supplied "UPC Connect Box", an all in one Cable Modem / Router / WiFi AP / VOIP gizmo...

    It has "Intelligent Wi-Fi", which (paraphrased to shorten) "regularly checks for best channel and channel width to minimize interference and congestion". I've read on my ISP's user forums that some people claim better performance by switching that feature off, and others by switching it on...

    Typically I see anything from 2-7 other "Available Connections" in Network Manager, however if I use "iwlist wlan1 scan" to see in detail, then only "Cell 08" is on 5GHz and on a different channel to myself. So I'm doubting if it's interference from other local APs.

    Referring back to the wpa_supplicant log, I've now found ( https://community.cisco.com/t5/wirel...s/ta-p/3113150 ) that "Reason=2" is "Previous authentication no longer valid", which so far is of little help.


    For the moment I'm "sort of" accepting it, are authentication failures such as this something that "just happen"...

    On a more positive note the 15.1 install on my newly acquired HP 255 G7 went quite well, I ran a live USB for a couple of days which didn't throw up any serious problems, so went ahead and did a network install.

    I've a few minor problems to fathom out, I'll post about those in a day or so if unable to resolve them myself.

    Hi
    I would set the channel and turn off any switching, can you run your setup as just 5GHz only, or it has to be both?

    I had already switched off 2.4GHz.

    With the "Intelligent Wi-Fi" and "Auto Channel Selection" also switched off I've not seen any change in behaviour, i.e. still random authentication failures.

    I don't think the problem is interference from another Wi-Fi nearby as I'm frequently the only person on 5GHz. I've taken to running "iwlist wlan1 scan" immediately after an authentication failure to see what other activity there is.

    I've also started to take note of the time at which it occurs, to see if it's more likely to happen at a particular time of day, but so far that seems quite random also, but I need to do that for a few more days before drawing any conclusions.

    Hi
    Can you post the output from;

    Code:
    systool -vm rtl8821ce
    This will see if there are any module options and if they can be tweaked.
