AtomicPi - WLan Geschwindigkeit



  • Software

    Das System was ich hier teste ist ein Ubuntu mit LXDE Oberfläche.

    Welcome to Ubuntu 18.04.2 LTS (GNU/Linux 4.15.18-dli x86_64)
    Linux localhost 4.15.18-dli #1 SMP Fri Feb 22 15:10:35 UTC 2019 x86_64 x86_64 x86_64 GNU/Linux
    

    Test erfolgt ohne WLan-Antennen! Auf dem Board sind zwei Anschlüsse vorhanden!

    Fritzbox

  • Das Ganze jetzt mal vernünftig.

    Software

    Debian Buster LXDE auf dem neuesten Stand. Betriebssystem auf einer SSD an einem USB2.0 Hub (Nix anderes da, im Moment)

    Hardware

    • AtomicPi mit 5GHz WLan
    • Thinkpad mit 5GHz WLan

    Test

    AtomicPi war der Server, Thinkpad der Client und einmal -R

    Das ist schon mal deutlich schneller, als bei dem Test vorher.

    51b81139-1874-4cb5-8ff3-c2965bf3c11a-grafik.png

    Damit weiß ich jetzt, das WiFi klappt, aber der Networkmanager 😞 Ok, das bekomme ich auch noch irgendwie hin.



  • Ok, manche Dinge MUSS man einfach lösen 😂

    So, der Networkmanager kaspert immer rum und will die WiFi-Verbindung nicht starten.

    dmesg

    [ 3702.126994] wlx0007324c973d: aborting authentication with 44:4e:6d:a1:19:66 by local choice (Reason: 3=DEAUTH_LEAVING)
    

    Mal was suchen

    Lösung

    https://lists.debian.org/debian-user/2017/07/msg01453.html

    Umsetzung

    nano /etc/default/grub
    

    In die Zeile GRUB_CMDLINE_LINUX_DEFAULT folgendes ergänzen

    GRUB_CMDLINE_LINUX_DEFAULT="net.ifnames=0 console=ttyS0,115200n8"
    

    Das net.ifnames=0 verhindert das die Interfaces die neuen langen Bezeichnungen bekommen. Einige Treiber scheinen das nicht zu mögen, so auch der Treiber auf diesem AtomicPi Board.

    Danach noch kurz den Bootloader aktualisieren.

    sudo update-grub
    

    Neustarten. Problem gelöst!
