WLAN Verbindung sporadisch nicht möglich

[Mrte]

Hallo zusammen,

aktuell habe ich folgendes Problem: Mein Laptop lässt sich nur noch sporadisch mit dem WLAN verbinden. D.h. wenn ich auf "Verbinden" klicke, klappt es manchmal, und manchmal nicht. Per LAN Kabel lässt sich der Laptop verbinden. Alle andere Geräte im WLAN haben keine Probleme mit der Verbindung. Also habe ich meinen Laptop letztendlich formatiert, was aber ebenfalls keine Verbesserung gebracht hat. Selbst wenn kein anderes Gerät im WLAN ist, tritt der Fehler auf.

Folgende Daten:
Router: Vodafone Station
Firmware: AR01.02.068.10_082720_711.SIP.10
Tarif: 2play Vorteilstarif 150
Einzugsgebiet: BW
Netzwerkadapter Laptop: Intel Centrino Wireless N-100

Seit wann tritt das Problem auf? ca. August 2020, davor war Verbindung via WLAN ohne Probleme möglich
Signalempfang? Meiner Meinung nach ausreichend, ich kann hier aber gerne bei Bedarf die Signalstärke teilen

Was bisher geschah und keine Verbesserungen gebracht hat:
- Router geresettet
- Router und Laptop nebeneinander gestellt
- Einstellungen im Router variiert:
- Kanaele angepasst
- Bandbreite angepasst
- 2.4 Ghz und 5 Ghz Netz getrennt/zusammengeführt
- WLAN Name geändert
- WLAN PW geändert
- Band Steering aktiviert/deaktiviert
- Laptop Netzwerkadapter Einstellungen variiert.

Alles ohne Erfolg. Nun die Logfiles des Routers analysiert: Es scheint, als schickt mir der Router manchmal DEAUTH Anfragen mit "unspecified; Code=1" sendet (leider nicht in diesem Logfile zu sehen) und manchmal REASON-CODE-DESCR=PREV_AUTH_NOT_VALID.

Die MAC adressen im logfile wurden mit mcadress1-4 ersetzt.
Während der Aufzeichnung des Logfiles war ich mit dem Laptop via LAN verbunden.

Hallo Mrte,

bitte schick mir dazu einmal eine PN mit Angaben zum Vertragsinhaber, Geburtsdatum und vollständiger Adresse + Kundennummer (wenn Du diese zur Hand hast). Ich schaue mir das dann mal genauer an.

Viele Grüße,

Maria
