Meine WWAN-Verbindung (LTE, derzeit Roaming) bricht 1-2× am Tag ab. Es handelt sich um eine Sierra Wireless MC7710 Mini-PCIe-Karte in einem Lenovo Thinkpad X220, OS ist Linux Mint Cinnamon 20.1 mit Kernel 5.4.0-135-generic. Ich habe in den Logs lediglich IPs, Serials usw. ein bisschen unkenntlich gemacht, vielleicht war ich dabei über-paranoid. ;)
In /var/log/syslog steht, wenn die Verbindung abbricht:

Mit der "CONNECTED_GLOBAL"-Nachricht läuft dann die Internetverbindung offensichtlich wieder. Das initiale
usb 2-1.4: USB disconnect, device number 7
deutet für mich aber klar darauf hin, dass tatsächlich auf meiner Seite die Verbindung abbricht (weil die LTE-Karte "disconnected" wird?).
Die Frage also: warum ist das so bzw. was kann ich dagegen tun?
Anscheinend ist die Karte intern irgendwie per USB angebunden? Verbindung zu diesem ähnlichen Thema hinsichtlich Bluetooth (https://www.forum-3dcenter.org/vbulletin/showthread.php?t=613537) möglich? :uponder:
In /var/log/syslog steht, wenn die Verbindung abbricht:

Mit der "CONNECTED_GLOBAL"-Nachricht läuft dann die Internetverbindung offensichtlich wieder. Das initiale
usb 2-1.4: USB disconnect, device number 7
deutet für mich aber klar darauf hin, dass tatsächlich auf meiner Seite die Verbindung abbricht (weil die LTE-Karte "disconnected" wird?).
Die Frage also: warum ist das so bzw. was kann ich dagegen tun?
Anscheinend ist die Karte intern irgendwie per USB angebunden? Verbindung zu diesem ähnlichen Thema hinsichtlich Bluetooth (https://www.forum-3dcenter.org/vbulletin/showthread.php?t=613537) möglich? :uponder:
