Qualité / force du signal du modem non disponible de ModemManager 16.04 LTS

1

J'utilise un modem MC7403 en 16.04 LTS. La qualité du signal renvoyée par le gestionnaire de modem "mmcli -m 0" renvoie 0. Le gestionnaire de réseau le fait-il, comment puis-je obtenir une mise à jour correcte de la puissance du signal?

Après la connexion initiale, il est correct, mais après 30 secondes, il renvoie 0. La connexion au fournisseur de services Internet et à Internet fonctionne toujours, mais je ne peux plus contrôler la force du signal.
Il semble que modemmanger commence à regarder / dev / ttyUSB0 au lieu de / dev / ttyUSB2. À 30 secondes, il y a aussi cette erreur dans le journal du gestionnaire de réseau.

IPV6CP: expiration du délai d'envoi de la demande de configuration

Le journal montre cette erreur.

La réponse courte est 16.04.1 Le noyau LTS 4.4. * N'est pas assez récent et ne supporte pas correctement les interfaces qmi. Vous devez mettre à jour le noyau ou utiliser Ubuntu 16.10 ou plus récent. De plus, le modem-modem doit probablement être mis à niveau. J'ai utilisé les AAE fournis par Aleksander pour le faire fonctionner en 16.04 LTS à court terme.

Réponse longue J'ai été en mesure de collecter les journaux ci-dessus à l'aide de cette méthode de débogage .

J'ai collecté de nouveaux journaux à la demande de l'un des développeurs de libmbim. À partir de là, il pouvait voir, comme on peut le voir plus haut, qu’il utilisait AT + PPP. Aleksander a suggéré que j'ai besoin d'un nouveau noyau et d'un gestionnaire de modem pour que cela fonctionne.

Quelques notes sur le modem. Utiliser AT! USBCOMP? J'ai pu voir que ces modems n'étaient pas configurés pour mbim uniquement qmi. J'ai essayé mbim dans 16.04 LTS mais cela ne fonctionnait toujours pas et nécessitait un gestionnaire de noyau et de modem plus récent.

Signaler la force du signal ne vous inquiète peut-être pas, mais le fait d’utiliser des interfaces inadéquates limitera également votre vitesse, du moins dans mon cas.

Lorsque je travaillais avec AT + PPP, je passais à 35 Mbps et à 18 Mbps. En utilisant les interfaces LTE, je suis en train de passer de 35 à 45 Mps et de 23 à 29 Mbps
