Impossible de se connecter à Internet sur un ordinateur portable Ubuntu 14.0.4 avec un modem USB AC2739 zte (reliance cdma)
Beaucoup d'utilisateurs de Linux/Ubuntu sont confrontés à ce problème -> (se connecter à Internet en utilisant un modem zte/etc .....) car les dongles modernes ont un stockage USB + modem + CD-ROM, le commutateur usb_modes blablabla ......... ..............
quel est mon problème? -> Je ne suis pas en mesure ** (parfois en mesure de) ** ** de se connecter à Internet avec ZTE (Reliance cdma) AC2739.
Comment Ubuntu détecte mon dongle USB? Ans: de 3 manières:
1) ne détecte pas le périphérique USB mais lsusb affiche le périphérique.
2) détecter le périphérique (1 cas sur 10 après l’insertion de l’USB), mais le gestionnaire de réseau ne le détecte pas comme connexion à large bande.
3) détecter le périphérique (1 dans 15 cas après avoir inséré l'USB) et également le gestionnaire de réseau le détecter comme connexion large bande -----> c'est le cas lorsque je suis capable de me connecter à Internet.
Journaux système pour les 3 cas:
Journaux communs (c’est ce que montrent les journaux système chaque fois que j’insère un dongle USB)

Si quelqu'un veut un fichier texte de tout le journal, faites le moi savoir. Ce problème se trouve dans de nombreux dongles USB. Si quelqu'un peut apporter une solution à ce problème, veuillez le faire. J'essaie de 3 jours j'espère que je vais obtenir une solution maintenant.
après analyse journaux système soigneusement cette solution a fonctionné pour moi
cause du problème: Plusieurs modes de dongles modernes.
Solution:
1.
gedit /etc/usb_modeswitch.conf
2.ajoutez ce code au commutateur USB diable en haut.
DisableSwitching = 1
3. l'enregistrer.
4.insert usb à nouveau
5.eject usd cdrom par un clic droit, éjectez-le
ou en utilisant.
Sudo éjecte/dev/sr1
6.Attendez 5 à 10 secondes (le temps de le détecter comme modem). 7. Allez maintenant au gestionnaire de réseau.
8.Le réseau Reliance sera répertorié dans le gestionnaire de réseau qui s'y connecte en créant une nouvelle connexion.
7. maintenant aller au gestionnaire de réseau
8.Le réseau Reliance sera répertorié dans le gestionnaire de réseau qui s'y connecte en créant une nouvelle connexion.
c'est tout
Reliance fournit également le logiciel d'interface utilisateur
installez-le simplement en utilisant
Sudo ./nom de fichier
l'exécuter en utilisant
Sudo ztemtapp
cela fonctionne pour moi.
J'ai eu un problème assez similaire avec mon modem USB ZTE et il s'est avéré qu'il était monté en tant qu'unité de CD.
Voici comment je le résous:
Étape 1: Utilisez lsusb pour vérifier que votre modem USB est détecté
sergiotca@sergiotca-Dell-System-XPS-L502X:~$ lsusb
Bus 002 Device 003: ID 8086:0189 Intel Corp.
Bus 002 Device 002: ID 8087:0024 Intel Corp. Integrated Rate Matching Hub
Bus 002 Device 001: ID 1d6b:0002 Linux Foundation 2.0 root hub
Bus 004 Device 001: ID 1d6b:0003 Linux Foundation 3.0 root hub
Bus 003 Device 003: ID 046d:c07e Logitech, Inc.
Bus 003 Device 009: ID 19d2:2000 ZTE WCDMA Technologies MSM

Bus 001 Device 002: ID 8087:0024 Intel Corp. Integrated Rate Matching Hub
Bus 001 Device 001: ID 1d6b:0002 Linux Foundation 2.0 root hub
Étape 2: Utilisez dmesg | tail pour savoir comment il a été détecté
sergiotca@sergiotca-Dell-System-XPS-L502X:~$ dmesg | tail
[ 6136.744009] usb 3-1: Manufacturer: ZTE,Incorporated

Étape 3: Utilisez sb_modeswitch pour changer le mode de votre modem USB en "l'éjectant" à l'aide du paramètre - K. Utilisez le fournisseur et l'ID de produit de votre propre modem (lsusb)
sergiotca@sergiotca-Dell-System-XPS-L502X:~$ Sudo usb_modeswitch -v 0x19d2 -p 0x2000 -K
[Sudo] password for sergiotca:

-> Run lsusb to note any changes. Bye!
Étape 4: Enfin, utilisez dmesg | tail pour vérifier que votre modem USB est passé en mode d’accès direct.
sergiotca@sergiotca-Dell-System-XPS-L502X:~$ dmesg | tail

Étape 5: Votre modem devrait maintenant être détecté par le gestionnaire de réseau.
