    Question ZTE MF627/MF628/MF628+ Detected in 11.04 But Can't Connect to the Internet

    Hi!

    I'm using Ubuntu 11.04 since July (first time ubuntu and linux user) and I have this ZTE device MF627/MF628/MF628+. It can be detected in New Mobile Broadband Connection but it won't connect to the internet. Here are some info I think would help in troubleshooting this.

    in PPP Settings, Authentication method is just CHAP.

    This is working in Windows. I used hyperterminal to make it switch to modem mode instead of CD using these commands:

    AT+ZOPRT=5
    AT+ZCDRUN=8

    and added in /etc/init.d/rc.local the following:

    modprobe -r usbserial
    modprobe usbserial vendor=0x19d2 product=0x1402

    I have tried different settings in mobile broadband connection but it still won't connect to the internet. I suspect something wrong in the dmesg result but I don't know what to do next.

    Please help. I've been cracking this since last week. I'm using Ubuntu 11.04 with the latest updates.

    Thanks in advance

    I have a different ZTE modem (AC2726), but maybe this is related somehow.

    After a clean Natty install the nm-applet won't detect it automatically if the modem was plugged in during boot. I have to plug it out and plug it back in after login for nm-applet to be able to detect it. I didn't have to do that in previous Ubuntu version though, it was always detected and ready to connect in Maverick.

    Have you tried to do the same?

    Re: ZTE MF627/MF628/MF628+ Detected in 11.04 But Can't Connect to the Internet

    Thanks. Yes, I did. The device can be detected properly if I do that. But then after I try to connect it to the internet, it gets disconnected immediately. I also tried Gnome PPP to connect but after 36 seconds it disconnects. I was not able to view any web page.

    My Natty is a clean install.

    Any other ideas?

    to eisanchez:

    my take on things............

    you got all this.

    dmesg | grep ttyUSB

    [ 290.775988] usb 1-1.1: generic converter now attached to ttyUSB0
    [ 290.776184] usb 1-1.1: generic converter now attached to ttyUSB1
    [ 290.776354] usb 1-1.1: generic converter now attached to ttyUSB2
    [ 290.776568] usb 1-1.1: generic converter now attached to ttyUSB3
    ..........so the device is seen as a modem;

    so it should work;

    which country are you in? what network?

    You say

    but it won't connect to the internet.
    ..........tell us what happens........

    You also say

    in PPP Settings, Authentication method is just CHAP.
    ....... is it your provider gave you this? are you using a Virgin setup?

    Re: ZTE MF627/MF628/MF628+ Detected in 11.04 But Can't Connect to the Internet

    Hi pdc!

    First, thanks for the reply. Nice to see people in this community ready to help out.

    I'm from the Philippines under Globe Telecoms network.

    The CHAP thing I indicated is the settings I saw when I plugged it to a Windows machine. The authentication method selection is a dropdown list that is disabled so it means that CHAP is the only authentication I can have. It worked in Windows XP. I can connect to the internet in an instant.

    In Ubuntu 11.04, I did it this way:

    1. Boot without the modem attached.
    2. After Ubuntu is up, attach it.
    3. In a little while, when I click the network manager applet icon on top, the settings I made for the modem appears and click it to connect.
    4. After a few seconds: GSM Network: Disconnected. You are now offline message appears.

    Tried to reboot and do #1 and #2 above but this time connect using Gnome PPP. It connects but in 36 seconds it disconnects. I wasn't able to view a web page.

    I don't have an idea what's a Virgin setup, though.

    Before I made Ubuntu detect this device, I did the following:

    1. Plug it in a windows machine, open Hyperterminal and send the command:

    AT+ZOPRT=5
    AT+ZCDRUN=8

    2. I also did this:

    Code:
    sudo gedit /etc/init.d/rc.local
    and add these lines in the end

    Code:
    modprobe -r usbserial
    modprobe usbserial vendor=0x19d2 product=0x1402
    3. Reboot.

    4. Trigger the New Mobile Broadband Connection wizard. Device was detected fine.

    5. Move forward and select my country (Philippines), the telecom provider (Globe) and the plan (postpaid). All info was there already, including APN settings. I have changed the authentication method to CHAP only.

    6. Connect to the internet (but failed)

    In Windows, here are the settings I have seen:

    + DNS is set to auto
    + Authentication: locked to CHAP
    + Username and password: blank
    + LAN interface setup:
    IP address: 192.168.0.1
    Subnet Mask: 255.255.255.0

    The device is also a wireless LAN router that allows up to 5 connections.

    Did I missed something in the settings of the Mobile Broadband Connection? (I do not know where to indicate the other settings (aside from CHAP))

    Thanks in advance for all the help.

    all I can suggest is you look at sakis3g;

    if you find the website; an excellent alternative for dialling;

    sakis has a forum; and there are debug commands for running his programme;

    download the ubuntu variant; it installs quickly and well;

    it should install usb_modeswitch to cope with any modems;

    and will detect your network too.......see if it can work its magic
