Install ZTE C261 as Modem on Ubuntu Karmic (9.10)

I already upgrade my OS and now use Karmic. On Jaunty, I modify line of menu.lst on /boot/grub, but there is any changes on Karmic, so i want to write it down here since Karmic was not use menu.lst any longer.

This method is commonly used to mount USB on first startup. Other methods are also applicable, such as usbserial "usbserial.vendor=0x05c6 usbserial.product=0x9004" or other.

fist: check the number of vendor and product of your modem, in this case i use ZTE C261 as Modem.

root@leptop# lsusb
Bus 004 Device 001: ID 1d6b:0001 Linux Foundation 1.1 root hub
Bus 003 Device 001: ID 1d6b:0001 Linux Foundation 1.1 root hub
Bus 001 Device 002: ID 064e:a101 Suyin Corp. Acer CrystalEye Webcam

Bus 007 Device 001: ID 1d6b:0001 Linux Foundation 1.1 root hub
Bus 006 Device 004: ID 05c6:9004 Qualcomm, Inc.

Bus 005 Device 001: ID 1d6b:0001 Linux Foundation 1.1 root hub
Bus 002 Device 009: ID 0930:6544 Toshiba Corp. Kingston DataTraveler 2.0 Stick (2GB)
Bus 002 Device 001: ID 1d6b:0002 Linux Foundation 2.0 root hub

second : edit your grub menu to recognize your USB device. Edit on /etc/default/grub, and changed it, see on source bellow.


root@leptop# vim /etc/default/grub
GRUB_DEFAULT=0
#GRUB_HIDDEN_TIMEOUT=0
GRUB_HIDDEN_TIMEOUT_QUIET=true
GRUB_TIMEOUT=10
GRUB_DISTRIBUTOR=`lsb_release -i -s 2> /dev/null || echo Debian`
GRUB_CMDLINE_LINUX_DEFAULT="quiet splash usbserial.vendor=0x05c6 usbserial.product=0x9004"
GRUB_CMDLINE_LINUX=""

last : update your grub by running update-grub

root@leptop # update-grub
Generating grub.cfg ...
Found linux image: /boot/vmlinuz-2.6.31-14-generic
Found initrd image: /boot/initrd.img-2.6.31-14-generic
Found memtest86+ image: /boot/memtest86+.bin
done



okay, now you need to restart your computer, and you can use this device to make ppp connection via wvdial or other software.

At the startup,  you may need to run modprobe to load usbserial module to Linux kernel, and wvdialconf to create default configuration file of wvdial so that you can edit this file, as shown bellow :

root@leptop # modprobe usbserial vendor=0x05c6 product=0x9004
root@leptop # wvdialconf
root@leptop # vim /etc/wvdial.conf 

The wvdial should be like this :

[Dialer Defaults]
Init1 = ATZ
Init2 = ATQ0 V1 E1 S0=0 &C1 &D2 +FCLASS=0
Baud = 460800
Idle Seconds = 300
Stupid Mode = 1
Compuserve = 0
Asl Password = 0
FlowControl = CRTSCTS
Dial Command = ATDT
Modem Type = Analog Modem
New PPPD = yes
Modem = /dev/ttyUSB1
ISDN = 0
Phone = #777
Password = smart
Username = smart

As default, this connection will reset every 50 minutes, so you also need to change value of lcp-echo-failure, here is my lcp-echo-failure value :

cat /etc/ppp/options | grep lcp
# lcp-echo-failure option to detect that the peer is no longer connected.
lcp-echo-interval 30
# option requires a non-zero value for the lcp-echo-interval parameter.
lcp-echo-failure 9999994

    Maaf mas, karena bhs inggris sy nggak bagus, jd pakai bhs ibu saja :). Semua sudah dipraktekan dan berjalan lancar

    Saya nanya dikit mas, mau belajar maklum masih newbie
    beda 'mount usb' (menambahkan baris usbserial.vendor=0x05c6 usbserial.product=0x9004)
    dengan nge'load usbserial module' ($sudo modprobe usbserial vendor=0x05c6 product=0x9004) apa mas?? gunanya??

    Soalnya di tempat saya, setiap komputer nyala/restart, perintah modprobe wajib sebelum connect ke jaringan

    Sorry banyak nanya
    Thanks sebelumnya

    Tanya mas, saya udah lakuin hal di atas, tapi masih bingung juga. saat aku ketik "vim/etc/default/grub" terus cara ngubah (edit)nya di terminal gimana? aku enter aja tetep ga bisa edit. trus kalo udah nge-save nya gimana biar terminal kembali ke root@laptop#

    @CruM: sebenernya sih sama aja, ide nya sama sperti versi Hardy: dia load module nya di awal restart nah makanya di masukkan dalam grub nya. tp kadang2 dia gak bs, jadi perlu manual sudo modprobe itu.

    @awawi: ngedit nya tergantung pk editor apa ?, kalau pake vi atau vim :
    tekan ESC + i => untuk insert
    klo mau save ESC + : + wq => untuk save

    tambahan :
    1. di katakan dia kadang2 bisa kadang2 gak bisa itu mungkin krn setiap kali kita update maka dia akan buat update grub nya, jadi gak di load yg awal di buat.

    2. kalau dengan konfigurasi di atas kok masih suka DC ketika 50 menit, maka perlu di buat options per link yg ada, contoh kalau di saya ada di ttyUSB1, maka buat file yg di letakkan di /etc/ppp/options.ttyUSB1

    lcp-echo-failure = 99990000
    lcp-echo-interval = 1000
    idle = 999999999
