Reliance Net Connect on Ubuntu 9.04 by using ZTE MG880 Modem (without wvdial)

Hi All

If you google around for configuring your reliance USB modem on ubuntu 9.04 then almost all links will lead to wvdial configuration. But there
is also another way of doing it with out touching wvdial is by using pppconfig.

To avoid confusion and errors please copy and paste commands.Here we go...

1. Firstly we will have to find out modem vendor id and product id. Use the following command to find it.

sudo lsusb -v

You can see output like this...
Bus 005 Device 007: ID 19d2:fffd
Device Descriptor:
bLength 18
bDescriptorType 1
bcdUSB 1.01
bDeviceClass 0 (Defined at Interface level)
bDeviceSubClass 0
bDeviceProtocol 0
bMaxPacketSize0 16
idVendor 0x19d2
idProduct 0xfffd
bcdDevice 0.00
iManufacturer 1 ZTE, Incorporated
iProduct 2 ZTE CDMA Tech
iSerial 3 Serial Number
........

Note down id Vendor and id Product some where.

2. Loading kernal module with vendor id and product id.

sudo gedit /boot/grub/grub.cfg --->> for Ubuntu 9.04

In the grub.cfg file add the following lines at the end of kernal line (Not in the next line)

usbserial.vendor=0x19d2 usbserial.product=0xfffd (Replace the the values with your's)

### BEGIN /etc/grub.d/10_linux ### set root=(hd0,3)
search --fs-uuid --set 126317bd-2dd9-4016-8e65-df85fda33a34
menuentry "Ubuntu, linux 2.6.28-11-generic" {
linux /boot/vmlinuz-2.6.28-11-generic root=UUID=126317bd-2dd9-4016-8e65-df85fda33a34 ro quiet splash usbserial.vendor=0x19d2 usbserial.product=0xfffd
initrd /boot/initrd.img-2.6.28-11-generic
}
menuentry "Ubuntu, linux 2.6.28-11-generic (single-user mode)" {
linux /boot/vmlinuz-2.6.28-11-generic root=UUID=126317bd-2dd9-4016-8e65-df85fda33a34 ro single
initrd /boot/initrd.img-2.6.28-11-generic
}

3. Reboot/Restart your computer.

4. Close all terminal. Open new terminal and type

sudo pppconfig

in the new (below) window select Create and give ok...

Type provider name (say reliance) and give ok

Select Dynamic and give ok

Select PAP and give ok

Enter your Reliance Number and give ok

Password is same as your Reliance Number, enter it and give ok

Do not change Modem Speed

Select Tone and give ok

Enter #777 and give ok

Enter yes

Select Manual and give ok

Give your modem port. In my (most of the) case it is /dev/ttyUSB0

Now all set. Ensure Everything is fine. Select Finished then ok

Finally in the last wind select Quit and give ok

Now you have configured your modem successfully and all set to connect.

5. To establish internet connection type the following command in terminal...

sudo pon reliance

6. Ensuring connection is established use this command...

ifconfig
Now you should see entry like this...
ppp0 Link encap:Point-to-Point Protocol
inet addr:123.239.41.80 P-t-P:220.224.134.12 Mask:255.255.255.255

collisions:0 txqueuelen:3
RX bytes:2309338 (2.3 MB) TX bytes:731534 (731.5 KB)

Once the connection is established you can close the terminal.

7. To disconnect...

sudo poff reliance

Extra
In case if you want to monitor internet speed then install pppstatus package (sudo apt-get install pppstatus) and type sudo pppstatus in the terminal.

That's all I have to do get Internet running on my laptop
