WiFi – How to Share USB Modem Dongle Internet

Note:- Data cards are automatically detected in newer version of ubuntu. You just have to wait for detecting it and then you can configure it. Use this method only when your data card is not detected by default.

Plug in your modem. Let it be recognized as a flash drive. Once that is done do

1) Open terminal and type

lsusb.

The output will be something like this:

Bus 001 Device 001: ID 1d6b:0002
Bus 003 Device 001: ID 1d6b:0001
Bus 002 Device 002: ID 12d1:140b Huawei USB Device
Bus 002 Device 001: ID 1d6b:0001

If you have same ID 12d1:140b Hwawei USB Device> follow the same instruction below

Now the first number here is the vendor id (0x12d1) and the second one (0x0140b) is product id. These numbers will differ depending on the make and model of your modem.

2) now type in terminal

modprobe usbserial vendor=0x12d1 product=0x140b

**optional:{ only if terminal asks for permission or are you root something.. then type

sudo modprobe usbserial vendor=0x12d1 product=0x140b

enter your password ...

}**

Note down ZTE WCDMA Technologies device id and product id on a piece of paper.

In my case it was 19d2:ffe9

Here 19d2 is device id and ffe9 is a product id.

Create new file using following file.

sudo nano /etc/udev/rules.d/90-zte.rules

Enter following code. [ everything is one line ]

SUBSYSTEM=="block",SUBSYSTEM=="scsi",ATTRS{model}=="USB Storage FFE9",ACTION=="add",RUN+="/sbin/modprobe usbserial vendor=0x19d2 product=0xffe9"

and save this file. Please remember to change the vendor id and product id as noted down on piece of paper earlier.

Now give following command and press return.

sudo /sbin/modprobe usbserial vendor=0x19d2 product=0xffe9

On command prompt type following command.

sudo wvdialconf /etc/wvdial.conf

This will create wvdial.conf file in your /etc directory.

edit this file using following command.

sudo nano /etc/wvdial.conf 

remove ; before username and password.

username = your 10 digit mdn number
password = your 10 digit mdn number

save this file.

Now you can create a connection in network management under Mobile Broaband

Gve anyname for the connection say "Reliancenetplus"

Number should be #777
Username is : mdn number
password is : mdn number 

• mdn number is like your mobile number in 10 digit. Save this connection.

Disconnect your earlier connection using wired or broadband connection.

From network manager you will now see Reliancenetplus . Just click.

You are now connected...
