We are going to connect our Ubuntu system to Internet using a Sony Ericsson K530i phone via a usb cable.
First of all we switch on our phone, we insert the pin number and then connect the usb cable that came with the phone to our K530i and to our computer.
A menu presenting three choices will appear on the phone screen:
- File transfer
- Phone mode
- Print
We select
Phone mode.
Now our phone is ready to use the usb cable.
There are
two ways to connect to Internet via USB:
- Emulating a ethernet device through a usb cable.
- Using the K530i mobile phone as a usb serial modem.
EMULATING A ETHERNET DEVICE THROUGH USB CABLE
Our system Linux kernel has to already be compiled with
cdc_ether module support. This module performs the emulation.
Let's
configure our phone, we go to:
Menu->Settings->Connectivity->USB->USB Internet->USB data accounts
and select our Internet ISP provider account.
If there is not an already configured account we shall create a new account:
Menu->Settings->Connectivity->Data comm.->Data accounts->New account
Some
APNs from Spanish Internet providers are:
Movistar: movistar.es
Vodafone: ac.vodafone.es
Yoigo: internet
Orange: internet
Usually user and password are not needed.
At the end, we establish the connection:
Menu->Settings->Connectivity->USB->USB Internet->Turn on
To check what has happened, we open a console and execute:
$ifconfig
An interface like
usb0 with its
IP address correctly configured will appear.
When we finish navigating, we switch off the connection:
Menu->Settings->Connectivity->USB->USB Internet->Turn off
