After installing Ubuntu, internet connection not found.
 
I just recently received Ubuntu CD and installed it. I don't know how to connect via internet. I tried to browse and familiarize the environment. I am using Huawei vodem (Vodafone Broadband) and connect the wireless connection but icon does not appear. Usually with Windows XP, the Vodafone Mobile Connect Lite automatically pop up and click the connect button but there is none in Ubuntu. Also, I tried to re-install the vodem ISP CD installer but it can't read the content. I'm at a lost, appreciate any help.

Welcome to LQ!!

First let's see if the Wireless card is being detected. Open a terminal and run these commands:

sudo ifconfig -a (look for a device like wlan0 or maybe eth1. Normally, the standard ethernet (wired) connection will be eth0)

sudo lspci (look for two different network devices--one standard ethernet, the other wireless)

sudo dmesg|grep keyword (replace "keyword" with something relevant from the lspci output)

If the wireless device (on the computer) is found in lspci, but NOT in ifconfig or dmesg, then it means you need to install a driver.


One way or the other, we need to know the details of both ends of your wireless internet setup---ie what is in the computer, and what is used for the access point.

That presumably is a setup disk for Windows--it's not going to work on Linux.

As you have internet access in some way, use google; results for Huawei linux

It might be quite scary for a new linux user, but if you don't understand something you can always ask.

You need a fairly new kernel to operate that modem; 2.6.21 and later seem fine. I don't know the version of the earliest kernel that will run that modem.

You need the 'usbserial' and 'option' drivers to operate the modem:
modprobe usbserial

If the usbserial comes up and you also see messages about 'option' then everything is OK. Otherwise, you need a newer kernel.

You can see if usbserial and option are already running:
lsmod|grep usb
lsmod|grep option

The device will be /dev/ttyUSB0 (there is a ttyUSB1, but ignore it - it's a stupid feature of the modem meant to provide some flash storage - but it doesn't work in Linux, and from what Vodafone say, it doesn't work in WinDuhs either).

So, you need to set up 'pppd' to call through 'ttyUSB0'. You need the 'novj' option to disable compression. To 'dial out' I think it's *99# or *99***# (the longer version is the 'roaming' version). You need a user name and password but they can be anything.

You can configure the modem with 'pppconfig'; it's pretty sensible.

I follow link http://www.ubuntulinux.org/wiki/DialupModemHowto and click Setup Huawei Modems.

The Huawei E220 can be a USB 'dongle' for HSDPA connection through the Vodaphone network.

Download vodafone-mobile-connect-card-driver-for-linux (in short, VMCCfl) :

https://forge.vodafonebetavine.net/f...x_1.99.17_i386 .deb

Click in the file to open it with GDebi.

Upon opening GDebi, there is an error message: Wrong Architecture
'i386'.

I have just intalled Ubuntu but till now can't connect the internet.

Any suggestion will be appreciated.

Thanks.

"Any suggestion will be appreciated."

All I can suggest is to follow my previous post. I have looked at the sites which you've followed and I am convinced that the information was posted by people who don't know what they're doing. There are also other posts here about configuring that modem; search for them.

These are the settings I use on a Vodafone (Hauwiaii - however you spell it) card and a verizon one in the states.

might be worth booting up from scratch with the vodafone one. I sometimes have to reboot to get it to work. something broken in the udev hotplug modules i think
