Connect Internet at Ubuntu 8.04 by Using Handphone (LG KU250)

To detect your handphone, is it known by your Ubuntu, you can check it at System log while you insert it data cable to the USB Port. But before you do that, first open System Log Viewer by clicking [System]-[Administration]-[System Log]. At the “Message”, find the last line of the message.

Then, connect your Handphone LG KU250 to the USB port, and watch the message that will appear at the last line of the “message” part of the System Log Viewer.

Example of the message like this:

Jul 19 20:15:39 otak-korzzlet kernel: [ 62.851371] input: USB Optical Mouse as /devices/pci0000:00/0000:00:1d.2/usb3/3-1/3-1:1.0/input/input11

Jul 19 20:19:52 otak-korzzlet kernel: [ 102.725153] usb 1-2: configuration #1 chosen from 1 choice

Jul 19 20:19:53 otak-korzzlet kernel: [ 102.995205] cdc_acm 1-2:1.0: ttyACM0: USB ACM device

Jul 19 20:19:53 otak-korzzlet kernel: [ 102.997270] usbcore: registered new interface driver cdc_acm

Jul 19 20:19:53 otak-korzzlet kernel: [ 102.997278] /build/buildd/linux-2.6.24/drivers/usb/class/cdc-acm.c: v0.25:USB Abstract Control Model driver for USB modems and ISDN adapters

Pay attention to the message that I have give green colour. This message appeared when I connected my LG KU250 to the USB Port. And the message “Jul 19 20:19:53 otak-korzzlet kernel: [ 102.995205] cdc_acm 1-2:1.0: ttyACM0: USB ACM device” as a sign that Ubuntu has found he modem in your phone and known as ttyACM0. May be, it will have a little different with yours.

But, the important thing is, LG KU250 modem has known by Ubuntu 8.04.

Next, open trminal by clicking [Application]-[Terminal] and type ‘sudo su’ then give your root password to be a root. This time I work at a laptop (otak-korzzlet) with username zhumphallabux.

zhumphallabbux@otak-korzzlet:~$ sudo su

[sudo] password for zhumphallabbux: [give your password here]

The, type wvdialconf that followed by ENTER, so that it will appear message like these:

root@otak-korzzlet:/home/zhumphallabbux# wvdialconf

You can see that at the last three lines, system has found a modem at /dev/ttyACM0. Continue with configuration connection to the operator that you use by typing “gedit /etc/wvdial.conf” and ENTER, like this:.

root@otak-korzzlet:/home/zhumphallabbux# gedit /etc/wvdial.conf [Enter]

So that, it will appear a gedit window that have confoguration wvdial. Edit that configuration, based of your operation configuration. I have edited my wvdial configuration like next example. I am using “TELKOMFLASH” from TELKOMSEL Operator.

[Dialer Defaults]
Init1 = ATZ
Init2 = ATQ0 V1 E1 S0=0 &C1 &D2 +FCLASS=0
INIT3 = AT+CGDCONT=1,"IP","telkomsel"
Modem Type = USB Modem
ISDN = 0
Phone = *99***1#
Modem = /dev/ttyACM0
Username = telkomsel
Password = telkomsel
Baud = 460800

For the other operator, as Indosat with its im3, the differences only at INIT3 …… , iusername and password. Change it with INIT3= AT+CGDCONT=1,"IP","indosatgprs" and use “indosat” as user name and passsword for volume based or “indosat@durasi” for time based.

When you finished, save the change that you have done. Then Close wvdial configuration and go back to the terminal.

Now, you can connect to the internet, by typing “wvdial” on the terminal, so that it will appear messages like these:

root@otak-korzzlet:/home/zhumphallabbux# wvdial

AT&T’s Rivals Are Happy to Attack Over iPhone’s Network Woes

By LAURA M. HOLSON

Published: August 28, 2008

Apple sold more than a million iPhone 3G cellphones its first weekend — with some stores running out — and two million more since then, analysts say. But its July debut has been nothing less than a public relations headache for AT&T, with eager buyers complaining about dropped calls and poor network connections.

Some fingers point to Apple, which has tried to deflect the complaints. But many others point to AT&T’s cellular network. Whatever the source of the problems, AT&T’s rivals, long irritated by all the attention the iPhone has received, are on the attack and happy to exploit the discontent.

“A phone is only as good as the network it’s on,” said a full-page Verizon Wireless newspaper ad on Thursday, lobbing a shot at AT&T’s 3G, or third generation, high-speed network. A Verizon executive sent an e-mail to Wall Street analysts last week: “So much for a ‘new’ way of doing business at the old AT&T — your father’s phone company.”

For AT&T, the nation’s No. 1 wireless carrier, which exclusively offers the iPhone, the situation is especially tricky because the stakes are so high. Apple’s customers are largely forgiving of any foibles of the iPhone’s maker. But wireless companies like AT&T and Verizon are afforded no such a luxury. The 3G network is supposed to make it easier to surf the Web and watch videos online. With nearly 90 percent of all Americans owning a mobile phone, there is little room to grow and these rivals can ill afford to lose customers.

Further aggravating consumers, neither company has fully explained why calls were dropped and the network was slow. Theories abound, which is causing even more confusion — and finger-pointing. Is it a problem with the phone itself? Richard Windsor of Nomura Securities surmised in a research report that a new radio chip made by Infineon, a German chip maker, was to blame for the iPhone’s spotty service in areas where the cellular signal was weak.

Since Americans are not the only iPhone users complaining — consumers in the Netherlands reported iPhone problems too — some analysts think the iPhone is partly to blame. Apple offered a software fix to mixed reviews — but no explanation. Most analysts put the onus on AT&T. “If consumers are not getting the full 3G experience, that is not Apple’s fault,” said Akshay K. Sharma, a research director of carrier network infrastructure at the Gartner Group, a consulting firm.

Nielsen Mobile, a consulting firm, said that in tests in the 47 largest American cities, it was able to connect to 3G networks 93 percent of the time. (Its sample included all carriers.) By contrast, in the San Francisco area, where many of the iPhone troubles have been reported, that number was 87 percent.

Phil Marshall, of the research firm the Yankee Group, said the problem probably lies somewhere in between, in how the iPhone interacts with AT&T’s network and signals are transmitted and received.

AT&T’s growing pains with its 3G network might otherwise be overlooked if not for the popularity of the iPhone. (Verizon executives conceded they too had problems when data users increased use of their highest speed network.) AT&T’s 3G network includes 310 cities with 100,000 people or more, but it plans to add 40 cities by the end of the year.

“It’s hard to launch an iconic device like the iPhone on a network that it is not yet fully deployed,” said Mr. Marshall. “As they build these networks they will need to make more improvements or the complaints will persist.”

But there is a bigger issue at play too, Mr. Marshall said. “Both companies are accustomed to controlling all aspects of the delivery of its products,” he said. “It illustrates the culture clash, when you create an environment where you share the responsibilities between them. Then you have problems.”

Already there seem to be fissures in the relationship. Two camps are emerging at AT&T: those who think Apple is too controlling with information and those who think Apple can do no wrong, said two people who have talked to AT&T executives but who declined to be named because they were not authorized to speak on their behalf.

Jennifer Bowcock, a spokeswoman for Apple, said executives there declined to comment about consumer complaints. Bill Hogg, president of network services for AT&T’s wireless divisions, acknowledged the complaints, but said, “We don’t believe macro or global issues are causing the problems.”

He said the company had enough capacity on its 3G network to handle all of its iPhone customers, who tend to be heavy data users. But he too was reluctant to discuss AT&T’s relationship with Apple.

When asked if the recent software update was devised to fix poor 3G network reception, he said, “Apple does a lot of updates.” When asked why calls were being dropped, a publicist intervened in the interview: “We are not going to go into the details of what customers are talking about.”

Customers are more than happy to be heard. Benji Jasik, a product manager at a start-up in Palo Alto, Calif., said his new iPhone dropped calls several times on his commute between San Francisco and Silicon Valley.

Since he downloaded the software patch, he said has had fewer dropped calls, but network connections remain sluggish. “Everyone is interested in figuring out if this is an AT&T or an Apple issue,” he said. “I just want to know who to call to fix it.”

Verizon Wireless thinks that will give it the edge in getting consumers and analysts to believe its pitch: Verizon’s 3G network is better. For nearly a year, consumers have been gushing over the iPhone. Now it is Verizon’s turn. Gizmodo.com, a gadget Web site, this week posted an internal Verizon sales document entitled “3G iPhone Myths” that gave Verizon employees talking points. Mr. Sharma, the research director, said he recently met with Verizon executives who chided AT&T executives for their mishandling of the iPhone imbroglio. “They told us they’d rather miss a deadline than have a bad launch,” he said.

In the past two weeks a Verizon corporate communications executive, Jeffrey Nelson, has sent almost daily missives to analysts pointing out blog posts and news articles that take aim at AT&T, Apple and the iPhone. “Where is the recall?” said one e-mail from Aug. 19. “Where are the refunds? Or maybe toss in a free ring tone and a couple months of free service?”

“I get almost one a day,” said Mr. Marshall. “It’s almost like, hey, quit spamming me.”

Verizon executives are not apologizing. “As the market matures, every single customer is tougher to get,” said Anthony Melone, Verizon’s chief technology officer. “This environment is really competitive.”

Is Notebook A Better Choice Than Desktop?

By: Roberto Sedycias

If internet made the world a global village, then we might as well say that notebooks made it a global colony. With desktops, things were a click away from us; notebook shorted the distance. Now we can carry the global colony on our shoulder. High-end technology at your lap, perhaps, we need nothing to conquer the world of convergence. chnology at your lap, perhaps, we need nothing to conquer the world of convergence.

The great advantage of notebooks is that it gives us a sense of portability and mobility. Looking critically, portability is the only feature, a notebook has over desktops then why do we choose to go for a notebook? Notebooks can let you carry your work conveniently and you do not have to worry about all the wires, hardware and space required to keep a desktop. Also it's a matter of choice between work and home. You may want to work from home, when your baby or wife is ill. A notebook comes in handy then.

A notebook has a different role to play for different people, but it gives an incredible sense of freedom. Gone are the days when people walked around with pen and paper. All you need to do today to make notes it to buy a notebook. You may want to quickly write a email to a radio station, which is making noise in the name of music. You may want to sit in your neighborhood coffee shop and write a book or letter. But if you want to carry your notebook everywhere you go, you have to consider the weight of the machine too. A notebook weighs between 5 to 10 pounds; an ultralight model is even lighter. Whereas, a desktop computer, with its standalone CPU, monitor, and keyboard, weighs in at about 70 pounds. A notebook takes much lesser space too and is very convenient.

Some of the most famous notebooks are Sony Vaio, Apple MacBook, Dell Latitude, Toshiba, HP. Also there are many affordable versions of notebooks marketed by companies like Fujitsu, Panasonic, IBM, Asus and etc.

Let's look at a scenario where at a school, students are quietly seated at their desks and working on a class assignment with no teachers to guide them. It's real, and is happening in many schools around us. Now, we don't have to mourn looking at our tiny ones carrying pounds of baggage in their backs. Notebook has it all, from their books to assignment copies.

When we look at the productive side of the picture, we would promptly realize that a notebook is always a wise choice for an employer too. It makes his or her employees to achieve more productivity at work. It saves critical office space. At any crucial moment, a notebook can help you to do the work, even when you are not physically present in the office. When the traffic is high, and your boss is waiting for presentation in a conference room, a notebook comes to the rescue. A desktop PC does not give all this freedom for a good worker.

A research says that employees with notebooks work more than those companies with desktop PCs. A notebook enables you to work from anywhere, while traveling, from a beauty parlor, or while waiting for someone at a shopping mall. And the only disadvantage a notebook has is its safety, unless you doubly assure it from theft. It's easy to pick and elope for anyone at a busy commercial place. So, ensure the safety of your costly gadget that makes you feel the world is at your feet and enjoy the power of technology.
