Ubuntu Installation :: Modem Disconnects LTS 10.04 Live USB?
Oct 15, 2010
I use an analog modem and wifi to access the internet. I am using Ubuntu LTS 8.04 on a laptop and have an analog modem connected via USB serial cable. The dialup feature and the modem work flawlessly. I am testing LTS 10.04.1 on a live USB drive that I purchased preinstalled from On-Disk. On the live USB drive, I am able to get a dialup connection with my ISP long enough to pull up a web page with the browser. However, the analog modem disconnects within minutes with exit codes 16 or 17.
Man pppd:
16 The link was terminated by the modem hanging up.
17 The PPP negotiation failed because serial loopback was detected.
My questions are, how to do I track down the dialup setting(s), or file configuration(s) that is causing the disconnects? Is the problem likely due to a poorly worded AT modem command? I want to get this problem resolved before I proceed with upgrading from 8.04 to 10.04.1.

I have a Lenovo W510 Laptop with Ubuntu 10.04. The laptop has an on board Qualcomm 3g modem. I have managed to install the Qualcomm firmware and Network Manager detects the 3g device but when I try to connect it disconnects after a few seconds. My syslog has the error
Code: Got failure code 100: Unknown error

I've done a good few ubuntu installations for friends and colleagues and now my Dad wants in on the action. His PC is more than capable of running ubuntu 32 bit BUT I've hit a brick wall I've never come across before. I've burnt a CD image of the 10.04 iso from [URL] on my ubuntu box and for some reason, his PC just won't boot from it. If I select the option to manually select the boot source, all I see is the hardware monitor telling me things like CPU temperature. As for the Live USB - nothing whatsoever. Is it possible that I've managed to corrupt the iso file somehow?

Live CD: I dowloaded the ISO, burned it to CD, booted from this CD. It starts to load and I can see the purple background with the loading icons. Everything seems normal. But instead of ending up with the login screen, it ends up with a screen that says 'Please remove all bootup media and hit ENTER' or something like this. So I hit enter and then it shuts off my computer. That's it.
Live Stick: So I tried another option and created a stick with 'usb-creator.exe' that is on the CD. Then I start from that stick, but all I end up is a line of 'Syslinux bla bla copyright 20xx-2011'. That's it. Then it does nothing anymore. The cursor is blinking, but no prompt or whatsoever and keyboard input doesn't do anything.
Now something weird: When I insert Live CD and Live Stick at the same time and then boot my computer, then it boots into Ubuntu. Obviously it loads the first parts from CD and then the rest from stick. Because when I'm then in Ubuntu and try to format the stick, it says it can't do so, because there's system files from that stick in use.

find and install modem driver for the Alcatel X200 USB modem?
I've been all over the internet trying to locate Linux drivers but no success. Alcatel's website says is not supported, only in Windows. I'm sure there's gotta be a way to use the X200 in Linux.

I have this USB modem P300U(SIM600 chip based) which works fine under wind@ws because it has it's own driver, but the clever seller told me that it worked under Linux as well. It was with Redhat 8 but I couldn't get redhat 8 to download. And until now absolutely false.
I have Debian with Kernel 2.6.32-5-686 I just want to send sms through this modem. It's not recognized as modem I'm frustrated because it's not useful for me if it doesn't work on Linux I looked for info but I can't make it work. What I get in my debian is:
lsusb: Bus 002 Device 003: ID 10c4:ea60 Cygnal Integrated Products, Inc. CP210x Composite Device
dmesg: 9857.011649] usb 2-1: new full speed USB device using uhci_hcd and address 3

I have a Centos 5.4 server running kernel 2.6.18-164.11.1.el5PAE. It has an internal modem, and I need to be able to issue AT commands from a script to the modem. I need to simply dial a number and hang up. The relevant piece of my script is:
[Code]...
With an external modem, this works no problem. With an INTERNAL modem, the call never goes out. I fired up minicom to make sure the modem was working correctly, and if I issue those AT commands from within minicom, everything works great.
While minicom was running, I noticed a peculiar fact: WHILE minicom is running, the script works from the command line, and I can see all the AT commands and OK's in minicom, (minicom acts as a monitor). When I exit minicom, the script stops working. It appears minicom is creating a bridge between the com port and the modem itself. So, what is minicom doing that I'm unaware of?
The server's sole function is to run asterisk as a voicemail server (avaya wanted well into 6 figure territory to implement this....). This script is to dial an avaya FAC to turn the voicemail message lights on and off on the end users' phones.

I recently downloaded the latest minimal Ubuntu ISO from the official download page.
Is it possible to do a minimal install if I do not have Ethernet capable internet?
I use one of those 3G (cellular) USB modems from companies like Verizon. Basically, it's a cell-phone, with the phone component taken out.
I did something similar with Debian recently, but I had to install the kernel along with the 'dpkg' package, to the HDD. From there, I had to reboot into the core system, install the packages like ppp, wvdial, etc, and then continue with a fresh install of the rest of the system.
There doesn't seem to be a way for me to either install the core files to HDD, or install the internet connectivity packages in the live environment for my modem.

Just got back to attempting to play with 10.04 using its Live CD. It consistently goes to the "Log In" page and not the Live CD page on running. I saw a Post specifying a F key to be pressed on boot-up to get to the desired starting point some time ago, but did not write it down. Some advice did say press Any Key but this does not seem to do the job. Tried to use the search function here but no joy. Can anyone remember which F key? Note that as a check, I tried to use 9.10 Live CD and this worked fine, so it is not a machine problem.

I brought my netbook so I could continue to keep up with my homework, which amounts to a lot of typing and editing some TIF files.
Problem: Windows 7 isn't compatible with the router/modem I have access to, so I have no internet access in the apartment we've rented. I know that it works, because I'm using the apartment owner's ancient anemic desktop. Can't do homework on this though.
Problem 2: I have Windows 7 Starter, so I can't use compatibility mode, so I can't use Wubi.
Problem 3: I don't have an optical drive and have just a 512mb flash drive which may not work, so I'm not sure how to fix this.
Problem 4: I don't have a Windows 7 backup disc; never received one.
Problem 5: My dad works with copyright and intellectual property so he'd notice if I pirated Windows and would be extremely not okay with it.
I could probably buy a bigger flash drive if I really had to, hopefully they're not too expensive. I am most comfortqble with Ubuntu but I will use whatever will run the Gimp (or some TIF editor) and Firefox. I cannot afford to get 3 weeks behind on my homework.I've only been off the plane for a few hours and am trying to get used to the French keyboard, so I apologize for any typos that slipped through.

I've been trying out the netbook remix of 10.04 but I've been having some issues getting my Huawei modem to work. It detects the install cd and usb storage but it does not discover the modem.
This is the dmesg output after connecting the device:
Code:

I have been experiencing extensive networking problems with 10.04 and I was wondering what options there are for downgrading to a different (hopefully more stable) release. I cannot seem to get a wired connection direct from the modem. I don't know if its just me but I feel an operating system that can't do something simple like this (without extensive terminal codes and file edits etc) is not for me. Here are my system specs:
3.06 GHz E6600 Core 2 Duo
2x2GB GSKILL DDR2
MSI G41M4-F (Realtek Ethernet)
500 GB Seagate 7200
I also have a PCI NIC card Intel PWLA8391GTBLK GIGABIT 1PC I just want to connect to the internet in a hassle free manner. Is there a release of ubuntu that I can "downgrade" to that will make networking hassle free? I have previously used 8.04 on a different machine with no problems. Is downgrading from 10.04 trivial? I currently do not have any important files as this is a new build and file backup is not an issue. Is there anything I should keep in mind or be aware of before downgrading?

Being a former user of Fedora, i decided I'd like to give Ubuntu a try and install so i could switch from a windows environment for ruby on rails development.I downloaded the 10.10 ISO and burned the image to a DVD-RW (a cheap one) at 4xI'm deployed in afghanistan right now, and the only decent internet connection i have is in my office (i work in the network administration/operations office as a NETOPS NCO) and even then my downloads rarely exceed 50kbps. I also don't really have the best pick when it comes to writable media, i'm stuck with imation "plus" cd-r's and dvd-rw's.
After i burned the image to disc, i deleted the iso from my computer since i'm genereally not suppossed to keep personal files on work computers.When i boot to the disc it takes about 45 minutes on average to load into the live environment to do the install or try ubuntu, if i select try ubuntu it's another 10 minutes before it's done loading.The install is even slower, generally takes several hours to complete the install, once the install is complete and i select ubuntu in grub, i get a { DRDY ERR } ru When it tries to load ubuntu and kicks me back into the shell. Nothing appears to be wrong with my hard drive, checkdisk finds nothing.
General specs are:Intel Core i7 i7-720QM / 1.6 GHz 8GB DDR3 1333mhz ram2x 500gb hd'sBlu-ray/dvd/cd driveFull specs are at: the laptop is a g73jh-a1http://reviews.cnet.com/laptops/asus...-33950895.htmlI'm downloading the iso again and i'm going to try and burn it to a cd-r at the slowest possible speed, I'm mainly curious if it could be fualt of the disc i burned or if it has something to do with my computer.

I downloaded Ubuntu 10.10 2 days ago and tried to instal it on my:HP EliteBook 8540wIntel Core i7 740QMIntel QM57 Express8GB RAMnVidia Quadro FX 1800 with CUDA (1GB)Of course I went 64bit, but the Live CD wouldn't start. Instead I get some weird artifacts on my screen.I can see bits of my Windows-background with taskbar and some of the windows I was using earlier before restarting, like the download manager. If cold boot my PC I see black and white boxes with coloured dots on them.
Thus I thought of an issue with the 64bit architecture and possibly the grafics card too (the artifacts are clearly remnants of data from the VRAM)I tried the same with the 32bit version and got the same issue (indicating NO issue with 64bit, at least not directly).In the end, I installed Ubuntu from the alternate 64bit CD and now am stuck with a non-working installation of Ubuntu.I get some kind of error concerning pcieport (probably PCI Express).When I install Ubuntu on Virtualbox through Windows 7 however, I don't get any kind of issue (I'd still like to be able to run Ubuntu natively)Any idea on how to fix the problem?PS: I'm not very experienced with Linux, so if you ask me to go into console mode, please be detailed on what command I should input.
