Instalación dun Módem ADSL USB

Due to similar issues of that with a Winmodem, installation and configuration of a USBADSL modem may require lengthy procedures depending on the type of modem. For further installation information, pleas refer to https://help.ubuntu.com/community/UsbAdslModem. You will of course need another means of connection in order to review this documentation.

Dial-Up

Many people still access the Internet via a dial-up modem today. There are two basic types of dial-up modems in use.

Modems de software

Software modems, also known as Winmodems, are the type that are usually built into the system itself whether it is a desktop or a laptop. These modems are usually connected to a PCI port inside of the computer or a USB port outside of the computer. There are still quite a few of these types of modems that are not supported by Linux due to the type of binary driver or firmware they use. Winmodems supported in Linux are also known as Linmodems.

Módems de hardware

Os módems de hardware, ou módems de verdade, conéctanse normalmente ao porto serio do computador e procesan os comandos de módem crus, ao contrario dos Winmodems. Ainda que estes tipos de módem son cada vez máis raros, ainda destacan como o tipo de módem máis soportado polo Linux, xa que normalmente non precisan de controladores especiais.

The following sections will provide information on installation and configuration of your modem. The last section will provide configuration information on configuring a dial-up connection (see the section called “Dial-up Internet configuration”).

Instalación dun winmodem

Unfortunately due to the many different types of chipsets and the work involved in getting a Winmodem installed and functioning would be difficult to document in this one location. However, there are already documents out there to help you in your success at getting your Winmodem to work with Kubuntu. Not every Winmodem is guaranteed to work, but there are utilities out there to aide you in getting a supported Winmodem to work. The following links will hopefully provide the information needed to get your Winmodem working.

Instalación dun Módem de Hardware

Unlike software modems, or Winmodems, hardware modems do not need special software drivers. If your modem connects to your PC via the serial port, then you are in fact using a hardware modem. In order to configure your modem, you need to know which COM port, or serial port, you are using. The typical structure for COM devices is /dev/ttySx, where x is one less than the COM port number. For instance, if you plug your modem into COM port 1, then you would use the /dev/ttyS0 device. Port 2 would be /dev/ttyS1 and so on.

Dial-up Internet configuration

There are a few ways in order for you to get your dial-up connection working with the Internet.

Usar KPPP

KPPP - The dialer and front end for pppd which allows for interactive script generation and network setup. This is the preferred application in Kubuntu for dial-up modems. For more information on setting up KPPP, please refer to The KPPP Handbook.

Usar WvDial

WvDial - The command line Linux application for dial-up modems. This utility has been around almost since the invention of Linux itself. The following is a quick step-by-step procedure for using WvDial. Note that WvDial use is command line intensive.

  1. Open Konsole by going to Application LauncherSystemTerminal (Konsole).

  2. Escriba na liña de comandos sudo wvdialconf /etc/wvdial.conf e despois prema Enter.

    ERRO

    Se ve o erro seguinte é que o seu módem non se recoñece, non está en uso ou non está ben configurado.

    A editar "/etc/wvdial.conf".
    
    A procurar un módem nos portos serie.
    
    Modem Port Scan<*1>: S0 S1 S2 S3
    
    Desculpe, non se atopou nengún módem! Estáo a utilizar outro programa?
    Configurouno adecuadamente con setserial?
    
    Lea as Preguntas frecuentes en http://open.nit.ca/wiki/?WvDial
    
    Se ainda ten problemas, envíe unha mensaxe a<wvdial-list@lists.nit.ca>.
    
  3. If you did not receive the previous error message then you can move on and finish the setup by manually editing the /etc/wvdial.conf configuration file. To do so press Alt+F2, type kdesu kwrite /etc/wvdial.conf and press the OK button.

  4. After opening the wvdial.conf, insert your ISP information where needed. Other options may be needed in order to get your Winmodem to work correctly. This information is either available on the Linmodems website, or if you sent an email to their mailing-list, the information they provided to aide you in your setup. You can also type man wvdial.conf at the command prompt for further information.

  5. Garde e saia do ficheiro de configuración /etc/wvdial.conf.

  6. At the command line, try to dial out by typing sudo wvdial and pressing Enter.

Usar pppconfig con pon & poff

pppconfig is another command line option used to manage dial-up connections. This setup is not the easiest to configure, however it is a very flexible application. The pon and poff dial and hang-up when using the pppconfig utility.

If you are interested in using this utility, please refer to the wiki topic for pppconfig.
