Dialup Connection

If you use a dialup connection with your computer, you will use KPPP. Click KMenu -> Internet -> (Connection ->) KPPP to define a connection, test that the modem is working, and dial your ISP.

Troubleshooting

Can't connect
1.First, make sure you know that your modem is compliant with MEPIS. The easiest way to do this is to run the package scanModem by downloading and following directions from this site to use the ScanModem utility.
2. If it is supported, then use KPPP to try to select different devices (/dev/modem, /dev/ttyS0, etc.) from the pull-down menu.
3. Open KPPP, click on the "Customize pppd Arguments" button and add the argument

call kppp-options

when you are setting up your dialup account details in KPPP's Accounts tab.
4. If you still have problems, open a terminal, become root, and type:

kwrite /etc/ppp/peers/kppp-options

--Check that there is no comment marker "#" in front of "noauth"
--Check that there is no comment marker "#" in front of the line with your ISP password
5. Try uncommenting the "noauth" line in the /etc/chatscripts/pap file, and changing the "auth" to "noauth" in the /etc/ppp/options file.
6. If all else fails, use gppp instead. If you have to download the files on another system, you will need

gnome-ppp (version 0.3.23-1)
libuniconf4.4 (version 4.4.1-1.1)
libwvstreams4.4-base (version 4.4.1-1.1)
libwvstreams4.4-extras (version 4.4.1-1.1)
libxplc0.3.13 (version 0.3.13-1)
wvdial (version 1.60.1+nmu2)

Can't communicate when connected

Wireless Modems

Internal

Some computers contain inexpensive internal modems that are designed only for use with MS-Windows. These are called winmodems or softmodems. MEPIS includes drivers for some winmodems.

Sometimes a driver will be available on the internet but be forewarned: these drivers tend to be difficult to install manually.

Drivers
  • Some native drivers (e.g., bcm43xx) are supplied with the Linux kernel
  • Windows drivers can be used with Ndiswrapper. A number of the most common are supplied with MEPIS, and others can often be loaded with the same application.
  • Another method of installing drivers is to use Linuxant

External

Serial modems: many work out of the box with MEPIS.

USB modems: usually show up on the rausb0 interface. Some drivers are available with MEPIS that may work, check the Linux Wireless LAN support link below. If not, then Windows drivers can be used with Ndiswrapper. If buying new, it's often a lot easier with a regular internal or serial external modem.
