Amir, scanModem reports that your modem is supported through hsfmodem drivers from linuxant: Predictive diagnostics for card in bus 01:01.0: Modem chipset detected on NAME="Communication controller: Conexant Systems, Inc. HSF 56k Data/Fax Modem " CLASS=0780 PCIDEV=14f1:2013 SUBSYS=155d:6793 IRQ=5 HDA2=00:1b.0 IDENT=hsfmodem Driver=hsfmodem-drivers For candidate modem in: 01:01.0 0780 Communication controller: Conexant Systems, Inc. HSF 56k Data/Fax Modem Primary device ID: 14f1:2013 Support type needed or chipset: hsfmodem Writing DOCs/Intel.txt For owners of a Dell PCs with Conexant HSF modems, a driver source package with full speed enabled is available, but requires driver compiling. Read DOCs/Conexant.txt For all code packages from Linuxant.com, either a driver set matching the boot kernel will be installed, or the drivers will first be compiled and then installed. The expert on modem software for Linux is "Support (Jonathan)" <modem.support@xxxxxxxxxxxx> From http://www.linuxant.com/drivers/hsf/full/downloads-ubuntu-x86.php download hsfmodem-7.80.02.06full_k2.6.32_21_generic_ubuntu_i386.deb.zip Under Linux unpack with: $ unzip hsfmodem*.zip Then install with: $ sudo dpkg -i hsfmodem*.deb Subsequently, the modem should be found with $ sudo wvdialconf /etc/wvdial.conf Edit in your personal information with: $ sudo gedit /etc/wvdial.conf and try dialing out with: $ sudo wvdial. See DOCs/Testing.txt for details. The above instructions were good before but now you will need to proceed to download driver below: Since the above referenced package is not there, you will need a generic source package and build the driver yourself: http://www.linuxant.com/drivers/hsf/full/archive/hsfmodem-7.80.02.06full/hsfmodem_7.80.02.06full_i386.deb.zip Read the instructions here: http://www.linuxant.com/drivers/hsf/install.php METHOD B: DEBIAN PACKAGE (*.deb) If you have obtained the driver package in DEBIAN format: 1. install the package with "dpkg -i hsfmodem_{version}_{arch}.deb", if apt-get or some other tool hasn't already done it for you. 2. if necessary, run "hsfconfig" to complete the installation, enter license information, or to change your modem's configuration. If you need to rebuild the Debian generic package from source, you can get the TAR package, and from the top directory run: "make debdist". A pre-compiled DEB package for the currently running kernel can be built using "make debprecomp" instead.
