Rebin, The sl-modem-daemon_2.9.10+2.9.9d+e-pre2-5ubuntu4_i386.deb installed an older version 2.9.9 slmodemd. This will be shown by: $ slmodemd --version. Do $ sudo mv /usr/sbin/slmodemd /usr/sbin/slmodemd.2.9.9 Then install the version 2.9.11 slmodemd from the SLMODEMD.gcc.4.2 package. Check with: $ slmodemd --version which should show version 2.9.11 Do $ sudo gedit /etc/default/sl-modem-daemon to change SLMODEMD_COUNTRY=USA to SLMODEMD_COUNTRY=IRAN Make sure that the snd-intel8x0m driver is loaded with: $ lsmod | grep intel8x0 which should both snd-intel8x0 and snd-intel8x0m loaded. Then you can: $ sudo /etc/init.d/sl-modem-daemon for instructions. Then $ sudo /etc/init.d/sl-modem-daemon restart this will also run automatically on bootup also, through the slmodemd -c IRAN --alsa modem:1 so it needn't be manually done. So just try: $ sudo wvdialconf /etc/wvdial.conf and proceed from there.
