I have Ubuntu 6.10 on a Dell Inspiron 5100 laptop. After some configuration,
the internal modem mostly works using ALSA drivers and the smartlink daemon
from the Ubuntu repositories.
While the modem works well upon startup, it fails to connect to the Internet
after I suspend or hibernate the system. Wvdialconf still detects the modem
fine. "$ sudo wvdial" begins the connection process, but brings back a "No
Carrier" error and goes into an endless "Trying again" loop until I kill it
with ctl-c.
I assume something just needs to be re-loaded, but don't know what.
Rebooting fixes the problem, but is not ideal.
I have looked all over for a solution but have as yet been unsuccessful.
I have attached three files:
1) my ModemData.txt
2) my wvdial.conf
3) the log from wvdial when I attempt to connect after suspending or
hibernating the system.
Any help or guidance about where to look for answers would be appreciated.
Thanks:
Matt

a bootup process, but then enabled later. If modem drivers load
but the modem is not responsive, read Bootup.txt about possible fixes.

ALSAversion 1.0.11
For candidate modem in PCI bus: 00:1f.6
Class 0703: 8086:24c6 Modem: Intel Corporation 82801DB/DBL/DBM
Primary PCI_id 8086:24c6
Subsystem PCI_id 134d:4c21 , 134d is an ALSA compatible identification
Softmodem codec or Vendor from diagnostics: SIL21, a Pctel type.
from Archives: SIL21, a Pctel type.
Lacking a dsp (digital signal processing) chip, the modem is a software
intensive or "softmodem" type. Its primary controller manages the traffic
with the CPU. But the software needed is specified in the Subsystem.
-----------------------------------------
Support type needed or chipset: slmodemd
An ALSA (Advanced Linux Sound Architecture) modem driver: snd-intel8x0m
provides Low Level support enabling contact with the modem hardware.
For all BUT Conexant chip soft modems (using hsfmodem software)
complementary High Level support is through a Smartlink utility: slmodemd
Download from http://linmodems.technion.ac.il/packages/smartlink/
the package SLMODEMD.gcc4.tar.gz having a compiled slmodemd. Unpack under
Linux with:
$ tar zxf SLMODEMD.gcc4.tar.gz
and read instructions therein. But briefly, the modem is setup with command:
sudo slmodemd -c YOUR_COUNTRY --alsa modem:1
reporting dynamic creation of ports:
/dev/ttySL0 --> /dev/pts/N , with N some number
Read Smartlink.txt and Modem/YourSystem.txt for follow through guidance.
Already loaded into the kernel is snd-intel8x0m and audio drivers it depends
on,
