Hi, I did go thru most of this thread, I got my 3G Novatel U630 working in Suse 9.3 with Kinternet with out to much hassel... Didn't even look at wvdial.

Inserted the card went to YAST and configured it as a modem with a second provider.
add a few strings in config file.
 
Hey !!DV!! Just Murphys law isn't it? Would you mind posting the config changes you made?

Tazz, How do I go about using AT+CSQ to get a signal strength output?
 
Suse 9.3 Kinternet

Here we go...

Insert Card (nothing happend ...no beep, no lights..)
restart pcmcia (rcpcmcia restart)

Open Yast, go to Network Devices.... next to Modem...
It is detected as a AT Modem.. Click on cofigure...
Go theu the motions as normal...
Phone number *99***1# any username and no password..

Config files...
/etc/sysconfig/network/
ifcfg-modemX (X is a number asigned by Yast to config file)
BOOTPROTO='none'
DIALCOMMAND='ATDT'
DIALPREFIX=''
DIALPREFIXREGEX=''
INIT1='ATZ'
INIT2='AT Q0 V1 E1 S0=0 &C1 &D2 +FCLASS=0'
INIT3='AT+CSQ' #### Report signal strength see below....
INIT8='ATM0'
INIT9=''
MODEM_DEVICE='/dev/ttyS0'
NAME='AT Modem'
PPPD_OPTIONS=''
PROVIDER='provider1'
SPEED='115200'
STARTMODE='manual'
UNIQUE='Fyby.KM1shMXflFC'
USERCONTROL='yes'

/etc/sysconfig/network/providers/
provider1
ASKPASSWORD='no'

ISDNSUPPORTED='no'
MODEMSUPPORTED='yes'

PROVIDER='VodaFone'
STUPIDMODE='no'
USERNAME='internet'

After all this you select the correct modem fron list by right click on Kinternet Icon and then dail...
then click on view log you will see something similar to this

Hey agent,

I still need to do some work on the AT+CSQ command and how to work it nicely...I am thinking of something like - show_signal.sh which will report something like:

4/5 - Good Signal, enjoy the speed :)

Laterz !!!

When wireless providers refer to i.e. 64k, do they mean 64 kilo bits or 64 or kilobytes, can someone please assist.
 
Thanks, so I presume if they say up to 1MB to refer to mega bits? :confused:

Hey jbad,

Normally kilobits :)

Linux usage

Hello Everyone,

I use this "quick-and-dirty" script to show usage under Linux. I am sure it can be made better, but it was a 2 min job. I have this in my cron jobs that calcs usage for the day, then rotates the log.

I have added a line to my /etc/syslog.conf:

Code: 
*.*                /var/log/all.log
Restart syslog after that. I also have debugging on in /etc/ppp/options:

Code: 
debug
kdebug 4
calc_usage.sh

Code: 
#!/bin/bash
cat /var/log/all.log | grep pppd | grep Sent | gawk -F\  '{print $7"+"}' | xargs > /tmp/sent
echo "0" >> /tmp/sent
echo -n "Sent Total : " && cat /tmp/sent | xargs | bc
cat /var/log/all.log | grep pppd | grep Sent | gawk -F\  '{print $10"+"}' | xargs > /tmp/recv
echo "0" >> /tmp/recv
echo -n "Recv Total : " && cat /tmp/recv | xargs | bc
rm -rf /tmp/sent
rm -rf /tmp/recv

Demo:

localhost tests # ./calc_usage.sh
Sent Total : 9891729
Recv Total : 10027875

Enjoy !!!
 
New version of calc_usage.sh

Hello All,

i have just made a new version of the script - It will now keep track of the sessions in a file, easy to view easy to manage.

You can also edit the first three lines to make it work for you :)

Enjoy !!!

calc_usage.sh
Code: 
#!/bin/bash

logfile="/var/log/all.log"
tempfile="/tmp/logs"
datafile="/tests/data_usage"

cat $logfile | grep pppd | grep Sent > $tempfile
cat $datafile >> $tempfile

cat $tempfile | grep pppd | grep Sent | sort | uniq > $datafile

cat $datafile | gawk -F\  '{print $7"+"}' | xargs > /tmp/sent
echo "0" >> /tmp/sent
echo -n "Sent Total : " && cat /tmp/sent | xargs | bc
cat $datafile | gawk -F\  '{print $10"+"}' | xargs > /tmp/recv
echo "0" >> /tmp/recv
echo -n "Recv Total : " && cat /tmp/recv | xargs | bc
rm -rf /tmp/sent
rm -rf /tmp/recv
rm -rf $tempfile

Please advise How to get working

Hey bank_nut,

When last did you try - I also saw these problems on Sat. and reported them to Vodacom. All seems well now...

You are getting the wrong DNS info. please paste the output of:

Code: 
cat /etc/ppp/options

Laterz !!!
 
Please review and advise me
I still get problems connecting i succed one in 8 times
Maybe I should use a fixed name-server IP

regards
Nico
:(
===================here is the settings
noipdefault
noauth
crtscts
lock
modem
asyncmap 0
nodetach
lcp-echo-interval 30
lcp-echo-failure 4
lcp-max-configure 60
lcp-restart 2
idle 600
noipx
file /etc/ppp/filters

should use
linux:~ #

regards
Nico

ooooppppsssss - sorry about that - bit of a big file there :)

Anywayz - all seems ok then, what you might wanna do is run that command at the top grep -v ^#... and trim that file down - doesn't make a diff though.

If you really wanna see some wierd numbers and stuff, uncomment the debug lines and make kdebug 4. This will print the neg. between your card and Vodacom into syslog - some neat info there !!!

Enjoy !!!
 
Hi

Unsure if this is the right place but I have 3G card from a Norwegian provider (Netcom) that's not getting detected correctly. It's an Option card model # GT 3G Quad.

uname -a
Code: 
Linux buddy 2.6.12-suspend2-r6 #6 SMP Tue Sep 27 20:00:52 CEST 2005 i686 Intel(R) Pentium(R) M processor 1.80GHz GenuineIntel GNU/Linux

I'm running Gentoo with UDEV. PCMCIA and hotplug is installed.

When I insert the card dmesq reports:

Code:

The device does not get associated with any serial device!

I've tried to manually modprobe serial_cs and usbserial (along the lines of this howto) but neither claim the device.

Here are the relevant parts of my kernel config with regards to serial drivers:

Code: 
CONFIG_SERIAL_8250=y
CONFIG_SERIAL_8250_CONSOLE=y
CONFIG_SERIAL_8250_CS=m
CONFIG_SERIAL_8250_ACPI=y
CONFIG_SERIAL_8250_NR_UARTS=4
CONFIG_SERIAL_CORE=y
CONFIG_SERIAL_CORE_CONSOLE=y
CONFIG_USB_SERIAL=m
CONFIG_USB_SERIAL_GENERIC=y
CONFIG_USB_SERIAL_IPW=m
CONFIG_USB_SERIAL_OPTION=m

Am i missing some kernel stuff here?
