I have just installed Ubuntu 12.04 on a separate partition on my hard drive so I can dual boot to either Windows 7 or Ubuntu.
I am living in Japan and so I'm using a mobile broadband USB device called "Softbank C02LC".
By default it seems that this device isn't recognised so I did the following:
Terminal:
sudo su
nano /usr/bin/usbModemScript
Nano:
#!/bin/bash
echo 1c9e 9900 > /sys/bus/usb-serial/drivers/option1/new_id
Terminal:
chmod +x /usr/bin/usbModemScript
nano /etc/udev/rules.d/option.rules
Nano:
ATTRS{idVendor}=="1c9e", ATTRS{idProduct}=="9900", RUN+="/usr/bin/usbModemScript"
ATTRS{idVendor}=="1c9e", ATTRS{idProduct}=="9900", RUN+="/sbin/modprobe option"
which made the device visible from the network manager etc.
However even though I set up my details correctly when I created a new connection (Correct username, APN etc) as soon as I try to connect it almost immediately disconnects.
Because of this I then followed the instructions at this site: http://debugitos.main.jp/index.php?Ubuntu%2F%A5%E2%A5%D0%A5%A4%A5%EB%A5%A4%A5%F3%A5%BF%A1%BC%A5%CD%A5%C3%A5%C8
And I ended up using the c02lc_connect script at the bottom of the page to connect to the internet.
The file contains the following bash script:
#!/bin/sh
usbinterfece=/dev/ttyUSB2
VID=1c9e
PID=9900
WRONG_PID=f000
LSUSB=/usr/sbin/lsusb
GREP=/bin/grep
MODPROBE=/sbin/modprobe
SWITCH=/usr/sbin/usb_modeswitch
SWITCH_D=/etc/usb_modeswitch.d
WVDIAL=/usr/bin/wvdial
SLEEP=/bin/sleep
SUDO=/usr/bin/sudo
WHICH=/usr/bin/which
switch_config="$SWITCH_D/$VID:$WRONG_PID"
if ! [ -x $WVDIAL -a -x $SWITCH ]; then
echo "Install wvdial and usb_modeswitch."
exit 0
fi
check_usb() {
local vid="$1"
local pid="$2"
($LSUSB | $GREP "$vid:$pid")
}
if ! (check_usb "$VID" "$PID"); then
echo "Cannot find modem device..."
if (check_usb "$VID" "$WRONG_PID") && ( [ -f "$switch_config" ] ); then
echo "The device is attached but its mode is wrong."
echo "Try usb_modeswitch..."
$SUDO $SWITCH -c "$switch_config"
$SLEEP 1
if (check_usb "$VID" "$PID"); then
echo "Successfully switched the mode."
else
echo "Failed to switch the mode..."
exit 1
fi
else
exit 1
fi
fi
if [ ! -c "$usbinterface" ]; then
$SUDO $MODPROBE usbserial vendor=0x$VID product=0x$PID
$SLEEP 2
fi
$SUDO $WVDIAL
which works completely fine - no problems what-so-ever.
But we also have 1 more laptop here which I need to share the internet connection with.
In Windows 7 I do this with the Connectify program, and in Ubuntu I have seen that you can do things like set up hotspots etc.
But because I am using WvDial I am not sure how I would share the internet.
I am only beginning to use Ubuntu but unfortunately until I can figure out how to share the internet over WiFi when connected via WvDial I have to stick with Windows.
If you have any ideas on how to do this it would be much appreciated!
