USB Modem Configuration

Follow the steps mentioned below to configure internet connection using USB modem

1) Insert your usb modem and observe your /var/log/messages log file, you should see something like

Dec 11 16:44:56 poison kernel: ohci_hcd 0000:00:13.0: wakeup
Dec 11 16:44:56 poison kernel: usb 1-3: new full speed USB device using ohci_hcd and address 2
Dec 11 16:44:56 poison kernel: usb 1-3: new device found, idVendor=1004, idProduct=6000
Dec 11 16:44:56 poison kernel: usb 1-3: new device strings: Mfr=1, Product=2, SerialNumber=3
Dec 11 16:44:56 poison kernel: usb 1-3: Product: Qualcomm CDMA Technologies MSM
Dec 11 16:44:56 poison kernel: usb 1-3: Manufacturer: LG CDMA USB Modem
Dec 11 16:44:56 poison kernel: usb 1-3: SerialNumber: Serial Number

Dec 11 16:44:57 poison kernel: drivers/usb/class/cdc-acm.c: v0.25:USB Abstract Control Model driver for USB modems and ISDN adapters

Here we are interested in knowing the port on which modem is connected, which is ttyACM0

2) Copy and past the following lines into your /etc/wvdial.conf

[Dialer Defaults]
Modem = /dev/ttyACM0
Baud = 57600
Init1 = AT+CRM=1
Phone = 777
Username = internet
Password = internet
Stupid Mode = 1
Compuserve = 0
Idle Seconds = 30

3) Run the following command to update any missing parameter in /etc/wvdial.conf file

poison:/etc # wvdialconf update

4) Run the following command to start the internet connection

poison:/etc #wvdial
