[SOLVED] Huwaei 1260 USB broadband Modem configuration in Centos5.4
 

Dear readers,
This is a post just in case anyone has difficulty in configuring the USB modem Huwaei 1260. My service provider is Tataindicom from in India.
I'm using photon plus broadband connection. Here's how I configured it.

Login as root.
Insert the modem in a USB port.
Do a lsusb command.
You will get the vendor id and the product id.
[root@localhost ~]# lsusb
Bus 003 Device 001: ID 0000:0000
Bus 002 Device 001: ID 0000:0000
Bus 001 Device 001: ID 0000:0000
Bus 005 Device 002: ID 15d9:0a37 Unknown Mouse
Bus 005 Device 001: ID 0000:0000
Bus 004 Device 002: ID 12d1:140b Huawei Technologies Co., Ltd.
Bus 004 Device 001: ID 0000:0000

Here the vendor id is 12d1 and the product id is 140b.
Now you have to do a modprobe.

[root@localhost ~]# modprobe -r usb-storage usbserial
[root@localhost ~]# modprobe usbserial vendor=0x12d1 product=0x140b

Run wvdialconf as below.

[root@localhost ~]# wvdialconf /etc/wvdial.conf

Found a modem on /dev/ttyUSB0.
Modem configuration written to /etc/wvdial.conf.
ttyUSB0<Info>: Speed 460800; init "ATQ0 V1 E1 S0=0 &C1 &D2 +FCLASS=0"
ttyUSB2<Info>: Speed 460800; init "ATQ0 V1 E1 S0=0 &C1 &D2 +FCLASS=0"

The modem configuration will be written in /etc/wvdial.conf as below.

[root@localhost ~]# cat /etc/wvdial.conf

[Dialer Defaults]
Modem = /dev/ttyUSB0
Baud = 460800
Init1 = ATZ
Init2 = ATQ0 V1 E1 S0=0 &C1 &D2 +FCLASS=0
ISDN = 0
Modem Type = Analog Modem
; Phone = <Target Phone Number>
; Username = <Your Login Name>
; Password = <Your Password>

Make changes as below to the /etc/wvdial.conf

[Dialer Defaults]
Modem = /dev/ttyUSB0
Init1 = ATZ
Init2 = ATQ0 V1 E1 S0=0 &C1 &D2 +FCLASS=0
Stupid Mode = 1
Modem Type = Analog Modem
Phone = #777
ISDN = 0
Username = internet
Dial Command = ATDT
Password = internet
Baud = 9600

Run wvdial

[root@localhost ~]# wvdial

Wow You are on to the net.

If your browser gives problems loading the pages add the nameservers in /etc/resolv.conf as below.

[root@localhost ~]# cat /etc/resolv.conf
search localdomain
nameserver 203.200.230.244
nameserver 202.54.29.5

Then run the browser, there should not be any problems.

Are you not suppose to block USB storage device so kernel can recognize it automatically?

Here is package I used to provide Huawei USB modem from CentOS 5.1. I do not know if this is still needed:

Here is also interesting application for Huawei USB Modems.

Oh, yes. please correct title of this thread, you misspelled "Huawei".
