Step by Step guide for configuring an EVDO modem in Fedora 12

Step 1:

As of Fedora 12 the kernel modules needs to be inserted.
So open up a terminal and be the root user typing

su
password:


modprobe usbserial vendor=0x05c6 product=0x6000

Step 2:

wvdialconf /etc/wvdial.conf


You will get output like this:

Writing `/etc/wvdial.conf’.
Scanning your serial ports for a modem.

Found a modem on /dev/ttyUSB0.
/etc/wvdial.conf: Can’t open ‘/etc/wvdial.conf’ for reading: No such file or directory
/etc/wvdial.conf: …starting with blank configuration.
Modem configuration written to /etc/wvdial.conf.
ttyUSB0: Speed 460800; init “ATQ0 V1 E1 S0=0 &C1 &D2 +FCLASS=0


Step 3:

Now in the terminal type

vi /etc/wvdial.conf
Edit it now the wvdial.conf file should look like this.

[Dialer Defaults]
Init1 = ATZ
Init2 = ATQ0 V1 E1 S0=0 &C1 &D2 +FCLASS=0
Modem Type = Analog Modem
ISDN = 0
Phone = #777
Modem = /dev/ttyUSB0
Username = provided by BSNL
Password = provided by BSNL
Baud = 460800
Stupid Mode = 1

Step 4:
connect using the command
wvdial

It should look like this.




For disconnecting you need to close the terminal window or hit Ctrl+C

Now you are connected but you might not able to browse the Internet.
For this you might need to change the DNS server address manually.

So again hit the terminal.
vi /etc/resolv.conf

and add the following lines manually

nameserver 8.8.8.8
nameserver 8.8.4.4

These are Google DNS servers.

All done you can browse the Internet now.


Some thing different:
Now you can also connect the net from the GUI intself in Fedora 12.
Simly right click on the Network connections in the tray and select edit connections >> Mobile Broadband and add new connection and follow the steps to setup the connection.
Also put the DNS server addresses followed by comma.
i.e 8.8.8.8 & 8.8.4.4
It will be like this:
