Finally, I can use my beloved HSDPA modem on ubuntu 9.10. I’ve tried using Network Manager, but not working. So, after googling, I found We can using wvdial as alternative. Sierra doesn’t support its product for Ubuntu 9.10. So this can be an alternative.
First, of course, we have to install wvdial. This installation is very easy. We can using Synaptic Package Manager.
Second,we need to know where is the location of modem detected by Ubuntu
Third, we need to modify /etc/wvdial.conf We can modify using command:
sudo gedit /etc/wvdial.conf
Below is the sample of my configuration:
Dialer Defaults]
Init1 = ATZ
Init2 = ATQ0 V1 E1 S0=0 &C1 &D2 +FCLASS=0
Init3 = AT+CGDCONT=1,”IP”,”Indosat3G”
ISDN = 0
Modem Type = Analog Modem
New PPPD = yes
Phone = *99#
Modem = /dev/ttyUSB0
Username = indosat
Dial Command = ATDT
Password = indosat
Baud = 9600
Connection = internet
Auto Reconnect = off
Abort on Busy = off
Carrier Check = on
Check Def Route = on
Abort on No Dialtone = on
Stupid Mode = on
Idle Seconds = 0
Auto DNS = on
Dial Prefix =
Dial Attempts = 1
I’m using Indosat3G. Its APN is Indosat3G. And my modem detected by ubuntu on /dev/ttyUSB0. We must be careful in this stage, because every operator has a different setting on APN and username/password.
And finally: Online!! To become online, connect your modem to USB port and write this command on terminal:
sudo wvdial
And wait several seconds, untill you have the status below on your terminal:
–> WvDial: Internet dialer version 1.60
–> Cannot get information for serial port.
–> Initializing modem.
–> Sending: ATZ
OK
–> Sending: ATQ0 V1 E1 S0=0 &C1 &D2 +FCLASS=0
OK
–> Sending: AT+CGDCONT=1,”IP”,”Indosat3G”
OK
–> Modem initialized.
–> Sending: ATDT*99#
–> Waiting for carrier.
CONNECT
–> Carrier detected. Starting PPP immediately.
–> Starting pppd at Fri Jan 22 10:02:01 2010
–> Pid of pppd: 4451
–> Using interface ppp0
–> local IP address 10.204.8.126
–> remote IP address 10.64.64.64
–> primary DNS address 124.195.15.98
–> secondary DNS address 124.195.15.100
You have to make sure that you get the IP Address and DNS Address. If not, your setting on /etc/wvdial.conf is not correct yet. Pls recheck APN, modem location and username/password.
Hopely helpfull.
