Hi,

You may wish to try on Ubuntu 7.04. You should be able to get it to work by using most of the references found on the web. I've managed to get it working with the following steps;

1. Start Ubuntu 7.04 with the USB modem plug in (you should see /dev/ttyUSB0, /dev/ttyUSB1, and /dev/ttyUSB2)

2. Edit wvdial.conf with the following settings (with reference to Singapore StarHub)

[Dialer hsdpa]
Phone = *99#
Username = star
Password = hub
Stupid Mode = 1
Dial Command = ATDT
Modem = /dev/ttyUSB0
Baud = 460800
Init2 = ATZ
Init3 = ATE0V1&D2&C1S0=0+IFC=2,2
ISDN = 0
Modem Type = Analog Modem
Init5 =AT+CGDCONT=1,"IP","shwap";

3. route add default gw 10.64.64.64

I've tried to get it to work on FC8, FC7, FC6, Ubuntu 7.10, and RHEL5 but to no avail.

Cheers,
Bernard Chew
