Forums: 

Hi !
I have the BIGGEST problem in the world (for sure because it's mine :p)

I can't connect to the internet under Ubuntu 8.10 and wvdial;
after that wvdial enter the phone number, it tell me that he has lost carrier. this is my wvdial.conf file:

[Dialer Defaults]
Init1 = ATZ
Init2 = ATQ0 V1 E1 S0=0 &C1 &D2 +FCLASS=0
Modem Type = USB Modem
ISDN = 0
New PPPD = yes
Phone = 195
Modem = /dev/ttyACM0
Username = MYUSERNAME
Password = MYPASSWORD
Baud = 460800

and this is what I have in the console

root@hadi-laptop:~# wvdialconf
