hmm you could try lowering the speed of the connection to see if you can stay connected. instead of 38666 try 28.8k or 33.6k

Will you post the listing for your file: /etc/wvdial.conf

sudo wvdialconf /etc/wvdial.conf

will allow you to edit it. Just cut and paste it in a posting.
If you have more than one wvdial.conf file, delete the extras, or specify
the file with:

wvdial /etc/wvdial.conf

You may need to set up the pap-secrets and/or chap-secrets file by running the following in a Terminal Window:

sudo pppconfig

You will need your userlogin, password, ISP provider information, and
pap or chap information for the connection. (You can set up pap and
then chap, if pap doesn't work.) Basically you just answer the questions
that are presented. You can delete a configurations and start over if
you need to from the menu selections.

For more information try this in a terminal window:

man pppd
man pppconfig

You should have a wvdial configuration file like this at
/etc/wvdial.conf (you may need to add a few things...)

wvdial.conf contains:

[Dialer Defaults]
Auto DNS = yes
Init1 = ATZ
Init2 = ATQ0 V1 E1 S0=0 &C1 &D2 +FCLASS=0
Modem Type = USB Modem
Baud = 48800
New PPPD = yes
Stupid mode = yes
;carrier check = no
Modem = /dev/ttyACM0
ISDN = 0
Phone = 4460568
Password = yourpassword
Username = yourusername@yourisp.net

Since you are dialing out, getting the carrier and then the connection is
dropped, most likely your ppp configuration is incorrect.

You can also try pon and poff to make a connection.

man pon
man poff

for more information
