UPDATE - Captivate USB tether

Ok, so the whole issue must have been the user and adding that user to the dip and dialout groups.

Once that was done, the network-manager-gnome setup worked flawlessly.

Sweet!

Captivate USB tether

Thank you AT&T. After the 'update' to 2.1-update1 the usb tethering no longer worked automagically. In fact, the whole option disappeared.

I kind of liked the option of tethering, even though I have an Aircard 860 wireless laptop connect card. When FIOS went down after a lightning strike, the tethering really came in handy. Also, my netbook doesn't support pcmcia, so the card is useless for that box.

The odd thing is, when I plug it in, with usb debugging ON, network-manager-gnome starts, and tries to setup up a new wireless broadband connection. The connection finds the phone, sets it up for At&t, but doesn't connect.

So, plan B:

1) Add your user to the dip group (sudo adduser user dip)*user is your user name*

2) Add your user to the dialout group (sudo adduser user dialout) *user is your user name*

3) Make this /etc/wvdial.conf file:

[Dialer Defaults]

Phone = captivate

Init2 = AT S7=45 S0=0 L1 V1 X4 &c1 E1 Q0

Modem Type = USB Modem

Init1 = ATZ

Modem = /dev/ttyACM0

Baud = 460800

Init3 = AT+CGDCONT=1, "IP", "WAP.CINGULAR"

ISDN = 0

Stupid Mode = 1

New PPPD = yes

Phone = *99#

Password = test

Username = test

Now all you need to do is:

4) wvdial

5) sudo ifconfig ppp0 up

You are now tethered.
