Ericsson f3507g WWAN (3G Broadband) and AT commands

I have a lenovo x200t tablet with WWAN built into it.

I'm trying to connect to the internet using AT commands and a C# program which I am making so that the program can connect to the net and upload information on demand.

I don't want to use Lenovo's "Access Connections" as it is too complicated for the end user.

So far I have been able to use terminal to turn the card on and off, ring landlines and send SMS messages. However I can't seem to access the internet using it.

I could access the net through it before I removed "Access Connections" software/bloatware.

The commands I am using to try and access the net are:

1. Connect on COM7 to the modem
2. Send initialisation string "AT+CFUN=1"
3. Send AT*ENAP=1,1 as suggested here (http://www.thinkwiki.org/wiki/Ericsson_F3507g_Mobile_Broadband_Module)

Windows says it is "Identifying" the network and a yellow exclamation mark appears on the networking icon in the task bar, but the connection fails and drops off.

An IP is assigned to the "Local Area Co开发者_StackOverflow中文版nnection 2" of 169.254.1.192 with a subnet of 255.255.0.0 - no gateway or DNS.

Definately no net connection...

Anyone got any ideas?

I got in contact with Vodafone in Australia and

1. their towers were not compatible with my modem. This has subsequently been fixed.
2. I needed a public IP from them (at no cost)

Problem solved..
