internet connection sharing in vista over wireless ad hoc network

pwd

computer1: laptop with vista home premium 32bit
computer2:laptop with vista business 32 bit
vodafone mobile broadband modem connected to computer1.

There is a wireless network set up between the two computers with internet connection sharing set up. Computer1 is the host.
On computer2 there is a note saying there is limited conectivity on the wireless network and it cannot access the internet.
Does anyone know what the problem might be?

Thanks

(I typed this out earlier but it mustn't have posted properly or something)

On computer1 go to Network and Sharing Center - Manage Network Connections.
Select both your wireless adapter and the vodafone adapter.
Right click on either and select Bridge Connections.
You should then be good to go.

Thans for your reply - I tried what you suggested. Unfortunately it did not work.
It doesn't give an option to bridge conections with the vodafone connection. If you select them and choose bridge connections from the advanced menu it gives a message sayin that two connections must be selected which both are high speed internet or lan and have ics disabled (I tried disabling ics before doing this).
It lists the vodafone connection as a dialup connection. The vodafone modem is e220.

limited connectivity seems to be microsoftese for I can see a network but I don't have a usable IP address so you actually have no connectivity

use ipconfig at the command prompt or status on the network card properties to see if you are getting a 192.168.x.y address

I concur with Capt'n midnight that limited connectivity is usually an ip addressing issue.

Can you access files on computer 1 from computer 2?
