Hi,

I haven't tried, but connecting the IT via ad-hoc wi-fi seems trivial, so that shouldn't be a problem. I've set up ICS before between an Ethernet and a 56kbps Modem and was quite easy to do, so I don't think that should be a problem, either.
Buuuuut, I've read somewhere in this forums that some people have managed/were trying to connect a usb modem directly to the N8x8, so you may want to do that instead.

Edit: I found this http://www.home-network-help.com/ad-...s-network.html and this http://www.home-network-help.com/int...n-sharing.html . After setting your computer in ad-hoc mode, you just have to connect to that network with your N8x8.

Edit2: If your laptop has bluetooth, you can probably set it up using the bluetooth modem.

Update: Just tried a ad-hoc connection. No problems at all.
