Internet Connection Sharing problem

[Theslaz]

I'm trying to set up a AD-HOC connection between 2 laptops. Have a
connection; just can't get them to share the internet. When I go into
the Wireless Network Connection properties and attempt to check the box
to allow other network users to connect to the internet I get this error
"ICS can not be enabled due to an IP address conflict on the network" It
appears that the address "192.168.0.1" is already in use.

How can I check what/who is using this address? My desktop computer is
connected to a wireless router that is using that address. If this is
the problem; is it possible to change that address so that it becomes
available for my AD-HOC connection.

Thought I'd ask before I start testing!

If you have a wireless router, why are you trying to set up an ad hoc
connection? You don't want to use ICS when you have a router. And yes, of
course the router is 192.168.0.1 and that's why you can't assign that IP
address to a computer.

Please explain.

Holidays! RVing. Most campgrounds have WiFi; but it is usually a weak
signal or out of range. I have an antenna booster on one of the laptops
that usually gets me a decent signal and I want the second laptop to be
able to share the connection. Now I know that I won't have the router
with me and therefore I probably won't have a conflict with 192.168.0.1;
however; I would like to have it set up working at home; therefore; I
will know that it will be working on the road.

I have done some research on routers and it appears that one can change
the IP address. Just want to make sure and would like to know if it
means that I will have to reconfigure my router /home computer. If its
to much work; I won't bother.

You certainly can change your router's IP address to a different subnet (ex.
192.168.1.1), but if you've set your laptops to have static IPs for the ad
hoc network (192.168.0.x), they won't be able to get the Internet at home.
Here is a link for setting up an ad hoc network from MVP Barb Bowman:

Maybe something there will help you.

Maybe you'd be better off using a wireless service (and wireless network
adapter cards) from someone like Verizon instead of trying to do ad hoc. Of
course it depends on where you live and what's available. I have clients
who manage their wireless connections that way when they go camping on the
beach. Just a suggestion since I don't know anything more about ad hoc
wireless networking.
