Wireless ad-hoc network with internet connection sharing

[Guest Veerle]

Hi,

 

I have a computer A with internet connection (ADSL connection through

USB modem) and computer B with no internet connection. Both computers

have Win XP. First I have changed the settings of my internet

connection so that it is shared. Then I connected computer A to the

internet using the (shared) internet connection. Then I have set up a

wireless ad hoc network on computer A as described in

http://www.microsoft.com/windowsxp/using/networking/setup/adhoc.mspx

Next I connected computer A to the wireless network (is not mentioned

in the article but I don't get it to work if I don't). Next I looked

at the available wirless networks on computer B and found the network

I created. So I connected to it. But computer B for some reason cannot

access the internet. So the internet connection sharing thing doesn't

seem to work. What I can I have possibly done wrong? What steps can I

take to find the source (and solution) of my problem?

On your computer A make sure that the wireless is assigned the IP address of

192.168.0.1 and let us know if that makes a difference. It has been ages

since I've played with it though.

Can you Ping Computer A from Computer B?

What the ipconfig /all output shows?

Does machine A Connected Wired to the Router/Modem or wireless?

Does Machine A has Two NICs one of them Wireless and you turned Broadcasting

ON . also do you use an Encryption method and you entered the SSID/Key on the

second Machine (B).

If the above Yes then you have your Firewall blocking the Network so try to

assign the Network to be allowed.

Chuck out the modem & buy a wireless ADSL router.

You need to connect computer B to a router either with a cable or

wirelessly.

That's the only way you will get computer B on the Internet.

You will need LAN connections on both PCs, all modern PCs have a LAN

connection, but you can always get a network card if there's no LAN

connection.

Re: Wireless ad-hoc network with internet connection sharing

 

Ok, some extra info:

 

Computer A makes a wired connection to the internet through a ADSL usb

modem. This internet connection works fine on computer A, I can do

internet stuff there. It is in the properties of this internet

connection that I turned on the internet connection sharing flags.

 

An ipconfig /all on computer A gives the following output in Dutch

(Windows XP is Dutch version). Basicly it says that there's no LAN

connection. Next comes the wireless connection through the ad-hoc

network. The Speedtouch connection is my internet connection using the

ADSL usb modem.

What concerns the wireless ad-hoc network, I used WEP with an

automatic generated key. I had to provide this key on both computers

when connecting to the wireless network. When looking at the available

wireless networks on both computers it says that I am connected to the

wireless network on both computers. It didn't say so until both

computers were connected to the wireless network.

 

When I ping computer A from computer B by "ping 169.254.132.197" I get

normal replies. So there must be some sort of connection between both

of them. It's just that the internet connection sharing doesn't seem

to be working.

 

When I ping computer B from computer A by "ping 169.254.74.92" I get

timeouts. I expected this would work as well, but appearently it

doesn't.

 

To Galen: it's clear that computer A doesn't have an ip address that

is 192.168.0.1. Is this absolutely necessary and if so, how do I

change this?

 

To Nass: I answered most of your questions above. Only I don't know

what NICs are and how to check of Broadcasting is on, so I cannot

answer that question. I did try to turn of zonealarm (my firewall) and

the Windows Firewall on both the internet connection and the ad-hoc

connection of computer A and i turned of the Windows FireWall on the

ad-hoc connection of computer B, and it still didn't work, so I don't

think that the firewall is the problem.

 

To Mike: I know it would be easier to buy a router, but according to

the Windows documentation, this should work. So I would like to get it

to work.

Re: Wireless ad-hoc network with internet connection sharing

 

I found the problem. The ad-hoc network is fine. But in the internet

connection sharing properties I selected that the connection had te be

shared, but appearently Windows XP selected the LAN network for this

sharing instead of the wireless network. It was readonly so I couldn't

change it there, but I ran the network wizard to correct this problem.

 

Than it worked when I disabled all firewalls (ZoneAlarm and the

Windows Firewall) for the internet connection. I turned the switch for

the Windows Firewall back on and made an exception for the wireless

network. Now it works.

 

Thanks a lot for everyone who helped thinking along!
