using ad hoc networks

Can anyone help with this? I have already tried many things...

I have no hotspot, but would like to use ad hoc.
How to configure?

CONFIG
1
telco-> ADSL modem-> hub-> 4 wires, one of them-> pc A
pc A has LAN card and a wireless card.
2
laptop has belkin card.

When installed they see each other (signal messages network
detected) but I cant enter. Message says no TCP connection.

How to do that without ICS, thats the question.

I have manually entered IP addresses.
ADSL modem has 10.0.0.138 so I am bound to that.
pc A has 10.0.0.20 for the LAN and 10.0.0.30 for wireless.
There a (sort of) bridge in between.

Laptop has 10.0.0.40

Everything else works fine, just not the ad hoc connection.
Microsoft wants you to use ICS that uses 196.... but then
everything is in disorder.

I tried 192.168.1.1 on the pc A (with 192.168.1.2) on the
laptop but then pc A looses the LAN connection. (problaby a
DHLC server somewhere takes over).


Hope this makes sense to someone, i am lost

thanks for your much appreciated help

Hans,

To connect more than one computer to DSL you need a router. It could be a
router device, or it could be a computer in the role of a router. The
easiest way to make a Windows computer act as a router is with ICS, but
that's not the only way. With NT, W2K, or XP you can enable routing between
two adapters without using ICS.

A router connects networks. There are two networks in your case: the link
between the DSL modem and PC A (which has two adapters) is one network; the
wireless LAN is the other network.

You have no need of a hub between the DSL modem and PC A. There is no
possibility of connecting another computer on this link, so just get rid of
it.

Different networks must have different network addresses. Every host
(computer or router) in a network must have a host address that belongs to
that network. You have assigned both adapters on PC A addresses belonging
to the same network, even though they will be connected to different
physical networks. You must change that. You can't control the addresses
that are used on the DSL modem link; they are controlled by the DSL
provider. For your LAN, you should use one of the address ranges that are
reserved for private networks: 192.168.0.x, 192.168.1.x, etc. There are
others, but these will do. So all the wireless adapters in your ad-hoc
network (including the wireless adapter on PC A) must have addresses in the
192.168.0.x (for example) range. If you use ICS, these addresses will be
configured automatically.

Hi Ron, thank you for your answer.
Sorry I forgot to mention that my ADSL modem contains a
router and a firewall.

Let me refraze:
ADSL modem/router/firewall has 10.0.0.138
Pc A has 10.0.0.20 for the LAN and 192.168.0.1 for wireless.
Pc B has 10.0.0.21 and so on
Laptop has 10.0.0.25 on the ETH card and 192.168.0.2 for Belkin.
The LAN wire is remove from the laptop, to get the wireless
working.

There is a spanning bridge in Pc A connected to the wireless
adapter.

ICS not used. The two 2.5 GHz adapters see each other, but
no connection. Problaby no TCP.

I also tried 192.168.1.1

thanks for your much appreciated help

PC A is connected to two networks: 10.0.0.0/255.255.255.0 and
192.168.0.0/255.255.255.0 . Different networks cannot be connected by a
bridge; they must be connected by a router. ICS can be your router. I
would get rid of the bridge and install ICS.

I hope that answers your question. If not, we'll keep at it.

Hi Ron,
I was already afraid that this would be the answer.

If I choose ICS I can't see the modem /router anymore, I
already did that.

So it means I have to change 10.0.0.138 into 192...
I suspect it is a factory setting that cant be changed.

So testing with 192 and forth, there is no guarantee that I
can set it back to its original settings (which I have
tweaked anyway). Sounds like a lot of work too.

Thank you for your help, you confirmed what I suspected,
that it cant be done.
-----------------------------
Assume I leave the LAN at 10... and the wireless at 192, no
internet, oke.

But why is there no printer and file sharing ?
Settings are on.

regards
hans

Hans,

It is not sufficient, or even possible, to make the two networks use the
same network address. Different networks must use different network
addresses. The link to the ISP is one network, and your LAN is another
network. You must have a router between them. That could be a router
device or ICS. I recommend a router device. With a separate router, you
won't have to boot an ICS computer just because you want to connect to the
Internet from some other computer. Home routers are low power and quiet.
New ones also provide decent firewall capability. And they're cheap
(~US$80).
