Hi,
I have a problem setting up Internet Connection Sharing on my Windows XP computers. My modem is connected to my laptop through ethernet. Laptop and PC are connected to the router through wireless adapters. Laptop is the gateway computer with 192.168.0.1 as IP.

Internet Gateway is displayed (and connected) on the PC. The problem is that the internet is not working on the PC, even though it is working on the laptop and the PC recognizes the Internet Gateway...
Did I miss anything obvios? Also my PC is receiving 1k/s from the Gateway all the time, is this normal behavior?

I would just like to add that there is no problem file sharing or playing games through the wireless network.

Ahh, I might also add that to connect to internet I use pppoe (I have to enter username and password).

If you are using a router you dont need Internet Connection Sharing, the router does that.

The connection should be Modem > Router > Computers.

The Laptop get the Internet becasue it has the modem conneced to it. All computers should get the Internet through the router.

Actually should be:

Modem
Laptop
ICS WiFi Ad Hoc Mode

Wifi on PC in Ad-hoc mode

You do not need a router with ICS.

check that the pcs firewall isn't preventing access to the internet.

On the laptop do a ipconfig at a cmd prompt.
What is your ip for the internet nic and for the wireless nic?

They can not be in the same subnet. In other words, if internet is 192.168.0.x the wireless can NOT be in the same subnet. It would need to be in a different subnet like 192.168.255.x

Imagine the power if you knew how to internet search

>> You do not need a router with ICS. <<

No. If you have a router you do not need ICS. ICS is an inferior solution to a problem that is best done in hardware via a router.

As the OP already has a router, he might as well use it the way it was designed to be used. It is a far easier and more reliable solution and alleviates all the hassle with different sub-nets.

To discard a router in favour of ICS is a silly thing to do.

StuartS the OP doesn't have a router. When the OP referred to a router s/he was referring to the ICS laptop.

wanderer we are reading different posts ??

"Laptop and PC are connected to the router through wireless adapters."

He says adaptors that means more than one !!!

And your point was???

My point to StuartS is he is reading the post like there is a real router, which he does not have, which is why he is using ICS

You write: "He says adaptors that means more than one !!!"

Of course. Means he is doing ad-hoc wireless between the laptop and pc like you pointed out in post #4.

So just to clarify I read the post as using ICS on the laptop to connect a pc wirelessly via ad-hoc wireless to the laptops wireless card. Laptops ethernet port is connected to the PPOE DSL connection. The laptop is the "router" by running ICS.

What I wonder about is this statement "Internet Gateway is displayed (and connected) on the PC."
What is "internet gateway"? Almost makes me think the poster also put ICS on the pc which would cause a problem.

>> What I wonder about is this statement "Internet Gateway is displayed (and connected) on the PC." <<

Thats what made me thing the OP is using a router and not a laptop acting as a router. Thats what happens when you start using a noun as an adjective without clarification. It causes confusion.

I think the OP needs to come back and explain exactly what they are doing.

Stuart

I read it as..............

Modem
Laptop
ICS WiFI to Router
PC receiving WiFi from router

WGAF anyway ?

If you log on with ppoe you won't get the correct range that ICS needs.

Disable ics. Return to working state.

Get analogx's proxy and read the readme file.

I read it wrong and answer it wrong too. So get off my case you goober.

Thanks for your responses.
Sorry for not explaining clearly in my first post. I made a drawing of my network:

The laptop is distributing the connection through Win XP ICS and the laptop acts as the gateway, while PC is the client. Actually the connection seems to work partially on PC, but I can only access some internet pages, while other do not load at all. For example this forum works, but Google does not work. Very strange. I have disabled Win XP firewall and ZoneAlarm and I suspect that the router might be blocking access to the internet, but I am not sure.

Anyway, you convinced me that the ICS solution is inferior, but how should I connect instead?
Should it be:

Modem
Router
2 computers

or

Router
2 computers

I am using BT Voyager 2500V router and when I was having internet conenction through British Telecom I only needed this router to connect. Please take a look at the screenshot of the router configuration:

Any advice how I should configure it? I should probably add a new conenction with my username/password, but if you have any other advice let me know.

BTW, BT Voyager 2500V router firmware usually does not allow to access internet through other ISP's, but I successfully upgraded to a firmware which will allow such configuration.

If you have a BT Voyager 2500V use it and stop messing about with ICS. The 2500V is a good router with built in modem, wireless and VoIP capabilities.

Just plug the telephone cable into the ADSL socket on the 2500V and and your computer into one of the Ethernet sockets, configure it and you are set up. You can then connect the other by wireless if needed. You can discard the modem you already have.

No software needs to be installed on any computers except standard network software that comes with Windows. If you want to use the USB connection that is incorporated into the 2500V you may need to install the necessary USB drivers.

"Just plug the telephone cable into the ADSL socket on the 2500V and and your computer into one of the Ethernet sockets"

Do I have to connect through Ethernet? I would prefer wireless. I assume that conenction through Ethernet is not mandatory, but correct me if I am wrong.

I listened to your advice and configured the router, but some of the settings might not be correct, because the connection fails to establish. I have just contacted my ISP support through e-mail requesting to provide me with correct settings. I will let you guys know about the progress later.

>> Do I have to connect through Ethernet? I would prefer wireless. I assume that connection through Ethernet is not mandatory, but correct me if I am wrong. <<

You need at least one computer connected through Ethernet, initially at least, in order to configure the wireless and other settings. You cannot do that through wireless unless you know what all the default settings are which often do not include any security settings.

You need your user name and password provided by your ISP to configure. There is a place in the router configuration screen for that. All other settings should be automatic to allow you to connect at least but there are some you need to tweak, especially wireless security.

The manual that came with the 2500V is a good place to start.
