Help - Default Gateway [SOLVED].

Stupot · Wed 10/10/2007 20:01:34

I've been doing some research and I'm now pretty clued up on what a default gateway is, but I still can't seem to find the answer to the main question which is:

Why won't my computer go online via the wireless network?

We have wireless rigged up in our house and we have a USB adaptor which I plugged into my computer and followed all the in structions and entered the Network Key etc etc etc. My computer is ow well and truly on the Network. Signal is constantly Good and Excellent so no problems there.

But when I try to go online it is still having none of it.

I ran a connectivity test and it came up with someting about this 'Default Gateway', apparently my computer hasn't got one...

Does anyone know anything about what I'm talking about and could they tell me how to set a DG so that my computer can browse the net through the family pooter?

Any advice is good advice (within reason, I'm a sensitive chap).

thanks

We need more info about the infrastructure.
What you mean by "browse the net through the family pooter"?
Is your PC using a shared internet connection (family PC's)?
Or are you using a router?

The gateway is the device between the internet and your own computer, btw.
So it's usually either the modem or the router.

We are using a router.
My mum's computer (aka the family pooter) is the hub, if you will. And the router is connected to that machine. That computer can surf the web no worries. W also have a laptop (which I'm currently using) which is conected to the internet with no troubles through the ame wireless network.

So I can't understand whats stopping my computer from going on the internet.
It won't do anyting that involves going online... MSN, IE, even AGV is telling me its out of dat because it asnt been ale to go online to get its automatic updates. Its basically like the olden days when you uplugged the modem.

But as I sid before, it is talking to my mums computer fine, just wont lt it go online... its like its welcomed me into its house but wont let me use the toilet.

The wireless connection is between your laptop and the router, right?
But don't worry about that now, do a basic test first.

On the computer that can see the internet, open a dos prompt and type "ping google.com".
You should get 4 replies containing google.com's IP address. It is 72.14.207.99 right now for me.

On your computer, open a dos prompt and ping that IP address. If you do get replies, the only thing left to do is set up DNS servers. Look them up in the main computer's network connection properties.

Hey Khris,
I tried your advice, but on my computer it came up wih no replies just a message saying something lke "google.com ould no be reached".

It's like the main computer has accepted mine as it's son but is refusing to pay child support.

Khris · Thu 11/10/2007 08:02:06

So the wireless connection IS between your laptop and the router, right?

Hmm, on your computer, did you ping google.com or the IP-address? It's important to distinguish between the two.

This sounds like good old fashioned out of date driver syndrome.

You're supposed to get the computer to talk to the router, not through another computer to talk to the router. That might be the problem.

Here is a lovely diagram I prepared to illustrate my dilemma.

Although I think Huw, you might have a good point.

At the dos promt, type "ipconfig".
Ping the laptops IP address, the router's (=gateway) LAN IP address.

Well I couldn't seem to get any joy from the DOS prompt advice you gave me. But closer inspection of the manual lead me to realise I was meant to have run the Router's CD after running the Adapter's CD in my computer aswell. The 2nd CD installed the BT browser and other bits and bobs, so I assume it was configuring the IP/gateway malarky as it was going.

So what it all boils down to is the fact that I am online and can officially start getting a groove on with my WIP and a few other little ideas I've had over the past few months.

Thanks everyone for the suggestions and advice. This thread is now officialy SOLVED (although I still don't get all this 'default gateway' rigmarole).

Basically in this concept, if you have several computers(devices/nodes) in a home network, and one of the nodes has a connection to another network (eg: Internet), you need to specify this node's IP address for every other computer on your home network so that they can use that node as a gateway to communicate with Internet.
