Hi,
can you help a complete network newbie.

Computer A, is attached by wired ethernet connection to Wireless ADSL router.
It can see the internet, my ISPs DNS and it can see Compuetr B.

Computer B, is attached to an ethernet hub, which in turn is attached to a wireless bridge.
Computer B can see computer A.
And it can bring up the web interface for both the bridge and the ADSL router.

However, compuyer B can't resolve domains for anything on the internet, nor can it find web sites if I type in the IP address.

I can only assume part of the setup on either my bridge, or router is wrong/missing but most of the terms mean little or nothing to me (especially in the 'routing' section)

Can anyone give me basic help or point me at some dummies guide/FAQ etc that I've as yet been unable to find.

ADSL router is a BT Voyager 2100
Bridge is a linksys WET54G

Many thanks for any help/advice and ligh abuse.

There are a couple of things that can cause the problem. First is whether Computer B has the correct IP address for default gateway. Second, is Computer A set up as a GW with nat translation or are you using the Wireless router for that? If you have a wireless router, why do you need a wireless gateway device? Doesn't the router serve that function?

Does the Router translate IP addresses to allow network sharing? If so, is the address of the router used as the default gateway device?

Make sure that the default gateway and nameserver settings are correct on Computer B. Since you can't reach remote websites using an IP address, it sounds like Computer B doesn't know where to send default traffic.

One other thing that I've seen is that using both wireless and wired ethernet can cause the wrong device being used to try to contact the DHCP server however since the computer with the problem has just a wireless interface, It doesn't look like that is the case here.

You will want to look at the ifconfig and iwconfig outputs t verify that they are what you expect.
The router may have a clients table. Are both computers on it?

Thanks folks,
With your help I've manaaged to solve this.
Looking for the answers to some of jschiwal's questions and a 'similar thread' that the site threw up, but my searches hadn't, led me to use the route command to add the ADSL modem as the default gateway on computer B.
I thought I had tried this with the gui for network connections, but it hadn't worked.

Have now added the default gateway to computer B and it has access to the internet.

Thanks again.
