help me to set up a home network with the router/modem

Hi,

I am trying to set up a home network in order to share broadband. I have one desktop running Windows Me and one laptop running Linux Fedora Core 3 and Windows XP (dual boot). I linked both computers to a ADSL modem/router with network cables.
I have a real problem with Linux now. I specified IP address, gateway address, etc. (settin this to "Automatically obtain from the provider" does not work at all).
I can activate my eth0 but I can't connect to the internet. I had a similar problem in Windows. I solved it by setting "Link Speed/Duplex Mode" to "10 Half Mode" for the ethernet device. Can anyone tell me how I can set this speed in Linux.

Can anyone help to configure my eth0? Earlier I connected only one Linux computer to the router and it was working fine with automatic settings. Now it does not work.

Cheers,
Irena

If you need to set it to half duplex then you can use ethtool or mii-tool. I would also check that your dns settings are correct in /etc/resolv.conf

Is the modem/router set to be a DHCP server? When I had this problem, nothing was providing the IP addresses the computers need so they can connect. Turning it on in the router fixed it. The computers need to be set to receive the IP addresses, etc., automatically.

One other possibliity--hopefully remote--is that two devices are trying to assign IP addresses. If that were to be the case, strange things could happen.

Let us know how this comes out.

Thanks for your replies.

The DHCP option in the modem/router configuration is set to on. I am using pppoA connection. For some reason the router does give a correct IP address to my laptop running Linux/Win XP, therefore I had to set it manually. Perhaps it is something to do with the pppoA connection?

Sorry, I meant to write "For some reason the router DOES NOT give a correct IP address to my laptop running Linux/Win XP, therefore I had to set it manually".

I set IP address, gateway, etc. to "obtain automatically" but left "Link Speed/Duplex Mode" = "10 Half Mode" in Windows XP. In Linux I just set everything back to "obtain automatically", restarted my computer and it works in both Linux and Windows (hopefully I will not get any more problems when I power my laptop on tomorrow).
Miracles do happen!
