Networking problems. Please assist.

[techsup1983]

hello I have just installed fedora core 3.
I am having terrible networking issues. I have set my netgear dg834g to function as a dhcp server.

In the network configuration section in fedora my network card 3com megahurst 10/100 card bus shows up. Status active, device eth0.

when I click activate using the setting 'automatically obtain ip address setting with dhcp, and unticked automatically obtain dns information from my provider
I get the error
determining IP information for eth0.....failed


If I use the other configuration static ip addresses. I click ok, activate and the box just simply disappears.
I cannot ping 192.168.0.1 or nothing.

I have rebooted but to no avail.
Tried another network cable.
Double checked router settings (all in order)
There is a light on the 3com card and on the router to show the cable is connected properly. I'm stuck.
Any help appriciated. Please assist. Thanks.

wouldn't you want the dns servers to be trickled down to your PC?
Is this a regular network card or Wireless?
when you did the install, did it or did it not detect your card?
quoting Fedora " it should just Work "
How many IP address have you alloted for your router?

Thanks for replying.
my netgear router acts as the dhcp server, I didn't mean dns sorry.
The network card is a regular 3com network card.
When I installed fedora it detected the card straight away.
My router can support upto 254 pc's.
I know it should just work, but i'm totally lost on why it wont work static/dynamic.

So you have a public IP addess from your ISP of for examle 44.44.44.44
your router has that IPaddress on the outside of it.
internally your router has a IP address 192.168.0.100
so and PC that you connect shoud start with 192.168.0.101 - whatever

In your routers configuration for dhcp you have a range of ip addresses it can hand out ? There should be no diffrerence whether the PC is windows or linux or mac etc...

That's exactly how it all works.

I'm having the exact same issue here. Started today.

post your ifcfg-eth0, and double check to see if your Netmask is set 255.255.255.0 and the gateway is set to 192.168.0.1

[Zigzagcom]

Many modem/routers use the 192.168.1.0 subnet, so if you are not sure what subnet the router works on, set your NIC initially to get its IP via DHCP. Also, you should get the manual from the manufacturer of the gateway device and see what the default settings are. Once you have some connectivity, you can customize your settings.

Here's my ifcfg-eth0:

DEVICE=eth0
BOOTPROTO=on
HWADDR=00:11:09:8a:a1:2b
ONBOOT=yes
TYPE=Ethernet
NETMASK=255.255.255.0
IPADDR=192.168.0.2
USERCTL=no
PEERDNS=yes
GATEWAY=192.168.0.1
IPV6INIT=yes

Does anything in this tell you that my network card is working? I was thinking of buying a new card but won't if I don't have to.

This is driving me crazy.

OK that looks correct, Now check to make sure the card is active, then try to ping the card....
If you can ping the card, try to ping the router. One thing you can check is the the Network Connections, highlight the card and click on configure and run through the tabs to double check the settings.
