still no internet - please help

[limejuice]

Hi there, my eth0 device will not activate. I've read all the relevant posts I could find here - I've turned off the kudzu service, I've made sure the network service in runlevel 5 is started before PCMIA or ACPI and I've also changed my modprobe.conf to read de2104x instead of tulip as another person suggested, all to no avail. I know it's something in FC2, as my internet was detected and worked perfectly in FC1. I have a cable modem and use DHCP.

In the service manager, I noticed that two devices are present - "lo" (loopback device) and "eth0". Only "lo" is activated though and like I said, FC2 will not activate the eth0 device, and it fails to start during the bootup process.

I am a Linux novice and this is becoming very frustrating, so any help would be appreciated.

Thanks!

What is the output of ifconfig -a? Also, what happens when you enter ifup eth0?

[limejuice]

Here is the output of /sbin/ifconfig -a:

Here is the output of /sbin/ifup eth0:

tulip device eth0 does not seem to be present, delaying initialization.

what card is it? you may need to recompile your kernel to include the proper driver, and edit /etc/modpobe.conf to link the driver to the card.
example:
alias eth0 driver_module_name

[limejuice]

It's an Intel 21041-based PCI Ethernet Adapter (make is RCA). That's all that Windows System Information tells me. I also have a 1394 card, so I thought there might be an IRQ conflict or something, but FC2 recogized it fine according to the Hardware Browser.

Could you please post the output of /sbin/lspci ?

like:
change the line from:
alias eth0 tulip
to
alias eth0 tulip_old

[bradthemad]

What happens when you do a `modprobe de2104x` or `modprobe de4x5`?

[limejuice]

Adding tulip_old to modprobe.conf didn't work.

When I did modprobe de4x5 nothing happened; I was just given another command prompt.

When I did modprobe de2104x, a message came up saying "localhost kernel: Disabling IRQ #5" and it froze there - I had to reboot as everything froze up, including my mouse.

Guess I'll have to wait until the next version of FC, or else downgrade to FC1.

[Jackflash]

I too have the same issues - although my work around is to boot in Win XP, which detects the NIC - shut down XP and boot into FC2, which now detects the NIC....

I **think** that FC2 cannot resolve dynamic IP.... I am too much of a noob to resolve this....

strange eh?:confused:

[limejuice]

Yeah, it's really strange. I think it comes down to the complications of moving to the 2.6 kernel. My NIC works perfectly in XP (which I dualboot), and it worked perfectly in FC1, so I know it's something to do with FC2. I did try upgrading my kernel in FC2 to the latest, and using modprobe, I was able to get my hardware detection correct (i.e., it would activate my eth0 successfully upon bootup), however it would also say "Disabling IRQ #5" at the same time which rendered my mouse inoperable!! I set my static IP, gateway, DNS, etc., and it *still* would not access the internet. Every time I rebooted and logged in, after a short time the entire system would freeze, so I figured the kernel upgrade likely made a lot of things unstable (or else I just didn't do it right) and of course, I had no mouse anymore, so I've just reformatted and await the next distro which will work out all the kinks with the 2.6 kernel.

[superbnerd]

if you loaded the module with modprobe and nothing happened and you got another prompt then the module loaded correctly. now you have to activate the card. try the command "/sbin/ifup eth0". if you get an error, you need to go to /etc/sysconfig/network-scripts/ and look for a file called "ifcfg-eth0." if there is not one, you need to create with contents something like this:DEVICE=eth0
IPADDR=192.168.1.5
NETMASK=255.255.255.0
NETWORK=192.168.1.0
BROADCAST=192.168.1.255
ONBOOT=yes
NAME=Ethernet
USERCTL=yes
PEERDNS=yes
TYPE=Ethernet
IPV6INIT=yes
DOMAIN=
DHCP_HOSTNAME=192.168.1.1 #or whatever you DHCP server's address is
HWADDR=
BOOTPROTO=DHCP
GATEWAY=192.168.1.1 of course your ip addresses might be different.
then you should be able to use the command "system-cotrol-network" to configure it.
also make sure you put "alias eth0 driver_module_name" in /etc/modpobe.conf

hope that helps

I'm posting this from FC2, so I'm relieved to say my internet is working! Here's what I did:

1) Made an update CD as per the Unofficial FC2 Guide's instructions and updated FC2. I'm not really sure if this made a difference though.

2) I ran /sbin/modprobe de4x5 and then /sbin/ifup eth0 and I had internet access. After I did these things though, no program would launch! Everything I clicked would just hang and never run/open.

3) What clinched it was replacing "tulip" with "de4x5" in /etc/modprobe.conf. Upon reboot everything worked. I was for once happy to see the lovely Gnome error asking me to "Log in Anyways".

Thanks for all your help!

that is wonderfull. it means: card found and now in use.
