I recently had to reload Fedora Core 5 (kernel 2.6.17.1.2174) on a Dell Dimension L900CXE and I cannot connect to the internet. I am using Linksys Wireless-G 2.4GHZ 54Mbps Broadband router and a Davicom DM9102/DM9102A ethernet card. My machine is linked directly to the router. The other pc (an XP machine) receives the wireless just fine. I allow computer to find the IP address.

When I boot up Linux, it tells me that it found the IP address, but when I get into Gnome, I can't access anything through any of my browsers. When I go to Network, if I disconnect and try to contact again and I get this error:


Determining IP information for eth0...PING 192.168.*.* (192.168.*.*) from 192.168.*.* eth0: 56(84) bytes of data.

ifconfig tells me this:

When I ping the IP, it appears fine:

but if I ping a named server, it doesn't work:

[root@localhost ~]# ping google.com
ping: unknown host google.com



When I start the DHCP client manually (using “dhclient”) I get this:

The computer recognizes my ethernet card:

[root@localhost ~]# dmesg | grep eth0
eth0: Davicom DM9102/DM9102A rev 49 at d8922c00, 00:80:AD:71:ABD, IRQ 11.
eth0: no IPv6 routers present
ADDRCONF(NETDEV_UP): eth0: link is not ready

I tested all the cables and they all work fine. I attempted connected the computer directly to the cable modem, but that gives me the same results. I've tried this with the firewalls and SELinux off and on. All the same results.

Any suggestions on how to get this working? I'm really stuck here. Any help would be greatly appreciated.

Thanks!

Rick

can you ping the router?
what does /etc/resolv.conf say?




psst...theres no need to * out internal ip addresses.

I logged onto the linux machine to get my resolv.conf:


search grandenetworks.net
nameserver 66.90.132.162
nameserver 66.90.130.10

These numbers are correct.

And to ping my router:

[root@localhost ~]# ping 192.168.*.*
connect: Network is unreachable

Um.. this is new.

So I decided to check some other things.


Somehow I've dropped my ip address:

[root@localhost ~]# ifconfig
eth0 Link encap:Ethernet HWaddr 00:80:AD:71:ABD
inet6 addr: fe80::280:adff:fe71:abdd/64 Scope:Link

collisions:0 txqueuelen:0
RX bytes:6303601 (6.0 MiB) TX bytes:6303601 (6.0 MiB)


and my IP routing table now looks like this:

.Kernel IP routing table
Destination Gateway Genmask Flags Metric Ref Use Iface
169.254.*.* * 255.255.0.0 U 0 0 0 lo

When I tried to add my router's IP address, I got:

[root@localhost ~]# route add default gw 192.168.*.* eth0
SIOCADDRT: Network is unreachable

I haven't changed any of my settings since I posted my original message!

What's going on?!?!?

Just last week, I was running FC5 on this same machine with this same router and configuration and it all ran just fine. (I had to reload FC5 for a variety of reasons. I did a complete drive swipe and loaded it frssh).

This is very frustrating. I've been using Linux for about three years and for the most part love it. This is is the biggest unsolvable problem I've encoutered yet.

Any help out there would be greatly appreciated!

you would have to add an ip address before you add the gateway, use system-config-network and set everything manually.

Tried it... and it still didn't work.

Any other suggestions?

So does anybody have any idea what I've done wrong or what I should try next?

If you read this it could solve your problem.

IT WORKS!!!

Thanks Arno for the post. While it didn't directly work, it sent me here. http://www.ubuntuforums.org/archive/...p/t-186430.htm

And that was the solution!!!

Thank you for everyone's help!

Your link had the solution in the first post and a nice instruction on how to.
The solution to blacklist tulip was also in the first link.

I seems to work for other network cards also.

sudo gedit /etc/modprobe.d/blacklist

After this is opened, you need to add "blacklist tulip", without the quotations, somewhere in the file.

Check with
lsmod
if dmfe module is loaded if not then , you need to add dmfe to /etc/modules.
To do this you need to open up modules with gedit by typing the following code into a terminal.

sudo gedit /etc/modules

Then, you need to add "dmfe" to this, without the quotes.

restart networking or your system

when i type this command:
sudo gedit /etc/modules

then gedit creat a new file and i add dmfe to this file and save, then lsmod but i cannot see the dmfe module.
I do as you said but my card still can not work.
I use USB Ethernet card dm9601 of Davicom.
lsmod
