Last week I bought a new laptop and now I've got a problem with my network. What is really weird is that sometimes (but very rarely) networks works just fne, but usually it doesn't work at all

My configuration is:
IP: 192.168.8.212/24
gateway: 192.168.8.251
DNS: 192.168.8.251
DNS: 194.116.252.2

ifconfig:

the interesting thing is your packets counts from ifconfig are all zero...Which means nothing is going out on the wire.

Is there anyting intersting in dmesg?

I've installed Gentoo 2006.0 once again and I still cannot connect to the Internet, but there is something more weird. When I run ifconfig I get:

Ok, you're right, but when I do something like this:

Everything works under WindowsXP, so I think that it isn't cable or switch problem.

can you update the dmesg to your new install?
an lsmod would also be nice!
/edit
sorry its getting late...

dmesg I put before was the one from my current system.
lsmod:

So how could I make it no to load the 8139cp module?

nativemad · Posted: Fri Mar 03, 2006 11:30 pm Post subject:

what about rmmod 8139cp ?

dmband · n00b Joined: 02 Mar 2006 Posts: 33 Location: Poland

Ok, I've done this, but what than? I suppose I should load 8139too module, but could you tell my how? Besides after rebooting the system this 8138cp module is still loaded.
And the last thing, after removing and adding these modules, how should I check if it is working? Will

I did as you had said, and I get:
ifconfig eth1 (after setting the IP address)

What does ping do? Does it give an error?

Also, what is the output of "route -n" ?

have u checked broadcasts and netmasks on the destination host? they should be the same everywhere in your network. what kind of machine is it? are there any firewall-settings anywhere that might block sth.?
and please, do check all cables.
check the output of

I think that everything is fine now.
I've added:

Can you paste the dmesg after you have done the "modprobe 8139too"? I am sure there is a resource conflict or something - especially if it is working under windows. The configuration you are doing looks fine.

It's me again

Everything was fine, but after reboot network connection doesn't work anymore

The 8139cp module seems to be loading again as well as the 8139too. I think we have concluded that the 8139too is the right module though.

Perhaps you could try recompiling your kernel and removing the support for the 8139cp module. (or you could just move it to a /tmp folder and run modules-update and reboot).

To be honest I don't know how to remove the module

But I edited the file /etc/modules.d/aliases and added line:

Ok, the interesting thing there is that now the 8139too is listed as being used. Which I presume then that after reboot ifconfig works?

Can you paste your dmesg one more time? I am running out of ideas but let me see if I can see something. It could be a apic issue.
