New Laptop - no networking

Onion · n00b Joined: 05 Jun 2003 Posts: 3

Just got my new laptop today, naturally, Gentoo was high on the list. So I began the boot from the live CD, but networking doesn't seem to run with DHCP. OK, set it manually via net-setup eth0. Still can't ping anything except the localhost. Maybe the net card is too new..... Tried booting with smp noapm pci=noacpi as I read somewhere in these forums, and have tried variations, all to no avail. At least when I use the smp kernel, I can see eth0 detected, however, when I use the gentoo kernel, I see 'No Network device auto detected....' The box does have a wireless onboard Lan, and is seen as lo. However, at the moment, I have no WAP for it to see. Any help much appreciated. Hope all of that makes sense...

Laptop - IBM G40 2388-5BM.
P4, 3.06 Ghz
15' display
512mb ram
40 gig HD

It'll be a REALLY nice laptop if I can get it working !!!!

first thing u should do is to find out which eth-card u have, then u can chose the right module to run the card -> 'modprobe <module>' - once u are sure that the card is running ('ifconfig') u can start to configure the network...

perhaps u should post the output of 'ifconfig' along with the data on your internet connection (ip, gateway,...) - we can help u better then...

The lo device is a loopback device, it should not be your wireless LAN card.

don't know if this helps..but it worked for me and my pcmcia nic

1) boot gentoo cd
2) enter the following

insmod pcmcia_core
insmod i82365
insmod ds
cardmgr -f

3) net-setup eth0 and select DHCP

This worked for me and made my non-detected NIC automatically come up after booting the CD and entering these parameters. i'm a newbie so i don't know if you already tried this. it's probably obvious to most people, but i had to search on google to figure this out as the gentoo install docs make no reference to laptops.

slartibartfasz,
The net card is a 'Broadcom Extreme Fast Ethernet' according to WinXP. On PCI Bus 2, IRQ 11. What module would I use with modprobe ?

paranode,
Thanks - noob alert !!!

mlh,
The net card isn't pcmcia, it's on the M/B.

Output from ifcong -

Not really a solution for others with the same problem, but....
I found an older DLink 650, and booted with smp noapm dopcmcia - and it worked out of the box....

Good enough for now.
Thanks for the replys.

Oh, and wilburpan,
None of the bcm* mods seemed to work...

Got to go now...... installing to do !!!

Thanks again.

I administer a lab at a university that has several of these Thinkpad G40 Laptops. I've found that the best way to get a system up and running is to use a 2.6 livecd that includes the orinoco_pci or prism2 modules and use the wireless connection to do everything through kernel and bootloader setup, then start using the onboard ethernet after your first reboot. Depending on your notebook's revision, you'll either use the tg3 (Broadcom Tigon3) module, or the bcm5700 (Broadcom 5700) module for ethernet under a 2.6 kernel. This applies for Thinkpad G40's that report the onboard ethernet as a "Broadcom Extreme Fast Ethernet" in Windows 2000 and XP.

This was the case, at least, in October of this year. I'm actually working on a new hd image for these laptops during the upcoming semester break, and I plan to use the latest livecd out at the time.
