Dell Optiplex and bcm5751. So far no network

Wed · 04-02-2011, 08:01 AM

My Dell Model DHP (Optiplex) Small Form Factor. It is equipped with a Broadcom bcm5751 NIC.

During boot, it asks for 192.168.0.198 from the gateway, and it is acknowledged. However DHCP says it times out.

I can't ping the gate or the internet though. So I searched this forum and read this thread: http://www.linuxquestions.org/questi...33-3-a-526512/

tg3 exists in the vanilla Slack 13.1 system. Broadcoms supportpage mentions bnx2. But tg3 is in the download section of Broadcoms drivers.

Any help is appreciated

Are you sure you have the correct kernel module?

Issue "lspci -n" and put the output here to check your driver, then report back the findings.

Booted the machine with Knoppix and ran lspci -n

Code:

PCI ID	Works?	Vendor	Device	Driver	Kernel
14e41677	Yes	Broadcom Corporation	NetXtreme BCM5751 Gigabit Ethernet PCI Express	tg3	v2.6.25-

Suggestions?

I've got a Dell Optiplex 780 equipped with a Broadcom NetXtreme BCM5722 Gigabit Ethernet PCI Express (I think it's the same series). Works just fine out-of-the-box with Slackware 13.1 64-bit -- but with fixed-IP on the box.

Just for grins, have you tried running netconfig, choosing fixed-IP, give your box a name and domain, a fixed-IP address (like 192.168.1.10 or 192.168.0.10), gateway address (like 192.168.1.1 or 192.168.0.1, depending on your router), a mask of 255.255.255.0 and a "real" DNS server address (provided by your ISP or a public DNS server near you)? If you do choose to give this a try, it's probably quicker and easier to simply reboot the box to restart everything (and if you go back to DHCP, just reboot the thing and get back in business).

If you don't have lshw, you can get it from SlackBuilds.org; handy tool.

lshw shows

Code:

Hope this helps some.

lshw is not a part of Knoppix. If it is in Slack, I won't be able to post any result. If it isn't, it's a bit tricky getting it ...

But I'll give static address a try.

Edit:
No, it didn't work with static addressing either.

This Optiplex is a GX280. I am back in Knoppix to post this.

lspci is all I know how to muster to some level of relevance:

So, basically, it should work. In fact it does, at least in OpenBSD and Knoppix. But what should I adjust to get it going in Slackware?

Make sure tg3 is loaded, and no other module.

Issue "lspci -k" to see which kernel module is loaded for it.
