I have a Dell Inspiron B120 laptop computer with the Broadcom 440x 10/100 Integrated Controller for the Ethernet card.  The modem is an Actiontec GT701-WG.

Everything works fine in Windows XP.  In fact, I am using this laptop in Windows XP to enter this message.  So the problem is NOT a hardware issue.

However, in Damn Small Linux 3.3, the Ethernet connection does not work at all - neither the light on the Ethernet port on the laptop nor the Ethernet light on the modem are lit.  When I go into netcardconfig, it shows that my Ethernet card is not recognized at all.

What do I need to do?  If you tell me what commands to type, I can give you the output.

Is the card pci? If so, is it listed under "lspci"?

Does this card use the b44 driver? If so, is it listed under "lsmod"? If it does use b44 and it is not listed, does "sudo modprobe b44" install the driver?

When I select Yes to run modconf, I get an error message

So why isn't the Broadcom network card properly identified in DSL even though it is properly identified in Windows XP?

Well, it's not obvious that "Broadcom 440x 10/100 Integrated Controller" = "Broadcom Corporation BCM5705M 10/100/1000Base T" and ndiswrapper is for wireless networking

Did you try to load the b44 driver? - i.e. "sudo modprobe b44"?

Posted by jhsu on Sep. 29 2008,19:02
dsl@box:~$ sudo modprobe b44

Hint: insmod errors can be caused by incorrect module parameters, including invalid IO or IRQ parameters.

So why can DSL embedded in Windows XP connect to the Internet through the Ethernet cable but stand-alone DSL does not?  Why am I seeing a different netcard under two different working setups?  How can I get standalone DSL to do the same thing DSL embedded in Windows XP does?  DSL embedded in Windows XP is awkward and clumsy, and it doesn't even allow me to use an external USB drive.

[5] Internal Broadcom BCM5705M Gigabit Ethernet NIC

The ethernet card in this d600 works perfectly with the kernel 'tg3' driver. No issues whatsoever.

Ethernet adapter

There is a lot of history here. Initially drivers existed only here. Later, broadcom started giving its own drivers (source), here.

From version 2.4.22-pre10, the official linux kernel tree has a driver for the bcm 440x card. I don't know where the source that was embedded in the kernel came from.

For some time I have been using the driver from broadcom (version 2.0.5), without any problems. Now I switched to the driver included in the kernel and is seems to be working good as well.

For the auto module loading to work, I created the file /etc/modutils/eth0 with the following contents:

# build-in ethernet card from Broadcom
alias eth0 b44

Update 17-10-2003: I just discovered that the on board ethernet auto detects a cross or straight etnernet configuration. The b44 module has some problems with that. I was using a straight etnernet cable to connect two computers and this driver failed some times. The only solution I found was to remove the module and reload it.

2.4.x kernels

When running 2.4.18 kernel, I didnít find any suitable driver, I downloaded the Broadcom driver bcm4400 from their website. Using kernel-headers-2.4.18-bf2.4 package, I recompiled only the driver. Nothing to report: it works properly!

When switching to 2.4.27 Debian kernel, itís possible to use the free driver b44 instead.

See /etc/modules for 2.4.x kernels

Update: The 2.4.23 and 2.6.0 kernels include a working driver for the built-in Broadcom card. It is the "b44" module. This driver works well and is included in all recent linux distributions.

If you have a 2.4.22 or older kernel (eg in Redhat 9, Mandrake 9.1) then you can either update to a more recent release (Fedora Core or Mandrake 9.2) or compile the Broadcom driver yourself.

If you want to compile the Broadcom drivers as follows. Grab the linux driver from broadcom.com.

Don't recall what kernel dsl 3.3 has, but it could be a kernel issue.

That's because DSL embedded is seeing the virtualizer's (Quem, VirtualBox, VMWare, Parallel) virtual network card, not the physical device's (Ie, your laptops) network card.

DSL 3.x has kernel 2.4.26.  I seem to recall various problems with the b44 module, but it does seem he has a 57xx card.  Taking a look in mydsl: < http://distro.ibiblio.org/pub....00.info >

That may work for him, but from his first post description, and the hardware section of system stats reporting a device with pair "14e4:170c", it seems that it is indeed the 440x card that the dell b120 comes with. Thats the weird part, since lspci reports the 57xx card.
