Networking :: Ethernet connection not working in DSL on laptop



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
/usr/sbin/modconf: line 178: /usr/share/modconf/params: No such file or directory.

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"?
dsl@box:~$ sudo modprobe b44
/lib/modules/2.4.26/kernel/drivers/net/b44.o: init_module: No such device
Hint: insmod errors can be caused by incorrect module parameters, including invalid IO or IRQ parameters.
     You may find more information in syslog or the output from dmesg
/lib/modules/2.4.26/kernel/drivers/net/b44.o: insmod /lib/modules/2.4.26/kernel/drivers/net/b44.o failed
/lib/modules/2.4.26/kernel/drivers/net/b44.o: insmod b44 failed
