UNIX for Dummies Questions & Answers

I recently installed Caldera 2.4 (successfully ), but I cannot seem to get my cable modem up and running! My ISP is AT&T and I'm using @home. I've tried using DHCP and that didn't work either. I briefly read the cable modem HOWTO, but the lsmod didn't list my network card (3COM). What do I do now?

if you have about $80 - $100 extra to spend, I would suggest a dsl/cable router. (linksys, smc barricade).

they are easy to setup and you can have your LAN up and running in no time regardless of the host's OS.

the problem I've seen a lot is that the software they give you with your cable modem is just for windoze.

A DSL/Cable router is not going to help if the lan card is not working properly. You should get your network card functioning first. Make sure your card is supported (check the list of 3com cards here: http://www.linuxdocs.org/HOWTOs/Net-...54.html#AEN956). 'lsmod' may not list your ethernet card if the driver is compiled into the kernel. Check out the 'dmesg' command or look at the boot messages in /var/log/messages (or wherever Caldera puts them). You need to find out if the card was detected at boot-time.

if you have any of the newer 3com cards, they are almost guaranteed to work on anything. all of my 3com cards have been successfully recognized by redhat, mandrake, suse, bsd, and solaris 7,8 x86.

You should still be able to manually install your 3Com card. Check your manual that came with your OS and look for the <b>modprobe</b> command for your particular adapter. This will probably be something like <b>modprobe 3c90x.o</b> assuming your 3Com card is a 90x model. You might want to try the tulip.o module first since it is generic and most NIC's will be able to use it without a problem. You can get a list of NIC modules in <b>/lib/modules/2.2.19/net</b> or something similar; the 2.2.19 is my kernel so yours might differ, but there is usually only one subdirectory in <b>/lib/modules</b>. If you don't have a manual you should propbably search Caldera's site for more info.

Once you get your NIC up Cable modem is much more straight forward to set up then DCL from my experience.
