You don't give us enough information to identify a problem, so the best I
(and probably others) can do is to point you in the direction of some things
you should check in order to isolate where in the sequence of things the
problem lies. If you haven't forgotten some hardware change you made (aside
from the CD-ROM, which will have no effect, assuming we are talking about an
ATAPI drive connected to a normal IDE channel), then almost surely you made
some small error in dong the setup ... unless your ISP made a change and
forgot to mention it to you (not impossible, since they tend to assume
everyone has Windows).
Still ....
1. Is the Ethernet card properly configured? If you run "ifconfig", does it
report an active eth0 (if not, you need to figure out why modprobe isn't
finding the card where you think it is) and does that interface have the IP
address, broadcast address, and netmask it is supposed to have (if not,
check your network settings)?
2. Is the default route set correctly? I don't know cable modems, but this
should be the IP address either of the modem or of the gateway it connects
to at the other end (in any case, it should be the same as it was before the
reinstall). Check this with "route -n".
3. Do you have a working cable between the NIC and the cable modem? I don't
know if cable modems are designed to take a regular or a cross-connect
10BaseT cable; be sure you have the right one. (One way to check is: can you
ping the cable modem itself?)
4. This is a long shot, but ... is it possible that you have an IRQ
conflict? IRQ 5 is normally a parallel-card IRQ. I've seen other instances
where an IRQ conflict goes undetected by the kernel, with the result that
Ethernet TX frames get sent but RX frames aren't received.
