Did you in fact configure TCP/IP properly? You must assign a static but

Yes


I don't remember if Win98 had an "ipconfig" command, but open a DOS
window and type that and see what you get. It should report back the
network info of the PC.

I am getting this--not sure why I am showing so many IPs. For the record
I have 2 network cards on Computer A (one for the cable modem, one I
installed yesterday for the network) and a new one of Computer B:

If all this checks out, then swapping out the crossover cable for two
straight cables and a hub is not a bad idea. There have been reports of
situations where, for whatever reason, a crossover cable didn't play.

Think I am just going to give up instead. :-(



Nah - don't do that.

Do you know which ethernet adapter is which?

If you want to connect the two computers so they can both use the Internet
connection then you're going to need a small hub of some type. The cost
shouldn't be more than $30 for a small switch/hub. If the idea was to be
able to find a way to connect the second computer to the Internet then it
would be hard to do by dual homing a Windows 98 machine (using two network
cards in one computer). When you do that you're effectively trying to use
one of the Windows 98 machines as a router and that's a bad idea.

You'll want one network card in each computer. Connect the ethernet card in
each computer to the hub/switch as well as the ethernet connection from the
cable modem to the hub/switch. All the computers will be able to see each
other through the hub as well as access the Internet through the hub.

For the IP configuration you'll need an IP address, subnet mask and default
gateway for each computer. You'll also need the DNS numbers from your cable
company. On the Windows 98 computers in the network configuration make sure
the WORKGROUP name is the EXACT SAME on both computers. They should not be
set up to be part of a domain. You'll have something that looks lie this:

Computer 1:

IP : 192.168.1.1
Subnet: 255.255.255.0
Gateway: this will be the IP of the modem

Computer 2:

IP: 192.168.1.2 (the first three numbers have to be the same for this mask,
the fourth will be the distinguishing number)
Subnet: 255.255.255.0
Gateway: IP of modem

For the DNS numbers you can get these from the cable company and put them in
the network configuration. You'll probably also need to call your cable
company to see how they want you to set up for multiple computer access.
Basically what happens is your computer (network card) will first look at
the internal network to see if it can find the address you want to access
(it does this using the subnet mask). If the address is not on the internal
network it will send the packets out the gateway (the default path for
anything it can't access internally). In order to find the path to the
external address you want to access the router/computers will use the DNS
servers provided by your cable company.

You'll need straight through cables for this, nothing expensive just your
basic Cat5. The switch/hub will either configure itself internally for the
connections or it may have an 'X' connection - this is where you will plug
in the router and the crossover occurs in the internal circuitry of the
hub/switch. For example, if you see some ports numbered something like 5 and
next to it 5X then the modem would get plugged into 5X and NOTHING could be
used on the port labeled '5'.

Make sure to call your cable company because I've seen different setups for
different DSL/cable companies. The object is to get the router with an IP
address (which is given by the cable company) on the same subnet as the rest
of the internal network so any computer that wants to access an outside
network knows where to find the router so it delivers the packets across the
internet connection. You may even be able to find some type of setup
configuration on the cable company's website. Which company do you use?
