I am trying to use my Toshiba 2600 cable modem under XP Pro the same
way that I used it with 2000 Pro and it won't work.

Here is the scenario: My computer is on a cable modem, using USB
connection to the Net. The NIC card in the computer goes to a router,
that is wired to all the other rooms in the house. The network is for
LAN purposes ONLY and I am not sharing the Internet connection at all.

All this worked fine under 2000 Pro.

Now I have installed a new HD and put XP Pro on the machine, which is
the same OS on my wife's machine at the other end of the house. I
figured that networking would be easier if we both used the same OS so
when I put in the new hard drive here, I used XP.

Problem is that the machine will only connect to the Internet if the
lecal network is disabled. I have my choice of the Internet via the
USB Cable modem or the LAN. Cannot do both at the same time.

Toshiba tech support told me to have my ISP reconfigure the cable
modem on their end because after I installed XP, I could only get on
the Net if I used the CAT5 connection on the modem. Even though all
my other USB devices worked, I could no longer get on the Internet via
USB - and that's what they told me to do. It worked fine; I am on the
Net now via USB but the above problem exists. I have to disable the
NIC card or unplug it in order to be on the Internet.

Toshiba Tech support has no further suggestions.

HELP!

Why a router? Do you mean the router has a multi-port
hub/switch built in or are you really using it as a router?
What protocols are you using for your LAN? What are the IP
addresses of all the computers, router, etc? What default
gateway and masks do you have in place?

You surely wouldn't expect to be able to simulataneously
connect to the internet via the USB modem and LAN?

Yep, my preferred option would be to have the modem
connected to the router using CAT5.

This does not make sense. Are you connected to the modem via
CAT5 or USB? In the previous paragraph, you said that you
had to use CAT5, now you are talking about using USB.
If you only want access to the internet from one machine,
use NetBeUI (or IPX if you must) on the LAN machines and
only have TCP/IP in addition on the machine that needs
internet access. That should solve any problems of your LAN
settings interfering with your WAN settings. Get your LAN
working first.

Then configure the router properly. It must have its address
set as the default gateway address under IP on the computer
that needs internet access. If the router has firewall
capabilities, set them up.

Plug the modem into the router using CAT5.

That's very bizarre. Installing a new OS on your computer should have
absolutely NO effect on the function of your cable modem.

From what I understand, Toshiba recommends you use the ethernet
interface with Windows XP.

I woudl suggest you chuck another $10 NIC in your computer and hook up
the cable modem to that.

Alternatively, run the cable modem directly into the router. You
mention that you don't want to share the connection to all the other
computers; there are ways of configuring routers (and/or computers) so
they don't work entirely properly. You could bust things just
enough so that you get local network traffic working fine but no
internet for the other computers.

Don't worry, I'm sure he also has a SCSI interface.

ROTFL!

Why not? It does have a 5-port switch on it. The network is setup
using TCP/IP and yes the hardware is set up appropriately. I've
changed IP's and configs so I don't know what they are currently set
to. Last thing I tried was having XP make a network setup disk but
it did not work either.

NO! NOT what I want. I want the local network to be able to share
files etc but the USB port is for Internet only.
I only mentioned that because it happened that's all. I am using USB
NOW but originally when I set XP up, it would only work with the CAT5
connection.


Thanks

I asked why a router in case you were using it as a router
rather than as a switch - e.g. to split your LAN. Just
trying to understand your configuration. I think you are
just using it as a switch, is that so?
I think that you may have had a second protocol loaded under
2kPro (say NetBeUI) and that was why it was ok then.
Changing to XP removed that protocol.

This still sounds like you don't have your TCP/IP settings
correct on all the machines. Hence my suggestion to use a
different protocol for your LAN than your WAN. If that works
OK, then it is almost certainly the TCP/IP settings that
need to be sorted out. You can sort out these and then
remove the second protocol - but at least while you are
sorting out TCP/IP you will have LAN connectivitiy.

Beg your pardon, but on this computer with that modem, the USB port is
NOT for internet. Toshiba recommends you do NOT use the USB port on
the cable modem to connect WinXP machines. See my other post in this
thread. Therefore, you should use an ethernet connection. You want
to connect your computer directly to the cable modem? Per my other
post, throw another NIC in your box ($10, cheap) and off you go.
Unless you have some reasons for preferring NOT to follow Toshiba's
advice?

Palindr?me's other suggestion -- to run your cable modem in through
the router, and have TCP/IP on your computer whilst the rest use only
NetBEUI, would also have the desired effect of giving only your
computer internet access. It would have the added benefit of giving
you an extra layer of security.
