Moved from ADSL to Cable. How to set up?

Hi all. This will be a bit verbose, but generally, the more info I
give, the easier it is for someone to understand the issues.

I've recently moved from a fully working set up in the UK to Israel,
where I'm out of my depth, and don't understand the language either -
so anyone who could help me here, can't tell me what to do anyway.

In the UK I had a D-Link DSL-G604T ADSL modem/router, which I connected
to the internet via the UK landline phone lines. I then had 2 computers
and my IPAQ all connected wirelessly to the DSL-G604T and all could
communicate with each other, and use the internet. Computer 1 (which
I've brought with me) had a wireless card installed, Computer 2 had a
USB dongle attached, and the IPAQ has its own internal device for
receiving anyway.

Now I've moved to Israel, and I've brought with me Computer 1. the
DSL-G604T and my IPAQ.

My host has a cable modem a TERAYON TJ715 which means I can't just
replace her modem with my DSL-G604T.

Here come the questions:
I have my own thoughts about how I could do this, but it would be much
better if someone who knew what they were doing could save me
travelling up blind alleys.

1) Is it possible to use the DSL-G604T solely as a router, since the
modem side of it is superfluous now? If so, should it be attached via a
cable to
a) my hosts computer,
b) my computer)
c) directly to the modem via the ethernet port on the modem, bearing in
mind that there are warnings on the modem about not connecting the
modem via usb (which is how it connects to my hosts computer at
present) and the ethernet port at the same time.

2) Would it be possible to attach the cable modem to the DSL-G604T,
leave them both on permanently, and then access from any computer
without my hosts computer having to remain on permanently.

3) Would I be better off by purchasing a cable modem equivalent to my
DSL-G604T? (i.e. both a modem and router) If so, what are the
implications with the service provider. If passing this test, can
someone suggest a suitable make/model. Most of the main brands are
available here, but I know for certain that I can obtain D-Link and
Linksys.

I have a couple of wireless cards available, so I'm not concerned with
that side of things.

D-Link have recommended a networking program which I'll use to get it
all set up, so the software/addresses/security/protocols are something
that I'll leave until I've got all the machines capable of talking to
each other.

Many thanks to all who take the trouble to respond.

No. In order to do that, you would need to have access to the
ethernet connection between the DSL modem section, and the ethernet
router section. This is not available in the DSL-G604T. Sorry.

You can use the DSL-G604 as a wireless access point (no router, no DSL
modem). You would still need a router somewhere. Not recommended.

Sorta. If you connect the Terayon cable modem to a LAN port on the
DSL-G604T, you will get a direct wireless bridged connection. However,
you will not have a router in the path, even though there is one
inside the DSL-G604T. This will sorta work, but I would not recommend
doing it this way.

No. The most versatile arrangement are seperate boxes for each
function. Your host already has a cable modem. Do they also have an
existing router? If they do, just setup your DSL-G604 as an access
point and you have instant wireless using the existing cable modem.
1. Connect to one of the LAN ports. Watch the cable polarity.
2. Setup the IP address of the DSL-G604T to not conflict with the
exiting router. If the existing router is at 192.168.1.1, setup the
DSL-G604T at 192.168.1.2.
3. Disable the DHCP server in the DSL-G604T.
4. Do not plug anything into the DSL line port.

If they do not have an existing router, you get to buy one. I don't
like combined router/wireless boxes because the router wants to live
where all the wires come together (under a desk, in a closet), while
the wireless wants to live in the open and as high as possible. These
are mutually incompatible. Unfortunately, seperate boxes are about
twice as expensive as combined router/wireless boxes.

What networking program?

Does your host have an ethernet port that can be used instead of
the USB connection? It may just be simpler to get a wireless router (like
the DI-624 or WBR-1310) and gift it to your host, and use that. You would
then plug the cable modem's ethernet into the router's WAN port, wired
stuff would go directly into the router LAN ports, and you'd have
wireless.

If your host doesn't have an ethernet port available, consider a
USB<->Ethernet dongle (like the DUB-E100).

Jeff, thanks for replying.
I think the simplest thing for me to do is to buy a wireless router. I
had a look at the linksys WRT54G instruction manual online and it seems
to fulfill my requirements.
i.e. I can switch my hosts computer off, and as long as the modem is
left on (and of course the router), then I can use either my own
machine or my IPAQ independantly. Also, it doesn't seem to breach any
setup with the cable modem.
I've looked through my hosts machine for all the settings I can find,
but perhaps you could advise me of which settings I'll need for certain
to do it this way. I could do without having to call the local ISP and
trying to find someone who a) speaks English, and b) is able to help me
without telling me that what I should have done was call them to pay
rental on an overpriced system!

Again, my thanks.
Regards,
Howard

Sorry, forgot to mention that the program is called "Network Magic".
It's downloadable for free at http://www.networkmagic.com/

Sounds like a plan.

Make sure you do NOT buy a WRT54G or GS version 5.

http://www.linksysinfo.org/modules.p...wtopic&t=10230
You can tell by the serial number prefix. v5 has problems.

Correct. All you need is to have the modem and WRT54G turned on. The
hosts computer is not required.

>Also, it doesn't seem to breach any

Maybe. If your ISP authenticates by the MAC address of the client,
the connection will fail. The solution is simple. Connect from the
original (hosts) computer normally, with the router installed. Find
the place in the WRT54G that mumbles about "Clone MAC address" for the
WAN connection. Save. Power cycle everything. It should now work.
Hopefully, this will not be necessary.

Time to learn Hebrew perhaps? Most ISP's have their policies and
proceedures posted on their web pile. If there's a rental or leased
computer in the system, there may be some security complications. Hard
to tell until you try it or until you call them and ask.

That's from Pure Networks. Parts of Network Magic are included with
AOL 9. A limited version is free or $30/year for the full version.
I've played with it and found it useful. The free version doesn't do
much more than what you can do manually with XP, but does make it
easier by putting most of the important networking setup menus in one
place, instead of XP scattering them all over the place.
http://www.networkmagic.com/product/network-setup.php

However, it does absolutely nothing for dealing with hardware
configuration issues on routers (other than automatically punch holes
in the router for port forwarding for AOL). There's no way this would
help you get all the hardware working, but might be useful in
"managing" the network afterwards.

Thanks again. I was under no illusion that this would be an all singing
all dancing "I can set up any system as though by magic" utility.
Especially at the "price"! But parts of even XP are as friendly as a
cornered rat when it comes to setting up wireless networks, especially
to someone whose sole experience is one computer system. So anything
that makes life easier is welcome.

I've posted a new topic, see bomb proof walls, which may make this
whole conversation redundant. Shame if thats the case, cos I'm up the
creek without a paddle if the warning I had is correct.
