Sharing USB ADSL modem to a 2nd computer (Both XP)

I networked my daughters XP Pro machine to mine via a crossover cable
(works fine).I then quite recently connected a D-Link DSL-302G ADSL
modem via USB to my windows XP Pro machine. The first thing that
happened was that I found that if I disabled/disconnected the network
to my daughters machine I could access the internet perfectly well. As
soon as the network was re-established the internet was gone again and
at this time was not available on my daughters machine either (as you
would imagine).
I eventually found that if I selected both the "Local area connection"
(Ethernet network) and "Local area connection 2" (USB connected ADSL
modem) and "Bridged" them then I could access the internet from both
computers and no connections got upset about other connections.
Now, a month and a bit down the track, the network between the two
computers is still running flawlessly but the internet is refusing to
work on both machines at once. If it is working on mine and my daugther
uses her browser to access a website then my connection to the net goes
dead. She can use hers for a while without hassles until hers will
suddenly die without me touching my machine at all and mysteriously my
computer is happy to browse the net again. Has anyone a clue what this
could possibly be caused by ?

if the 302G is a simple modem then it can't handle two PCs.

The solution would be to use Internet Connection Sharing on the one
with the modem, sharing via the ethernet cable to the other. That
would give one PC the external IP address via the modem then its
ethernet would be 192.168.0.1 and the other PC would get an IP address
from the first.

Hi Phil... I will explain further... hookup is as follows:
[Modem]------<USB cable>------[computer1]------<cat5
cable>------[computer2]

Where computer 1 is my computer. The reason ICS doesn't work is that as
soon as you unbridge the two networks you get one network OR the other.
I have now disconnected the ethernet network and am able to use
computer 1 normally on the internet. Of course the moment I reconnect
my daughters computer it takes over if she uses her browser and I can
get no internet access at all.
If only the USB modem acted like a dial-up device so I could use ICS or
some proxy software !!!
PS the modem gets the external (real world) IP address and the modem
USB port for the internal network gets an address in the internal IP
address range.

Cheers
Chris

not sure what the sentence means ?

get a dos prompt by putting 'cmd' in the Run box of Start then
'ipconfig /all' on both machines to see the IP addresses etc.

ICS makes the PC act as a router, so it would pass traffic to the USB
modem from the ethernet socket if configured to do so. You need to
pick the IP addresses to suit, but ICS is what you need, BUT - see
below.

http://www.dlink.com/products/?pid=67 its a two port router not a USB
modem. At risk of sounding like a dork, why don't you plug the 2nd PC
into the ethernet port on the Dlink and the 1st PC into its USB port ?
as shown at
http://www.dlink.com/products/resour...&rid=322&sec=0

or better still buy a $10 hub or switch and connect two PCs by
ethernet to the DLink

I beat you to it Phil... already got a friend sending me an old 8 port
10 Mbps switch to get rid of the problem.
The other option you gave comes as a surprise because the supplier of
the modem said I could under no circumstances use both ports
simultaneously and was very adamant that it was it was either one or
the other.
Your help has therefore not been in vain as I have learned not to trust
the phone support people when it comes to hardware. Thankyou very much
for your help today.

Unless you feel strongly they deserve to remain anonymous, it might be
of help to others to know who supplied it and gave duff information !!

UK ADSL <http://tinyurl.com/5jpa4> - Happy to save cash with Plus.Net!!

It was my service provider of course... (just take a look at the domain
name on my email address)
I don't think it will take them long to figure out who I am ;-0
To tell you the truth they are probably the best of a bad bunch.
Nothing out of the ordinary there no doubt, it seems many countries
have dodgy telcos.

Ah, I didn't look at the mail address, and wrongly assumed you were in
the UK, with your post being in uk.comp.home-networking... How likely
is your ISP to spot the post in a uk.* group after all :-) Peter M.

A quick Google suggests otherwise:

"Two computers can simultaneously connect to the DSL-302G through its
USB and Ethernet port to share its high-speed Internet connection. You
can connect to its Ethernet port regardless of the operating system you
are using, or connect to its USB port to allow easy installation to a
USB equipped computer running 98SE, Me, 2K, XP, or Mac OS 9 and OS X."

btw I have connected both computers, one by USB and the other by cat5
and both are connected to the net fine now.
Thanks for steering me in the right direction.
btw a quick google on the isp's name brings the message straight up
without specifying more advanced options than "Only messages in the
last week" and "English" so it is pretty easy to find in the UK group.
The reason I posted in the UK group was because it was the first group
I found that was talking about the type of stuff I was having problems
with.
UK, Japan, USA.... it is a small world with the net :-)
