JJ,

What is the laptop getting the internet connection from?

Please provide ipconfig information for the two computers. Start -
Run - "ipconfig /all >c:\ipconfig.txt" - Open c:\ipconfig.txt in
Notepad, copy and paste into your next post.

Is that your actual email address in From:? Learn to munge properly.

Thanks for getting back to me, and thanks for the munging article - much more effective than simply holding onto my hotmail account as a return address e-mail.
I can't run ipconfig, the standard looking c:\ screen pops up, but only for about a second (i'm runing XP on both computers).
The laptop connects via a wireless network connection using a d-link wireless usb adapter.

JJ,

Try Start - Run - "command". Then enter
"ipconfig /all >c:\ipconfig.txt" into the command window.

Please provide some detail about your network. What is on the other
end of the USB - wireless network connection on the laptop? Why not
just connect the laptop and other computer as peers?

[JJ]

I am not at home now, so I can't get you any further info on the computer except that the laptop gets the wireless from a cable modem.
How do I connect the two computers as peers?

[Chuck]

Put a wireless USB network device on the second computer, and let it
connect directly to the wireless device attached to the cable modem.

JJ,

OK, I see the situation. You have a WAP (wireless router / access
point) attached? to the cable modem, using ip address 192.168.0.1.
That's why you get an error that the IP address is already being used
when you try to use ICS.

If you're going to use "laptop" as the gateway for "BEDROOM", you'll
have to use some sharing software in laptop. To use ICS, you need to
change the ip address of the WAP using 192.168.0.1 to something else,
and reconfigure the USB adapter on laptop (DHCP client so not terribly
difficult). Then you can setup ICS using the Xircom at 192.168.0.1
connecting by Ethernet cable to BEDROOM. BEDROOM then gets DHCP
services (including the gateway address) from laptop.

Putting 192.168.0/24 subnet on the Xircom to BEDROOM subnet, you'll
need to use another subnet, say 192.168.1/24, for the cable modem WAP
to D-Link USB subnet attached to laptop. If you just change the cable
modem WAP to say 192.168.0.2, you'll have a DHCP server on
192.168.0.2, and another on 192.168.0.1 (ICS). If you don't setup a
bridge betwen the D-Link and the Xircom, that might work. Or you could
turn the DHCP server on the WAP Off. It's your choice.

OK, try it like this:
1) Reconfigure the IP address of the WAP to 192.168.1.1. Restart
laptop, see if it gets a new ip address and can get internet.
2) Setup ICS on laptop. See if BEDROOM connects, gets an ip address,
and can get internet.
3) If that doesn't work, setup a bridge between the D-Link and Xircom
adapters in laptop. I've never used a bridge in XP networking, so I
don't know what that does to internet access in laptop, but give it a
shot.

Let me know what happens please. I wish I could be there with you and
see it in person.

Cheers,

[JJ]

Unfortunately, I can't mess with the WAP because the cable modem is my buddy's. I tried to use a network bridge, and here is what happened:
I highlighted the Local Area Connection and the Wireless Network Connection and right clicked to select the create the bridge. After it completed a network bridge was created, but it said that the network cable was unplugged. When I clicked the properties of the network bridge, none of the adapters where selected. I then selected the Local Area Connection and the Wireless Network Connection and both moved to the bridge and were enabled, as was the bridge itself. Unfortunately, I could no longer connect to the internet on the laptop, and nothing changed on the PC. Now what?

[Chuck]

JJ,

I had a feeling that one of the constraints was that you don't own the
cable modem / WAP. That just means you can't use ICS. But a proxy
server might work for you.

Remove the bridge. Download Analogx Proxy Server (free) from
<http://www.analogx.com/contents/download/network/proxy.htm>. APS
isn't transparent like ICS. ICS creates a gateway - APS you have to
configure on the client (BEDROOM) - in each network program (browser
etc). Things like Instant Messengers may or may not work with proxy
servers.

You can use DHCP on the D-Link on laptop, cause it will continue to
get DHCP and everything else from your bud's WAP. The Xircom on
laptop, and the Kingston on BEDROOM you'll have to allocate ip
addresses and setup manually (NO DHCP client) - try 192.168.1.1 and
192.168.1.2. I don't think default gateway is relevant for either -
APS will take care of both - use 192.168.1.1 if you have to give one.

On BEDROOM, in Internet Explorer for instance, go to Tools - Internet
Options - Connections. Follow instructions for proxy server
configuration. I've setup enough proxy clients - but none in WinXP so
I have no idea what the wizard is like. Good luck there.

Well, JJ,

You have now exceeded the limits of my experience with the Analogx
Proxy Server.

I used APS for many months, when I had dialup and multiple computers.
One of the reasons why I got a NAT router that supported dialup was
the difficulty of using Yahoo Messenger on the proxy client.

Looking at the APS documentation, it looks to me like SocksCap is for
programs that don't support proxy server usage at all, not for Yahoo
Messenger that does support proxy server usage, but probably just for
text conversations. As the documentation reads to me, you have to
start the non proxy compatible program from the SocksCap interface, so
the program in question runs as a subtask of SocksCap. I don't know
that you can do that with Yahoo Messenger.

If you look at the documentation with APS, you'll see that it has a
small list of protocols that it supports. One of the limitations of
proxy servers is that they work only for specific protocols that
they're written for.

All the listed APS protocols are low QOS (Quality Of Service)
applications like web browsing, email, usenet, file transfer, all
things where latency doesn't matter as much as with webcams and web
voice. Yahoo Messenger text chat is low QOS, like web browsing.
Yahoo Messenger webcams need higher QOS. Microsoft (MSN / Windows)
Messenger webcams use still higher QOS and are harder still to work
with NAT routers.

You might get better results with another proxy server. Download.com
lists 139 possibilities if you just search on "proxy server". I
wouldn't count on all of them being solutions, but you might find
something better than APS. Tucows.com is another shareware site you
might try too.

Short of a proxy server being a solution, you might consider getting a
NAT router, and an Ethernet connected WAP, that you could connect to
the WAN side of the router. Using a router to share the internet is a
much better solution in so many ways.

Which brings us to our final possibility. Buy another WAP, this one
with an Ethernet interface, put it beside your laptop, and connect the
long cable to BEDROOM to it. Use your bud's router for the sharing.
Of course that would leave you sharing your files wirelessly, which is
a huge security risk.

Want more advice? I generally have my Yahoo Messenger up 24 x 7. My
nym is rzurcetin (read nym in mirror).
