    Every time I try to do this is screws up the modem and I have to reboot it.I know it can be done because I've seen it but I am apparently doing something wrong. They had it at work, two NICs in the master PC in the office then that fed a router and thus all the other PCs in the shop.

    The basement PC acts as a server, has XP Pro on it and my printer. It's a biggun so it lives in the basement. There used to be almost a TB in it untilone drive went bad, but I'll deal with that later. It still has most of mybest media and porn on it.

    That one is on wire, as is a newer PC with XP Pro 2nd floor. Also one laptop running Vista on wireless and one running Win 8. Intemrittently there is a MAC on wire and another Vista on wireless. Once in a while there is even another one using Win 7 on the wireless.

    Everything seems to work, but now I have this other Win 7 PC that I am trying to get online without disconnecting anything. It is not equipped with a wireless card. The laptop on wireless was first. I tried to just let it connect on air, and then share the internet connection via wire with the "new"Win 7 PC. When I did that the whole thing went down.

    Next, I take it downstairs, put a second NIC in the basement PC, turned on ICC and poof, same thing. Had to reboot the modem again.

    What the hell am I doing wrong ? The first NIC is onboard, an Nvidea nForce.. The one I added was a Realtek with a RTL8139B chip on it. Device manager said everything was fine.

    This last time I had to do a system restore on it just to get it to connectagain even after rebooting the modem.

    The modem has the router built in and the wireless, it seems to be a Pace 4111n, supplied by ATT. This has, however, happened on others.

    What am I doing wrong or not doing here ? I want to avoid buying a wirelesscard (or using another channel) or using the last RJ45 on the modem. I might eventually use that for the printer.

    Whatever way it works, I would like to have an extra wire hanging around for any PC I might want to hook up in the basement.

    I don't believe it's because there is a newer OS connecting through an older OS because it didn't bother the system at work. I connectd a Vista laptopto the router that was connected to the XP "main" PC in the office and it worked fine. I did not set that up, the computer "guru" did. He is not available anymore.

    When connecting one computer to another, you might need a "crossover" Ethernet
    cable. Both computers should have the LEDs at their Ethernet jacks lit and
    (probably) blinking. If not, you definitely have a problem.

    Windows has a feature called "Internet connection sharing" (ICS), which is
    probably what you should be using. The following is from "Windows 7
    Annoyances", p480ff. (BUY THIS BOOK. You need it.)

    Now, if you don’t have a router, or you want to follow the steps in the
    “Quick and Dirty WiFi Piggyback†on page 451, you can use the Internet
    Connection Sharing (ICS) feature built into Windows, along with at least one
    cable. To get ICS to work, you’ll need the following:
    • At least two computers, each with a network adapter properly installed
    and functioning. ICS can be used with both conventional and wireless
    • One PC must have an Internet connection properly set up, as described
    in “Internet Me†on page 476.
    • If you’re sharing a broadband (DSL or cable) connection, the PC with the
    Internet connection must have two network adapters installed: two Ethernet
    cards, or one wireless adapter plus one Ethernet card. See Figure
    7-20, earlier, for a diagram of this setup.
    If your Internet connection is accessed through a router
    or you’ve allocated multiple IP addresses, you don’t need
    The first step in setting up ICS is to configure the host, the computer with
    Internet connection that will be shared:
    1. In the Network and Sharing Center, click the Change adapter settings
    link to open the Network Connections window. If you haven’t already
    done so, open the Views drop-down and select Details.
    2. Here, you should have at least two connections listed: one providing your
    Internet, and the other providing access to your LAN. If they’re not there,
    your network is not ready. (For clarity, rename the two connections to
    “Internet Connection†and “Local Area Connection,†respectively.)
    3. Right-click the connection providing your Internet, and select Properties.
    This is either an Ethernet adapter plugged into your DSL or cable
    modem, or—if you’re using PPPoE—your broadband connection.
    4. This step is optional, but may be required if there are any PCs on your
    network running Windows 98 or older versions: follow the steps in
    “Troubleshoot Network Connections†on page 469, to set the IP address
    of the host PC to
    5. Choose the Sharing tab, and turn on the Allow other network users to
    connect through this computer’s Internet connection option, as
    shown in Figure 7-22. (The Sharing tab will be absent if there’s only one
    network adapter.)
    6. Click OK when you’re done. Verify that Internet Connection Sharing is
    enabled; among other things, it should say Shared in the Status column
    of the Network Connections window.
    That’s it! The change will take effect immediately, and you won’t have to do
    anything special on the client PCs. Verify that the Internet connection still
    works on the host by attempting to open a web page, and then try it on each
    of the clients.

    "When connecting one computer to another, you might need a...."

    I wonder. From what I remember, more modern NICs have auto crossover which should eliminate the need for a crossover cable. However this Realtek NIC Igot here might be too old for that. It does say 10/100 so it's not quite 286 days, but it doesn't say10/100/1000 so it's not quite a spring chicken either.

    I'm sure the NIC in the Win 7 box has it, but do BOTH NICs have to have it or just one ? I would think just one would do it but I could easily be wrong.

    I remember at the shop, the one guy actually made a crossover cable. He hadthe crimper and all, I asked him which color wires go where and he said deosn't matter as long as they're the same on the other side, however, for a crossover cable the middle two are switched. I could concievably make one, just cut and splice oe of the spares laying around here. I know it's not quite Kosher to splice this stuff but it should work and I have a motto : If it works it is good.

    I was on another forum somewhere and all I got is how this is not the rightway to do it. I don't know how many times I have to tell people, if it works it is good. I don't care if it causes globbal worming or whtever. Tell me about viruses and all this shit, that doesn't matter. I don't even use virus protection, I just watch what I do and I almost never let anyone touch my computers. what's more the reason for this is so I can transfer files toother PCs via the network rather than screwing around burning disks or copying to those USB thingies.

    Yes, when I fix or restore your PC you have the option of having more porn than the internet lol. Seriously, I have what you might call an "offsitre backup" for a few people's bought and paid for porn, just in case of course :) I can drag and dropya a nice little collection. Music too, rare stuff, not stuff you can get on youtube in five seconds. (although there is more and more these days) Also a bunch of portable programs like an image editor that does a screen capture that respects NOTHING. Makes a nice little document "editor" as well, in case you "discovered" a mistake on your birth certificate or a tax form or something..... Along with a the laser printer you can have that new Caddilac if you dare. And usually I throw in the normal VLC and Irfanview.

    In fact that is kinda what I want this ICS for. I want to see if these old apps will run. The Win 7 box is full 64 bit, and I've heard that some programs will not run if they were designed for 32 bit "environment?". Plus I think I want to sell it because Win 7 doesn't seem to be for me. I figured I would grab up all the good free software as well when I get around to it, like Openoffice etc.

    But in the end I want the cable just hanging there ready to connect anything. Perhaps even a smart TV if I end up working on one. I'm kinda curious about how all that works, the TV is a PC or what ? Just something to play with in my old age. Hell, now I have seen an RJ45 on an audio amp.
