    I have a desktop running ME with a dial up connection, and a laptop running
    XP with a wireless connection to the desktop. I can transfer files in a
    limited way using the desktop (cannot use laptop to move files to the
    desktop, but can used desktop to move files back and forth to the laptop),
    and cannot get any internet connection for the laptop. Im using linksys
    wireless g WEP encrypted. Anyone know something I might not have set up
    correctly for the ICS? Also, I keep running into the XPs need to enter a
    password to access the shared files on the desktop. Any help is truly
    appreciated. Thanks.

  3. Hi
    If you connected the Wireless Router using the WAN port you created two
    segregated Networks and thus traffic goes only one way.
    The Wireless Router has to be connected through a regular port.
    This page describe the principle, http://www.ezlan.net/router_AP.html

    How do I go about doing that? I'm not that familiar with how to do that. Thanks.

    You don't seem to have set up ICS.

    You also should know that WEP encryption -- which unfortunately is the
    best you can do with XP in an ad hoc network -- is quite easily cracked
    these days. You really should buy yourself a wireless router. They're
    not very expensive, and in addition to permitting the use of better
    encryption, will provide you a layer of protection (NAT plus, in many
    cases, a built-in firewall) from Internet nasties.

    Here's a (now obsolescent) article by MS-MVP Barb Bowman explaining how
    to set up ICS using a wireless ad hoc connection:
    http://www.microsoft.com/windowsxp/using/networking/expert/bowman_02april08.mspx
    The article is based on XP, but I assume that ICS in WinME works similarly.

    Right now I'm more concerned about getting the network going than the
    security. I cant use a router because they require a high speed connection
    and I don't have that. Also, I do have ICS set up on the ME desktop
    already. What gives you the idea that its not set up? Is there something
    indicated in the ipconfig stuff or is this just a guess? Thanks, but I've
    tried looking at that webpage already.

    When you share an Internet connection with another network adapter using
    ICS, the second adapter (the one to which your LAN is connected) is
    assigned an IP address of 192.169.0.1. ICS includes a "DHCP Allocator"
    which assigns IP addresses (and the gateway address) to adapters on the
    local network. These are in the subnet 192.168.0.x

    Thus, when ICS is correctly set up, the wireless adapter in your desktop
    should have an IP address of 192.168.0.1 and the wireless adapter in
    your laptop should have an IP address of 192.168.0.x (2 <= x <=254) and
    a Default Gateway of 192.168.0.1.

    In contrast, the wireless adapter in your WinME desktop has an
    APIPA-type IP address of 169.254.4.40 and the wireless adapter in your
    laptop has a similar IP address of 169.254.177.184. Although these two
    IP addresses allow the two computers to communicate in an ad hoc
    wireless network, it is not an ICS network.

    This MSKB article describes setting up ICS in WinMe:
    http://support.microsoft.com/kb/229829

    Here are some manual steps that work in XP; I don't know how closely the
    correspond to what's available in Me (see
    http://support.microsoft.com/kb/306126/):

    1. Open the Network Connections folder.
    2. Right-click the ICSHARE Adapter connection.
    3. Click Properties.
    4. Click Advanced.
    5. Put a check mark in the box "Allow other network users to connect
    through this computer's Internet connection.
    6. If there's a box that says "Select a private network connection",
    click the arrow and select the wireless-G USB adapter connection.

    When you say network adapter, are you talking about a router? If so, this
    network doesnt have a router. It has a pci card and a usb adapter in an ad
    hoc network, there is no router. The two machines are set up to only talk
    to each other directly, not through a router. Its like having a crossover
    ethernet cable between them. They worked fine with the cable, and shared
    the internet connection. They just wont do it over wireless for some
    reason. Ill look into the IP addresses, but Im not sure that is the
    problem. The DHCP is what is assigning the IPs now.
    Thanks,
    Brian

    No, "network adapter" is the piece of hardware in a computer that
    permits the computer to connect to a network. It could be an Ethernet
    pci card (in your desktop, this is the HP EN1207D-TX 10/100 Family
    Adapter) or it could be a USB wireless network adapter (in your desktop,
    this is the Compact Wireless-G USB Adapter).

    Your desktop appears to have 4 network adapters. Because the one with
    the external IP address is called "ICSHARE" perhaps what you have done
    is to enable ICS but share the Internet connection with one of the
    network adapters that is NOT the wireless adapter, most likely the HP
    EN1207D-TX 10/100 Family Adapter. What I can tell, as explained below,
    is that you have not shared the Internet connection with the wireless
    adapter in your desktop.

    [I just re-read your post and saw the statement, "They worked fine with
    the cable." If you previously had set this system up using ICS and a
    cross-over cable and it was working fine, you almost certainly have
    shared the Internet connection with the Ethernet adapter in the desktop,
    as I guessed in the paragraph above. You have to re-configure ICS to
    share the Internet connection with the wireless adapter, and then things
    will work.]

    You say that "The DHCP is what is assigning the IPs now." It's is not,
    and that's exactly the point. "Normally," a DHCP server DOES assign IP
    addresses. But because you don't have a router, there is no DHCP server
    in your local network to assign these addresses.

    Your ISP has a DHCP server. It has indeed assigned an IP address:
    216.50.243.13. That IP address was assigned, by your ISP, to the
    connection identified as "ICSHARE Adapter." What is this device? As an
    aside, the IP address indicated for the DHCP server, 255.255.255.255, is
    incorrect, so there is something peculiar going on here.

    The IP address 216.50.243.13 identifies you to the Internet. For
    example, if you go to http://www.whatismyip.com/ (or a similar website),
    this is the IP address that will be reported (note that it may change
    each time you connect to your ISP).

    You can only connect ONE computer (at a time) directly to your ISP, and
    you only get ONE IP address from your ISP. The other computers in your
    "local area network" do NOT get their IP addresses from the ISP. These
    computers get their IP addresses in one of three ways:

    1. From a router, which has its own built-in DHCP server. You don't
    have one of these.

    2. From Windows ICS, which includes a software DHCP server (ICS calls
    this a "DHCP Allocator"). The ICS DHCP Allocator ALWAYS generates IP
    addresses in the range 192.168.0.2 to 192.168.0.254.

    3. From Windows itself. This is called "Automatic Private IP
    Addressing" or APIPA. APIPA addresses are ALWAYS in the in the private
    range 169.254.0.1 to 169.254.255.254.

    You are correct. Your computers are set up to talk to each other using
    the two wireless adapters instead of a crossover cable. These two
    adapters have IP addresses of 169.254.4.40 and 169.254.177.184.
    Although these two addresses are on the same subnet and can therefore
    communicate with each other, they are assigned by APIPA, and not by an
    ICS DHCP allocator. Thus, your computers can talk to each other, but
    they are not sharing the Internet connection.
