    I have 3 machines, all with 802.11g cards, mine connected
    to internet. Workgroup set up, all can access internet,I
    can access their shared folders, they can access mine,
    but not it would appear each others.
    Have tried disabling firewalls but to no avail. Is this
    the correct mode of operation?

    If this is the case, how do they set up so can play LAN
    games with each other. Do I have to create another SSID
    on another channel for them to connect (not sure how)?

    Assistance appreciated.

    you should be able to play lan games by entering each machines ip in the
    games' menu

    Thanks Mike, originally tried letting wireless cards set
    own IP, but then tried setting statically. Still cannot
    get their machines to see each other's shared files or
    join when direct addressing in games.

    Have you set up with static IP's? if so you may need to enable netbios.
    (Advanced tab of TCP/IP properties then click on WINS tab)

    Some older games need IPX/SPX

    try adding IPX/SPX protocol.

    Go to start>>connect to>>show all connections
    right click on Local area connection and select properties
    click on install then click on protocol and add
    select ipx/spx

    You should now have an item called NWLink IPX/SPX/NetBIOS.....

    Click on it then click on properties. Change the internal network number
    from F000000 to a unique number (e.g change the last digit to 1 to make it
    F000001 and then on the other PC change the last digit to 2 - the number has
    to be different on each PC)

    Change the frame type from auto to Ethernet 802.3

    The network address needs to be the same on each machine so change it to
    something like 10 (it will change to 0000010 when you press okay)

    Cheers Tony, had checked the WINS setting but misread
    the default. Will give it a go. Using new games (Dawn of
    WAr) so dont want to get into IPX/SPX if can help it.
    Currently got two machines upstairs linked by cable, each
    bridged to wireless cards to access my machine
    downstairs. Seems a lot more to this wireless network
    than the experts let on. Have checked out loads of
    internet links and forums, though this most useful.

    Can you confirm it should be possible with ad-hoc network
    that 3 machines should be able to see all shared files or
    does the one with the internet access act more like an
    access point?

    Thanks for your advice.

    Three PC's set-up in Adhoc mode should be able to see each other.

    You shouldn't need the cable connection between the two machines upstairs.
    They would have to have a different subnet for the cable connection to that
    used by the wireless adhoc network. I feel that the cable connection is
    complicating matter.

    If you disconnect the cable (also you would have to disconnect the bridge to
    the cabled connection and I would disable the NICs that the cable connection
    uses) can the two upstairs ones see each other then?

    I would get the wireless network working first. Without the cable
    connection, you should be able to activate ICS which will allocate an IP
    address to each which will come from the main PC connected to the network

    Tony please see original.

    Have tried using Windows to setup connection using USB
    flash device (which didn't work - entered details
    manually) and tried using the X-MICRO WLAN software
    provided with the cards. It's almost there, everyone has
    internet access through mine, they can both see my shared
    files, I can see both theirs, BUT, they cannot see each
    others. Have tried the reset TCP/IP using netsh ip reset
    and started again but same problem. Still have wireless
    problem of connections dropping frequently but that's a
    seperate problem probably due to WZC.

    Any advice most welcome, your time appreciated.

    Sorry, I can't find original.

    I've just duplicated your set-up. I have three PC's all wireless networked
    using Adhoc and ICS. All can see each other, connect to the internet and
    share files. I then joined the two together that are not connected to the
    internet using a cable connection. Strange one found an IP address using
    the DHCP but the other wouldn't so I allocated it a static IP. I then tried
    to bridge connections on the two that had the cable connection but wasn't
    allowed - warning was cannot bridge to a connection that is using ICS. Even
    without the bridge they are working fine - both can see each other as well
    as the internet as well as the PC connected to the internet.

    I don't understand why you need the cable connection if all your PC's are
    connected using wireless? As I previously advised, disconnect the cable
    connection, get the Adhoc working first with all PC's seeing each other.

    Once that is working, connect the cable and manually allocate IP's and
    subnets but don't bridge. Suggest that you use a different subnet such as for the nics connected to the cable to keep it separate. Only
    thought I have is that will allow the two upstairs ones to still share files
    etc if the downstairs one is turned off.

    All are using USB wireless adaptors, two upstairs are using Belkin and
    downstairs is using a Linksys. All PC's running XP pro. All using WEP and
    zonealarm although the PC with internet connection has Internet Zone
    security reduced to Medium else others won't connect to the internet when
    using ICS.

    Tony, thanks again for reply. Only introduced cable to
    get around problem of the two machines upstairs not
    seeing each other. Now with the extra confidence
    provided from your reply that it all SHOULD work, I will
    kick the kids off again and have another go soon armed
    with a printout of your reply.

    Something I have noticed is that if I disconnect the internet, the other two
    don't reconnect whilst in Adhoc mode. The only way I found of reconnecting
    is to right click on the wireless network icon in the systray and click on

    If I disable the wireless adapter on the upstairs two, it is still
    connecting through the cable which I have given static IP's and changed
    subnet to

    Must admit I don't like ICS and don't usually use it. A proxy server such
    as CCProxy would probably do a better job but that's something you can look
    at when you get the network working!
