Thread: issues with ad hoc wireless configuration

  1. issues with ad hoc wireless configuration

    I have two PC's at home: a Dell desktop connected via ethernet to a Comcast
    cable modem, and a laptop with a wireless card. I have enabled ICS on the
    desktop PC and have been running an ad hoc wireless network between the two
    PC's. The laptop has been able to access the internet through the host PC
    with no problem.
    This weekend, however, suddenly the connection stops working. My girlfriend
    was trying to join the ad hoc network from the laptop PC and it gave her some
    kind of configuration screen. Now, I can see the ad hoc network from the
    laptop, but when I click "connect" it says "connected" but gives me an IP
    address of 0.0.0.0 for a few minutes, at which point it gives me an APIPA
    address of 169.x.x.x. As you can probably guess however, there is no
    connection netween the two PC's at this point....I cannot access the internet
    through this ad hoc connection, and the folders I had shared between the two
    PC's are no longer visible from either machine.

    It is worth mentioning, that the laptop PC can still connect to the internet
    through any one of a number of unsecured WAP's that are within range of our
    apartment, so it is not simply an issue with her wireless configuration
    settings. Also, the desktop PC is still connected to the internet, etc. I
    had not changed any settings on the desktop PC before this happened, so I am
    in the dark about how to proceed or what could have caused the issue in the
    first place.

    If someone could make a suggestion to help with this issue it would be much
    appreciated.

    Sorry, I forgot to mention that both PC's are running XP SP2.

    First, you should not be using someone else's unsecured connection.
    YOU can be prosecuted for this. Second, you really should buy a
    router for a few reasons:

    1. It is far safer because most routers have a hardware firewall and
    statefull packet inspection.

    2. You don't have to always leave the desktop connected

    3. Routers support better wireless security than XP ad hoc
    networking (WPA2).

    You probably need to disable ICS on the desktop and start from
    scratch and setup the ad hoc connection from scratch.

    This is a superior solution to Ad-Hoc and it cost less than a fancy Burger

  5. RE: issues with ad hoc wireless configuration

    Thanks to both of you for the responses. I have been planning to upgrade to
    a wireless router only after purchasing a new HDD and DDR RAM so I can
    upgrade to Vista on my Dell PC, but for the price indicated I will probably
    go for the router first.
