    Please note, I'm no expert in wireless networking.
    I have a main computer running XT that has a Siemens wireless router/high
    speed modem that is supplied by Bell, I have another computer in my kids
    room that is only about 10 feet away with a wireless card. The compute r in
    the kids room is plagued with sudden disconnects from the wireless internet,
    and frequently cannot even find the network. I have tried several wireless
    cards, both internal, and external USB, and have even tried external
    amplified antennas. Several months later, and about 100 calls to various
    tech support, still no connection.
    I recently acquired a HP laptop, that has a built-in wireless card, and it
    immediately connects to the network, without hesitation. I can be in the
    kids room or half way down the block, and it still works.
    So, considering the fact that I've tried many different types of wireless
    cards, both internal, external, using both the internal "slots" and external
    USB, would it be logical to assume that the problem must be in the kids
    computer????. If so, where should I look?
    Any help would be greatly appreciated

    Kids computer is XP as well, and whenever I run the diagnosis for whatever
    wireless card is in there, diagnosis says all is ok.

    I had a similar problem and I removed every last vestige of Zone Alarm
    even thogh it did not appear to be running and was not started in
    startup or anything.
    The problem went away and I cannot otherwise explain why Ii now have no
    trouble like that.

    In XP go to the control panel and turn off the firewall.

    A friend had a laptop (compaq, iitr) that simply did not work with a
    particular type of wireless USB dongle. Her son in the next room had a
    flawless wireless connection to the router, which was in her bedroom. The
    problem turned out to be that the laptop wasn't supplying enough power for
    the particular type of USB device. So, I suspect that WiFi requires lots
    of momentary power to transmit. Perhaps the computer's power supply is

    Is the router near your kitchen? Microwaves use the same frequencies to
    cook with. An old microwave might be interfering somehow. Also, 2.4G
    phones interfere with WiFi 802.11b. You may not notice it with the
    laptop simply by chance. Changing the configured channel might help.

    Since the room is only 10' away, one surefire way to fix it is to run some
    cat5 cable, and use Fast Ethernet.
