    Interfere in what way? We're just about to start up the same.

    I can only get one or the other. The Network blocks out the camera.

    Not too surprising when both use the same frequency... Does the video have
    switches to change band? If not, there's not a lot you can do about it
    except change one or the other to different frequencies... You'll also find
    microwave ovens interfere too... :(

    i have changed to all 4 frequncies - no help

    What can i do, meaning what other solutions are out there?

    Typically, the video repeaters will wipe out the routers, but the routers
    will only cause noise to the video repeaters (popping sound and streak in
    the video at about 1 or 2 pps).

    The video repeaters (at least the ones I've seen) have a switch on each end
    that lets you pick one of four channels. If you try any of this stuff, try
    it first with the video set on the first channel, then the last. Avoid the
    channels in the middle.

    Some of the 802.11 stuff is spread spectrum, so it's constantly changing
    frequencies and doesn't put all of it's energy into one. Others, have a
    channel selection choice in their configuration. You'll have to play around
    with the setup on both the router and any wireless cards if you change any
    of the configurations. (THEY MUST MATCH EXACTLY.) If you're using a D-Link
    router & wireless card that have the "super-duper-speed-thing" turned on,
    turn it off. That'll make reception better regardless of any interference.

    Try to set the video repeater up first and make it as directional as
    possible. If it's the kind with the little panel antennas, try to point the
    sender at the receiver and vice-vera. If the sender has a little mast
    antenna in addition to the panel, fold it down, but make sure that you can
    still get a signal.

    If you're traversing floors inside a house with the router, but not the
    video (or vice-versa) consider putting one of the units on a high shelf and
    its complement on the floor. If you're only working in one plane, then it's
    just geography (not geometry <g>).

    Figure out if there's a place to put your wireless access point so that it's
    not directly in the path of the video repeater's signal. If it's a regular
    wireless router, like a D-Link or a Linksys, chances are that it has one or
    two little stubby antennas on the back. Unlike the video repeater antennas,
    these aren't directional; they are omni-directional so they're going to
    "spray" all over the place. You can prevent some of that, again, by
    pointing the antennas to where you need the signal and by trying to avoid
    overlapping with the video repeater's path. Again, depending on the type or
    routers you have, a good healthy reset (and configuration reload) wouldn't
    hurt every time you move something. I don't know it for fact, but have
    heard that some of the 802.11 stuff is "smart" enough to avoid interference,
    but may only look around when it's initialized.

    If this gets you anywhere close, there are some directional antennas that
    you can buy for the wireless routers that might help, but before I spent any
    money, I'd consider looking at the newer wireless stuff that's on 5.8Ghz. A
    whole new set of frequencies for everybody to muck up, but they'll be clean
    for a while. Also, you might look for some older video repeaters (?eBay?).
    IIRC, there were some that operated on 900Mhz and that shouldn't interfere.

    Finally, as you're playing around with the antennas, if you find that you
    can get the video signal lined up reasonably well, it does work to make a
    little shield out of any kind of metal (aluminum foil worked for me). Wrap
    this around the back of the panel antennas and let it stick out to protect
    the sides. (It probably should be grounded, but I didn't worry about it and
    it helped.) I never had to do it, but you could probably do the same thing
    on the router's antennas with foil and tape.
