    Model F5D8230. Anyone else have a problem with the wireless signal
    varying in strength? Nothing to do with walls in the way - happens when
    laptop is sitting right next to the router.
    Thanks,
    Tim

    What wifi are you using in the laptop?

    My setup was fine until I bought a new laptop! - the new laptop has standard
    802.11g inside it (the old ones have the belkin pre-n pcmcia cards), and I'm
    wondering if, for some silly reason, the router has a problem with the
    mix... It does seem to go away when I turn off the inbuilt wireless and use
    a pre-n card instead.

    unfortunately, mixed into this I have updated the routers firmware and toyed
    with BurstACK amongst other settings, so I'm not too sure.

    I encountered a similar condition, though not with rx and tx side by
    side, with a Belkin wireless access point, F5D7130UK connected to a
    single port router (voyager 205) using BT Broadband. Signal strength
    varied from -50db to -65db during the day and -60db to -75db during
    the evening, monitored on a Belkin PC Network card by Belkin's
    Wireless Configuration Utility - Link Status option.

    I changed ISP and the router exhibited a disconnection problem. After
    much pd on the disconnects, and in desperation, I purchased a Netgear
    DG834G wireless router. That fixed the disconnects, and made the
    Belkin access point redundant. The rx signal from the Netgear varies
    less. It is currently, varying from -42db to -46db. The router is in
    *exactly* the same position as the Belkin Access point was, and the PC
    is in the same location.

    I wish I knew how to measure the tx power on these two bits of kit
    because one of them has a problem!

    Thanks
    The laptop has 802.11g but I don't think that's the problem - the
    router was bundled with a PCI adaptor (now in my son's PC) and that has
    the same problem (without trying to use the laptop at the same time).

    The thing you have to remember with WiFi is that it uses the unlicensed
    2.4GHz band - so basically any piece of kit can use that spectrum, without
    regard to what interference it causes to other users of the band. So,
    Bluetooth, WiFi, wireless video cameras, microwave ovens and other
    "Industrial, Scientific and Medical" users are in that space, and may be
    the cause of what you describe. You could try changing channels, or using
    directional antennae to eliminate interference.

    The thing you have to remember with WiFi is that it uses the unlicensed
    DECT telephones too IIRC... although with pre-n mimo technology, this
    *shouldn't* be a problem - its always operating on two channels and actively
    searches out the best ones available.

    Nope, DECT is a different band. If your DECT phones affect your Wifi, you
    have faulty kit.

    DECT telephones too IIRC... although with pre-n mimo technology, this
    Fair enough, but my point about pre-n still stands... also, a quick google
    shows that one can get cordless phones that operate on the 2.4Ghz band
    (albeit not DECT standard)

  9. primarily in the US I suspect, where they don't have DECT

    Which was? Something that uses a different frequency band shouldn't affect
    pre-N wifi?
    Type-approved for use in the UK? Doubtful.

    The point is still at the top of this message

    But DECT phones don't use 2.4ghz, so it's not relevant.

    The point isn't relevant to DECT phones, but it IS relevant to interference
    from other RF sources.
