    I'm new to wireless having just got my 2.4ghz wireless G router set from
    Virginmedia. While waiting for it to arrive, I mentioned on a couple of
    forums that I had a 2.4ghz Logitech Pro 2800 cordless desktop set
    (keyboard and mouse), and was immediately inundated with people telling
    me to go straight out and "buy a wired mouse and keyboard", or "a
    cordless set that uses Bluetooth", as it would "definitely interfere
    with your new router". I asked if this was really necessary, as I really
    liked this desktop set and had spent a considerable amount of money on
    it, and I was told it was. Anyway, I listened to my instinct and played
    a wait and see approach. I'm glad I did, as I have now set up my
    wireless network, and the desktop set, sitting a just couple of feet
    away from the wireless router, has done nothing at all to interfere with
    my connection. So I Googled around on the subject, and found that people
    who have a stand-alone 2.4ghz keyboard or mouse usually run into
    problems with 2.4ghz routers, but so far I've not heard of anyone who
    bought a '2.4ghz desktop set' running into issues. As it mentions
    "pre-paired" in the specs of my cordless desktop literature, I'm left
    wondering if that has anything to do with it? Perhaps the keyboard,
    mouse and receiver don't do all the channel hopping that other 2.4ghz
    devices do as they're all paired up already?

    Yes, I know I should just be happy that I don't have to dump the best
    keyboard and mouse I've ever used, and that I should simply shut-up and
    enjoy my new wire free life.....but I'm just so curious as literally
    everyone told me that I wouldn't be able to get them to co-exist with my
    2.4ghz router. Are my above suspicions about them being "pre-paired"
    correct, do you think?

    I am using a Logitech wire less mouse and keyboard and so is my wife we
    have not had any problems with our wireless-- I am guessing you will not
    have any problem. In any event I sure would not go out a buy a wired
    keyboard/mouse until I saw a problem.

    But a lot of Logitech devices use 27mhz (usually the least expensive
    ranges) .....apparently it is only 2.4ghz devices that can cause you
    grief, as they're competing on the same frequencies as 2.4ghz routers. I
    believe 27mhz are the cheaper Logitech range, 2.4ghz the middle range
    and the ridiculously priced Bluetooth the higher range. I have a Pro
    2800 set and it is 2.4ghz....as is my new router.

    Oh fear not, if it stays like this I'll be keeping this keyboard and
    mouse. You'd have to pry it from my cold, dead fingers. I sent two other
    sets back until I found one I got on with. I do a lot of typing, so a
    good keyboard is important to me. :)

  4. Hi
    In general the 2.4GHz peripheral use another part of the 2.4GHz band and
    thus they do not interfere with Wireless Network component. Some off brand
    hardware that is badly made might.

    That's handy to know, thanks. I still find it odd that so many people
    warned me I'd struggle - perhaps their fears were based on earlier
    2.4ghz peripherals? I dug further into this - and I discovered that
    Logitech talk of 'Advanced 2.4ghz' in their product literature, and my
    set carries this unique 'Advanced 2.4ghz' logo. They talk of several
    similar pieces of equipment communicating in a small environment (such
    as an office) with no interference from one and other. They mean you
    could purchase several of the same model wireless desktop sets for use
    in an office, but each keyboard and mouse will ignore all but their own
    respective USB receiver. They say each receiver has a unique code, with
    no two identical codes ever leaving the factory. If they ignore other
    receivers, I'm presuming they'll ignore routers. See here:


    So there you have it.

    I hope this thread serves the archives well, and no one is duped into
    spending £100+ for a Bluetooth wireless desktop...as I came very close
    to paying it serious attention.

  6. Hi
    The issue is really the sloppy way that we communicate.
    Every one calls it 2.4GHz, I do not think that there is any device that
    uses 2.400000 GHz
    One device might use 2.41GHz the other 2.42GHz etc.
    It is like we would call all the houses on Downing street No. 10, ignoring
    that there is more than one house there.

    Yes, I've heard they caused nightmares. Luckily we have phones that use
    the DECT 6.0 protocol.

    Microwaves can make your connection a little giddy too, or so I'm told.
