    If it is your wireless network speed that fluctuates, any number of wireless environment variables can be the cause.

     

    Your internet speed can vary as well. This is a function of your ISP.

    That is always an option.

    It is not possible to avoid wireless interference, any more than it is possible to avoid inhaling smoke in a cigar bar.

    That is the manifestation of wireless interference.

     

    You can a utility such as iStumbler to help identify competing wireless networks. It may help but it cannot exhaustively determine all sources of interference though.

     

    Use 5 GHz to the extent that your equipment supports it.

     

    You can always ask Apple to exchange your Extreme for another.

    A router physically can't avoid interference.

    The "firmware" wouldn't cause the problems you describe, if the firmware really was that bad why doesn't anyone else report these problems?

    If it *isn't* interference, then just swap it for another Extreme. You might have a faulty unit.

    If you're not a Mac user use inSSIDer to look for interference.

    5 GHz is very sensitive to intervening obstructions. As you approach the limits of its range dramatic bandwidth changes will occur.

    Avoidance is impossible. No router can avoid wireless interference, any more than you can avoid ambient noise. The analogy is appropriate.

    I know you don't have a Mac, so what device or utility are you using to determine that the speed fluctuates? Is it just one device, or several?

    which can be causing this horrible interference?

     

    What app are you using to determine throughput?

     

    For troubleshooting purposes, make absolutely certain you are using 5 GHz for your iOS devices - if you have not assigned a unique name to the Extreme's 5 GHz wireless network then do that. The Extreme creates both 2.4 GHz and 5 GHz networks simultaneously and you can't turn off just one, so the only way to be 100% certain you are using 5 GHz is to deny your iOS devices a connection to anything else.

     

    Bear in mind only iPads and the very latest iPhones and iPods support 5 GHz. Earlier ones are only capable of 2.4 GHz.

     

    Go to Settings > Network >Wi-Fi, tap any network other than your uniquely named 5 GHz network that may be listed, then "forget this network".
