Detailed information on Firmware Updates 7.6, including how to install the update here.


  1. Does it fix the issue where the Airport Extreme makes noise EVERY time you download anything wirelessly? It’s a well known design flaw I can’t believe a company as obsessive about silent operation would overlook.

    I consider myself a fervent Apple fan, but the Airport Extreme (latest gen) is a noisy POS. Easy to configure though.

      1. An annoying scratching noise, that would happen only when it downloaded anything over wifi. AEBS unit was a new and latest gen bought from Amazon.

        Found it incredibly annoying since im always in the same room as my router. God, now everyone who hadn’t noticed it will now hate it.

        1. A WiFi router should be completely silent in operation. Ensure that the source of the noise is the Airport Extreme. If it’s making a noise, something’s broken. I can’t imagine what it is because the AEBS has no moving parts inside.

        2. As Redd Foxx would say….”Xactly”.
          Maybe if an external drive were hooked to it
          but it sounds like someone busted a cap in that mutha
          (OK, a leaky capacitor in geek-rap)

        3. I quickly isolated the noise as coming from the AEBS unit. Not a Time Capsule with an enclosed hard drive, but an Airport Extreme (Fifth Generation).

          I quickly noticed the scratching/buzzing sound from the AEBS instantly in every time I browsed or downloaded ANYTHING over WiFi.

          you get the idea

          I had no choice but to revert back to my trusty and silent WRT54GS from 2004 until the AEBS’s replacement, the e4200 arrived.

  2. I updated 4 yr old extreme and 2 expresses that extend my network in about 60 seconds using the new Airport utility on my iPad. It’s another bit of Apple Magic. Just amazing to watch!
