I have an Airport Extreme and twi Airport Express installed in one network. Then I changed the password to join the network and both Airport Express unit were disconnected. Now I try to reinstall them into the network with Airport Utility, but the both Airport Express unit are not visible in the left side of the utility widow. Meantime the Express units show a flickering yellow light. Thanks for any suggestion to solve this.

MacBook 13", Mac OS X (10.6.2)

    I'd connect each Express unit to your MacBook (one at a time) with an Ethernet cable until you can complete the configuration process.

    Did you also change the network passwords of the Express units?

    No, I did not change anything on the Express units. Everything was well installed and working together fine until I changed the Extreme unit password by accident, and the wireless access password at the Airport Extreme (Base unit). Reason to do this was to define a new wireless network password to exclude a too demanding gaming client . Now I am stuck with two Express units in other parts of my home that lost connection with the Base station and are not visible in the Airport Utiity anymore. Thanks for any pointer to solve this.

    I can't be sure that this is a requirement, but I would expect the Express units for connect better if their network passwords matched that of the Extreme.

    Thanks for any pointer to solve this.


    As I suggested, connect your Mac to each of them in turn with an Ethernet cable until you can reconfigure them.

    Oh my oh my

    What is going on with Airport Utility? Is it the iPad update that has left us all in the dust? I cannot configure ANY of my base stations. Everything from cannot be found when it scans to cannot find ppoe host to saying "invalid password" just after I reset and put the new password in.

    My only internet access is through a shared internet connect, hardwired with ethernet from the modem to the iMac. The iPhone can find this, but NOT the G4.

    Please, Apple Gurus, help! I have been an Apple owner and user since 1986 and I have NEVER had problems like this. Molto frustrating - have been at this for hours.

    I am running into a similar issue. Airport Utility is randomly seeing an Airport Express 802.11N 5Ghz, a Time Capsule 802.11N 5Ghz & 2.Ghz, and an old Express set up just to do AirTunes. The Airport Utility will randomly see and then loose each device when I am wireless. I'm don't have any issues with internet or NAS connections and the airports appear to be doing what they should. It just seems like an issue with the Airport Utility.

    Hey Guys, I have this very issue on my vista os. Everything was, and is still, working fine in terms of equipment and hardware. The ONLY CHANGE made was to the network NAME and PASSWORD (I have a 500gb tc, single band & a dual band base station). Each base station has the same, updated, password. They had the same password before this issue started.

    On my mac os, because of the network name change, I had to give my password EVERY TIME I connected to my base stations via airport utility. I would click on "remember this in my keychain" every time I saw the chance. Password never kept. After playing patty-cake with it for a second day, I managed to fix it. (I turned OFF the password protection security feature on both base stations, at the same time, restart, then added them back, restart, ta da!!)

    Not so much with the vista os. I cannot even SEE them on airport utility. I CAN access them via "configure other" on my local network (10.0.1.1 + password). This "access" lasts from about 30-90 seconds or so before the window itself "freezes" and I can no longer manipulate anything in the base station window. My only option being to close the window, then a prompt shows "are you sure you wish to close window, any changes will discarded." Sadly, all of this is moot because it will not let me restart the base station to update any changes. It simply ignores any command requesting restart.

    By the way, plugging the base stations in directly to the computer via Ethernet cable, does not work, in this instance.

    I am tapped for ideas, but did want to add my 2 cents.

    I've had a similar problem. I cleaned my carpets yesterday and had to switch off my Airport Express, which has been continuously running for 18 months with no problems. When I switched it back on however, I just cannot get it to work (nothing has changed). I have a number of devices that connect and only some will reconnect.
    * iMac - connects like a dream
    * MiniMac - network not even visible
    * MBP - most of the time network not visible, did manage to get it connected a couple of times through restarts and connected with full bars when it did
    * iPhone - connects like a dream
    * *HP wireless printer* - network not visible

    I've spent hours on this and nothing seems to change the above. Is it possible that a software update has taken affect when my AE restarted and has caused all these issues? I can't think what else it could be. I've had a look using iStumber and nothing else is on the same channel and the signal looks ok. Just about to try a hard reset of the AE.

    I managed to get mine working. I switch everything off, including all the devices connected to the network.
    Then switch everything back on, starting with the ADSL modem, then airport express, then devices and it all work. Previously I only switch off the ADSL router and the airport express.

    I managed to get my Airport Express units working again by using the rest button and reconfigure the device. Thanks for your help and comments.
  • James1973 Level 1 Level 1 (0 points)
    My fix turned out to be temporary but I seem to have it working now. I disabled the auto channel on the airport express and selected manually selected a channel not used in my area using iStumber and it worked. Its been running for 24 hours now with out any issues.
