I found the same problem, which my airport express status light is green but Airport Utility can not see it. Also, I cannot print or stream any music.
However, I followed Bob's instruction to turn off and on again. I works but then the same problem comes back again.
So, I downloaded and installed the Airport utility 5.6 for OS X Lion. This works. Unlike Airport Utility v6.0, the version 5.6 can see the airport express (which cannot be seen by v.6).
However, I still cannot print and stream music via my Mac Book Pro or my iPhone. Please let me know how to fix the airport express problem.
By the way, my Airport express is A1264 but it has problem with Airport utility v.6.
It's appear on the Airport Utility V.6 for a period of time. Then, for a while, it cannot be found by Airport Utility v.6 event the status light is green.
However, it can be found by the Airport Utility v.5.6. But the key issues are that I cannot print and stream music wirelessly using the Airport Express. Any suggestion?
I'm having the same issue with a different twist...
Just bought a Time Machine to replace my router....and now my Airport Express is no longer showing up in Airport Utility.
Also, the speed is awful. I have 25MB coming into the house via ethernet....but a speedtest on my wireless network shows me running at 4.5Mb download speed.
I spent $500 on the Time Machine. I don't understand it.
thanks for the great reply and link. you had probably done so while lion and not mountain lion was out. now, with mountain lion, the 5.6 version is not supported by the new 10.8 os.
sometimes mac goes just a little too far when it comes to its ol' 'out with the old' policy. just sometimes.
if i find a piece of software that supports mountain lion and airport express, i'll post a link.
ah! we have an excellent savior. give him some cash if you've got it and appreciate it.
WILL allow 10.8 to install the 'old' airport utility 5.6.1 and run to set-up your b/g airport express. follow his instructions to the T. they are esy but unorthidox.
Hello All: I visited my mom this weekend and at some point I had issues with her router... I am running Lion with v6.2 Airport Utility. I too ran into this problem of the airport express 802.11g--and yes I was a little saddened to see that Apple did not include this older model into its update. First download the older Airport Utility v5.6 http://support.apple.com/kb/DL1482?viewlocale=en_US 2 Next download this free too to upack the dmg file http://www.macupdate.com/app/mac/16357/unpkg 3 Now you can use the upack tool to open the dmg by dragging and dropping. After the tool opens it I found a folder labeled AirPortUtility56 on my desktop. Drag that into your applications folder. Open the folder and launch Airport Utility 5.6 it worked. I was able to setup the older airport using my Macbook Air. I copied this folder into my mom's MacBook and put it into her applications folder for, well future need. This was the original source that I found but wanted to make sure this was archived here as well: http://www.macworld.com/article/1167965/mountain_lion_and_the_ancient_airport_ba se_station.html
I've had this problem on an ad-hoc basis from time to time when installing Airport WiFi networks in Hong Kong. It is frustrating and I really havent been able to put my finger on what the problem is, I do however do the following and it seems to resolve itself..
I quit Airport Utility (v 6.2 620.33)
I then turn WiFi off
I then turn WiFi on
I restart Airport Utility
From what I can figure, and please correct me if I'm wrong is the following.
Airport Utility is constantly polling the devices to make sure they are operational and thus providing any alterts (you can set Airport Utilities up to alert you if there is a problem) to you if something untoward happens.
Airport Utility not seeing a device or having it greyed out on it's console screen doesn't mean there is anything actually wrong with the device. I've had many instances where the WiFi network with multiple AE's and AEx's are on are all operating and downlaoding / streaming but they are either shaded out or have the warning orange light and an exclamation mark against them.
As Airport Utility is constantly polling the device there may be some interference from either an environmental issue or from co-channel interference (most problematic in the 2.4 GHz range). Noise or interference in the 2.4 GHz range could trip the parameters for QoS that the Airport Utility uses. I'm only guessing though.
You may also want to look at what network you are using to view Airport Utility via. It may sound stupid, but if you're using or are connected via a 5 GHz only network or visa versa with a 2.4 GHz network connection and you all of a sudden are out of range of the 5.0 GHz or 2.4 Ghz whilst using the other..... once again polling comes into play.
In short, I give it a kick in the bum and then it seems to play nice, until the next time and then its bum kicking time again.

I also thought I would try restoring a previous version of Airport Utility from my Time Machine Backup only to be told it was imposible since Airport Utility is reguired by OSX.
Thanks for this...
When I get time, I will try downloading an older version.
My wireless works, but I can no longer configure it with Airport Utility.
