I'm a road warrior that uses this Airport Express to create a small wireless network, protected of course, within my hotel room. I just plug the AE into the 110v desk plug and then plug the hotel's internet cable into it. Instantly lets me un-tether from the desk to the couch, the other room, the bed, you name it. I was waiting for the "n" speed and am quite happy with this device. It never leaves my computer bag except at the hotels.

The software that comes with new Airport Expresses is much more user friendly. You may find going through the instructions listed below is not required.

S. Monroe


The CD that comes with the Airport Express has been useless to me in setting up a Windows XP computer to work with an AE. The instructions below should get you up and running.

1. First download the latest version of both the Airport Update and Airport Express Firmware Updater from [...]

2. Run the latest version of the Airport Update (4.1 at the time of this writing)

3. Disable your firewalls, plug in the Airport Express (AX) to an electrical outlet and attach it to your computer or router with an ethernet cable. The AX will have a steady or blinking yellow light.

4. Launch the Airport Admin Utility...it should detect the Airport Express in the "Base Station Chooser" within a minute or so and the light on the AX should turn green. You may have to hard reset the unit a few times by pushing the small reset button with a paperclip for about 10 seconds. If, like mine, it does not show up in the Airport Admin Utility leave the AX attached by ethernet and reboot, launch the Airport Admin Utility, and hopefully it will show up quickly.

5. As soon as it does show up, launch the latest Airport Express Firmware Updater (I used 6.1.1) and update the AX...this seemed to make a significant difference in the ease of detection later. This will take a minute or so. The AX will reset and you may have to leave it attached by ethernet, reboot, and relaunch the Airport Admin Utility to detect it again.

I have a decent setup at home with a Apple Base Station (wireless N) and this Express which is used to extend my wireless connection to other areas of my house. Again all is wireless N.

The Express disconnects every so often and computers attached to it are unable to get any network access. It has to be unplugged and plugged back in to get the connectivity back.

The streaming of music is ofcourse awesome, however every 2-3 songs you have to remind your computer to use the express....why? Simply because the express loses its connectivity.

I took it to Apple and the Genius told me that its my network connectivity. I said ok..I would make sure I was close to my base station and test again.

I did....I plugged it in 10 feet from my basestation and connected a apple hi-fi for audio. Again...disconnects every few songs and we were back to the same thing again.

I have tried this with 3 different mac book pro's in our home and the results are similar. I am hopeful that the next firmware will fix things up but until then....this product gets 4 stars.

It does what it should...but not at 100% all of the time....just most of the time.

UPDATE 01/19/2009
The problems continue. I have tried over and over again to like this device. The constant disconnects and sub par performance really make me hate this thing...the only reason I keep it is for playing music.... Just wanted everyone updated.... Check out the D-Link DAP-1522 if you are looking to extend your wireless network.

UPDATE 02/06/2009
I have been advised, via comments, that I should change the channels on these devices. I did change the channels a number of times with no apparent FIX for the problem. Incidentally my brother has been having the same problems with his airport express. Next is to try to downgrade to the older firmware as one commenter suggested.

Let me start off by saying, that once we got all the bugs worked out, this is an awesome little piece of technology. But I must also say, that it took an entire week to get all the functions to work correctly between just two computers on our home network (my I-Mac and my wife's Vista based laptop). Apple claims this is a "plug and play" item like everything else they sell. And being a die-hard Mac supporter, I can say up to this point, that has always been true. Yet for those of us out there that are not familiar with setting up a Wi-Fi network, which Apple claims this product is for us, beware, you need to understand and know a lot about Wi-Fi, your cable internet (if that is what you have), and much more before you can get this thing to work. Even though most Mac's have the correct drivers (Airport Utility, etc.) already installed. Don't bother with them, install what comes on the disc supplied with your AE, this will save you about an hour of headaches. And for Vista users, don't bother with what is pre-installed or what is on the disc, download the latest version of Bonjour from the Apple website, this will save you days worth of troubleshooting on how to get the printer recognized by your PC. But, like I said, now that everything is running (haven't tried the Air Tunes because I don't care about that feature), it is like all Apple products, very, very, nice, compact, and smooth running. Apple needs to send out more detailed instructions with this product and provide better support, after all, we expect that type of service from them, not the "it doesn't work and takes forever to fix" type of service most of us have come to know and love from Microsoft.
