Assigning IP's from Airport Express to specifici MAC addresses/Computers

I have two AX, one is host, other connected via WDS.
Behind that is my MacBook, on which runs a nifty AJAX based remote that is accessible from my iPhone.
I can choose to enter a local IP, or with port forwarding enabled, even the WAN IP on the proper port channel gives me access.
The only real problem is that the IP address (10.0.1.X) of the MacBook being controlled seems to change from time to time, making it rather pointless to bookmark the URLs of the AJAX remote. So.... is there a way to make it that when my Macbook (uniquely identified by MAC address I'm assuming) joins the network, it's given a specific IP address, one that can remain in my bookmarks so as to be used on a whim, without updating and preparation?

For those of us that can't afford a brand new router just for one little feature, here's a workaround.
Get rid of DHCP.
Set all of your Macs' IP addresses manually.
This isn't as taxing as it sounds...
Go into *System Prefs*, and *Network Settings*. Double click on Airport, then open the TCP/IP tab. There you will see the following settings:
Configure: Using DHCP
IP Address: 192.168.1.3
Subnet Mask: 255.255.255.0
Router: 192.168.1.1
These might not be the exact numbers you see, but remember/write down what you do see.
Change "Using DHCP" to "Manually" using the drop down menu.
Hopefully all the settings such as Subnet Mask and Router will be the same as they were before, you will be left with 0.0.0.0 in the IP Address Box. This is the address for your computer. Enter in an address similar to the one you had before, but perhaps add 5 or 10 spaces on the end... So for example 192.168.1.10 .
If the other values haven't automatically copied across, enter them exactly as they appeared before.
Finally, you need DNS Addresses. These can be found in your Airport Admin Utility under the "Internet" tab - but every single one I've ever set up seems to default to
194.168.8.100
194.168.4.100
Try them, if you can't connect to the internet, check your admin utility under Internet settings and copy those DNS Server addresses across.
I hope that makes sense, if not please leave a response!

Airport Express WiFi network MAC address filtering not working

I have an Airport Express WiFi network which I bought and installed new in 2011. Initially I enabled MAC address access control and populated a list. It was working perfectly, I know, because a niece visiting tried to connect her iPhone and could not until I added its MAC address to the allowed list. Now however, anyone can connect without being added to the list. I think I read somewhere that a recent firmware update permanently disabled MAC filtering in Airport Express, even when it was previously working? Can anyone enlighten me about what's going on here?

In a sense those are/were/should operate as two separate functions, which they did before recently.
They do operate as two separate functions.....but it all depends on how you have the default rule setup in Timed Access.
If the default rule in Timed Access is set to No Access.......then a wireless device cannot connect....even it has the password for the network.....unless it has been setup on the list of allowed devices in Timed Access.
I have checked this 3 times this evening to verify. It works as it always has, and as expected.
If the default rule in Timed Access is set to Unlimited, then any device can connect to the network if it has the password. Devices that are listed or specified in Timed Access will be allowed to connect at the specific times that have been set up for each device.
So, if you want to use the more traditional MAC Access Control settings, the default rule has to be set to No Access and then you must set up a rule for each device that you want to allow to connect to the network. Only devices on the Timed Access list will be allowed to connect to the network. Other devices will not be able to connect to the network....even if they have the correct password.
If a recent firmware update has changed things from what they have always been.....then I am not affected....and I should be if I am using the same firmware as others.

Can I assign Airport Express to static IP Address?

Current setup - Airport Extreme attached to cable modem with 2 hard drives, Airport Express as print server in separate room with USB printer attached (just changed from Linksys with sometimes working NetGear print server). Clients accessing the network: 2 Windows XP, 1 Windows 7, iPads, iPhones, iPods, Apple TV, and sometimes a Mac Book.
The issue is that we don't keep the printing system on at all times (light switch with Express and printer plugged in); We dont't do much printing, and I print to pdf most of the time. As a result, the Express IP address changes every time it's turned on, requiring me to change the port settings on the printer properties before anyone can print. Is there a way to assign a static IP address to the Express so that I don't become tech support every time someone else in the house needs to print something?

Is there a way to assign a static IP address to the Express so that I don't become tech support every time someone else in the house needs to print something?
Yes. The first order of business is to find the AirPort ID for the AirPort Express. You do this by opening AirPort Utility and clicking once on the Express. In the area to the right, jot down the AirPort ID.
Still in AirPort Utility, now click on the AirPort Extreme and click Manual Setup
Click the Internet icon
Click the DHCP tab below the Advanced icon
Look for the DHCP Reservations area and click on the + (plus) button at the bottom
Enter a description, for example AirPort Express
Click the MAC Address button and click Continue
Enter the AirPort ID in the MAC Address box
Assign the IP address you want the Express to use, for example 10.0.1.20
Click Done, then click Apply and the AirPort Extreme will restart
It would be a good idea to power cycle the entire network as follows:
Power everything down...all devices, order is not important
Power up the modem first, then AirPort Extreme, then Express, then devices

Clicking sound originating from Airport Express firmware 7.5.2 and later

Hello,
I have submitted a bug report through Apple Developer Connection (I am a registered developer). By posting this here I want to get support for our case: Make Apple fix the Airport Express firmware.
Summary:
The Airport Express device has a bug which appeared first in version 7.5.2. It produces a "clicking" sound when using AirPlay to transport music from an iPhone or a Mac, when certain frequencies are being played. This is not depending on the attached amplifier or headphones, digital or analog output, network settings (network created by Airport Express or not), Mac or iPhone used, audio cable or power supply involved or due to bad quality of the sound file played. The problems are not there when audio is played directly from a Mac or an iPhone through headphones or optical out. We and my colleagues (developers and audophiles) have ruled out all the other options. The problem boils down to a change in the Airports firmware starting with 7.5.2. In 7.4.2 the clicking sound is not there.
Steps to Reproduce:
Play the following song via AirPlay on an Airport Express device having firmware 7.5.2 or higher. The Airport Express being used in our tests is the model produced from March 2008 – June 2012. Attach high fidelity headphones (like Bowers & Wilkins P5, which we used) to Airport Express. Alternatively use a very good amplifier/loundspeaker setup. We also reproduced the bug for example on an Onkyo A-9070 amplifier with both optical and analog connection - there is no difference there. The loudspeakers we used are passive Dynaudio X12.
Play track no. 6 from the "Songs without words" album: http://itunes.apple.com/de/album/lieder-ohne-worte-op.-67-no.-2/id209380163?i=20 9381206
Listen to this solo piano piece carefully for at least 40 seconds. You will notice a clicking sound with high frequencies. This clicking is *not* there in firmwares 7.4.2 and earlier.
Expected Results:
Perfect audio quality as in firmware 7.4.2 and earlier.
Actual Results:
Reproducible clicking sounds in high frequencies.
Regression:
This problem appeared first in Airport Express firmware 7.5.2 and has not been fixed yet. It can also be observed in the current version of Apple TV (as of September 16th).
Notes:
This issue, while not being recognized by the casual listener, makes AirPlay unusable for critical listening - at least when using any firmware after 7.4.2. I would love to use the current firmware (which produces a much more stable connection), but I (and other audiophile AIrplay users) would love to see this issue fixed first.
Here is a thread that concludes - as we did - that Airport firmware 7.5.2 and later is the source of the problem. It is not the hardware, neither Apple's, nor the connected devices:
https://discussions.apple.com/message/17296916#17296916
Hope this helps!

I'm having the exact same problem. As a classical music lover, this is driving me nuts. It's especially noticable in soft passages in the music, when the volume is turned up high. When the dynamics increase, the little pops/clicks appear (they sound a bit like static noise, as someone stated earlier in this thread). It happens at irregular intervals. When you play pop music, the clicks will disappear (drown) in the music. But for true audiophiles who listen mainly to jazz and classical music this is a severe problem.
I have checked everything and it's definitely an airplay issue. My apple lossless files are 100% okay and play without any problem, except when streamed via airplay. Also, it makes no difference whether you use the analogue or the optical ouptut from the airport express.
I've created a sine frequency sweep myself in Adobe Audition, from 20 Hz up to 20000 Hz with a duration of 25 seconds and a level of -6 dB.
When played through airplay, the clicks always start to appear after 4 seconds in the sweep, only to disappear at 23 seconds.
The clicks manifest themselves at different volume levels. To my ears, they make the same sound as when you change the volume in iTunes when streaming music through airplay. Only when you set the volume in iTunes extremely low, the clicks will disappear.
Apple engineers should use a frequency sweep to recreate the problem, as this is very revealing.
PS: file format isn't an issue here. I've converted the Apple Lossless file to MP3, and it makes no difference at all.

I cant go on youtube with the wifi from airport express, its alway show that the webpage not found so I try to connect the lan to my mac ,its work. Anyone know why amd how to fix it. (only youtube and google doesnt work)

Is this an airport express problem?? Only Youtube and google doesnt work. Its not work only on wifi from airport express. I really have no idea about technical problem.

After the last upgrade, my itunes doesn't open (this happen only the first time after the start of my pc). It seems frozen.To re-open Itunes i need to terminate APS deamon every time from task manager.
What is Apple doing to solve this problema? Thank you.

How to print from airport express?

I bought HP deskjet F2100 printer and i tried to plug into my airport express for printing and from my acer laptop(WinXP) i could setup according to the manuals of airport express and i could make wireless prit but when i tried to print from my macbook(OS X 10.4) i couldnt print even though i follow the manual book from airport express, i get "unable to connect to printer". i could see that HP Deskjet F2100 in my printer setup utility and i could see in the box browser- HP DeskjetF2100 and in connection is bonjour, but still i couldnt print.I have airport express software in both of my laptop and from acer i could print wirelessly but from macbook i couldnt. And in both laptop i could connect internet wirelessly but i couldnt print wirelessly. i dont understand how come both apple product macbook and airport express are not compatible..
i would be very thankful if someone could help me............

The HP Mac drivers are incompatible with wireless printing.
Use the process outlined here:

Do I need to have Airport Express to connect to other computers on our homer network?

Do I need to have Airport Express to connect to other computers on our homer network?

Not necessarily. You could use the "Create Network" feature of your MBP's built-in AirPort card to provide an Ad-hoc wireless network for local wireless-capable computers to connect to.

I installed an airport express, on my mac book i can use the airplay using iTunes, but on my iPhone en ipad the icon for airplay not appears on the screan when i start the music player.

Chances are, you have already tried this and already know the answer.
But, if not....sorry, but no......since your printer is not AirPrint compatible, you must use the extra software workaround in the Mac.
A newer AirPrint printer would allow you to do what you want.

I am upgrading wi-fi router from Airport Express to Airport Extreme. I followed set up instructions yet I am still getting the flashing amber light and cannot setup (using manual setup or the continue button). What should I do??

Hello,
I am upgrading my wireless router from an Airport Express to an Airport Extreme. After disconnecting the Express and plugging the Extreme via ethernet cable to the modem, I am receiving a flashing amber light after connecting the power source. I also reset the modem while the Extreme was still powered and plugged into the modem, but no luck. I also tried resetting the modem and the Extreme and still no resolution. Please advise. Thank you!

This error usually occurs when the Windows Firewall and/or anti-virus software blocks the connection attempt from the PC to the AirPort Extreme.
Microsoft Security Essentials can do the same thing.
Things would be much easier if you had a Mac or iPhone or iPad to set up the AirPort Extreme. Otherwise try turning off the Windows Firewall and Anti-Virus programs, etc on the PC.
Restart the PC, then see if the PC can contact the AiPort Extreme. It will likely help to connect an Ethernet cable from the PC to one of the LAN <-> ports on the AirPort Extreme. You can disconnect the Ethernet cable once the AirPort Extreme has been configured.
Re-enable the Windows Firewall, Anti-Virus, etc and restart the PC.

Cannot print or scan with USB printer over wifi from airport express / time capsule wifi

Hi everybody,
I have recently set up time capsule connected to the router from the telephone company but created a new wifi network for the time machine to better work. Now I have bought an airport express to be able to use my USB printer over the WIFI network. I have to laptops, the printing works fine over the mac book air but not over the macbook pro. On top of that I cannot scan with either of the devices.
I have scanned most of the information out there but this issue seems not to be addressed properly anywhere. Advices given do always repeat itself but no solution worked for me.
Now I have plugged the usb from the printer directly back into mac book pro and the problem seems to persist here too. The message I receive everywhere is this one:
The software for the printer was installed incorrectly.
Would you like it to be repaired?
When I hit the Repair button a notice says 'repairing permissions' but nothing really happens. In the end nothing has been printed.
Resetting the printing systems has not really changed anything either. The problems persist.
This is the screen I get when the printer is directly plugged in through USB:
Result: printer recognised and installed, I cannot print (The software for the printer was installed incorrectly), but I can scan (probably because of the hint ('multifunction')
When I try to install the printer through the network connection (wifi network over time capsule and airport express) I get this image:
Result: printer recognised over bonjour but without multifunction (in other words without scanning), I cannot scan nor print (The software for the printer was installed incorrectly)
As I already mentioned any solution I found online would not work. Now the qustions are:
1) why can't I print? The drivers seem to be there but somehow broken, and I don't know how to repair it
2) why can't I scan over wifi? It sould possible that any function that can be performed over cable should also be able to performable over air, right?
I would very much appreciate any kind of help.
Thank you in advance,
Cris

What's up doc?
HP has not provided "network" drivers to allow advanced features when the the All-in-One is connected to the USB port on the Time Capsule.
Therefore, only the printing function is supported when the All-in-One is connected to the Time Capsule's USB port.
If you need advanced features like fax, copy, scan, maintenance etc., you will need to connect over the WiFI network, or connect the All-in-One directly to your computer.

Limit Audio Output from AirPort Express

I have active loudspeakers (B&O) that I'd like to drive with the airport express station. As I can not adjust the volume of the loudspeakers, I'd like to know, whether there is a possibility to regulate the output of the audio signal within the express station, rather then iTunes. Why?
a) I have connected my loudspeakers to express and it worked all too well, at 24:00h, my neighbors where really happy, as all 70 watts started.
b) the volume control of iTunes is not good enough to really control the output (its nearly zero or full power).
c) I want to be flexible with my macbook and not necessarily sitting at my desk.

Hi TD,
What I've done with my similar set up like yours is that I've added on a Grace Design m902 unit in between the Airport Express and the active speakers. The Grace unit also comes with an optional remote control which then allows me to adjust the levels without having to touch iTunes.
You can have a look at the unit HERE..
Otherwise, you can look at other cheaper pre-amp alternatives. The reason I liked the Grace Design unit is that it allows me to also send a USB out direct into the unit from my computer if needed. Good luck!!

Fuzzy music from Airport Express

My Airport Express streams music from itunes to my sony home theatre but the music quality is terrible. The music is distorted and I can't for the life of me figure out how to fix that. Any suggestions? Is it maybe a network tweak? My router/modem is a Motorola surfboard if that makes a difference, but let's stray from suggesting buying a apple router.

I suggest that you first try connecting a pair of stereo headphones to the AirPort Express Base Station's (AX) audio port and see if the distortion continues. Assuming that it does, it is very possible that you may have some form of Wi-Fi interference in the immediate area that is preventing your AX from getting a good clean signal from the audio source.
I suggest you perform a simple site survey, using utilities like MacStumbler or iStumbler to determine potential areas of interference, and then, try to either eliminate or significantly reduce them where possible.

Stuttering audio from airport express...

I installed my first airport express yesterday. Had some problems: my main computer couldn't load the Airport Utility (see http://discussions.apple.com/thread.jspa?messageID=7132922&tstart=0), and I've gotten things configured through another computer but I'm getting lots of stuttering audio when I attempt playback.
There's a pattern to it: the song starts fine, and then about 3 seconds in it starts stuttering. A buffering issue?
No problems on the network that I'm aware of.
I tried setting Quicktime to "safe mode waveout", but no help.
Any tips?

Typically, "stuttering" can be a result of either low signal strength or high signal noise values, or both.

Horrible Audio Quality from Airport Express

Last night, I purchased an Airport Express for the sole purpose of using it as a client on my already exsiting 802.11g wireless network to play my iTunes on my living room stero. It took me a while to get the configuration set up correctly, but I finally have it so that it is communicating with the network and sending information and iTunes to the AirPort.
My problem is that the audio quality on my stero system is horrendous (i.e. unlistenable). It sounds like I'm listening to a radio broadcast from way out of range.
Here's the odd part - the connector cable to my stereo works fine with other audio devices (i.e. my iPod) - and the Airport Express works fine with just my headphones. So, there is no problem hooking into the stereo and no problem with range or communication between my iTunes, network and the Airport.
I think this issue problably has something to do with the levels from the Airport unit into my stereo, but I don't know exactly what my next move should be. The only thing I'm quite convinced about is there must be a very simple answer to this problem which has had me pulling my hair out for hours now.
If anyone could suggest something that could help, it would be much appreciated. Thanks in advance.

Hi cozmocramernyc,
I am glad it works.
I use the Digital Optical cable instead the standard cable and the audio is Awesome.

How to get internet connection from Airport Express to a PC?

I recently bought an Airport Express to get internet connection from my new MAC COMPUTER TO ANOTHER PC which is located in another room. For unknown reason, I could not get the other PC to work. Any idea how to fix it so that I can get internet connection for my PC? Many thanks for your expert assistance.

Currently, the Airport Express (not the Airport Express Extreme router) is acting as a base station via Ethernet to a cable modem.
I guess that it would be correct to assume that your new Mac can connect wirelessly to the AirPort Express base station, and access the Internet that way.
I am not sure if my 41/2 year old HP(Hewlect Packard) PC - (with AMD Athlon 64 3400 processor) which I am unable to get internet connection now is Wi-Fi capable.
You said "Prior to using the new Airport Express,I was using the Linksys wireless G router and have a wireless adapter sitting on top of my PC.". The wireless adapter would be Wi-Fi certified (they normally are). Is it a USB adapter? Please post back with the exact model.
Question: do I still need to use the adapter or not? Or the new Airport Express is enough to send internet signal to the PC?
A Wi-Fi adapter would act as a wireless network card for a PC, and should communicate wirelessly with an AirPort Express base station without a problem (providing that the chosen security/encryption is supported on both sides). Since the wireless adapter apparently was OK (with the Linksys router), you should be able to continue using it. Any other (built-in) wireless capability ought to be externally visible at the PC as a PCI card with an antenna.
Does the (Windows?) PC operating system detect any wireless networks? Is your AirPort Express on this list (even if you cannot connect or access the Internet)?
