Airport Express - IP configuration issue

I am running a Sky router (made by NetGear) connected to an Airport Express base station via Ethernet (which also runs into my amp with iTunes) and have a second Airport Express base station for connecting to my printer in a separate room. The router is set up as a DHCP Server but with the wireless network turned off as I want to use my Airports. I have a home network with a number of devices connected either by Ethernet as well, including a PC running Windows XP.
I occasionally get an error message on a number of the of the devices "IP Configuration - 192.168.0.2 in use by XX:XX:XX:XX:XX:XX, DHCP Server 192.168.0.1", but I can still access the internet after I click on the OK button. I can't work out what I have to change and where (router or Airport Express) to get rid of this - can anyone help? Both Airports are set up in wireless mode "Participate in a wireless network" and Connection Sharing "Off (Bridge Mode)" and Configure IPv4 "Using DHCP".

Is this what you're seeing: http://support.apple.com/kb/TA20452
You appear to have configured your Expresses correctly so they're not to blame.

Check those wired clients to be sure they're not occupying that address. Configure them to receive IP addresses via DHCP.
It's possible your router needs to be reset. Resetting routers can be as simple as power cycling them, although sometimes you have to leave them powered down for the better part of an hour. In some cases there is an internal battery that must be removed.

AirPort Express setup/configuration issues with FiOS

I just spent the last 6 hours trying to set up AirPort Express so I can play itunes wirelessly on my stereo system. I came across several issues—some that i overcame and others that i will certainly lose sleep over tonight. I started by connecting the AE to a LAN port on Verizon FiOS wireless router using an ethernet cable, then plugged AE into an outlet (i assume this is the only way AE can get a signal). I then went through the entire configuration process and got to the last screen which said something to the effect of "the settings have been successfully updated. you can close this window or wait for the AE to restart". after a few minutes of seeing "waiting for AE to restart", it timed out and i got an error message: an error occurred while reading the configuration, blah blah blah. the error was -6753, if that's any help. all night i've been resetting the AE with a paper clip and trying it over and over again to no avail. i'm pretty mac fluent, so this has been incredibly frustrating. any advice from anyone would be greatly appreciated. thank you!!

Not a network guru by any means, but do have some experience with AEs. Try connecting an ethernet cable from the AE directly to your mac to make the initial setup using the Airport Utility (double click the AE in the list to open the configuration; set the settings in each tab). Once your done, 'update' the settings and wait for the AE to show up again in your AE Setup assistant. Now you can unplug from mac and plug into your router.
As far as settings go. You can either 1) 'join a wireless network' (use existing login/pass from wireless network; no cables required), OR you can connect AE to router via ethernet and 2) 'create a wireless network' (and use this new wifi network for all communication including Airplay) or 3) wireless mode 'off' (only use AE for Airplay connected through the wired network). Lot of options.

Should airport express be configured with the same network as my existing router

Should airport express be configured with the same network name as my Verizon router.

A router signal can not be boosted as all routers put out the maximum allowed by law. However, proper placement of a secondary router will enable it to "repeat" or extend the signal.
An Airport can "extend" the WiFi created by another Airport. It can not extend a non-Apple WiFi. You need TWO Airport units, one to function as the main radio and the other to function as an extender. I used two Express units.
Configuration is simple if you start from a factory default condition. Connect the main Airport to AC power and finally to the Internet modem (or modem/router). Open Airport Utility on your Mac or other computer and accept all of the recommendations. After confirming that it works, insert your desired administrative and WiFi passwords.
Then connect the extender to AC power. As before, open Airport Utility on your Mac or other computer and accept all of the recommendations. No need to add password info.
Do not expect the Airport to respond instantly to the configuration commands. BE PATIENT!

XP machine can only connect to Airport Express through Configure Other...

I have an Airport Express running the latest firmware (6.3). It works fine with my Mac, however I can't get it to work correctly with my XP machine. It's setup to just do music and not give out IPs. I've tried connecting it to my router via wired and wireless and doesn't work either way. I can connect to it if I go to Configure Other... and type in the IP but I can't see it in the AirPort Utility scan and I can't see it in iTunes.
A possibly related issue is that I can't see my Mac's shared iTunes library on the XP machine but I CAN see the XP machine's library on the Mac.
Everything is on the same 192.168.0.x subnet.

Just can't get Airport Express to configure: it worked at my mum's, but not at home!

Hello helpful people,
I am really hoping someone can think of what's going wrong with my set up. I keep getting an error message "an unexpected error occurred, please try again" when i try to do my configuration. I only want it to stream music from my ipad to my stereo. I would really prefer to do the set up only using an ipad, if at all possible.
I was given a shiny new Airport Express for Christmas. As i was staying at my mum's for two weeks, I plugged it into her stereo, and got it working. This was configured to join her existing wifi network, using only my iPad to set it up. The airport utility software was not used, as i didn't know it existed. All worked fine.
It looks as if my router is running WEP. So i gather i need airport utility to configure it. Airport utility says it can't detect a base station anywhere, even when inches away. There don't seem to be any options to get it to work differently.
I have reset and factory reset the device many times.
Some level of wireless access must be working on it, as it appears on my wireless list as a possible "set up airport express base station"
I go through the menus to set it up in the same way as at my mum's: selecting my existing wifi network to add it into, setting up a new base station password, and then watching and waiting.
Among the different resets and re-attempts i have done, it varies slightly in behaviour: the last time it failed it didn't get as far as asking for my wifi password.
After the error message i can't "try again" as suggested. It wipes out my wifi access, so i need to delete my existing wifi network (on the ipad) and re-add it to get an internet connection back again. I need to do a reset to get the "configure new base station" message back.
The differences between the two houses:
The stereo connection is different in the two houses: single 3.5mm jack into mum's; 3.5mm jack split into two needed for our stereo. I know it says you need to plug into the stereo first (and I have), but surely the device doesn't care which cable i use?
At my house, the wireless router and airport box are within 4m of each other. At my mother's it's more like 20m.
My wireless router is from O2 (now Sky), my mother's is plusnet.

It looks as if my router is running WEP.
Virtually no security at all there, as there are numerous free utilities available on the Internet that will crack a WEP network in seconds. You might as well run the network wide open, since WEP offers about the same level of protection.
You will not be able to configure the Express using an iPhone, iPad, or any version of AirPort Utility that is 6.x or higher with your router set to use WEP "security". They will not work with WEP, since it is so long out of date and non-secure.
An older version of AirPort Utility 5.x might allow you to configure the Express using WEP security, but with no protection anyway, this would be of little value.
See if your router can be configured to use WPA2 Personal security or WPA/WPA2 Personal security. If it can, then you will be able to use an iPhone, iPad, or any version of AirPort Utility to configure the Express in just a few minutes.
If your router cannot be configured to use stronger current WPA settings, now might be a very good time to ask your service provider for a new router.

Time Capsule Airport Extreme Airport Express - IP Address Issues, Internet dropping...

I have a brand new Time Capsule 3TB functioning as my main wireless router from a Motorola SB6141 Cable Internet Modem. I have a Airport Extreme and Airport Express extending the network from my Time Capsule 3TB. After the intial setup there were no connection issues for several days. However, yesterday I began to experience issues where the Time Capsule starting telling me that other devices on the network were trying to assign IP Addresses to change from DHCPand NAT to Bridge Mode. What is the best solution for this? My temporary solution is just to do a hard reset of the SB6141 which seems to alleviate the issue until the next day. Please help!

There is definitely some issues with the SB6141 modem and the new AC version Extreme and TC.
I have recommended to several people to use a crossover cable or a small 10/100 switch.
Either is a very cheap item and I cannot promise a solution but it has helped.
Net time it happens please login with airport utility and take a few screenshots of the TC summary page and internet tab and post them here.

Multiple Airport Express Extension Configuration

I recently installed 1 Airport Extreme and 4 Airport Express' which I configured to "Join the Network" for the Airport Extreme acting as Base Station. I have to configure these in an "L" shaped fashion with the base station acting as the tip of the shorter end of the L (given where the modem feed is located). I am currently getting light signal strength on the furthest reaching Express (1 of 3 bars). I configured each of the Express' to "join the network" of the base station Airport Extreme. Is this is the correcct configuration to maximize signal strength, or should I have selected the closet Airport Express as the device to extend off of to obtain maximum signal? Any insight is greatly appreciated. These are all the latest Airport devices (purchsed two days ago).

Thanks for the clarification. I would try the "join" configuration for the "Far AX" to see if everything will function as you require.
If devices do need more wireless signal strength in the area of the "Far AX", (and due to obstructions between the "Far AX" and the AirPort Extreme), you would need to connect the "Far AX" to the AirPort Extreme using an ethernet connection and configure it to "create a wireless network" using the same network name, security and password as the rest of the wireless network.
If you can't run an ethernet cable, you might want to take a look at a pair of ethernet powerline adapters to allow the AC wiring in your home to transmit the ethernet signal. Post back if you need more information on this type of configuration.
There is always some bandwidth loss when devices use wireless to "extend" due to the overhead of receiving a wireless signal and then having to re-broadcast it. With an AX, on average, it's about 10-15% per device. So, with 3 AX devices set up to "extend", the bandwidth on the network is going to drop 30-40% or so. That's really not as bad as it might sound.
One of the advantages of connecting an AX to a main base station using an ethernet connection is that maximum bandwidth on the network is maintained. That's why commercial networks are designed with each wireless access point connecting back to a main router using an ethernet connection. "Extending" devices can then be located exactly were they are needed and you don't have to worry about them having a strong signal to connect back to a hub using wireless only.

Airport Express (n) signal issues with Powerbook G4

Here is my setup:
1 Airport Express (n)
1 Cradlepoint CTR500 router
1 Lenovo PC Laptop
1 Powerbook G4 12"
I have a printer hooked up to the Airport Express as well as my stereo. I have the AX set to 802.11n (b/g compatible) for the Powerbook. My laptop (PC) is n. The Powerbook is approx 10 feet away from the AX, and there is a wall with a door between the two. No electronics are between in the wall, etc. Its a pretty strait shot, except for the wall.
I have noticed that the Powerbook will show 5 bars for Airport, and after a little bit, go down to 2 bars, or even 1. It will stay there, couple of mins at the most, then shoot back up. Sometimes I have to disconnect (turn airport off) and then reconnect to establish 5 bars.
Now, I have also noticed on my PC that (being 3 feet away from the AX) I will sometimes go from 5 bars to 4, and my laptop will register anywhere from 14 Mbps up to ~150 Mbps connection. It settles around 72 Mbps when the Powerbook is connected to the network. So why under normal web page browsing, does my speed drop to 14, 28, 36 Mbps, yet show signal strength at 4 bars, or even 5, usually when the Powerbook is connected? In addition, and I understand that the 54G rated Powerbook will slow the network down all around, why is it that the Powerbook will drop from 5 bars down to 2, or even 1 in the airport menu? Is the AX changing channels? I have manually set it to channel 8 to see if that was the problem, and it didn't seem to solve anything.
I am kind of at a loss here. Perhaps interference? I do live in an old 100+ year old house, so that might be an issue? I will say that when I set it to N 5GHz, my laptop will connect and maintain a 300 Mbps speed. That's pretty good IMHO. So since that stays connected properly, I can only assume that it is a 2.4 GHz interference issue with neighbors, upstairs phones (this is an apartment) or other devices perhaps.

I think you're probably right that you're getting intermittent interference at 2.4 GHz.
Suggest you try [iStumbler|http://istumbler.net]. Monitor it for a day or so to get an idea of which channels your neighbors may be using. Then, set the AX to one as different from the others as possible. If the interference problem returns, try another open channel.
Also, try activating interference robustness on the AX and Powerbook.

AIRPORT EXPRESS AND CONFIGURATION PROBLEM.YELLOW LIGHT NEVER STOP FLASHING.

good morning yesterday i bought an Airport express device.when I tried to install it ,the yellow light never stop falshing,for that was impossible to me to configure airport express.Do you have any idea to solve this bad problem?please help me!.thanks a lot.

Hi Irenefromitaly,
have you tried to configure your Airport Express via Cable? That's faster and easier.
Or you press the reset button for 5 secs and keep your airport utility searching. wait for some minutes, its takes some time wirelessly..

Time Capsule Airport Express Best Configuration for Backups & Internet

I have Time Capsule as a main router connected to a cable modem downstairs, plus Airport Express (new with firmware upgrade 7.3.2) in my office upstairs to extend the network. Two things keep happening:
1. Backups work sometimes and sometimes not although I am connected to my WPS secured network
2. Frequently lose internet connection, as in every hour or so; alternately nice and fast, then none at all. Most of the time I have a SNR of about 37.
Is there some optimal configuration settings for TC and Airport Express that could reduce these occurrences? Is there, for example, something I need to do with the Access settings on one or both?
Thanks for any help.

Since it still looks like you will need to support 802.11g wireless clients (your iPhone), the best radio mode for the Time Capsule (TC) will be the default "802.11n (b/g compatible." Since this is running in the 2.4 GHz radio band, you can use iStumbler (or similar utility) to determine if there are other Wi-Fis in the area; find out what channels they are operating on; and try changing channels on your wireless network to see if this will help provide the best SNR.
1. Backups work sometimes and sometimes not although I am connected to my WPS secured network
Are you actually using a WPS, or did you mean WPA?
2. Frequently lose internet connection, as in every hour or so; alternately nice and fast, then none at all. Most of the time I have a SNR of about 37.
If directly connected to the TC by Ethernet do you still lose the Internet connection periodically? If so, how about when connected directly to the cable modem?

Airport Express and DNS Issues

Recently I bought a Airport Express and i have been using it connected to a ADSL modem (modem is using PPPoE). Before that i used to have a D-Link wireless router connected to the modem, with no issues. Airport Express is working as bridge mode.
I was having trouble with my Macbook connecting some websites (with Windows computer it was ok), and I could solve it by adding DNS preferred addresses on System Preferences. Although it completely solved my home network problems, every time I go to a place where the preferred DNS is different, I have to exclude the addresses from System Preferences to internet to work fine.
Can anyone help me with that? Is it a Airport Express bug?
Thanks for any help.

That suggests to me that you're expecting the "ADSL modem" to perform router functions. Is it capable of that? What is the brand and model of that modem? If the modem can't perform router functions, your Express shouldn't be in bridge mode.

If something on your LAN is performing proper DHCP functions, that "something" should provide your MacBook with usable DNS addresses without your having to declare them manually.

Samsung CLP-300 attached to Airport Express Base Station: Issues

I have found that my Samsung CLP-300 printer, which is connected to my Airport Express Base Station via USB, refuses to print after printing one document. After restarting my Airport Express Base Station, I found that the printer would start printing again, but only one document - afterwards, I required a base station restart before the printer could print again.
Does anybody know how to rid this problem? I would like to be able to print consecutive documents without needing a reboot.

Hi Eric. I've had the same troubles for quite some time. I've had limited success setting the printer up as an IP Printer. Here's a link to another discussion that might help you out. Good luck!

Airport express multiple configuration and iOS utility

Hi
Just wondering if there is a way to toggle configs on iOS 5 devices iPad :iPhones with the new airport utility?
Reason : I use it as an audio device to my sound system , but when I travel ( hotel , offices , etc) it becomes my own hotspot while cconfiged as a router from the stored configs on the device .., But I have to use my MBP !
Or change it before I leave ....
Any thoughts ? Thanks

do I need to use my computer to change the profile before unplugging the airport express and taking it with me wherever I am going,
Yes, unless you have another device handy on the road with a 5.x version of AirPort Utility installed.
or will it switch automatically
No, you must manually "switch" to the profile that you want to use at any given time.

Airport Express Ethernet Out Issue

I setup my AirPort Express N yesterday and everything is working fine except the Ethernet port. I've been trying to set it up to connect to an iMac with no airport card to the Internet. Followed the manual setup to join a wireless network and clicked the allow Ethernet clients but it still doesn't work.
I've tried resetting my comp and the main wireless router/modem. I have the Verizon fios modem/router combo. The light on the AE is green and I'm able to see it in Airport Utility.
Any ideas why the Ethernet port isn't working?

You did everything right and everything looks OK to me. It's not a self-assigned IP address and the DNS address is that of your router. That's OK too.
Make absolutely sure you're using a good Ethernet cable.
The only other thing I can think of is to factory reset the Express, connect it directly to your Mac's Ethernet port with an Ethernet cable known to be good, and turn off the Mac's wireless. That ensures the only way to communicate with it would be through the wired port.
If AirPort Utility sees it then Ethernet is OK and something else is wrong.
If not, it's definitely broken.

Airport Express & Extreme Security issues

Hi Guys
I've just installed and setup an airport extreme, which I am using as a wireless router and Airport Express. They are both in different rooms and I can wirelessly connect them all and see them all on my iMac (Hurrah!)
BUT currently none of them have any password protection and as soon as I try to put a password on either of them through AirPort Utlility (I have chosedn the WPA/WPA 2 Personal option) I cannot get the Express to see the Extreme. I can put a password on my Exteme no problem but then I can't get the Express to connect to it and I cannot see the Express in my AirPort Utility. I can get round all of this by plugging in the Express into the Extreme with an ethernet connection but I want it all to be wireless.
I think I am doing something wrong on the iMac in setting them all up so any help would be appreciated! I am running OS 10.4.11
Thanks Guys!
Matt & Kris

Once you have put a security password on the AirPort Extreme you need to reconfigure the AirPort Express device with the correct security protocol and password.
To do this, you should connect to the AirPort Express device from a client computer using Ethernet cable instead of trying to do it wirelessly. Once you have reconfigured it using Manual Setup in the AirPort Utility application, you can revert to wireless connections.
