Airport extreme connection problem after adding computer to network

just added new imac to my network and for some reason my older imac {dome desktop} seems to have stopped recognizing the AEBS. the older imac was hooked up to the AEBS by ethernet and when i moved it across the room it fails to read the AEBS. I had installed the airport card a few mos ago and i know it worked...although most recently was ethernet connected. I cannot be certain the new computer addition is even related but seems to be. Have checked all the airport utility settings and see no issues. I did fool around with some network sharing features on the imacs so ? if that can create issue sharing the AEBS. Interestingly the affected imac does detect the AEBS in the utility app but times out when attempting to connect. also think i may have done recent AEBS download upgrade and see threads related to that as poss issue . have reverted back to older AEBS software without success. new ibook and new imac detect/connect without problem. Any thoughts out there??? thx for any help.

Is your AEBS configured to create an 802.11g compatible network? It must be for the iMac G4 to connect.
What channel is the AEBS configured to use?
If the AirPort Extreme card in your iMac G4 is from the US it can only use the channels between 1 and 11. If your AEBS is from somewhere else in the world it can use other channels which are not available for use with equipment from the US.
If your AEBS is not using a channel between 1 and 11, change it and see if your iMac G4 can connect.

Airport Extreme Connection problem with new MacBook

Help-
For the past 2 years, I have had no problems with my Airport Extreme. My MacBook Pro (2006), My wife's iBook G4 and two AirPort Express units used as remote speaker connections have been rock solid. Both iPhone and one iPod touch work like a charm.
I just got my wife a new MacBook and since it came in and was connected, my Air Port Extreme has been nothing but a problem, requiring a hard reset every couple of days. As long as that MacBook is not connected, everything is fine.
Anyone have any ideas? Only the MacBook is using 802.11n. It is so frustrating, that my wife want to use her old iBook so if this can't get fixed, the MacBook is going back to Apple.

Welcome to the discussion area!
From your description, it sounds like the wireless communications between the AirPort Extreme and your wife's MacBook are picking up some sort of wireless interference from another source such as a cordless phone or another nearby security system.
I suggest that you try different channels for your wireless to see if you can find a setting with less interference. To do this, you would:
Open Macintosh HD > Applications > Utilities > AirPort Utility
Click on the AirPort Extreme and then click Manual Setup below
Click the Wireless tab below the row of icons
Look for the Radio Channel or Channel setting
You may need to hold down the option key as you click on the selection box to display all available choices.
Start at the highest channel and work your way down, or start at the lowest and work your way up.
Click Update at the lower right of the window to save your current setting and the AirPort Extreme will restart in 20-25 seconds.
It will take some time to find the optimum channel for your network, so proceed slowly and take a few notes as you go.

Hard drive and airport extreme connection problem.

Hi folks,
I have an airport extreme and a WD 1TB pasport for mac hard drive. I had it connected for ages and used it to load movies onto to keep my macbook empty. I had no problems accessing it wirelessly through Finder until today when i configured the extreme to run at 5ghz. When i try to connect now, it tells me that the ip address is wrong but im connected to the extreme for internet. Any clues or solutions?

your Airport Extremes ip address is the red square, Then your going to copy that
So in the red box instead of Http:// we are going to put ftp:// then you should get
a pop up say connecting to server and I hope you do get that.

Connectivity problem after adding a second WLC

I have a client with two identically configured WLC's running 7.0.230.0 with approximately 370 AP's. We are currently testing before going into production and found that once the 2nd WLC comes online (same mobility/RF group), the clients are no longer able to connect / obtain an IP address. We removed all security and still had the same issue when the 2nd controller came online. This sounds like a bug and I'm thinking about upgrading to 7.2x, however, that requires upgrading the MSE/NCM. Although I don't mind doing this upgrade, I was just wondering if anyone else has ran into this issue.
I did run both configuration files through the WLC Config Analyzer and nothing seems to jump out other than some typical RF issues.
Thanks,
Bob

Simon,
No IP Conflicts. Ironically, when we broke the Mobility Group, everything is working fine and clients are able to obtain their IP addresses from the DHCP servers.

My laptop compaq presario will not connect to the Internet anymore after buying airport extreme. Why? It detects the network, accepts my password, but will not connect to Internet.

My laptop compaq presario will not connect to the Internet anymore after buying airport extreme. Why? It detects the network, accepts my password, but will not connect to Internet. I tried to repair connection, tried to reboot modem several times, I even updated my computer. Nothing. All it says is that it does not detect modem. Why?

Welcome to the support community group.
First, are you sure that your AirPort Extreme has been configured correctly and is properly connected to your modem?
Begin by telling us how you have things connected and if the Airport Extreme is replacing a previously owned router or is this an entirely new installation?
First be sure that your modem is working and properly connects you to the internet using an ethernet cable directly connected to your laptop. Once you're sure that's working, reset the AirPort to factory defaults by disconnecting it from power and pressing and holding in the small reset button on the back for 15 - 20 seconds while you reconnect it to power. Then turn everything off for 5 minutes. Connect the Airport to your modem with and ethernet cable to the Airport WAN port on the back (check the user guide to make sure you connect the cable to the correct port) then connect a second ethernet cable between the laptop and one of the LAN ports on the AirPort Extreme.
Then power up the modem first, wait 5 minutes and then power up the Airport, wait 5 minutes and finally power up your laptop.
Then run the airport configuration utility from your laptop. Since you're not using an Apple computer, be sure that all of your firewall, and virus blocking and checking software is disabled before you run the airport configuration utility. Once you run the utility, it should detect your AirPort and allow you to use the configuration wizard to set things up.
Check back if you're still having problems.

I just installed Airport Extreme. It works as a wireless network on my Macbook. It won't connect with my Windows Visa PC. Message reads: "settings saved on this computer for the network don't match requirements of the network.

I just installed Airport Extreme. It works as a wireless network on my Macbook. It won't connect with my Windows Visa PC. Message reads: "settings saved on this computer for the network don't match requirements of the network." I seem to need to enter a security key/passphrase to connect to the PC. Where do I find them?
Thanks for your help.

I assume that you have Wireless Security enabled on your AirPort's wireless network. The issue maybe that the PC is unable to use the WPA password itself and will require using the Equivalent Network Password instead.
To get this password, you will use the AirPort Utility from the MacBook:
Start the AirPort Utility > Select the AirPort base station > Manual Setup
Now, before doing anything else, go up to the utility's menu bar at the top of the screen, and then, choose "Base Station," and then, Equivalent Network Password from the drop-down menu. You will see two items: 1) WPA Password, which should look familiar to you, and 2) WPA Pre-Shared Key. It should be a long hexidecimal set of numbers and letters. Jot down this second item.
You will want to use the value you just jotted down when entering the password from the Windows Visa PC.

Fix for Airport Wireless Connection Problem stating Self-Assigned IP and not wanting to connect in Lion OSX.

Fix for Airport Wireless Connection Problem stating Self-Assigned IP and not wanting to connect in Lion OSX.
Bought my girlfriend the newest Macbook Pro 13" and began experiencing problems with my wifi the moment we got home. Her Macbook would not connect to our home Wi-Fi while my old Macbook Late 2008 running Snow Leopard connected without a problem. Airport would say that it had a Self-Assigned IP address (168.x.x.x). Did not realize it was a Lion problem until after using her Macbook Pro and becoming jealous of the new OSX, I upgraded. Soon after I was unable to go online. Luckily I had my iPad 2 and I began to scoure the net for help. Ran into allot of suggestions but it was not until I tried the following all together was I able to share the good new, from my Macbook. Hope this works:
First go to Preferences > Network and click on the cog next to the + and - on the sidebar and click Set Service Order
     - Move Wi-Fi to the top and click ok.
     - Set location to Automatic
     - Click Apply
     - Click Advanced
     - Click the "-" on the selected Wi-Fi router you wish to connect to
     - Click Apply
     - Click Lock to Prevent Further Changes
Go to your Mac's harddrive, (Macintosh)
     - Go to Library > Preferences > SystemConfiguration >
     - Delete "com.apple.airport.preferences.plist" file
Turn off your computer
     - push and hold Option+Command+R+P
     - turn on computer
     - when the grey screen turns on you will hear the OS X "ON" sound (for lack of a proper term) and it will momentarily restart.
     - you will once again hear the "ON" sound, let go of all keys.
     - this resets your PRAM
Go to Preferences > Network > Advanced > + sign
     - click Choose a Network
     - Select your network and enter password
Viola!!! I tried this on my Macbook Late 2008 and my girlfriends new Macbook Pro 2010

     No you are clearly mistaken. The Self-Assigned IP address problem exists on many Macbook Pro models, including the current model, which I mentioned as being the original computer with the problem. While my 2008 Macbook is older it was working perfectly on Snow Leopard and didn't suffer issues until switching to Lion. So clearly the problem exists on the operating system and not so much the hardware.
     I called Apple Support and they had no fix for the problem and told me that this would hopefully be addressed in a subsequent update. It wasn't until I came accross the answer after trying many different methods that I got both of the Macbooks to connect to my router. Otherwise I wouldn't or could not have been surfing the internet for the last 4 months.
Cheers.

I'm trying to extend the range of an Airport Extreme 802.11g by adding an Airport Express 802.11n. I set the Express up to join the existing network, but it does not make any difference in the range of the network. What's wrong?

Let me see if I can help you with the basic WDS configuration steps:
Note: To help facilitate the setup, temporarily connect the AXn directly to the AEBS LAN port using an Ethernet cable. Once the setup is complete, you can move the AXn to the desired location. For all configuration steps you will be using the AirPort Utility. Before starting, be sure to jot down the AppleIDs for both base stations.
802.11g AirPort Extreme Base Station (AEBS) Configuration
AirPort Utility > Select the AEBS > Manual Setup > Wireless tab
Wireless Mode: Participate in a WDS network
Manual Setup > WDS tab
WDS Mode: WDS main
Allow wireless clients (checked)
WDS Remotes: <enter the AppleID for the AXn here>
Click on Update and allow the base station to restart.
802.11n AirPort Express Base Station (AXn) Configuration

Airport Extreme setup problems on existing WDS network - Please help!

I just bought a Time Capsule and have setup a WDS network for the house. The Airport Express joins the network just fine as a remote WDS device. I cannot get the Airport Extreme (v5.7) to join the same network. It just continues to make a *separate network with the same name* despite the Channel being the same, the WDS being set to remote, and the main ID of the Time Capsule has been put in correctly. In other words, since I setup the airport Express correctly, I cannot figure out for the life of me why the Airport Extreme is not joining correctly.
PLEASE HELP. I've been trying this for 6 hours now and countless total restarts by hard resets of all the equipment.

Hello arthung. Welcome to the Apple Discussions!
Let's double-check your WDS setup ...
(Note: To facilitate the WDS set up, place the base stations within near proximity of each other during the set up phase, and then relocate them to their desired locations when complete. Also, jot down the AirPort IDs for each of the base stations to be used in the WDS.)
o Perform a "hard" reset on the Time Capsule (TC) and a "hard" reset on the 802.11b/g AirPort Extreme Base Station (AEBS).
Main Base Station Setup - TC
o Click the AirPort status menu in the menu bar and choose the wireless network created by the TC.
o Open AirPort Utility.
o Select the TC, and then, choose Manual Setup from the Base
Station menu.
o Click Wireless in the toolbar, and then choose “Participate in a WDS network” from the Wireless Mode pop-up menu.
o Click WDS and then choose “WDS main” from the WDS Mode pop-up menu.
o Select the “Allow wireless clients” checkbox if you want client computer to connect to this base station.
o Click the Add "+" button and enter the AirPort ID of the AX.
o Click Update to send the new settings to the base stations in the WDS.
Remote Base Station Setup - AEBS
o Click the AirPort status menu in the menu bar and choose the wireless network created by the AX.
o Open AirPort Utility.
o Select the AX, and then, choose Manual Setup from the Base Station menu.
o Click AirPort in the toolbar and click Wireless. Choose “Participate in a WDS network” from the Wireless Mode pop-up menu, and choose the same channel as the main base station from the Channel pop-up menu.
o Click WDS and choose “WDS remote” from the pop-up menu.
o Enter the AirPort ID of the main base station in the WDS Main field.
o Click Update to transfer the settings to the base station.

I have a 1st generation AirPort Extreme and want to create a guest network, can I? If so, how? Can I do this by adding an Airport Express?

I have a 1st generation AirPort Extreme and want to create a guest network, can I? If so, how? Can I do this by adding an Airport Express?

I have a 1st generation AirPort Extreme and want to create a guest network, can I?
This version of the AirPort Extreme does not have guest network capability.
Can I do this by adding an Airport Express?
Why not simply buy a new Airport Express.....which does have main and guest network capability*.....and sell the AirPort Extreme?
* The AirPort Express will need to connect to a simple modem.....not a modem/router or gateway type of device.....for the guest network feature to work correctly.

My house has a wired ethernet to many rooms. Can I have my imac connected via ethernet (then to router via comcast cable modem) and also have my airport extreme connected to another outlet?

Not experianced in networking. Current working setup is wireless network with airport extreme. Having problems with signal so may need to expand network with another airport. My house has a wired ethernet to most rooms. What is the best approach to maintain wireless network and also use ethernet wired connections where convienient?

I now wish to add a second Airport extreme but am considering a hard wire connection with 100 ft of cat 6 cable from the Time capsule to the second Airport extreme.
Excellent plan.
Can my network operate properly to extend the network with both a wireless and wired extend functionallity?
Yes, but don't get confused about the second AirPort Extreme, as it would not be configured to "extend" a wireless network.....it would be configured to "create a wireless network" using the same wireless network name, security settings and password as the Time Capsule network. Configure the second Extreme in Bridge Mode.
This Apple support document will show you how to hookup and configure the second AirPort Extreme:

Airport extreme connect to my wifi router (wep 128bits) but no extend

hello,
as i said, my airport extreme connect to my router, get an ip by DHCP, say it's connected to my network but it's say it can't extend the network.
when i launch the airport utility on a computer connected to my router it discover the airport extreme but can't configure it (get error 10057), but it see the airport extreme, this mean it's connected to my lan...so why it can't extend the wifi network ? an idea ??
best regards
Chris

Yes, even an Airport Express....
Extreme
Express
Time Capsule

Must be Apple Airport devices in order to extend a wireless signal.

Just bought a new Airport Extreme BS. After setup my iphone4 won't find the network (not even with manual entries), but my iMac (2009) does. What is wrong?

Well, after another call with Apple support and the engineers, no success. After spending over 20 hours trying to debug this, I give up. Apple was basically fishing for a solution with trial-and-error settings on the iphone. Then they wanted me to plug in software to log my iphone connections to the router, etc, etc., etc., at which point I decided I no longer wanted to participate in their testing process and will simply return the router.
25 hours of my life I'll never get back.
Big bummer, and frustrating for all the obvious reasons.

Timeouts and connection problems after 5.1(2) upgrade

AIM/chat and some other programs are having timeout/connection problems after upgrade to 5.1(2). I am using S241 also. The connection problems stopped when the IPS was set to bypass. Rebuilt IPS and left sigs at default settings and problem is still happening. I am not seeing any of the IPs that are having the problem in the Event Viewer or on the Events in the IDM.
Any known issues with the 5.1(2) that would cause this type of problem?

I don't know specifically, but I did notice that 5.1(3) was released today.

Can airport extreme connect using a mac mini. the base station is not recognized so i cannot configure it manually

can airport extreme connect using a mac mini. this airport extreme wont connect to internet via my cable modem. I cant set it to bridge mode because it doesnt appear as a base station in airport utitlity...help

First, is your AirPort Extreme Base Station (AEBS) a 802.11n, 802.11g, or 802.11b model? Second, what is your primary goal for using this base station? Finally, is the AEBS the only router in your current network configuration?
