AirPort Extreme no longer accepting password

We have a Windows 7 PC, iPhone, iTouches (2) and Mac and WiFi printer. Until yesterday, everything was routing fine through the AirPort to our Comcast internet connection. Now the Airport won't accept anything but the Mac. Password is correct, but iPhone and iTouches can't get through. PC gets nowhere. Printer useless. Help!

When changing ISPs (or networking equipment) it's always a good idea to start from "scratch" in configuring your equipment.
I would recommend that you do the following as a minimum:
Power-down the modem, AirPort base station, and computer(s).
(OPTIONAL) While all of the devices are powered-down, perform a "factory default" reset on the base station. This will get it back to its "out-of-the-box" configuration and make setting it up much easier, especially if you use the "Assist me" process within the AirPort Utility. (ref: Resetting an AirPort Base Station or Time Capsule)
After the base station resets, go ahead and power it back down.
Power-up the modem; wait at least 10-15 minutes.
Power-up the base station; wait at least 5-10 minutes.
Power-up your computer(s).
In this basic configuration, computers connected to the base station, either by wire or wireless (as appropriate for the base station type), should now be able to access the Internet through the ISP's modem. Once Internet connectivity has been verified, you can use the AirPort Utility to configure the base station for wireless security and any other desired options.

Current model Airport Extreme no longer accepting DHCP WAN assignment

I woke up to my airport extreme not connecting to my ISP.
I'm using DHCP on the WAN side, and my Airport can no longer retrieve a DHCP address. It appears the Airport does find the ISP's router address (the router address and subnet mask are populated), and my ISP sees the DHCP request. However, my Airport will not accept the DHCP response and assign the address. (My Internet connection is over a fiber line and I use a "portal" for access. As such the ISP can see any and all packets for troubleshooting.)
I purchased my Airport new in November, 2011.
If I connect my Macbook Pro directly to the portal, I get a new address off the ISP.
My ISP then created a DHCP reservation. Still no luck. I then tried assigning a static address. That works as well.
So it seems my router is not accepting the DCHP response or assigning the address. My ISP uses DHCP3 on Linux.
Any ideas?

So it seems my router is not accepting the DCHP response or assigning the address. My ISP uses DHCP3 on Linux.
I'm not aware of any incompatibilities with version 3 of the DHCP service that would cause your AirPort not to accept an IP address from your ISP ... although anything is possible. Is this something that your ISP has just updated their DHCP services to or has this been their configuration for a while?

Airport Extreme won't accept password request from DirecTV wireless adapter

My Airport Utility is running on PC (Windows XP). The DirecTV wireless adapter "sees" the network, and I get to the password screen but it can't get the password approved by Airport. Anyone know a fix?
I've already updated Firmwear, rebooted everything, etc. Other wireless things working fine including new setups, so it's not the router unless I need to change some settings
Thanks, Marty

wyhoser, Welcome to the discussion area!
Are you by chance using WPA or WPA2?
WPA: You can use WPA if you upgrade your iBook G3 to OS 10.3. See KB 107795, AirPort Card: When You Can Join a WPA Network.
WPA2: Sorry, but the iBook G3 can not join a WPA2 protected network. You will need to drop back to WPA or WEP.

Airport Extreme no longer recognizes my Express when I try to password protect the network

When I try to protect my network with a password, my airport extreme no longer recognizes my airport express. How can I fix this so I can connect my network and still use my network for airtunes??

I think the initial problem is that your iPhone was connected to an open network that wasn't yours.
Go to Settings > WiFi and "Forget" the network created by that AirPort Extreme, it's older than dirt. Forget your neighbor's network also.
Perform the equivalent actions with your Mac: System Preferences > Network > Wi-Fi > Advanced... Delete every network that appears, including your own.
Then, connect to your own network on all your devices, after which you ought to be able to use any of them and configure your Extreme without any difficulty. You may need to start over with a "hard reset" on both the main AirPort Extreme and the one extending its network.
Does this have anything to do with the fact that 'Back to My Mac' is probably enabled?
Not exactly, but using iCloud Keychain will populate all your devices with the names of preferred networks that any of them connect to, no matter where they are. I don't know why Apple considers that a beneficial feature.

How do I prevent other Mac users from changing my Airport Extreme Network Name and Password within the Airport Utility?

How do I prevent other Mac users from changing my Airport Extreme Network Name and Password within the Airport Utility? My company is using an Airport Extreme in our office now and I want to prevent other employees from messing with the network/settings. Is there a way to place a password on the settings to allow only the admin to access the network name and password?

Hi - you have will have to change the device passwords on all the base stations and then don't give them to anyone except the administrators and tell them not to save them on their computers that use the older versions of the Airport Utility - for the newer versions like the mobile apps, as soon as you enter the pasword it is saved and is visible in the advanced pane along with the network password - so if anyone gets a hold of your iPad or iPhone, they can edit the whole network - I have this same issue with my networks in the office and it is inconvenient but doable - I hope this helps

A visitor from Japan is unable to connect an iPhone or a Macbook Air to my Airport Extreme it says the password is invalid but the password works for other devices?

Am unable connect a MacBook Air to Airport Extreme using a valid password get an error message that password is invalid. The Mac belongs to a visitor from Japan?

Test by simplifying the name for the wireless and set names for the two bands..
eg AE24ghz and AE5ghz.
Then use no security.. does the MBA and iphone then join..
If so put back security.. wpa2 with simple password, no spaces pure alphanumeric mixed case and numbers.
If no connection test with fixed channels .. say 11, 9, 6 in that order for 2.4ghz.
Don't worry about 5ghz for now.. if it still won't join it is somehow incompatible.. you need to reset the Japanese devices but I am not sure how.

I put my password into my airport extreme and says wrong password what can I do thanks

I put my password into my airport extreme and says wrong password what can I do thanks

If your password is incorrect, perform a "soft reset": momentarily depress its reset button, and launch AirPort Utility. A "soft reset" will lower the Extreme's shields for about five minutes, so that you can configure it with a new password.
AirPort Utility is in your Mac's Utilities folder.

Airport Extreme refusing to accept more than 7 clients

Our airport extreme (7.2.1) used to be happy with at least 11 clients. Four people in our office now own iPhones. When all four iPhone owners are in the office, not only are they unable to connect to the airport extreme, but some Macs are also unable to connect. Our airport extreme refuses to accept more than 7 clients. The logs in AirPort Utility don't show anything related to client refusals. All but one of the Macs are on Tiger - the other is running Leopard.
Any thoughts appreciated.
Thanks
Paul

It is the extreme, my mistake in the previous post.

Airport Utility won't accept password, though it's the same that I'm using for my wi-fi access.

Hello,
First-time asker, multi-time reader. Could not find this situation exactly in other posts.
I’m having trouble accessing two different Airports.
I have an Apple Airport Extreme 802.11n (4th generation) handling the wi-fi for 3 laptops and 2 iPhones, but I needed to extend the range within the home one room so I got a Airport Express.
It’s showing up in the Airport Utility when I try to set it up, but each time I try it asks me to “enter the password for the selected airport wireless device.”
I type in the password I use when I need to access the wifi (the “WEP” password I guess?), but it’s never accepted. I’ve tried this on 3 of the Macs.
After reading some relevant comments here, I confirmed this as the “Airport network password” with the Keychain on 2 Macs. My Keychain does not show a “Base station password” at all.
I typed it in on 3 different keyboards, no caps lock, etc.
I’ve tied adding “$” and using “public,” to no avail.
I’m assuming that the password it’s asking for is the same password same as WEP password, the one that’s used when a friend visits and wants to use my wi-fi instead of 3G. It’s my network password. Is that right? Or is there some other password needed? My Keychain does not show a “Base station password” at all.
It does this for the existing Extreme as well as the Express.
It asks for the password whether I try to update the firmware as directed (7.4.2 to 7.6.1 for the Express, 7.5.1 to 7.6.1 for the Extreme), or if I click “Manual” to set up the Express.
Same thing happens using the Apple Airport Utility App on my iPhone.
I did the factory res-et thing on the Express, and it showed up with a generic name described as “with factory-default settings” so then I clicked Continue. This brought up the box saying “Are you sure you want to switch wireless networks? Setting up this AirPort wireless device requires switching wireless networks. Switching wireless networks may interrupt your connection to the Internet.”
I don’t want to switch, I want to add the Express to the existing Extreme network, so I’m (ignorantly) hesitant to say yes. Besides, it will probably just ask for a password, so I’m back to square one.
I’m mainly working on a Second Gen MacBookAir (3,2), Intel Core 2 Duo with AirPort Extreme (0x14E4, 0xD1), Firmware Version: Broadcom BCM43xx 1.0 (5.10.131.42.4) 802.11 a/b/g/n. But this situation is the same on multiple Macs and iPhones.
All my devices work fine on w-fi, but none can access the Airports using the password as mentioned above with the goal of updating firmware and setting up the Express.
So anyone have any suggestions for this issue the password problem?
Just Wonderin.
Thanks so much.

Jaime...
Open Keychain Access /Applications/Utilities
Select Passwords on the left.
type base station in the search field top right corner of the window.
Right or control click the base station keychain then click Get Info
Select the Attributes tab.
Click: Show Password
Now, you can use that password or set up one of your own. If you want to create a new password right or control click the current base station keychain then click Delete.
Now open Airport Utility /Applications/Utilities
Select the base station on the left.
Click Manual Setup then select AirPort from the menu then select the Wireless tab
Type in a new password, then type it in again to verify.
Then select: Remember this password in my keychain
Then click Update.
If at some point you forget the password for your wireless network just follow the instructions for Keychain Access above.

Airport extreme takes long time to establish stable Wifi to Internet connection

Hi,
I am using Airport Extreme together with Airport express (to extend the Wifi signal). When I connect my MBP, MBA or my PC to the Wifi network it takes (in 90% of cases roughly) quite a long time - even up to 20mins - to get stable Internet connection. The connection drops due to time-outs or with "DNS server cannot be reached" messages. Connectivity on my local network is just fine and does not seem to show similar behavior. After some time all settles down and my connection is fast and stable. The strange thing is that my iPads are not affected by this - i.e. I can browse internet fast on my iPad, but my MBP cannot reach a single internet page at the same time. When I switch to wired connection, everything is just fine from the beginning - no time-outs etc. Sometimes it helps to switch the Airport Extreme off and on again, but it's about a 50/50 chance.
Anyone got an idea what's going on?
Thanks a lot for help!

You have wireless gremlins.. plus voodoo..
It is the nature of the beast.
My recommendation is to clean up, simplify and start over.
1. Reset the AE to factory and start over. This time use all short names no spaces and pure alphanumerics. Same for passwords but longer.
2. While you have problems try using different names for the two bands.. eg AE24ghz and AE5ghz
3. Use fixed channels.. 11, 8, 6 in that order for 2.4ghz and usually one low and one high for 5ghz.. say 36 and 149. (actual number depend on geo-region).
4. Reset the Express to factory and test extend on both the 2.4ghz and 5ghz.. (assuming gen2.. if gen1 just 2.4ghz). The express must get excellent signal to transmit excellent connection.. if it is poor then it will make things worse not better.
5. Use the apple wireless diagnostics.. to help you determine how the signal is in various parts of the house.
diagnostics
http://osxdaily.com/2012/07/31/wi-fi-scanner-mac-os-x-mountain-lion/
http://support.apple.com/en-au/HT202663
There are plenty of these available .. paid for and free but since it is built in give it a go.
6. Setup IPv6 to link-local only.
This setting is here.
7. In the client computers with issues.. clean out all current wireless names.. reboot the computer and rediscover the wireless again.. put in the password and set to remember the network.
With Yosemite.. wireless issues are a given.. expect them.. they are part of the deal.
You might even need to do a clean install of the OS.. any upgrade install to Yosemite with issues should be treated as so normal.. it is just always going to happen.

Airport Extreme no longer recognizes or provides internet to wired devices

Not sure if it was the power outage or an update that is the problem; but, I had a 5th generation Airport Extreme as the center of my home network with a solid connection to the internet for both my wired and wireless components. A few days ago, after a power flicker (all components on surge protectors) my wireless internet would not stay connected more than 45 seconds before dropping and oddly, none of my wired components we showing up on the network or getting an internet signal from the AEBS. After two hours with my ISP technical support personnel we deduced that the problem was the AEBS and the modem was fine. I bought a new AEBS yesterday (the new long cube one) to use until my appointment to have the 5th gen looked at. Plugged that in and instantly my wireless network came back up - rock solid. However, anything I connect directly to the AEBS via ethernet does not get an internet connection or show up in the network. I searched for two days in these forums for a similar problem - but, have gotten nowhere. I used my wired connections for internet phone service and really need to get this fixed soonest. Much thanks for any help anyone can throw my way.

I would find it odd that you would have a replacement AirPort and still not have Ethernet connectivity ... but, of course, anything is possible. The DHCP service on the AirPort provides IP addresses to both wired and wireless clients by default so it shouldn't work for either if there was something amiss with it.
At this point, I would suggest that you try the following:
Perform a "factory default" reset on the AirPort. After it resets it will default to its "out-of-the-box" configuration which is a wireless Internet router that will broadcast an unsecured wireless network with a Network Name of something like: Apple Network NNNNNN.
Without making any changes to the AirPort, try connecting any of your wired devices to it. If it still does not get the proper IP address and network connectivity I would suggest that you try performing a complete power recycle of your networking hardware. Please check out the following AirPort User Tip for details.

My airport extreme no longer recognizes hard drives attached to it. I'm running Mac OS Lion on a Macbook Pro. Any ideas?

I have a 5th generation Airport Extreme. I recently upgrade my Macbook Pro to Lion and then went on vacation. I checked all my hard drives when I returned and my Airport extreme is no longer recognizing my hard drives. I have two WD mac-formatted HDs connected to the airport extreme via an AC/DC powered 4 port USB hub. Both hard drives work fine when they are connected to my computer and light up when connected to the USB hub connected to the Airport extreme. I've reset the airport to factory settings and tried reconfiguring it, but that didn't work. I'm hoping I can get some help from you guys. Thanks!

I suggest you post this issue on the iTunes forum. You will have an audience that is oriented specifically towards this application.
Ciao.

Airport Extreme no longer recognizes external HDD

My Airport Extreme has suddenly stopped recognizing the external HDD I have attached to it. This happened about 2 weeks ago, and has been driving me absolutely insane since (I use this HDD to store all my music, and as such have not been able to listen while I work during this time). I've looked around and tried all the suggestions from other topics, but nothing is working.
• Airport Extreme is using Firmware 7.3.2 -- I did not want to update to 7.5.x, since I saw overall bad opinion about the latest firmware
• My MacBook Pro is using 10.6.7 -- I have all the latest updates from Software Update
• External HDD is a Western Digital 500 GB formatted in Mac OS Extended connect to the Airport Extreme via USB -- reformatting this HDD is not an option at this time
The Airport Extreme has had no trouble with the wireless connection, everything seems to be working for all computers on the network. I am able to successfully configure it using the Airport Utility. The moment I plug my external HDD into the Airport Extreme, I can no longer use the Airport Utility to configure. I receive this error message:
Make sure your AirPort wireless device is plugged in and in range of your computer or connected via Ethernet and try again. (-6753)
If I unplug my external HDD, the error message goes away and I am able to configure the Extreme again. In addition to the error message above, the external HDD does not show up in Network nor on the left side panel when opening a new Finder Window.
I have tried the following:
• I restored the Extreme to factory settings and then reconfigured it using my backup copy of the configuration file. The error persists.
• I have used Disk Utility to repair the external HDD and received no errors.
• I have plugged my laptop into the Extreme via Ethernet rather than a wireless connection. The error persists.
• I have used a different laptop (via wireless and Ethernet)-- a MacBook also running 10.6.7. It also cannot configure the Extreme nor see the external HDD when it is connnected to the Extreme.
I'm at wits end here, and I have no idea what else I can do. This problem happened suddenly and with no explanation, and no Snow Leopard updates have fixed it.
Do you all have any other suggestions?

I just tried switching the HDD to another USB port on the hub, and am still having the same issue.
Hi,
Bob exaggerated a bit (or more); I'm not really a HD guru. I do help folks with Time Machine problems, and sometimes those are HD problems.
It is quite unusual. I'd suspect the hub, cable, or connections.
Try using the same port that your printer is working fine on (leave the printer disconnected).
Try disconnecting the hub and connecting the HD directly to the USB port. It may not recognize it if there isn't enough power, but see if the Airport goes berserk.
Try a different cable, or just swap ends. A plug that works fine in one port may not make good contact (or may short out) in another.

Two Airport Extremes no longer working in tandem to extend network

Trouble has cropped up with my home network, I think dating back to the installation of Leopard (though I'm not sure about that). I have been using two Airport Extreme (both 802.11n) to extend my wireless network throughout the house. For some reason, the two no longer seem to be communicating with each other. I have done factory resets on both, gone through the streamlined setup routine outlined in the Knowledge Base article on configuring Airport Extreme networks, and no dice. The remote station, once set up to extend the base network, no longer appears as a separate station in Airport Utility, and its indicator light is a steady amber. I seem to recall this was the case when it was working, too.
Any thoughts?

Here is some more info. I had a look at the posts on this issue from Nov. 19th, where Jane describes setting up the two base stations in a particular sequence using the assisted (not manual) setup process. My problem is that none of the relevant options ... allowing the network to be extended, designating the second base station as a remote station, etc ... come up in the assisted menus. I can only get to those options via the manual setup.
I would also note that I called Apple about this problem. After being informed, to my extreme frustration, that Apple does not support manually setup WDS configurations over the phone, the Apple rep told me (in a decidedly dismissive tone) that I should be using the assisted setup process. So Apple has confirmed that this is the way to go ... but Airport Utility doesn't seem to work that way.
Help? Anyone?

How do I restrict wireless network access to specific devices/computers, using an Airport Extreme, when the WPA2 password is able to be found by other devices?

I have set up a wireless network in my office using a couple of Airport Extremes, and, for some reason, our Windows computers are able to view the password of the network. Well, given that we employ teenagers, you can imagine what happens when they all find out the password. We want to restrict network access to only those devices we deem necessary. How do I accomplish this?

SidMed wrote:
We need 18-20 devices to access, all wirelessly.
You can keep using your Apple routers as AP devices.. but get a router running a secure OS as the actual router that controls the network..
If you have 18-20 teens on the network.. then setting quota and restrictions on bandwidth is far more important than time..
Gargoyle on a cheap router can do it.. eg WNDR3800 or the newer W1024ND v2.
Simply turn off the wireless in these devices.. and use the ethernet connection to the airport as WAP.
Honestly you just will never get the security or control using apple domestic routers.
