IP Configuration issue with Airport Extreme

When configuring my Airport Extreme to use the AT&T DSL internet connection, an IP Configuration conflict is reported. My IP address is shown as in use by the Ethernet ID - DHCP Server. As a consequence, the Airport is not reporting an IP address to allow an internet connection. Here is the actual message:
192.168.1.64 in use by d8:a2:5e:7a:6e:35, DHCP Server 192.168.1.254
Hard re-starting the AIrport Extreme does not shake this configuration error.
I am now connecting successfully to the internet with an ethernet connection to the AT&T modem.
Thanks.

Check out this thread for some interesting items. The same instructions work for several users...but not another.
Re: AirPort Extreme Set Up Issue
AT&T wants this modem and router to work using DHCP - Bridge mode.
Not sure what you mean here.
This modem will not work correctly with an AirPort Extreme unless you put the modem in Bridge Mode or PPP is on the Router and then configure the AirPort Extreme to provide the PPPoE service.
I pulled out my old 2210 to test and confirm. Everything works just fine the way that AT&T recommends.
I think you will have nothing but headaches if you try to configure the modem for PPP is on the modem. Even if you can get the DHCP issues ironed out, a Double NAT error remains.

Issues with Airport Extreme and yosemite?

I have a Airport Extreme (7.6.2) connected to my wireless network as a client. Connected to this I have a sound system (HK SoundSticks II) and a Lexmark (CS510de) printer via ethernet.
I have had no issues with this configuration on Mavericks (and previous); however, since I have upgraded to Yosemite, my airplay sound will randomly lock up and my printer drops offline after the first print to it. I can get these devices back by cycling my Airport Extreme.
Anyone else seeing these issues?

Check the cabling to the Base Station - make sure the modem is plugged into the Base Station's ethernet WAN port (ie the port labelled with the "circle of dots" icon).
With the modem cabled to the Base Station - pull power to both for five minutes or so. Then plug the modem into power and wait a minute. Then plug the Base Station into power and wait a minute. Then try internet access again.
If that still doesn't work:
- on the Mac which can successfully connect to the internet when cabled directly to the modem, tell us what settings are found in System Preferences->Network->Show ethernet built in->PPPoE tab, and under the TCP/IP tab.
- from either a PC or the Mac connected to the Base Station, run the Airport Admin Utility, select the name of your base station, click Configure, click on the Internet tab. Tell us what settings are found under that tab.

Speed or Performance Issue with Airport Extreme 802.11n

Background:
Router 1: Linksys Wireless G 2.4GHz Router WRT54G (have been using for 1.5 years)
Router 2: Airport Extreme 802.11n Base Station Model: A1143 (just arrived)
Macs: Intel MacBook Pro & MacBook both Newtwork Adapters upgraded to 802.11 a/b/g/n and verified via "Netwrok Utility". The Netwrok Utility also displays the link speed at 54 mb under interface info. when the Linksys G router is selected and the link speed at 144 mb when the airport extreme n is selected.
Observation & Issue:
Currently, for testing both network routers have been used seperatly (connected directly via the cable modem) and speeds for each latop verified via http://www.speakeasy.net/speedtest/ and normal "human" usage web surfing observations via Safari. Results below:
1. When using the Linksys G router both the MacBook and MacBook Pro appear to be performing well and responsive with little or no wait on graphically/media intense sites such as apple.com
The speakeast.net/speedtest/ (using the NYC hub close by) downoad test displays 8MB to 10MB speeds
2. On the otherhand, when using the Airpot extreme both the MacBook and MacBook Pro appear to be performing slower than usual with higher waits for image and page downloads.
In addition, the speakeast.net/speedtest/ (using the NYC hub close by) downoad test displays 2MB to 3MB speeds. Lower than what we experienced using the older router.
Request for advide or help:
1) Is this normal? Assuming it is not, what esle can I look at that can help me determine the root cause. The Airport Utility does not offer much assistance in this matter.
2) Thus far I have opted to revert back to my Linksys g router. However, before returning the product... any other adivce on a potential miss in the configuration or setup would be of great help.
3) Other's experiencing the same?
MacBook Intel & MacBook Pro Intel Mac OS X (10.4.8) SUing Comcast Cable Modem

Contacted Apple Support (have an AppleCare account) tonight and the issue has been resolved with the caveat that I cannot have a mixed (g & n) radio mode on the same airport extreme base without significant loss of performance. These are the steps I was walked through to resolve my particular case:
1) Verify that your hardware is indeed upgraded to use n (see steps in my original post)
2) Open the AirPort Utility (new program that was installed from the install disc under applications/utility)
3) Click on the Airport Extreme image on the right hand column to open the Airport Extreme settings
4) Select the "Wireless" tab, then "Radio Mode" drop down and select 802.11n only (5 GHz)
5) Select Update to apply new settings.
Results:
When running the speakeasy.net/speedtest I am seeing results that are indeed better. However, the test shows that the top speed lowers a bit and jumps back up unlike when I am on my old g router, which does not have such a jump.
This test is not perfect but a good gauge. If anyone has any other ideas to test performance more accurately, please do let me know.
Note: Only n enabled devices now work with the n router. I will keep my old g router as a backup and for my work pc laptop.
Hope the above helps and thanks.

Several PC and Mac connectivity issues with Airport Extreme Base Station

Hello,
This is not all necessarily airport base station related, but there is some crossover, so I'm posting all of these issues...
Here is the laundry list of things that I can't make work in a home network that contains a PC w/ XP Home, MacBook 1.83 w/ 10.4.7, and Airport Extreme Base Station w/ Modem.
1. Can't see the PC from the Mac.
a. "Connect to server -> Browse" does not find the PC
b. "ipconfig" on PC provides valid looking IP address
c. ping from mac to PC IP address times out
d. Firewall on XP is disabled via control panel
b. Windows file and printer sharing is enabled
2. Can't see mac from PC
a. Windows file sharing enabled on mac
b. Firewall on mac disabled
c. I used \\MacIPAddr\shortusername
d. ping times out
3. Using dial-up to access internet, how do i tell airport to dial using PC?
a. this feature is working fine from mac
b. If already connected (via instruction from mac), can surf the internet fine from PC
c. Is this even possible from the PC?
4. Can't see printer connected to base station from PC
a. See it fine from mac
b. How do i "find" the printer on the PC?
c. Is Bonjour required for this? (I don't have it on the PC yet)
5. Can't see a "shared" printer on the PC from the mac
a. printer is connected directly to PC
b. Mac's add printer wizardry looks like it may "see" the printer, but then it asks for username and password for PC. This is XP home, with no usernames or passwords. Single user. Nothing seems to work in the credentials pop-up dialog.
Any suggestions on any of these issues is very welcome.
Thanks

Is the PC running any kind of internet security or firewall software?

Issues with Airport Extreme and Time Machine

I have a Airport Extreme that is connected to a cable modem, that airport extreme is then hardwired connected to a time machine.
Recently, I have had trouble connecting wirelessly to the airport extreme. Even more troubling is that I can no longer can connect via ethernet to the time machine directly. In other words, the only way I can connect is by directly connecting to the airport extreme.
Any help would be great. Oh I have a MBP with the latest updates and a MB that is not connecting to the time machine or wireless to the extreme

I have used the following for about two years.

You probably know, that's "iffy" and +*not supported by Apple.+* See the Using Time Machine with a USB drive connected to an Airport Extreme *User Tip,* also at the top of this forum.
To get around this issue, I have switched off the Time Machine, and am only turning on once a week or so, to grab any changes or additions I've made. I've been doing this for about 6 months now with no problems.
Now whenever I do this, (It should only be backing up an album or two from iTunes,) it tries to back up my whole system again. EVERY TIME. It did not do this before.
If you go too long between backups, Time Machine will do a new, full backup. And once it decides to do that, it will keep trying until it succeeds. There are some other possibilities as well. See #D2 in the Using Time Machine with a USB drive connected to an Airport Extreme *User Tip,* also at the top of the +Time Machine+ forum.
If none of those seem to explain it, see #A1 there; download the TM Buddy widget, copy and post the messages here.
Why are you only backing-up once a week? Time Machine was designed to back up changes hourly, as long as your Mac is awake and the TC is in range. It will protect you best that way, and unless there's a problem, those backups will usually be very quick.
But if you're only going to back up once a week or so, then Time Machine is not the best app for you. See Kappy's post on Basic Backup, complete with links to the web sites of each product.

Ongoing wireless issues with Airport Extreme + Express

We have 5 macs in our household. 2 laptops, a desktop, a Macbook Air and a Macbook pro. We have dsl and had a Linksys router. All of us were able to use the internet fine: Airport bar always showed full bars (we did have some slowed response when everyone was on at once but it never posed a major inconvenience). However, the Macbook air had problems from the beginning: dropped connections, choppy video with stalls, buffering taking forever. The Air is the newest of all the computers purchased in April. I went to the Mac store and they suggested purchasing the Airport Extreme AND the Express to ramp up everything both in terms of signal strength and range. Installation was fairly easy and I added the Express to the Extreme network. Now even when standing next to the Extreme base station I get only 2 bars (the little dot at the bottom and one bar above it). I notice no increase in speed. There is worse reception on the Macbook Air belonging to my daughter...she has given up on videos and uses her sisters' laptops to download music to her her iPod. I have cleared caches, updated all computers, reset the modem and router, reset the dhcp lease...nothing works. How is it I had better connection with a NON Mac product?(Prior to buying the new Airports I purchased a Ralink network adapter for my daughter and myself and we had better performance with that ...at $17).As all Mac computers are experiencing the same low performance except for the Macbook Air as noted above it cannot be a hardware issue. Is there something else to be done with theAirports? Please advise.

1. Try switching to a different channel.
2. Try System Preferences>Network>Advanced>DNS
Click on the + and insert:
208.67.222.222
208.67.220.220
click OK, then click Apply.
You can do that on each Mac.

Port 80 issue with Airport Extreme.

Hosting a website on an iMac via an Airport Extreme 11n (AE 11n) connected to a standard Time Warner cable modem. Recently purchased the AE 11n. Using DHCP/NAT via AE 11n. Use DynDNS for Dynamic IP addressing. Once I added the AE 11n, lost web-hosting. Just recently caught this. DynDNS updater was showing OK when testing iMac ip address as the Ethernet IP address test. Firewall set to allow all connectings on iMac. Default config on AE 11n. DynDNS query on the AE 11n ip address was showing refused. Same query on iMac ip showed timed-out. iMac port scan showed 80 as open. Configuring port mapping on AE 11n didn't help. Once I removed the only port mapping (Personal Web Hosting) from AE 11n and just selected Enable Default host at: set to the iMac ip address, everything worked again. Website was seen on iMac by everyone. DynDNS query shows AE 11n ip address open again for port 80. iMac ip test with same DynDNS tool showed timed-out. The reason I'm writing this is that all website viewing worked when I first hooked up and configured the AE 11n. It was the internal web-hosting that failed, but no visible signs as I was able to see the website in question on the iMac on the internal network, but no one outside the network could see it till I enabled default host at in the Internet:NAT: settings. Honestly not sure if this help anyone, makes sense to me know as enabling default allows that one computer to be the default port to look at for any port forwarding via the AE 11n or that is my thought. Hope this rambling will help someone.

PS., Also had to set DynDNS updater to Web-based IP detection using the ip address of the AE 11n in the Interface setting.

Have the issues with airport extreme 7.4.1 been resolved yet?

Hey. I updated to 7.4.1 from prior version when prompted. One i did so, my macbook pro and my iphones could not stay connected at all. I spent well over 2 hours with soft adn hart resets. Oddly my toshiba was uneffected. When i called the help desk i was on the phone with them an hour too, doing all the same stuff. They finally had be switch from automatic as my channel setting to 3... Anyway, after days of annoying dropped connections, i rolled back to the earlier version and all is perfect with the world. I keep getting asked to upgrade. Does anyone know if the issues that were reported have been resolved?

Airport Extreme 7.4.2 didn't fix it here. iTunes 8.2 still cuts out.

Heat issue with airport extreme

The top gets hot but the sides stay only warm. The temperature on the top is around 110 F. The unit works very well and I have had no problem with it.I'm worried the high operating temperature will shorten its life.

Too hot to touch would be cause for concern, but 110° isn't abnormal.
From p. 35 of the Airport Extreme Setup Guide:
About Operating and Storage Temperatures
When you are using your AirPort Extreme, it is normal for the case to get warm. The AirPort Extreme case functions as a cooling surface that transfers heat from inside the unit to the cooler air outside.
The case itself is a heat sink, so keep the top clear of other "stuff" (including dust).

Configure protocol with airport extreme base station

Need powerbook g3 wireless internet compatible password. roamabout 802.11b cabletron card does not have wpa password option. There does not appear to be a compatible encryption type to use airport extreme base station with this card.

...should I have AirPort on my iMac turned off or on...
Since you are connected via Ethernet you would turn AirPort off.
Does the connection automatically default to Ethernet, even if AirPort is set "on," because presumably Ethernet is faster.
No. It gives priority based on how they are ordered in the list of network connections.

Issues with Airport Extreme/Express/PS3 network

I have searched and searched and cannot find the answer to my problem. In my house I have an Airport Extreme, a Linksys switch, and an Airport Express all creating my wireless/ethernet network in the house. Since day one, my PS3 joined our network and I have been able to get online, no problems. Recently though I have decided to attempt to get the horribly difficult NAT type 2 with no success.
Right not I have the Extreme acting as the WDS main and the Express (which delivers perfect connection to the PS3) acting as a WDS remote in Bridge mode. The Extreme is sharing a public IP and I have a DHCP reservation for my PS3 (using the default 10.0.1.253 IP) along with all the PS3 necessary ports forwarded. I have also set up the Extreme to set my PS3 as the default NAT host.
My problem is that I get a "Conflicting DHCP Range" error. I also get a lot of warning messages every now and then saying "10.0.1.x is already in use by *MAC address* 10.0.1.1". I still can get on the internet with my computers and PS3 but I have noticed that signing onto PS network works very rarely.
I absolutely cannot make sense of this. I also don't have my NAT 2 so can anyone help me.

Is the PS3 connected to the express over WiFi or plugged into the ethernet port on the express or both?
You should not need forward ports and set the default NAT host. Just setting the default NAT host will forward all traffic that is not sent to another host to the PS3. I would recommend forwarding ports instead of using default host for security reasons.
You could also try setting static IP info in the PS3.

Major issues with Airport Extreme and Blu Ray Players

I've been working with this for several days now, and am at the end of my rope. Hopefully someone has some answers.
I've got the original 802.11n Airport Extreme. I've had it since it was released, and have had no real problems up until now.
At the beginning of May I got a new TV with a Samsung Blu Ray player. Model BD-C6500. The first one died halfway through our first movie, and I took it back. The second one worked fine for a few weeks, and then all of a sudden told me that it couldn't connect to the network.
This was about the time that we had a power outage, but all devices were hooked to surge protectors, so I'm guessing that it was just coincidence, but I thought I'd put that here just in case.
Well, the Blu Ray player was a real puzzle. I would try to connect, and it would connect, but not get an IP address. I'd do it again, and then it would but couldn't get past the router. I'd do it one more time, and it would work for a while, and we could watch Netflix. Then it would stop working again.
I finally took it back and exchanged it, thinking that it had some problems. The new one did the exact same thing! Brand new C6500 won't connect, or can't get IP, or can't get past the router, but sometimes works.
Frustrated, I went back and exchanged it for an LG, model BD570. It logged onto the wireless right away, downloaded the firmware update, and worked perfectly on Netflix and Pandora. Success! Until this morning. Now it's doing the same thing, where it can connect, but can't get past the router. No internet connection.
I've got two laptops, a PowerMac, two iPhones, and an TV running on this router with no problems. Settings are mostly standard, with security set for WPA/WPA 2 Personal, with a 13 digit password. I've tried both DHCP and Static IPs for the BD Player. I've used both the router address along with outside servers for the DNS. I've removed password security. I've tried WEP. I've changed the multicast rate. I've done a full reset of the router.
Any help would be appreciated. Wired access is not an option in this location, and I don't want to drop $100 on an Aiport Express if I can help it.

**My Airport Express access point firewall needed to be set to "HOST", then everything worked wonderfully.**
Before the "HOST" firewall change my symptoms were as follows:
The wireless setup process would work sometimes, other times not (not result in a successful connection). Also, when it did work, it would be lost when the c6500 shut off.

Mac Mini Bluetooth Connections Issues with Airport Extreme

Hi,
The issue I'm having is my apple bluetooth devices will not connect to my mac mini. This problem started a few weeks ago and i have narrowed it down to my Airport Extreme which is right next to my Mac Mini. I have tried adjusting the channels and removing the Wide channel option on the Airport Extreme this has helped I can use my magic pad (not really up to par but it works). When I disconnect my Airport all my bluetooth devices work great. Moving my airport extreme isn't an option without a large amount of work putting in a new cable outlet. I don't know what changed from a few weeks ago as the devices have always been within inches of each other and worked fine.
I was trying to find a way to disable the 2.4 band on the airport extreme but this for as far as i know can't be done. I'm running out of ideas on what to do next any help would be great.

Are you sure it's not the monitor? Monitors have been known to do this.
Try changing the broadcast channel on the AEX using the Airport Utility.

Issue with Airport Extreme and 100mbps connection

Hi,
I have just upgraded my connection to 100mbps. Using a ARRIS TM 502G cable modem and the Airport Extreme I am able to get the 100mbps connection via either ethernet or wifi on my main MacBook Pro. However, the Mac Mini in the loungeroom (10 metres away from the Airport Extreme) is only getting speeds of around 25mbps.
Does anyone know why this might be or what I can do to resolve it?
Thanks,
Matt

The Mini was connecting at 20 - 25mbps via wifi.
The Macbook Pro was connecting at 80 - 90mbps via wifi (when in same room as Airport Extreme) and getting anywhere from 80 to 140mbps via a wired connection.
I've moved the Airport Extreme so it has the best "line of sight" to the Mini, and also disconnected a cordless phone I had in the room which was interfering with the signal.
After these changes I'm able to get speeds of 30 - 45mbps on the mini and similar speeds on my macbook if I move it next to the mini. It looks as though that's the best I'm going to be able to get without hard wiring the mini - which is disappointing ... unless of course you clever people have any other ideas?

Discovery issues with airport extreme and issues with airport utility

I lost about 3 hours with connection issues while trying to add a second airport express. The airport Utility couldn't find any of the units anymore. After aging a couple of years and checking lots of forums (many suffered the same problems) I found this link
http://support.apple.com/kb/HT1406#
Which seemed to help me reset the units and find them again. Though I can't be certain if it was just luck, the airport utility and detection and resetting of the express and extreme seemed solved.
I would add that this is an area that should be looked at by apple. It is not the first time that I have problems with the airport utility or the extreme.

Check the cabling to the Base Station - make sure the modem is plugged into the Base Station's ethernet WAN port (ie the port labelled with the "circle of dots" icon).
With the modem cabled to the Base Station - pull power to both for five minutes or so. Then plug the modem into power and wait a minute. Then plug the Base Station into power and wait a minute. Then try internet access again.
If that still doesn't work:
- on the Mac which can successfully connect to the internet when cabled directly to the modem, tell us what settings are found in System Preferences->Network->Show ethernet built in->PPPoE tab, and under the TCP/IP tab.
- from either a PC or the Mac connected to the Base Station, run the Airport Admin Utility, select the name of your base station, click Configure, click on the Internet tab. Tell us what settings are found under that tab.
