How do I run diagnostics on an AirPort Extreme

I have an old and possibly slightly ailing MacBook Pro (specs below) and a slightly less old AirPort Extreme (802.11n but not dual-band).
Every once and a while my connection will drop on the router and I'll be unable to find it. However, if I look at the AirPort's status light it says everything is fine. Which it obviously isn't.
However, it never seems to happen when I'm on other wireless networks, though none of those are 802.11n networks, they're all mixed b/g.
It seems happen intermittently, sometimes when I'm not doing anything, sometimes when I'm doing a lot, sometimes when I'm trying to connect to my work's VPN from home... I can't isolate a "It happens when I do this."
Anyone have any tips on how I can figure out where the issue is without replacing the router, hoping it's that and if not starting the new laptop fund?
edit:
It just happened again. This time instead of waiting for my computer to recognize the network I simply selected 'Other Network' and typed in the network's name and password, which connected me immediately.

Ah, that explains it. The Westell (and Motorola) DSL modems are somewhat of a hybrid. They only furnish one IP address, so you have to hook up your AirPort Extreme to "Share a public IP address" if you want to connect more than one device.
Yet, the Westell and Motorola are technically routers because they do furnish NAT service. That's where the double NAT is coming from because when you have the AirPort Extreme setup to Share", it also furnishes NAT service.
The only way that you will able to eliminate the double NAT on your network is configure the Westell in bridge mode only, and then setup the PPPoE service on the AirPort Extreme.
There's no guarantee that this will improve your performance, but it will eliminate the double NAT issue.

How can I open ports on my AirPort Extreme, from WINDOWS?

I have an Airport Extreme as my router, and I have a Windows-based computer. I need to open ports on the router (ironically, it is for my Apple TV).
However, even though I can use the Airport Utility for Windows (latest version 5.5.3), I cannot open ports from the application.
Everywhere I look, I am supposed to have a firewall tab in the Advanced section, but I do not have it. The only tabs that I have in Advanced are:

Is your AirPort Extreme the only router in your network configuration?

How to connect a hard drive on Airport Extreme (second edition)

how to connect a hard drive on Airport Extreme (second edition)? Does it need a special format? It is now fromat on FAT32, but i don't see it ??

The USB port your Mac is high powered. The port on the AirPort Extreme is not.
So, it tends to be borderline as far as its ability to supply sufficient power to a hard drive...even if the hard drive has its own power supply.
Often, users...including me....need to use a powered USB hub when they attach any drive to the USB port on the AirPort Extreme.
You might want to give that a try. Double check to make sure that the drive is formatted in FAT32 as well, since Windows NTFS or exFAT will not work with the AirPort Extreme.
Powering down and restarting the entire network.....modem first, then router, etc.....is something that you would always want to do after any change or addition to a network.

Mmm, generally you don't need to do much port mapping in an extreme. Not sure I understand you. What does the d-link do?

How to extend the range of my Airport Extreme network by adding an Airport Express

How to extend the range of my Airport Extreme network by adding an Airport Express?

You have to make sure that the AirPort Express is in Factory Default Settings. If it is straight out of the box, it is ready to be configured.
The instructions that I will provide are for using AirPort Utility 6.0, which you have.
Locate the Express in the same room as the AirPort Extreme for the configuration. Power it up and allow a full minute for the Express to display a blinking amber light.
Make sure that the wireless is turned on your Mac
Open AirPort Utility 6.0 and look at the small rectangle in the upper left hand corner of the display. It should now read something like "Other AirPort Base Stations (1)"
Click on the rectangle, and then click on the AirPort Express xxxxxx listing
AirPort Utility will take a minute or two to analyze the settings on your network and then suggest that the Express be configured to "Extend" your wireless network.
Edit the Base Station name to your liking, then click Next in the lower right hand corner
Allow a full minute or two let AirPort Utility do its work
When you see Setup Complete, click Done at the lower right of the window.
Now move the AirPort Express to a location that is approximately half way between the AirPort Extreme and the area that needs more wireless coverage.
You should be in business.

How to set up Guest Network, while Airport Extreme is connected to Satellite Receiver

How to set up Guest Network, while Airport Extreme is connected to Satellite Receiver?

Depending on how you have your AirPort Extreme configured to work with the satellite receiver, it may or may not be possible to enable the Guest Network function.
We will need to check some settings on your Mac or PC, but in order to do that, we need to know what operating system you are using on your computer.
If you have a Mac, click the Apple icon in the upper left corner of the computer screen, then click About This Mac. Post back with the OS X Version number that you see there.

How can I configure my first gen Airport extreme?

does anyone know how I can configure my 1st Gen Airport Extreme with my latest Airport Utility? Or is there another way?

A 1st Generation AirPort Extreme is model number A1143. Please check on the bottom of your device to confirm that you have this model number.
A1143 can be configured using the latest version of AirPort Utility in Mountain Lion OS X (10.8.4).
If you don't see model A1143......you do not have a 1st Generation AirPort Extreme. What model number do you see?

How do I install Enabler from the Airport Extreme disk?

Recently I purchased an new Airport Extreme. One of my 3 computers is a 2 GHz Intel Core Duo iMac with 20 inch display (iMac4,1). It is running 802.11g. I wish to enable it for 802.11n. I am confused by a statement about the enabler, which is found at the following link for the AirPort Extreme 802.11n* Enabler for Mac (http://store.apple.com/us/product/D4141ZM/A?fnode=MTY1NDAzOA&mco=MTA4MjgwNzI). The statement is, "Important note: The Enabler is included free with the new AirPort Extreme Base Station with 802.11n. If you purchase a new AirPort Extreme Base Station, you do not need to purchase the Enabler separately." On my iMac, the Network Utility indicates the iMac is not enabled for 802.11n. I have kept the software on the iMac up to date. Thus I assume that somewhere on the disk that came with the Airport Extreme, there is an enabler file I need to access. Where do I find this, and how do I enable the iMac for 802.11n? Thank you.
Sincerely,
Wilson

I am still a bit confused, because the information at the link I gave seems to indicate that a person with my model of computer should be able to use the AirPort Extreme 802.11n* Enabler for Mac.
1. My computer is not a 17 inch 1.83 GHZ. It is a 2.0 GHz Intel Core Duo iMac with a 20 inch display (measured diagonally).
2. The web page (http://store.apple.com/us/product/D4141ZM/A?fnode=MTY1NDAzOA&mco=MTA4MjgwNzI) says check "Before purchasing the 802.11n Enabler software, please check to make sure that your Mac does not already have the 802.11n enabler already installed."
3. It then shows how to use the Network Utility to see whether or not the enabler is installed ("If the section "Model: Wireless Network Adapter," if it says (802.11a/b/g/n), you already have the 802.11n enabler installed. If it says (802.11a/b/g), you do not have the 802.11n enabler installed." My computer lists "802.11a/b/g".
3. Thus I assume that all now I need to do is to install the enabler, which one then can purchase, which one then can do through the Apple Store web page.
4. My issue is that the same web page says I do not need to purchase the enabler if I have already purchased the Airport Extreme base station. ("Important note: The Enabler is included free with the new AirPort Extreme Base Station with 802.11n. If you purchase a new AirPort Extreme Base Station, you do not need to purchase the Enabler separately.")
What have I missed?

How do I configure port forwarding on Airport Extreme via Win 7/64?

Hello all,
I'm trying to forward some ports in order to correct issues with setting up servers for video games, i.e. I can connect but another can't while yet another can connect fine, etc. So far, despite thorough Google searching, I have not been able to find a solution that matches my exact problem.
The specific ports I want to forward are 7777 and 25565. Currently, my connection is through Northstate Communications using an ADSL modem/router (Zhone Model No. 6218-I2-200-0NS) hooked up to an Airport Express + Time Capsule (Model No. A1254, version 7.5.2). As far as I know, the only reason the Airport Extreme is there is for the time capsule, but I don't know for sure whether my computer is actually connecting to the internet through one or through the other. I didn't set it up originally, unfortunately.
I currently can't edit the settings for the Zhone. Supposedly, typing 192.0.0.1 into the address bar of my web browser should open the router configuration utility, but instead it returns "Oops! Google Chrome could not find <address>." I can, however, use the AirPort Utility for Windows to edit all of the AirPort's settings. I have followed the instructions in this YouTube video to forward the port 7777 using the AirPort Utility: http://www.youtube.com/watch?v=OFad6NvddRk but changes I make to Advanced/Port Mapping apparently do not work because www.whatsmyip.org and www.canyouseeme.org report that a test of port 7777 is either timing out or unavailable, respectively.
I am concerned that the IP address automatically provided for me when I create a new port mapping is not the correct IP address since it is 10.x.x.x, which I can't find anywhere in any settings on the computer or online. But, when I type in the IP address I get from www.whatsmyip.org (97.x.x.x) and then go back to edit the setting I created, it has apparently reverted to 10.x.x.x without saving the address I entered.
So, what am I doing wrong? Do I need to change some settings in the Zhone router before it will work, and if so, how can I access it? What is the 10.x.x.x address that the AirPort Utility assigns to new port mappings by default? Since I intend to use Hamachi to host the game server, do I need to use the IP address given to me by that program (5.x.x.x) instead? As far as I can determine, all my drivers are up to date. Any assistance would be much appreciated. Other system specs given below:
CPU: AMD Phenom II X4 945 3.00 GHz
MB: MSI 790FX-GD70 AM3 AMD
RAM: Corsair Dominator 4GB (2 x 2GB) 240-Pin DDR3 SDRAM 1600 (PC3 12800)

Wireless: AZiO AWD102N PCI Wireless Adapter
OS: Windows 7 64-bit
-R

Thanks for your response. I attempted to do that, but I couldn't find any way to access the configuration for the Zhone router. Typing the IP address into my web browser's address bar only resulted in "page could not be found" or "page timed out", etc. I called tech support at Northstate, who likewise suggested that the Zhone router should be set to bridge mode and the AEBS set to router mode since it would be easier for me to configure the AirPort. After wrangling a bit with them over my inability to change any settings for the Zhone, they sent a technician over. He messed around with the Zhone, apparently putting it in bridge mode, and we managed to get the AirPort to work without any double NAT errors. I reset the AirPort and created a new configuration file. Unfortunately, when I went to the Advanced/Port Mapping menu and repeated the original steps to forward port 7777, tests at www.whatsmyip.org still returned "timed out". The technician said he wasn't knowledgable enough about Apple products to assist me any further and suggested I call their tech support or visit the nearest Genius Bar. So that's about it. Any other ideas?

How to connect a Philips fidelio to airport extreme?

I just purchased an Airport Extreme Time capsule. I cannot connect my Philips fidelio AD7000W to the network. There are no WPS button on the Airport Extreme. There is a WPS printer connection option in the Aiport app menu option but nothing for sound system. Anyone knows how to make the connection ?

Instructions on how to connect the Fidelio to a non-WPS supported router is covered in the User Guide starting on page 13. On step 4 you would enter the specifics for your wireless network. That would be the network name, the wireless security type & wireless password. You will also want to choose the DHCP mode as enabled for these speakers.

How do I open ports on my airport extreme and assign a fixed IP Address for a device connected to my network?

I recently had a security system installed in my house. One of the features is an EPAD which enables me to have a virtual keypad on my iphone, and computer to operate the alarm system. The technician was not familiar with Mac's and Airports. How do I open port 80 to 80 in my airport and assign a fixed IP address for the EPAD? Apparently this is what is needed to make this work.

There are three ranges of "strictly local" IP addresses reserved for local Network use:
192.168.xxx.yyy
172.16.xxx.yyy
10.xxx.yyy.zzz
What your Router does for you is to act as your agent on the Internet.Your requests are packaged up and forwarded on your behalf, and only when a response is expected is the response returned to your local IP address.
Directing Network Traffic to a Specific Computer on Your
Network (Port Mapping)
AirPort Extreme uses Network Address Translation (NAT) to share a single IP address with the computers that join the AirPort Extreme network. To provide Internet access to several computers with one IP address, NAT assigns private IP addresses to each computer on the AirPort Extreme network, and then matches these addresses with port numbers. The wireless device creates a port-to-private IP address table entry when a computer on your AirPort (private) network sends a request for information to the Internet.
If you’re using a web, AppleShare, or FTP server on your AirPort Extreme network, other computers initiate communication with your server. Because the Apple wireless device has no table entries for these requests, it has no way of directing the information to the appropriate computer on your AirPort network.
To ensure that requests are properly routed to your web, AppleShare, or FTP server, you need to establish a permanent IP address for your server and provide inbound port mapping information to your Apple wireless device.
To set up inbound port mapping:
1) Open AirPort Utility, select your wireless device, and then choose Base Station > Manual Setup, or double-click the device icon to open its configuration in a separate window. Enter the password if necessary.
2) Click the Advanced button, and then click Port Mapping.
3) Click the Add button and choose a service, such as Personal File Sharing, from the Service pop-up menu.

How many devices can I link to AirPort Extreme?

How many devices can I linked to an AirPort Extreme. It seems that whenever I have more than 3 devices (all iPhone and iPad), I can't link the fourth one.

The answer will depend on the type of modem that you have connected to the AirPort Extreme.
If the AirPort Extreme is connected to a simple modem, then it will act as the main router for your network. In that case, the AirPort Extreme will support up to 50 wireless devices and 150 wired Ethernet devices.
If the AirPort Extreme is connected to a modem/router combination device....also known as a gateway.....then it is your modem/router that determines the number of devices that can connect to the network.
If you are unsure of what type of product you might have, post back with the make and model number of the device that you call your "modem". (We do not need a serial number for the device).

How do I Setup USB HDD on Airport EXTREME TIME CAPSULE? USB HDD Not showing up

How can I get the HDD to work with my airport extreme? Does it need formatted a specific way for mac? Are there certain hdd types that work best with the I have a WD usb hard drive which doesn't show up when connected to airport extreme. I'm trying to setup time capsule, but Having no luck. I'm new to the Imac.
Message was edited by: clower80

A couple of pointers.
The hard drive must be specifically formatted in Mac OS Extended (Journaled) to work with the AirPort Extreme's USB port. Check the documentation that came with the drive to find out how it is formatted at the present time.....it is likely formatted to work with Windows, which is not compatible with the AirPort Extreme.
Unfortunately, even if the drive is formatted correctly, Apple does not officially support Time Machine backups to a drive at the USB port of the AirPort Extreme, so that will be the next hurdle to deal with.
Some users actually do seem to be able to make this work, but overall, it is not a reliable method to backup your data if it is important to you.

How do I access the firewall in Airport Extreme?

Hello, this may be a very stupid question, but how do I access the firewall in my brand new Airport Extreme? According to the Apple specifications, it contains a built-in firewall, yet I cannot find any mention of this when using Airport Utility to set up the Extreme.
I am using the Extreme connected directly to a modem on the UK BT Infinity fibre optic broadband system using PPoE. The modem is not a combined modem/router, it is a modem only, hence using the Extreme to set up my network, which I have to say (apart from this one question) was incredibly easy. The wireless system is protected as WPA2 Personal.
Router mode is "DHCP and NAT" and "Enable NAT port mapping protocol" is ticked as on - is that it? Is that all I have do to have the firewall on? Should I also have "Enable Default Host" ticked as well? Apologies if this is a silly question - I do not understand firewall set-ups.
I am using 10.7.3 Lion on my MacBook Pro and have a Mac Mini on Snow Leopard connected to the Extreme, plus the usual assortment of iPads, iPhones, Apple TV and iPod Touch.

I don't use this setting, so can't offer much assistance, but do know that your computer is exposed to the Internet, so it will receive all inbound traffic.
Normally, a typical use of Default Host would be to setup a game console to allow online gaming when NAT settings otherwise would not allow communications to occur.
You might want to start a new post for your question...but to get informed responses....you will need to state what you are trying to do. what steps you have performed, etc.
