How to configure Airport Extreme SubNet?

My landlord has Internet access for his wired and wireless devices using an Airport Extreme with a wireless password he won't give me. He wants to keep his network private but said I could wire my own Airport Extreme to one of his Extreme's LAN ports if I could show him that I can't see his devices and he can't see mine.
His Extreme is configured to Share A Public IP Address. I'm worried that if I configure my Extreme like his that we'll have a DHCP or NAT conflict but I don't know how else to do it even though I read through Apple's document called Apple Airport Networks.
Can you help? Remember, we don't want to be able to see each other's devices. Thanks

Connect the Ethernet cable from one of the LAN <-> ports on the landlord's Airport to the WAN port on your Airport Extreme.
You must setup your AirPort Extreme to "Share a public IP address" as well and then assign a different DHCP range for your AirPort.
That will place your AirPort on a separate subnet, so you will not be able to "see" his network devices and he will not be able to "see" yours. This is not really "security" at all, but if both of you are willing, it can work.
Unfortunately, this will create what is known as a Double NAT error on your portion of the network. This is usually not too serious of an error on a simple network, but it will slow down your network communications and browsing a bit. You may...or may not...notice this.
However, Double NAT will cause some serious issues if you plan to use any kind of online gaming console. You will not be able to play interactively on the Internet when it is configured this way.
Setup is relatively straightforward for this, but you must use a Manual Setup option to configure your AirPort Extreme. AirPort Utility in Lion 10.7.3 will not work. You will need to download additional software to configure your Airport to work the way that you want.
Post back if you need a few more tips on getting this set up.

How to configure airport extreme to work with Actiontec gt701d modem

I have been trying to set up a new Actiontec modem to work with a new Airport Extreme with no luck. I don't know what the right settings are to get it to work correctly. So far the only way I have been able to get the two to work together is to have the AE connect with ethernet and bridge mode. However with this configuration I can't setup a guest network which I would like to be able to do. I have read some past posts and have tried other configurations but end up either losing internet connection or getting a very slow connection. If anyone has some idea how to get this modem to work with the AE i would really appreciate some advice
Thank you

Welcome to the discussion area, Meagan!
The Actiontec "modem" that you mention is really a gateway...a combination modem/router, so with this device and the AirPort Extreme, you have two routers on the network.
Whenever you have two routers on a network, the first router must be configured to handle the main routing chores and any other routers must be configured in Bridge Mode to function correctly. So, Bridge Mode is the correct setting for the AirPort Extreme when used with the Actiontec gt701d gateway.
In order for the AirPort Extreme to provide a Guest Network, it must be configured as the "main" router on a network. This won't be possible unless you can re-configure the Actiontec device to act as a simple modem, not a router. You might want to check with Actiontec support to see whether this might be possible.

How to configure Airport Extreme to work with Spotify

Issue: Spotify no longer syncs Spotify files to my iMac or my iPhone despite me being a premium member. I've never had an issue with this until this past week. I can't see anything that has changed but I must be missing something. Anyhow...I'm posting this here because I need assistance with my Airport Extreme configuration (not Spotify).
According to Spotify, I am to configure my (Airport Extreme, latest gen) router to allow the following:
The following IP ranges should be open on port 4070:
78.31.8.0/21
193.182.8.0/21
The number 21 is the prefix length.
I've assigned the static IP to my iMac and my iPhone. I've also forwarded port 4070 (Public & Private UDP and TCP) to my iMac's static IP. I also tried it on my iPhone. What I don't know about is how to open the IP Range on that port as stated above.
Any idea where this can be done? Thanks!

How to configure Airport Extreme AFP disk sharing to host multiple users' home-directories (Lion, using autofs)

I have this working, but only by completely bypassing access control, using guest access with read+write permissions.
Do I need to buy Lion Server, to do this. All my past unix/linux experience says Lion Server should _not_ be necessary.
This seems like a simple & obvious setup objective, but it is proving to be harder than I would imagine.
Setup:
multiple users, sharing two mac mini's running OSX Lion
connected to an Airport Extreme (4th gen) with a USB disk shared (either via disk password, AEBS password, or using AEBS user's passwords).
After much experimentation and web research, I finally have managed to get the mini's to auto mount the Airport Extreme's AFP shared USB disk. Well almost... It only works if, on the Airport, I set the guest access permissions to read+write and select the "Secure Shared Disks" method to "With disk password" or "with Airport Extreme password". In other words, it only works if I essentially bypass/disable access control by using the guest authentication mechanism to the AFP shared disk.
On the Lion side of this, I am automounting the users directories via "autofs". The config files for this are
/etc/auto_master:
# Automounter master map
+auto_master            # Use directory service
/net                    -hosts          -nobrowse,hidefromfinder,nosuid
/home                   auto_home       -nobrowse,hidefromfinder
/Network/Servers        -fstab
/-                      -static
/-                      auto_afp
/etc/auto_afp:
# Automounter AFP master map
# https://discussions.apple.com/thread/3336384?start=0&tstart=0
/afp/users -fstype=afp afp://;AUTH=No%20User%[email protected]/Users/
Then, after rebooting and verifying read+write access to the /afp/users directories, I change each user's home directory: In System Preferences > System > Users & Groups, I right-click over the users to access the Advanced Options, changing the Home directory field to point at the AFP-mounted /afp/users/Users/* home directories.
I experimented with alternate UAM specifications, as well as both OSX and AESB users & passwords. Using guest access is the only thing that has worked.
Any pointers would be appreciated...

Based on lots more experimentation which confirms the information in a parallel discussion (cf. Automount share as non ROOT or SYSTEM user! https://discussions.apple.com/thread/3221944), I have concluded that the Lion 10.7.2 implementation of AutoFS mechanism is broken. I submitted a bug report via apple.com/feedback.
Work arounds..?
Earlier I wondered if installing Lion OSX Server was necessary. The more I contemplate this, the more I am convinced it _should_not_ be necessary. The client-server architecture is clear: my mac's are the file-server client's and the Airport Extreme is supposed to act as the file server. The only thing instaling Lion Server would do (besides enriching Apple.com) is enable me to configure one of the mac's as the file server. This would require it to be "always on" (thus enriching my electric utility as wel). Okay, an additional benefit would be configuring software RAID disks attached to the Lion server, but Time Machine has worked fine for me in the past, backing up to disks mounted on the Airport Extreme.
One solution is to create a disk partition for each user and instruct each user to connect / authenticate to the Airport Extreme AFP share at login. The multiplicity of partitions is necessary since the first user to mount the AFP share, takes ownership of it, blocking other users from accessing that disk partition. A user can "steal" ownership by reconnecting, but this will leave the other user's applications & open files dangling.
This disfunctional situation really *****. Before instaling Lion, I put a 64 GB SSD (solid state disk) in each of our mac's. I did this expecting to easily configure the /Users/* data on external networked storage. I'm having a dejavu "Bill Gates"-ware moment; problems like this were why I abandoned Windoz.
I will make a few more experiments using the depreciated /etc/fstab mechanism. Maybe that will bypass the broken-ness of AutoFS...? Alternately, I guess I could also try to run Kerberos authentication to bypass whatever is broken in AutoFS, but that would require a running a Kerberos daemon somewhere. Possibly I could configure a Kerberos service to run on both my mac's (without installing Apple's Lion Server)...?
Stay tuned...

How to configure Airport Extreme to connect switch?

Hi,
I have an Airport Extreme (3rd generation) on firmware 7.4.2 and it is connected to the WAN to a Time Warner (Motorola) cable modem. I am able to establish a wireless LAN for the home. However, I also have wall ports (ethernet) throughout the home that are connected to a Linksys SD2008 switch. I am hoping to also connect the wall ports through the AEB so that wired computers can get onto the LAN and the Internet. I have checked that I get an IP from the Ethernet ports from the AEB but when I connect that to the switch, however, I do not seem to be able to get an IP on the ports on the switch itself (i.e. the wall ports do not assign any IP, just a self assigned IP address.)
Does anyone know if it is possible to connect a Linksys SD2008 switch directly to AEB (acting as a router)? Thanks.

Suggest that you do some simple "tests" before trying to configure the entire setup.
First, connect a laptop using a short, spare Ethernet cable to one of the LAN <-> ports on the AirPort Extreme and make sure that you can get an Internet connection this way. If you can, you know that the LAN port on the AirPort is working correctly.
Then, connect the same short Ethernet cable to the switch and connect another spare Ethernet cable to the laptop. Make sure that you can get an Internet connection that way.
If you can, then you know that the switch is functioning correctly and you can start to troubleshoot the wiring around the house. If you cannot get an Internet connection, that obviously means that the switch is not functioning correctly.
Having wired many networks, I can say that the problems are almost always in the wiring...a bad cable or a bad Ethernet plug on either end. Take it one step at a time working out from the AirPort Extreme and test each connection, then add another device or cable and test, and then another, etc.

How to configure airport extreme (n) for 1G network?

the network is connected, but only at 100.
the setup is:
Modem Thomson (dont really need it at 1000, my cable bandwidth is only 5Mb) -->
Airport Extreme (n) -->
Macmini C2D 2G and Imac 20" 2G (not C2D, the older one)
Both running 10.4.10 for intel, both have airport utility installed.
thanks!

i still got nothing, i managed using cocktail to make the line 1G/half duplex, the line was active but the computer got no valid ip address from the airport extreme and could not no connect to it in any way.
so...what else to do? i bought the cables (cat 7) becuse i've been told the airport extreme will work at 1G without any problems, but all i get are problems.

HOW DO I CONFIGURE AIRPORT EXTREME TO ENABLE HP EPRINT

HOW DO I CONFIGURE AIRPORT EXTREME TO ENABLE HP EPRINT

Thank you. Before seeing your message, I uninstalled the printer and reinstalled it on my Airport Extreme with WIFI protected setup using the PIN provided by the printer. Next I followed instructions from HP saying I should disable the eprint on the printer and epring on the embedded web server should be turned off. I did both and went about my work until I saw your email. Upon seeing your message, I went to the HP OfficeJet 6700 Premium printer and enabled web services, then went to the console of nearby MacMini, clicked on the printer icon in the dock, clicked "settings" and clicked "show printer webpage" and the on the printer webpage, I went to "eprint" tab, turned it on and for the first time EVER, I heard the connecting chime and saw a green check mark on the web instead of a red x. I returned to printer console, answered the questions and printed the instrucitons, logged into HPeprint center through Safari and changed my password for this printer on the HP ePrint center using the code receive on the instruction page. Everything looks good to go.
Thanks for the advice on the caps. I really did not intend to send the question at all. Glad I did.

How to make Mac OS X Server auto-configure Airport Extreme port-mapping

Mac OS X Server can automatically configure AirPort Extreme to make services such as iChat, Mail, Web, and VPN accessible: http://www.apple.com/server/macosx/features/networking-vpn.html
I presume this configuration generally takes place during a fresh installation of the server.
Is there any way to re-run this process post-installation?

That page talks about Snow Leopard's Networking abilities, not Leopards.
Off hand, I don't know whether what you describe is a new feature in Snow Leopard or not, but I've never seen Leopard do it (and, to be honest, wouldn't want to).
In either case, it's basically just Bonjour telling the router to configure port forwarding. Given that, I'd start by enabling mod_bonjour in Apache:
#LoadModule bonjour_module libexec/apache2/mod_bonjour.so
but I don't know how other processes are doing it.

How far does airport extremes range go

how far does airport extremes range go

Apple says up to 300 feet or so, but since tests like this are performed in a very large room with no walls, the specification won't mean much to most of us in the real world.
Bottom line is that it is not possible to make a good guess about distance capabilities in a home without knowing the number of walls and or ceilings the signal must pass through.
(A typicall wall of sheetrock and 2 by 4s will absorb on average about 15-20% of the signal and a ceiling absorbs more because it is thicker).
As a very rough guide...if the signal from the wireless router must pass through 4-5 walls, or a ceiling and 2-3 walls, then there won't be much of it left by the time it reaches a computer or other wireless device.

How to configure Airport Express N router and Netgear G router with Extreme

I have a primary Netgear G router (WRT54G) connected to my cable modem box. I have an Airport Express N router streaming music in another room and also extending the wireless network.
I am planning to demote the Netgear router as a switch + wireless network extender connected to my home theater setup (dish+apple tv+ps3) and purchase a new dual band Airport Extreme connected to the cable box and acting as the main router.
My question is if its possible for the N devices to still use N network while the G devices not demoting the whole wireless network to G? That's the reason why I want the Extreme. If yes, how to go about doing it? If not, I will just buy a cheap switch and use that for the Home theater and leave the current setup alone. Anyone who has a similar network, please advice. Thanks!

My question is if its possible for the N devices to still use N network while the G devices not demoting the whole wireless network to G?
Yes. To do so, you would need to connect the Netgear to the new 802.11n AirPort Extreme Base Station (AEBSn) by Ethernet, and then, reconfigure it as a bridge (disable both its NAT & DHCP functions).
In this configuration, the AEBSn & AXn can provide the 802.11n network and the Netgear can provide the 802.11g network.

How configure Airport Extreme Base Station M8440

Hi, my problem is:
I bought this Airport Extreme Base Station and I´m having lots of problems trying to get it configured, I have tried with the Mac's Airport Utility, with the Windows version too, also with the AirPort Extreme Admin Utility v3.2 on Windows but nothing. This Airport was working but I wanted to change the SSID and the access key but I just can not, I want to know what can I do to configuring it as a normal router. Thanks in advance.
Isaac

I also have this base station- I found it new in the shrink wrap at the thrift store for $2.
I have a small house, so I don't really need an 'extreme' network.
I have a macPro running 10.6.4.
I also downloaded that app AirPort Admin Utility for Graphite and Snow 4.2.5, and read the accompanying article Mac OS X 10.5: Can't configure a supported Apple Wireless device using AirPort Admin Utility for Graphite and Snow.
I did get info and checked the "open using rosetta" checkbox, only to get the message "You can't use this version of the application AirPort Utility for graphite and snow.app with this version of Mac OS X."
The newer Airport utility cannot see the device, although i can choose it from my airport icon, and join the network.
I am using it to connect right now, in fact. The problem is, I cannot admin the network, rename it, or give it a password, so all my neighbors can use it now also if they wish.

How to setup airport extreme A1034 using snow leopard?

I bought a used Airport Extreme A1034 and, barring that it is not broken, am I able to set it up as wireless base station? I am using snow leopard, I currently use an airport express as a wireless router. I cannot get the airport extreme to appear in my airport utility wirelessly. It will appear in the airport utility if it is connect to my Mac via ethernet, but when I go to save the settings and the device goes to reseet, it just does not come back online. I have done numerous factory default resets. Any advice?
