Dual band set up with Airport Extreme "2nd Generation"?

I'm running an Airport Extreme as my Wi-Fi router. When I open Airport Utility it finds the Airport Extreme and calls it "Airport Extreme 802.11n 2nd Generation." I'd like to run this in dual band, since I have some older Airport Expresses that can't go 5Ghz. Is this possible with this unit? I can't find this unit on the Apple site, to get specs. If I can't run it in dual band mode, I end up changing the config every time I want to stream music to my older Airport Expresses. I get much faster Internet performance on my MacBook Pro when the Airport Extreme is set to 5Ghz.
Can someone list out for me the settings that I should use, to at least get the best performance out of this router, and my Airport Expresses. I have the Expresses set to "join a network" so they don't slow things down. Maybe that's not the right settings? My Apple TV, 2 Airport Expresses, iPad, iPhone, MacBook Pro and wife's PC need to share this/these network(s). Any suggestions? Please be specific. Thanks.

This version is not a simultaneous dual band router. You can run a 5 GHz network...or...a 2.4 GHz network, but not both at the same time. A simultaneous dual band version....3rd Generation AirPorts and higher....would allow the wireless router to provide both types of signals at the same time.
I get much faster Internet performance on my MacBook Pro when the Airport Extreme is set to 5Ghz.
That would be expected, since a good 5 GHz wireless connection will run...on average.....at 2-3 times the speed of a 2.4 GHz connection.
I have the Expresses set to "join a network" so they don't slow things down. Maybe that's not the right settings?
If these are older "b/g" versions, that is all that you can do. Newer "n" versions of the Express could be configured to "extend" the network, providing more wireless coverage while running at higher "n" speeds.

You already know that 5 GHz provides the 'best" performance for your Mac, but if you have older AirPort Express devices, they cannot connect at 5 GHz. Neither can an iPhone or iPod, and probably the PC as well.
So, the best compromise on your current Extreme would be to use the default settings for 2.4 GHz, which would provide an 802.11 "b", "g" and "n" wireless signal....compatible with all of your devices. You may already be doing this.
If you decide to purchase a newer version of the AirPort Extreme, then you will have the benefit of being able to run both 5 GHz and 2.4 GHz networks simultaneously....so everything will connect to the respective 'best" signal.
Then the current AirPort Exteme that you have now could be reconfigured to "extend" the network if you need more wireless coverage in another area. But...another compromise coming.....it can only "extend" one band...either 2.4 GH or 5 GHz, but not both.
Unfortunately, you would need another simultaneous dual band AirPort to be able to "extend" both bands.

Will my airport extreme 2nd generation work with docsis 3.0 cable modems?

Will my airport extreme 2nd Gen work with docsis 3.0 cable modems?

RRoger, everything is working fine.
So, what is the actual problem here? You are now wondering if the Vonage can handle the speed from the modem? Is that the "problem" after all this discussion?
now I am wondering if my current setup will allow me to get docsis 3.0 speeds.
What speed is your Internet provider delivering to you?
The AirPort Express uses 100 Mbps Ethernet ports, so it will handle up to 100 Mbps. We have already told you that.
Vonage likely does the same. The answer is almost certainly "yes" .......both the Vonage and AirPort will handle the speed from the modem.
If you want to double check this, please provide the model number of the Vonage, and we will try to look up the specifications for the device. If you have documentation there with specifications for the Vonage device, check to see if the Ethernet ports are listed as 10/100. This is standard with almost all devices, with some of them handling even higher speeds 10/100/1000.
Chances are, your network will handle a lot more speed than your service provider is supplying to you. So, the "choke" point on your network may very well be your service provider and modem......not the Vonage and AirPort.

Extend 5 GHZ network with airport extreme 5th generation

I'm having issues extending a 5 ghz network with an airport extreme 5th generation. Here is what I have -
1 brand new airport extreme (2013) in the basement connected to the cable modem. It nearly doubled the speed I was getting over the 5th gen.
I moved the 5th generation airport extreme up to the office on the first floor. Due to the construction of the house and a mess that previous owners made with the wiring, it's cheaper for me to have multiple devices extend the network to various parts of the house than it is to tear open the walls and try to fix the coax issue. I have a 4th gen and a 2nd gen, as well as a few airport express models. So, the 4th gen extends the 5 ghz network without a problem. I use the 2nd gen to provide 802.11g (2.4 ghz) to some older devices that can't handle 802.11n. Both work fine. When I moved the 5th gen upstairs to extend the 5ghz network in the office it won't do it.
I did a factory reset on it, Set it up with a new device name, and set it to extend the 2.4 ghz network, and it works without a problem. If I change it to extend the 5 ghz network, it restarts and then flashes amber. The airport utility can no longer see it and I have to do a factory rest in order to get it working again. I downgraded the firmware, but that made no difference.
Any idea why the 4th gen works for this, but the 5th gen fails ?

At times, a Hard Reset will not completely clear all of the old settings when you reset the device, and as a result, you do not start from a true factory default.
If you have not already done so, try a Factory Default Reset this way.....
Power off the AirPort Extreme
Wait a few minutes
Hold in the reset button first, and keep holding it for 9-10 seconds while you simultaneously plug the power back into the AirPort Extreme
Release the reset button after the hold period, and allow a full minute for the AirPort to restart
Not sure what else to suggest, other than taking the device to an Apple Store.....if you have one near you....to let them take a look.

Windows 7 conflict with airport express 2nd generation

My airport express (2nd generation) is losing it's wifi connection with my router after being connected for an hour or so. It was worse (happened faster) until I made some setting changes. Here is the current config and purpose of what I am trying to accomplish...
Goal - Connect my son's new gamer computer that is running windows 7 professional to the internet
Config -
1. Airport is set up to connect to an existing wireless network that uses WPA/WPA2 Personal security
2. Ethernet cord is plugged into the ethernet slot in the back of the airport and runs to the ethernet slot on the computer.
Once the connection is lost, all you have to do is unplug and re plug in the airport and the light goes green and all is good for a little bit.
Yes, I have unplugged, disconnected and reconnected the router, too after making changes.
Any help would be greatly appreciated.

Airport Extreme 2nd generation on a roaming network: is it capable of doing this?

I am having difficulty setting up a roaming network using a 2nd generation Airport Extreme and Airport Express. Airport Utility doesn't "see" the Airport Express when it is connected to the Airport Extreme via CAT 5 cable. Apple support document for setting up a roaming network references applicability to Airport Extreme 3rd generation. Is a 2nd generation unit not capable of doing this?

What I would like for it to do are the following:
- host h.264 videos that can be viewed either on the web or downloaded
Yes.
- host all types of files that can be embedded or downloaded, such as .PPT, .doc, .PDF, etc.
Yes.
- host .flv files that can be embedded on various pages
Haven't tried hosting flash video. Apple tends to host H.264 streams.
- setup to push images to Macs across our organization
Yes.
Does any of this seem unreasonable?
No.
Can it do all of this simultaneously?
The web serving capabilities of an Xserve box are typically limited by sufficient storage and network bandwidth. The box itself is fast. Some folks look to use content providers for higher-volume requirements; this for loads larger than your network bandwidth and your available Xserve servers.

Unable to connect mac OS 10.4 with airport extreme 4th generation

I am setting up an old PowerBook G4 for my nephew. Running Mac OS 10.4.11. I am unable to get the PowerBook G4 to speak to my Airport Extreme 4th generation. Is this an incompatibility issue that cannot be fixed?

I guess it's time to go down to Starbucks and buy an overprised Latte
If the coffee place is running an "open" network that does not use wireless security, the G4 should connnect.
If the coffee place uses WEP 40 or WEP 128 encryption, then the G4 will likely connect as well.
My guess at this point would be that the AirPort Extreme is using WPA2 Security and the G4 operating system...or the wireless card in the G4.....will not support this level of security.
So, although the G4 might be able to handle OS X 10.5.7 or higher, the wireless card may still limit what you can do.
Things might be a whole lot easier....and a lot less expensive than a new wireless card.....if you try a USB wireless adapter on the G4.....assuming that the G4 supports a USB connnection.

Will I be able to extend a dual band network from a Time Capsule 2nd generation with the new Airport Express on both bands?

My Time Capsule 2nd generation is the main accesspoint in my house. It resides on the second floor in our living room. On the first floor in our kitchen I have an fairly new Airport Express that extends my network on the 5 GHz band and allows me to stream music via Airplay. I had to choose 5 GHz since the 2,4 GHz band is interfered when using the microwave oven. However, we have a rather old house with loads of metal in the concrete walls and therefore the 2,4 GHz signal from the second floor proivded by the Time Capsule is hardly available on the first floor. Since all our iDevices (iPhones and iPods) operate at the 2,4 GHz band we sometimes don't have a proper wi-fi connection. I had tried before with another (older) Airport Express that only operated at the 2,4 Ghz band, but I could get a proper connection between the Time Capsule and the Airport Express. Therefore I think it would be the best solution if the new Airport Express would provide both bands simultaneously.
If I replace my existing Airport Express with the new one, will I be able to extend my network on both bands?

It sounds like you may have configured your Time Capsule to use a separate name for the 5 GHz network and then setup the Express to extend that specific band.
In order to extend both bands, the Time Capsule setup will need to be changed so that both bands are using the same name. In other words, you would uncheck the option for the 5 Ghz name.
Then, setup the new Express to extend the Time Capsule network.
This is the only way that they Express can extend both bands. It cannot extend both bands if you have assigned a separate name to the 5 GHz network since you will be forced to choose either the 5 GHz band or the 2.4 GHz band for the Express to extend.
How the microwave oven will affect this is not known. This will one of those things that you have to try in your home to know if it will work well, so it might be a good idea to understand the store's return policy before you buy....in case things do not work out as hoped.

Extending a simultaneous dual-band network using an Airport Extreme

I have a new Time Capsule that can operate in simultaneous dual-band mode. I have a single SSID for both the 2.4 GHz and 5 GHz networks, and all of my devices correctly connect using the appropriate frequency.
I also have an older square Airport Extreme that's dual-band capable (but not simultaneous dual-band). I have this Airport Extreme set up to extend the network from the Time Capsule, but it's extending the 5 GHz network rather than the 2.4 GHz network. I'd rather have it extend the 2.4 GHz network because our iPhones move around the house much more often than our other wireless clients.
I know that I could go back to having different SSIDs for the 2.4 GHz and 5 GHz networks, and then telling the Airport Extreme explicitly to extend the 2.4 GHz network, but I'm really enjoying having a single SSID that any device can use to connect to my network.
Thanks,
Scott Gardner

Thanks for the replies. Right now, there's about 30 feet, two interior plaster/lathe walls and a closet between the Time Capsule and the Airport Extreme. The area of the house where I'm trying to improve the 2.4 GHz reception (an attached studio) is only about another 18 feet, one interior wall and one exterior wall further past the Airport Extreme's current location. I can't put the Airport Extreme any further from the Time Capsule because the 18 feet between its current location and the attached studio is an open area.
If there are no hidden settings that I'm missing, I guess I'll just break the network back into two discrete SSIDs and explicitly tell the Airport Extreme to extend the 2.4 GHz network.
Thanks again,
Scott Gardner

Also, check the App Store for apps from your printer manufacturer.
Apps such as Printopia and others are highly recommended and allow printing to a variety of devices, but I have not tried it.

How can I strenghten a weak Airport Extreme (2nd Generation) signal?

I have been having a weak WiFi signal in my Airport Extreme. Even when I am in a room that is less than 30 ft away.
Here are the details:
AirPort Extreme 802.11n (2nd generation)
     Version: 7.6.1
     Wireless Mode: Participate in a WDS network
     Wireless Security: WPA/WPA2 Personal
     Channel: 6
     Connect Using: Ethernet
My Airport Extreme is on the second floor of the house and is connected to a D-Link DIR 825 router that is on the first floor.
Sometimes when I am on the second floor, I get a better signal from the D-Link router than from the Airpot Extreme.
How can I strenghten the signal?
Thanks in advance

The 4th Generation version was introduced in October 2009.

AirPort Extreme 2nd Generation

Hello, i want to ask, can i connect HDD to this device, to use it for time machine, or LAN Hard drive and to download information directly to it?

The 2nd Generation AirPort Extreme does not support Time Machine backups to a drive connected to the USB port on the device. That being said, there are always some users who will claim that they have been able to make it work.
As far as connecting a hard drive to the LAN port on the AirPort Extreme and using that for Time Machine backups, you would have to check with the drive manufacturer to verify if that might work.
The 2nd Generation AirPort Extreme will support up to a 4 TB USB drive. I do not know if there is a limitation on the Ethernet ports.

Iphone 4 won't connect with airport extreme 5th generation

Just bought a brand new AP extreme, and the computer links up fine, but iphones repeatedly time out.
Any ideas?
Running Lion, and iOS 5
Thanks in advance.

Ditto here too. I was helping a friend update her AP Extreme today. Reset the modem. Reset the AP Extreme. iMac links wirelessly with the AP Extreme and gets to the Internet - no problem. However, not one iPhone in the house (3 of them - one iPhone 4 and two iPhone 3s) will access the interest with the AP Extreme.
Each of the 3 iPhones recognized the AP Extreme and one of them (a 3 without updated software on it) will actually show that there is a connection to the AP Extreme. Two of the iPhones (4 and 3 (both of which have latest updates) work perfectly everywhere else we've been (FL, NC, Germany) in the last few weeks. They also work perfectly on the two AP Extremes in our house.
I've read a bunch of support and this seems to be a recurring problem for which there does not appear to be a good solution. Is there anything more current in guidance that might help????
Thanks also in advance.

What model and firmware is the 2TB TC?
What firmware is the AE?
Does the AE get good signal from the TC in its current location?
Signal can only be extended that is received intact.
Is it extending on 5ghz? As I remember it a Gen2 AE is only single band, although you can choose either 2.4ghz or 5ghz.
I am fairly sure you are going to tell me your TC is AC model..
I would do a couple of things..
1. Fix the wireless name, make it short, no spaces and pure alphanumeric.
2. Fix the wireless channel for 2.4ghz so it is not going to jump around.
3. Get real results from the AE in its current location for signal strength.. this is really only possible on v5 utility. And that is a double pain with Mavericks because you cannot use it.
Apple have removed all the useful diagnostics from the airport utility. There is next to nothing left. So you need to use the computer and its diagnostics to find signal levels in the location.

How can I set up an Airport Extreme as a router, in conjunction with my AT&T modem/router?

I am trying to set up an Airport Extreme as my router, and I am currently using an AT&T modem/router combo. I am wondering what would be the easiest way to do this. Any help would be appreciated. Thanks!

Connect an Ethernet cable from one of the LAN <-> ports on the ATT modem/router to the WAN "O" port on the AirPort Extreme. This cable must remain in place permanently.
Open Macintosh HD > Applications > Utilities > AirPort Utility on your Mac
Click on Other WiFi Devices
Click on AirPort Extreme xxxxx
The utility will take a moment to analyze the connection, then a screen similar to this will appear with your AirPort Extreme instead of an AirPort Express
Type in a short simple name that you want to use for the wireless network
Type in a device name for the AirPort Extreme
Enter a password that will be used for both the AirPort Extreme and wireless network
Verify the password
Click Next
The utility will setup everything for you. When the message of Setup Complete appears, click Done and close AirPort Utility.
The AirPort Extreme wireless network is now available.
