What does my airport express do

what exactly does my airport express do?

An AirPort Express can create a wireless network, extend an existing network bridge an existing router...what do you want it to do is the real question?

Does The Airport Express Work with Any Router?

Hi Forum,
i have an old Linksys router G Wifi speeds, does the Airport Express work with this?

The AirPort Express or other Apple routers will not wirelessly extend the signal from your Linksys router, if that is what you are asking here.
If yes, use another Linksys product to insure compatibility between devices.

Why does my Airport Express say "self assigned IP address"? No IP address for the ethernet, and it is not connecting to my cable router any longer...

Some cable providers.....like mine, a well known company......seem to take anywhere from a few moments to sometimes up to 30 minutes to allow their equipment back at the cable company to fully reset and issue a new fresh connection.
So, it would not hurt to leave things powered down for 15-20 minutes or more when you perform the reset that John Galt suggests.

I just purchased Apple TV AND AIRPORT EXPRESS. I am questioning if I need it when I already have a Netgear Powerline AV 200 Adapter Kit XAVB2001. Does the Airport Express do the same thing?

Thank you so much. Any specifics I should know about prior to connecting? The goal is to watch Netflix from my iPad or iPhone 5 on my tv (located in different room from where Comcast internet modem is hard wired to main computer in house). Movies would depend on wireless transmission to a smart tv not connected to modem.

How much electricity does an Airport Express use (approximately)?

How much electricity does an Airport Express 802.11n use (approximately)?
Is turning it off at night to save money a good idea or a bad idea?

That's exactly the data I needed to know. Thank you very much!
I was concerned because the Express is always quite warm, which sometimes can mean big energy bills.......

I've just measured it using a digital wattmeter, and it draws 4 watts when idle. This means about 3 kWh/month, or 0.60 €/month (at my current 0.20 € / kWh), so it is not the culprit of my huge energy bill...
Surely it is not worth the hassle of unplugging it everyday, with the accelerated ageing it causes to the device.

Does my Airport Express need to be hardwired to my modem?

My Imac and modem are in my basement. I have an airport express in my garage so i can play music through Airplay. Does the airport express need to be connected to my modem with an ethernet cable, or can it just connect to my wifi network to enable Airplay?

See this article, AirPort Utility 6.x: Set up a bridge or AirPort Express: How to join an existing Wi-Fi network in client mode , about configuring the AEX. Be sure to have your Airport enabled on the computer.
I'm not sure how easy this will be when using a non-Apple router.

Does the airport express need to be on the same floor as the apple tv for best streaming?

Yes. Distance can increase interference causing delays in streaming.

Why does my airport express keep cutting out?

Why does my airport express keep cutting out?

I have a 1st gen Airport Express and use it to stream music from my PC, iPhone 4, iPad and iPod Touch. My Airport Express is connected to a Teac UD-H01 DAC via an optical cable which is connected to an amp and speakers. I had no problems at all with this set up until I upgraded the Airport Express firmware to 7.6.3. The sound then started to drop out frequently. To cut a long story short after various testing, the problem had to be the Airport Express. I called Apple support but they were not much help and couldn't fix the problem and said they would speak to engineering and phone back. While I was waiting I decided to have another go to find the problem and opened the airport utility and saw that there was an option to downgrade the firmware. At this point I realised that the problems started about the same time that I upgraded the firmware to 7.6.3 but didn't think at the time that Apple would release a firmware that didn't work. Anyway I downgraded to 7.6.1 and hey presto, everything worked again. A couple of days ago I noticed that firmware 7.6.4 was available and thought I'd give it a go, not good - same problem as 7.6.3. I've downgraded to 7.6.1 again and all is well. Hope this helps.

Does the Airport Express support the DHCP BROADCAST flag

In trying to connect a vista laptop to an existing Airport Express Network and the internet, went ot MS Help and found an article saying Vista is set with a 0 (Zero) in the Registry (whatever that is).The comment is -
A value of 0 disables this registry entry. You can use this registry entry to prevent Windows Vista from using the DHCP BROADCAST flag. After you set this registry entry, Windows Vista never uses the DHCP BROADCAST flag.
Can someone who doesnt type in UNIX or DOS tell me what might work and if this even applies. I am not inclined to do the following -
Click Start, type regedit in the Start Search box, and then click regedit in the Programs list.
If you are prompted for an administrator password or for confirmation, type the password or provide confirmation.
Locate and then click the following registry subkey:
HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\Tcpip\Parameters\Interfaces \{GUID}
In this registry path, click the (GUID) subkey that corresponds to the network adapter that is connected to the network.
On the Edit menu, point to New, and then click DWORD (32-bit) Value.
In the New Value #1 box, type DhcpConnEnableBcastFlagToggle, and then press ENTER.
Right-click DhcpConnEnableBcastFlagToggle, and then click Modify.
In the Value data box, type 1, and then click OK.
Close Registry Editor.
Hard wired to the Cable Modem the computer can connect to the internet without any of this. What in the Airport Express could be blocking this computer?

Sorry, none of the Apple products support this.

Does the Airport express work with apple TV?

does the airport express base station work with apple tv and connected devices, like the same way it would over a wi-fi router?

Yes. The AirPort Express Base Station (AX) is a Wi-Fi router and supports the Apple TV for connectivity.

Does 2012 airport express support MIMO?

Does 2012 airport express support MIMO? if not, will it slow the internat speed with ipad air?

Welcome,
Probably not, but Apple have stated recently that MIMO is build in to the new WiFi kit, see:
http://www.pcmag.com/article2/0,2817,2426153,00.asp
You may need to upgrade to a new Airport.

Shawn

Does the Airport express base station connect to any modem?

ive got the apple tv in the lounge room where there is poor wi-fi reception and am wondering wether i should get the airport express or get a new modem. what can the airport express do that the extreme cant, and can the express connect to any modem? I have a NETGEAR modem.

By modem, do you mean just a dumb modem or modem router?
If you mean the modem, yes.
If you mean a modem router, yes, but only as an access point, not as a router (unless the Netgear supports modem mode).

What exactly is Airport Express and AirTunes?

Sounds like a system to send music wirelessly to any HiFi... Is that right and how does it work/what do I need? Would an audiophile be satisfied with the quality of sound? i.e. is this something that would be out of place on a high end audio system or more suited to the more usual integrated stereo systems?.
I am using an Apple TV as a music source and just wondering whether the Airport is a possible alternative.
Does the airport also transmit video?
Thanks!

Sounds like a system to send music wirelessly to any HiFi... Is that right and how does it work/what do I need?
The AirPort Express Base Station (AX) is a combination NAT router, wireless access point, print server, and a target device to receive AirTunes audio streams.
AirTunes uses the Remote Audio Access Protocol (RAOP) to stream music to the AX. RAOP is based on the Real Time Streaming Protocol (RTSP) but with an extra challenge-response based authentication step.
For audio playback, you would need the following as a minimum:
o An iTunes host with with either wired Ethernet or wirelessly capability.
o Powered-speakers or an audio receiver with either analog RCA or digital/optical inputs.
o Either a 3.5 mm minijack-to-dual RCA or a 3.5 mm TOSLINK cable.
Would an audiophile be satisfied with the quality of sound? i.e. is this something that would be out of place on a high end audio system or more suited to the more usual integrated stereo systems?
For the AX, the audio is handled by a Texas Instruments PCM2705 digital-to-analog converter which it outputs on a 3.5mm stereo minijack. However, the innermost end of the 3.5mm jack is an optical S/PDIF transmitter.
The AX works only with iTunes v4.6+ and is limited to music files that iTunes can read; ie, 16-bit data only. (An exception is you can use a third-party product like Rogue Amoeba's AirFoil to stream other non-iTunes sources.) These data, though, can be in any file format that iTunes recognizes, from lossy MP3s at the low-quality end of the spectrum to Apple Lossless and lossless AIF or WAV files at the high end. It is also important to note that the AX functions only at a 44.1kHz sample rate. When you play 32kHz or 48kHz data, iTunes sample-rate-converts the data in real time before sending it to the AX.
iTunes uses a QuickTime CODEC to convert audio files to Apple Lossless, and then, uses AirTunes to send them to the AX. In turn, the AX uses built-in software that converts the Apple Lossless to an Encoded Digital Audio format. From there, digital audio is sent to a optical transceiver to convert the electrical signal to an optical one before sending it to the innermost part of the audio port. For analog, the AX has a built-in DAC to convert the Encoded Digital Audio to Analog which is sent to the same audio port.
I am using an Apple TV as a music source and just wondering whether the Airport is a possible alternative.
Unlike the Apple TV, the AX has no means of storing audio content. It is only a "relay" between the iTunes host and the sound playback device. Note: With the latest firmware update, the Apple TV can now use AirTunes to stream to an AX.
Does the airport also transmit video?
No. There are no video CODECs built-in the AX.

HT1515 why does my airport express keep going offline?

i use airport for air play but it keeps going into flashing amber light about every week. why?

I found on some non-Apple tech sites some interesting info. One guy was having the same exact issues and wrote a script to see what was going on between the Airport base station and the Airport Expresses. It appears that the two devices were having security verification issues and that is why the Airport Expresses get getting knocked offline. In other words, when they talk with each other they fail the security verification and the Airport Expresses go haywire.
So the solution is to turn off the security on both the Airport base station and the Airport Expresses through the Airport Utility. Then, on the Airport base station you check the option to create a closed network. In other words, your wi-fi network is now unprotected but it is not broadcasting to anyone that it is there. From then on, you will have to choose "other" on your laptops/iPads/iPhones/etc and type in your wi-fi network's name rather than just choosing your wi-fi network from a list of options.
I did this a few weeks back and I have had zero issues since the very moment I did the above steps. The network is 100% reliable and faster. No more rebooting. Is it a tad bit unprotected? Yes, but no one knows the network is there. If someone is smart enough to be looking for non-broadcasting wi-fi networks and finding yours, then they are sophisticated enough to defeat your normal security protocols anyway. Maybe if Apple ever decides to fix this problem, which appears they might not be interested in doing, then you could go back to normal security protocols. But until then, this works wonderfully. Give it a try and see.

What exactly is AirPort Express

Ok this may sound silly but I've read the apple stores description of AirPort Express and am a bit confused, basically I have a windows desktop at home and also an iBook, my desktop is connected to BTYahoo Broadband via a USB modem my iBook has AirPort built in I believe as it picks up a wireless connection when I'm at work. What I want to know is would an AirPort Express allow me to plug my USB modem into my windows desktop and give me wireless access in my iBook at the same time? Does what I'm asking make sense?

What you are asking does make sense - but things don't work quite as you described.
What you need to do is replace your USB interface DSL modem with a "DSL gateway" that provides the ethernet interface required for connection to an Airport Express.
I suggest you read these discussions:
