Is Airport Express 802.11n compatibile with Airport Extreme 802.11g?

I can't get my new AExpress 802.11n to coexist with two other 802.11g AExpress and a AExtreme 802.11g. I have tried every type of reset and upgraded all soft/firmware but I can't see all three!
Do I have to ditch my older model Express (g) and Extreme (g) or try and get a second user old model Express (g)?
has anyone got a mix of old and new Express to co-exist?

good response. What to try? I'll admit it is a pain but this would be the basics:
1) reset it as many times as necessary to get it to be recognized
2) reset it with the power unplugged also
3) always use the airport icon found at the top of the desktop file menu(this is the key to find it there first
4) use the preferred pane found in the network pane within system preferences, delete networks that are odd or old and if you can get that express showing there you are almost home. Use the above three to do it also
This is why I got off those routers and now use two TC or two Extreme N or a combination of each. Ethernet as much as possible. Good luck
also
5) use ethernet to configure it then remove it, but once you set its wireless setting make sure you see it in the airport icon.

  • Airport Express 802.11n joining existing Aiport Extreme 802.11g network

    We added an Airport Express to support Airtunes on a stereo system to an existing Airport Extreme 802.11g network. The original Extreme had an antenna to extend its range as well. The problem we are having is that the connection from an iMac keeps going up and down. Is there an issue using WDS between Airport units that are of different speeds? Any thoughts on why this might be doing this and how we can get it to operate stably again as it was with just the old Airport Extreme.

    I am concerned with the speed being reduced by half per node. Do you mean if I had three access points in a WDS network the speed would be half or does it reduce to one third?
    Also, I want to point out in the latest manual, WDS does support 802.11n and mixed, including wide channel, which may over come being halfed but not further reductions.

    Setting Up a Wireless Distribution System (WDS)
    When you connect devices wirelessly in a WDS, you set up each device as
    either a main, a remote, or a relay device.
    You can connect AirPort Extreme 802.11n Base Stations or Time Capsules and use the
    5 GHz frequency band in the network. Only client computers that have 802.11n wireless
    cards installed can join the network. If you want client computers using 802.11b or
    802.11g wireless cards to join the network, set up the network using the 2.4 GHz
    frequency band, or add 802.11g AirPort Extreme or AirPort Express to the network. See
    “Choosing the Radio Mode” on page 21 for information about setting the frequency
    band of the network. You can also set up a dual-band network that utilizes both the
    2.4 GHz and 5 GHz frequency bands, so client computers using 802.11n wireless cards
    can join the 5 GHz segment of the network, and computers using 802.11b or 802.11g
    wireless cards can join the 2.4 GHz segment. See “Setting up a Dual-Band (2.4 GHz and
    5 GHz) Network” on page 48.

  • Using Non-Apple 802.11N Adapters with Airport Extreme

    I have an Airport Extreme Base Station but both N enabled and G enabled Macs in the house. I'd really like to set up the network as an N network. And since I can upgrade the Airport Cards in the older Macs, can I use 3rd Party 802.11N adapters (USB 2.0 for example) to get the older Macs onto the N network? Otherwise, it seems to defeat the purpose of having the 802.11N enabled Airport Extrement and iMacs.
    I see that Netgear and Edimax have such adapters, but neither lists Mac OSX as a supported OS.
    Thank you.

    Thank you for your comment. But unfortunately, I still need to run my non-N machines. So I think my choices are:
    1. Try somehow to replace the older Airport Cards in those machines with N-Cards which seem like a pain
    2. Have 2 networks, one N and one non-N
    3. Try some of these 3rd Party USB or PC Card Slot N-Adapters
    Seems like 3. is the least painful option?
    Any advice on whether I can use 3rd Party N-Adapter would be very appreciated! Thanks again!

  • How to extend range of my wireless network with an Airport Express connected by ethernet with Airport Utility 6.0

    Hi everyone,
    I have AirPort Express 802.11n (1st Gen) firmware 7.6.1, that is connected to my main wifi base station (a TimeCapsule) by ethernet. I would like to extend the range of the Wifi Network but am not clear on how to do so using the new interface of Airport Utlity 6.0.
    Does anyone have any tips on how to do this?
    BR
    AK

    Hi Everyone!
    Many thanks for the tips. I have downloaded 5.6 and have set my Airport Express in the "Extend a wireless network" mode. I was still having a few problems with the quality of the wifi connection in different parts of my apartment (by no means a very large one, but walls seem to be made of extra dense concrete here in Singapore) and went out and bought a few powerline adapters by TP Link (http://www.tp-link.sg/products/details/?categoryid=1862&model=TL-PA211#spec).
    If you don't mind a slightly long post, I would be very grateful for any tips:
    My setup is now as follows:
    Main room
    Time Capsule - connected to a Cisco DPC3925 Modem (http://www.cisco.com/web/consumer/support/modem_DPC3925.html) both connected to a TP Link adapter 1.
    iMac - connected via Ethernet to TP Link adapter 2 and wifi enabled
    Airport Express 1 - connected by Ethernet to TimeCapsule (and thus TP Link adapter 1) used to stream audio to a stereo that doesn't have an optical cable input. Since it is an Ethernet connection, I have wifi turned off.
    Apple TV 1 - connected by Ethernet to TimeCapsule (and thus TP Link adapter 1)
    Bedroom A
    Airport Express 2 - connected via ethernet to TP Link adapter 3
    Bedroom B -
    Apple TV 2 - connected by Ethernet to a TP Link adapter 4
    After following the tips on setting up the extended wifi network, I find that when I use a wireless client (e.g. iPad, Macbook air, etc) in either Bedroom B or Bedroom C (both don't have wifi in the room) the connection is very poor. Even more odd is that the connection in Bedroom A, one that does have Airport Express 2. To be clear when I mean very poor, I mean Skype/facetime skips frames and freezes... this doesn't happen when I am in the main living area.
    I would be very grateful for tips on how to set up the most robust network given the configuration above. Specifically, I am wondering about:
    When I select Extend a wireless network option on Airport Utility 5.6 the summary page states that it is connecting using "Wireless Network" vs what I would expect it to say "Ethernet connection".
    Is there any advice on whether to enable 5Ghz network and if so, should I try to use that for the various wifi clients?
    Does anyone know if I can somehow use Apple products to extend the reach of the Cisco DPC3925? Frustratingly the signal is quite strong (compared to Apple routers), but I cannot properly stream audio/video if that wifi network is used (as my iMac that hosts the content is on the Apple one... and I'd have to walk over to switch it to the Cisco one).
    Any other tips would be much appreciated!
    Cheers!

  • AE 802.11n working with earlier AE 802.11b

    I am running my imac and non-mac laptops through the 802.11b and have purchased the 802.11n. Is it possible to hookup the 802.11n in another room (2nd floor) and pickup a signal or is it better to use the 802.11n as the main AE and hookup the 802.11b as a secondary...

    NU-Mac boy, Welcome to the discussion area!
    The 802.11b base station is not an AirPort Extreme base station (AEBS). The 802.11b base stations were the graphite AirPort base station (ABS) and dual-Ethernet (aka 'snow') ABS.
    Neither of the 802.11b ABSs will wirelessly extend an AirPort Extreme base station (AEBS).

  • WDS networking issue - Airport Extreme (802.11n) and remote Airport Express

    *Background Info:*
    Airport Extreme 802.11n (Fast Ethernet)
    Version: 7.2.1
    Wireless Mode: Participate in a WDS network (set as main)
    Network Name: @Home
    Wireless Security: WPA/WPA2 Personal
    Channel: 1
    Airport Express
    Version: 6.3
    Wireless Mode: Participate in a WDS network (set as remote)
    Network Name: @Home
    Wireless Security: WPA/WPA2 Personal
    Channel: 1
    Radio Mode: 802.11b/g compatible
    Connect Using: AirPort (WDS)
    Connection Sharing: Off (Bridge Mode)
    Issue
    Please help as I'm having issues with my WDS network. I've setup using both the wizard and manual and also hard reset on both units to setup again but cannot get them both to communicate to one another. Both units are showing green LED under their configuration. For my last attempt, I've tried adding the Airport ID (MAC) of the Airport Express to the Access Control and also DHCP Reservations on the Airport Extreme but still no luck.
    The Airport Express (setup as remote) does not even show up in the Airport Extreme's Summary as Wireless Clients. In the WDS tab, the Airport Extreme is set up as WDS main, Allow wireless clients box checked and WDS Remotes has the Airport Express' AirPort ID in the list. On the Airport Express, WDS is set up as remote, with Allow wireless client box checked and the Airport ID of the Airport Express in the WDS Main.
    I can connect clients to both units. Both units are configured using the same Network Name and have the same WPA/WPA2 security key. The Airport Extreme (main) however is connected to my broadband so any devices or clients connected to it are able to get outside. Connected devices or clients are assigned IP address via DHCP with IP 10.0.x.x. If wifi devices or clients connect to the Airport Express (remote) they are assigned a completely different IP addresses 169.254.x.x, they are not able to browse the internet or talk to other clients connected on the 10.0.1.x network. The Internet Connection configuration on the Airport Express (remote) is Connect Using Airport (WDS) and Using DHCP. I've even tried manually and entered the IP address 10.0.1.199 that I had assigned to the Airport Express from the Airport Extreme and Router Address as IP of Airport Extreme (10.0.1.1).
    I think I've tried everything but I'm still having this problem. The remote Airport Express is not extending my existing Airport Extreme network. Any ideas???

    Christopher,
    This may or may not be helpful, or it may be something you've already tried or are aware of so I apologize if that's the case.
    I have been researching ways to set up the Dual Band Network supported by the AEBS and came across your post. I've got an AEBS and (2) AirPort Express set-up currently (AEBS is main and the Express are participating in the WDS as remotes) and I'm trying to configure one of the Express to utilize a 802.11b/g compatible network while the AEBS runs a 5Ghz 802.11n Only network.
    AAR, since the AirPort Express are 2.4Ghz 802.11b/g ONLY (no support for 802.11n), you have to be sure to set-up your AEBS first and select "802.11n (802.11b/g compatible)" in the Radio Mode drop-down on the AEBS before you attempt to connect an AirPort Express. The AEBS should be set-up as your "WDS main" and the Express should be set-up as a "WDS remote" for the network you established when you set-up the AEBS.
    Bottom line here is the Express won't be seen by the AEBS unless the AEBS is 'looking' in the 802.11b/g 2.4Ghz frequency.
    Hope this was helpful.

  • HP laserjet P2035 on airport express not playing nice with Windows

    I recently bought a new HP laserjet P2035 and hooked it up to my network via the usb connector on an airport express 802.11n. The Airport Express extends my network created on an Airport extreme 802.11n dualband.
    I have a MBP 13 and it prints fine. The problem I have is with two PC's. I installed Bonjour on both of them (one on Vista and another one on XP) and they started to print fine. The next day, only my Mac was able to print. Nothing changed whatsoever. Only that I turned off the printer for the night.
    I checked and both Windows machines and the printers appear just like they did the day before.
    Any ideas?

    Anybody?

  • AirPort Express doesn't work with SB5100

    I'm helping a friend set up a new AirPort Express  MC414LL/A Model A1392 (802.11n) with her existing Motorola SB5100 DOCSIS 2.0 cable modem. I was able to setup the AirPort Express from her iPad with a network name and password. Also upgraded the firmware in the AirPort Express. However, the Airport Utility App on my iPad and iPhone connected to the AiPort Express, but showed no connection to the Internet. Furthermore, the PC that had been working fine when connected directly to the SB5100 could not make an Internet connection when connected to the AirPort Express.
    I brought the AirPort Express home and connected it to my Verizon FiOS Actiontec modem and it works fine - my iPhone and iPad connect to it and through it to the Internet.
    I'm wondering if the SB5100 is incompatible with the AirPort Express??

    It should work.
    Power down the modem and leave it powered down for a long time, as much as a half hour or longer is sometimes required. While it is powered down, disconnect its coaxial cable. Literally unscrew it and leave it that way.
    Connect the Express to your modem, leave them connected, and do not disconnect them from one another without powering down the modem again.
    Re-connect everything including power and let the devices complete their startup sequences. This usually takes a moment or two.
    If that does not result in success, "hard reset" the Extreme or Express according to the instructions below and start over from the beginning.
    If you still have trouble, contact AppleCare because you have done everything reasonable to get it to work.
    To "hard reset" an AirPort Base Station: make sure it's powered up, then press and hold its tiny reset button and keep it depressed for five to ten seconds, long enough for its LED to flash amber rapidly. Release the reset button. Then, the LED will glow amber steadily for about a minute. Then, it will flash amber, slowly, about once every second or two, waiting for you to configure it with AirPort Utility.

    I have bought a new airport express and using it with my macbook (iTunes 10.2.2). I have joined an existing wireless network for internet in my home and with that i am trying to play the music via itunes but there is audio dropouts every 60 secs or so. I am using a set of speakers from kenwood connected to the airport express. The operating system on my macbook is mac os X 10.5.8. i am sure it is not a problem of streaming music online because i have even tried playing music which are stored in my macbook.
    Is there any problem with the setting in itunes or quicktime ? Kindly reply...... I am waiting for your valuable suggestion.
    Thank you a lot in advance.

    I am shocked to have found this same AX audio dropout problem starting TODAY, every few seconds the audio just drops for a couple seconds and then resumes:  Latest software versions of everything.  No iPad, iPhone or Touch.  Internet hardwired to D-Link DES1105 (1000baseT Switch) hardwired to new 80211N AX, AX optical to stereo, AX Wi-Fi internet to basic 1st-gen MacBook operating at 80211G, and an older 'G' AX extender at the far end of the house, away from all this.  The MacBook streaming iTunes is usually 12 feet from AX.  I've used this setup for years of trouble-free AirTunes / Airplay until today.  Today I also found 2 very reliable fixes and 1 way to force a dropout, but first, I read some posts and tried ALL following settings one-at-a-time and restored them ALL because NONE of them helped:  Turned off IPV6.  Streamed to multiple speakers 'Computer' and 'AX' (restored to just AX).  Turned off 'Ask to Join new (WiFi) Networks'.  Turned off Bluetooth (can't live without Magic Trackpad, so glad that wasn't it).  Here's my discoveries:  Lo and behold, each time I click the Airport icon in the Menu (you know it shows you've got 4 bars from AX) when the status switches to 'Looking for Networks' for a second it CAUSES the AX audio to drop out for a couple seconds (it never did that before today.)  iTunes still playing, streaming, AX laser still lit, but the 'PCM' light on stereo and the sound GOES OUT EVERY time I click the Airport icon in the menubar, just like the regular, annoying dropouts.  So, to reduce traffic I quit Safari (3 tabs, no streaming, just Gmail, Google, and Netflix browsing).  Lo and behold, the dropouts stopped altogether.  No other Web apps going (not iTunes Store, Genius, Ping, nothing), so I launched Chrome to the same 3 tabs and the dropouts HAVE NOT RETURNED.  That's right, not only did simply QUITTING SAFARI cure it, and Chrome doesn't contribute to it, but I can demonstrate it just by forcing my Airport to re-scan.  Works for me, written using Chrome.  The other reliable fix is to hardwire MacBook to the Switch.  This is obviously not ideal, but Airplay audio doesn't drop out over Ethernet.  Also, in all my tests, it made no difference whether iTunes did the streaming, or Airfoil did.

  • "Airport Express" is not compatible with this version of itunes

    Hello- My itunes reports that my airport express is not compatible with this version of itunes.  My ipod and iphone no longer sync with the device either.  Any suggestions?  Thanks!

  • Hi, The Airport Express does not work with iOS 7.0.4, I appreciate your help to resolve this event. Thank you,

    Hi, The Airport Express does not work with iOS 7.0.4, I appreciate your help to resolve this event. Thank you,

    Please locate the model number of the AirPort Express and post back that information.
    The model number is located on the side of the AirPort Express. It begins with an "A" followed by four numbers.
    We are not sure what you mean by "does not work".  Does this mean that the AirPort Express worked at one time and has just recently stopped working?
    Have you installed a newer operating system on your iOS device recently?
    Or, is this a new AirPort Express that you are trying to configure for the first time?
    If yes, what service will the AirPort Express perform on your network?
    Please remember that we cannot see your network, so we only know as much about your problem as you can tell us.

  • PROBLEM: Trying 2 add an AIRPORT EXPRESS to an already existing AIRPORT EXTREME network

    I'm trying 2 add an AIRPORT EXPRESS to an already existing AIRPORT EXTREME network in my home.
    I see the EXPRESS in ARPT UTILITY but when I click on "CONTINUE" or "MANUAL", the only option I'm given is to SWITCH networks, which I do not want to do.
    I am using a MACBOOK PRO (MAC OS X 10.6.8)
    Can someone offer me help with this?
    Thanks!

    Hi, I have a similiar setup.  When you click onto the express, and it asks you to switch networks, it's not actually asking you to "change" networks.  It's just actually switching to the xpress.  When the xpress comes up, you'll input the name of your existing network, which you set up and named for the extreme.  You'll have to change the extreme to "participate in a network", which is what you'll also do for the xpress.  In the extreme under the WDS tab, you'll input the wds mode as "wds main".  And then put a check mark in the "allow wireless clients".  Where it says wds remotes, you'll input the the airport id's for the xpress's.  In each of the xpress's, you'll set up as participating in a wds network.  In the xpress's, under the wds tab, you'll set the wds mode to remote, and check
    mark in the allow wireless clients.  You'll have to input the airport id of the extreme in the wds main block.  Under the internet icon on top, in internet conect tab for connect using: airport (wds), connect sharing: off (bridge mode).
    Remember to insure that the express's show the same channel as the extreme, if you're using 802.11n (80211b/g compatible).  Of course the security that you decide to use should also be the same.

  • Is there a way to turn the wireless capabilities off on an AirPort Express?  I have an AirPort Extreme as my main router and use the express to just extend it. I only really want to you use the express for hard ethernet connections

    Is there a way to turn the wireless capabilities off on an AirPort Express?  I have an AirPort Extreme as my main router and use the express to just extend it. I only really want to you use the express for hard ethernet connections. For whatever reason when I have my express extend my wifi at home the download speed from just the express is absolutely terrible, drops to about 1.5 mb compared to when it's on the extremes part of the network the speed goes up to 50-75mb. These terrible download speed really only affects the iPhones as my MacBook Pro usually gets the good speed no matter where it is. I don't believe there is anything wrong with my phone because if I am in the part of the house that uses just the extreme the download speeds on the iphone goes up to 50-75mb. As a note I have an AirPort Extreme on the top floor of my house (second floor) that's where my modem is located. On the first floor that's where one airport express is located. I also have another airport express in the basement that is accessed by my landlord. Any thoughts on how to fix this would be helpful.

    It appears that your networking goals with the AirPort Express is to use it as a wireless Ethernet bridge instead of using it to extend the wireless range of your AirPort Extreme. The latter requires that the Express Wi-Fi radios be enabled.
    If you intended to use the Express as a wireless bridge, you just need to reconfigure it to "Join a wireless" network instead of "Extend a wireless network."
    For whatever reason when I have my express extend my wifi at home the download speed from just the express is absolutely terrible, drops to about 1.5 mb compared to when it's on the extremes part of the network the speed goes up to 50-75mb.
    In an extended network, the placement of the extending base station is critical as it can only extend the wireless network at the bandwidth at which it receives it.
    Please check out the following AirPort User Tip for details on optimal base station placement.
