Airport Extreme Base Station (802.11n, dual band) antenna

I'm looking to hook up a directional antenna to 2 AEBS's for a point to point bridge application. So, on opening the device, there are 4 antenna connections-- As I understand it this is to support the MIMO capability, correct?
But is 1 for legacy 802.11g / 2.4GHz support? if so, which 3 should I connect to external antenna? if not, is there an advantage to using all 4?

never mind-- found my answer (here: http://www.smallnetbuilder.com/wireless/wireless-features/30974-more-surprises-f rom-the-new-airport-extreme) if anyone else is interested

    Is a very hot AirPort Extreme Base Station 802.11n normal?
    W.W.

    Warm, yes
    If it's uncomfortable to the touch, no.
    Makes sure the device has plenty of air all around and that it does not have anything on top of it.
    It's still hot, then you should contact Apple for a replacment.

  • AirPort Extreme Base Station (New one) Dual band problem

    Hey, I just got an AirPort Extreme Base Station, simultaneous dual-band today.
    Anyone else having some problems with the 5GHz network? Seems my Transmit rate is very unstable. It changes between 7-54. It's 802.11n (5GHz) profile setting.
    My 2.4GHz is staying at 54 (Since I set it for b/g).
    As well, my MacBook Pro keeps connecting every time i update the airport base station, to the 2.4GHz one.

    Welcome to the discussions, dwig365!
    With a good connection, the Transmit Rate at 5 GHz should be in the 200-270 range. One of the perplexing issues with 5 GHz is that the much higher frequencies used in this band are absorbed by walls, ceilings and any obstructions much more quickly that 2.4 GHz signals. In other words, there is much less "power" with 5 GHz signals.
    I've found that unless I almost have line-of-sight between the router and my laptop a few rooms away, the 2.4 GHz signal is stronger and more stable...hence faster. Taking it another step further, although it is not as "fast" as "n", "g" level signals penetrate and saturate much more effectively. It's a question of trade offs as in return for speed, you must give up penetration power.
    It is not likely that you are encountering interference in the 5 GHz band, but it might help to experiment with some different channel settings. Make sure "use wide channels" is enabled under the options button on the Wireless page in AirPort Utility as well.

  • Printing to Ethernet Printers Using Airport Extreme Base Station 802.11n

    I don't want anything extraordinary. I think what I have to set up is pretty simple.
    I have a PowerMac G5 tower and an Airport Network with an older 802.11g AExBS connected to my cable modem. I just acquired an AExBS 802.11n. While I'm sure that people would tell me to ditch the older one an just use the newer one, that is not today's task.
    All I would like to do is to use the AExBS for my 3 Ethernet printers. The printers are:
    Brother HL-2070N
    Brother MFC-420CN
    HP Color Laserjet CP2025dn
    Each printer is plugged into each of the 3 ethernet ports and not the WAN port. I didn't have any problems using my Netgear WGT624 wireless router, so I don't know why the AExBS is giving me such a headache. Is there something simply I'm missing in the instructions? Can anybody tell me if I'm missing something here?

    Now I have managed to delete all but my directly connected USB printers in the Print & Fax area of my System Preferences. What gives?
    I thought this was going to be straight forward. They don't even address hooking up ethernet printers in the manual. I've looked over the web and see other people having the same problem, but their original setup appears to be different and/or more difficult.

  • Can Airport Extreme Base Station 802.11g Connect To Park's Free WiFi?

    The RV resort where I'm staying has free WiFi for Internet connections. It shows up on my iBook's Airport list of possible networks in the menu bar, along with my own local network which is an older Airport Extreme Base Station (white dome 802.11g) which has my HP printer plugged into it via an ethernet cable.
    However, when I am connected to the park's WiFi via the laptop's Airport network choices, I am NOT connected to my AEBS, and therefore cannot print to the printer wirelesslessly. Is there a way for the AEBS to make the connection to the park's WiFi so I can use both Internet and printer from my iBook G4 without having to switch from one network to use the other?

    Is there a way for the AEBS to make the connection to the park's WiFi so I can use both Internet and printer from my iBook G4 without having to switch from one network to use the other?
    Sorry, but no. You cannot connect your iBook's AirPort to more than one wireless network at a time. Since it will be highly unlikely that you will be able to create a Wireless Distribution System (WDS) between your RV resort's Wi-Fi and the 802.11g AirPort Extreme Base Station (AEBS), you won't be able to extend it to meet your needs.

  • Issue with new Airport Extreme Base Station 802.11ac

    I just purchased an AEBS (new model with 802.11ac).  I'm using it with Comcast internet service using a Motorola Surfboard SB6121.
    I have a very odd and frustrating issue.  The internet simply blips in and out.  I have it set up with WiFi and have connected devices such as my iPhone, iPad, Mac Pro, and a Chromebook to it.  I have the issue on all devices so I know it's not device specific.
    The network itself never goes away.  When I look at the WiFi area on my Mac even when the internet isn't working it shows it's connected to the WiFi network.  Also, when the internet is not working the green light is on and staying lit (not blinking) on the AEBS so it appears the WiFi Network part of it works fine.
    As mentioned it's the internet service itself that blips in and out.  What I mean by this is it may come on for 40 secs, go off for 20 secs, back on again, and off, just like that. I have not timed it and that would be hard but it seems to be very regular, something like 40 on, 20 off, and it may not even vary at all.  It's a very bizarre issue.  I have also direct connected the modem via ethernet to my Mac Pro. I used it for several problems with no problem so I know it's not the modem.
    The only thing I can think of is I received a defective AEBS.  I purchased it through Amazon and I almost contacted them to do a replacement and send this one back.  Yet I'm hoping it's something simple with the settings.  Now I have already done a factory reset of the AEBS and that did not help.  Yet I'm hoping it's simply a setting that I need to modify or wipe out.  Any idea of what's causing this or is it simply a defective base station?
    Thanks for your help.

    There is a bug with the modem where the ethernet is not syncing properly.. The bug is particularly bad with SB6121 and SB6141.. so you got it right.. welcome to the bug farm..
    https://discussions.apple.com/search?q=sb6121
    https://discussions.apple.com/search?q=sb6141
    There is no solution.. a new one could do the same. It is not 100% consistent.. I have recommended people use a small 10/100 switch between the modem and the AEBS.. or use a cross over cable. It works for some but not everyone.
    Some modems seem to work better.. but IMHO it is not your problem it is apple's.. and they are keeping quiet as they do.
    Send the AEBS back either for replacement.. and hope for a better one.. or just get a refund and buy something better.. eg Netgear R7000 or Asus RT-AC68U.

  • Multipmultiple Airport Extreme Base Stations: WDS Or "Extend Wireless Network" To Have Wired -- Wireless Bridge?

    Hello there!
    I've been looking for this info, but have as yet been unable to find it. Here's my scenario:
    I have two Airport Extreme Base Stations (both are dual band) and 3 airport expresses. The main internet connection in my house is in one room, where I have an AEBS as the main wireless router. In another room, I have a bunch of ethernet-only devices. I'd like to use the 2nd AEBS in this room, plug the ethernet devices into it and have the 2nd AEBS act as a wired <--> wireless bridge (connected to the same wireless network as the 1st AEBS). I've attempted this via "extend a wireless network," but the ethernet devices don't get past the AEBS they're plugged into. Should I instead be implementing WDS?
    I mention the airport expresses as I'd like to have airtunes & wireless signal in other areas, but would like to keep the set-up as simple as possible (i.e., not config the AXes for WDS unless it's required).
    Thanks in advance for any help!

    Unlike the 802.11n AirPort Express Base Station (AXn), the 802.11n AirPort Extreme Base Station (AEBSn) cannot be configured as a wireless Ethernet bridge.
    However, there are at least two ways to configure it to provide wired clients access:
    Connect the second AEBSn back to the first by Ethernet; reconfigure the second AEBSn as a bridge and disable its wireless radios, or
    Reconfigure both AEBSns into an extended wireless network. For 802.11n AirPorts, this would be called a dynamic WDS. The AEBSn, connected to the Internet would be the "main" base station and it would only require that you enable the "Allow this network to be extended" option in the AirPort Utility. The extending AEBSn would need to be configured with the option, Wireless Mode = Extend a wireless network, enabled.
    In both configurations, the second AEBSn's Ethernet ports would be enabled for wired clients.

  • Using the WAN port as a "LAN" port on the Airport Extreme Base Station...

    Hi everyone,
    I'm re-building my home wireless network and I'm doing so in preparation for the Slingbox AV I ordered last week. Here's my current setup:
    I have a DSL modem attached to an Airport Express (802.11n) in my office broadcasting my internet signal. I have an Airport Extreme Base Station (802.11g) set up in my living room as a WDS extender. I currently use the base station in my living room to connect the DishNetwork ViP722 DVR to the internet and allow me to set recordings remotely on my iPhone when I'm away from home. I use the LAN port on the base station to do this, and now with the Slingbox on the way (should be here early next week), I'm wondering what I need to do to make an internet connection available for the Slingbox AV.
    My question: Will I be able to simply use the WAN port as a "LAN" port since the Airport Extreme Base Station is being used as a WDS? It'd be awesome if the WAN port would become, essentially, a LAN port since it isn't being used.
    Thanks in advance for your advice and insight!

    I'd be surprised if that worked. The operation of an AirPort base station depends on keeping the WAN port and the LAN port(s) separate, as those normally are on two different networks.
    You might consider buying an Ethernet hub or switch, which would allow your AirPort Extreme's LAN port to be shared. Here's an example of an inexpensive one:

  • Airport Extreme Base station does not 'see' Airport w/Airtunes.  HELP!

    I just purchased and installed an Airport Extreme Base startion (802.11n), and it does not 'see' my Airport Extreme with Airtunes. I have already tried re-setting the Airport + Airtunes to the factory settings, but since I installed the new Base station software, I no longer have the Airport Express Sett up assisstant?!?
    What am I doing wrong?

    Your Mac won't be able to communicate with your Airport Express until you reconfigure your Airport Express to join the wireless network now being created by your new Airport Base Station.
    The "Airport Setup Assistant" has been replaced by the "Airport Utility". You can find that new utility installed in your Mac's Applications->Utilities folder.
    What you should do now:
    1. do an factory default reset of your Airport Express.
    2. plug the Airport Express (temporarily) into power in the same room as your Base Station and your Mac.
    3. on your Mac, run the Airport Utility. It should "see" your Airport Express. Click on the Airport Express icon, click to continue (your Mac will switch wireless networks temporarily), click Continue, and follow the instructions for configuring the Airport Express so that it "joins" the existing wireless network created by your Base Station.

  • I recently purchased the Apple Airport Extreme Base Station so that I can have wireless, my question is: so I need anything else so that my guests can have internet access via my router?

    Hello Anyone and Everyone who can answer my question,
    I would like to be able to offer wireless access to the internet for my guest's who use my apartment above my garage that is about 75 feet away from my house/computer. I have a MacBook Pro and have satellite internet service through an ehternet connection. I recently purchased an Apple Extreme Base Station with simultanious Dual-Band (MC34OLL/A), that is in the process of being shipped as I type, and am wondering if I need anything else to install in the apartment for the wireless to work with the Apple Extreme Base Station? Thank you for any help in this matter.
    Sincerely,
    Lizzy

    In AirPort Utility, enable the guest network by selecting your Extreme, then the Edit button, then the Wireless tab, then check the box for "Enable Guest Network":

  • Cannot access certain web sites through Airport Extreme Base Station

    I use the old (round) Airport Extreme Base Station (AEBS). Approximately three weeks ago I could no longer connect to americanexpress.com or to Godaddy or their mail servers. About a week ago the Godaddy sites started working again, but the American Express sites are still not working.
    My current setup:
    - AEBS connected to Time Warner New York cable modem
    - Three Airport Express units - two connected to speakers, and one set up with WDS to provide Ethernet access to computer (PowerMac G5), which is in a separate room from cable modem
    - I also have an Airport card in my G5 to connect directly to the wireless network (but that doesn't solve any of my problems)
    I have tried resetting all the units, and have also tried running the network with all the Airport Express units turned off, none of which as allowed me to access American Express.
    I have the exact same problems with my work-issued Windows 2000 laptop when logged in to the wireless network.
    When I plug a computer directly in to the cable modem, I have no problem accessing any of the sites, which leads me to believe that the solution somehow lies with the AEBS - I just can't figure out what it is.
    Any help/suggestions are much appreciated.

    If you're having trouble with throughput performance or just connecting to some websites, try changing the MTU value, on your Mac, to 1492. (The default value is 1500.) To do so, you can use a utility, like Cocktail or via OS X's Terminal.
    MTU will vary with connection type. Cable and non-PPPoE, can use up to 1500, whereas PPPoE connections (WinPoet, RASPPPOE, Enternet, etc.) can only use up to 1492. For secure VPN connections (i.e., IPSec) use a MTU value less than 1500.
    The best value for MTU is that value just before the packets get fragmented. To test, use the Ping utility.
    OS X: ping -D -s 1472 www.dslreports.com
    WinXP: ping -f -l 1472 www.dslreports.com
    Reduce 1472 by 10 until you no longer get the “packet needs to be fragmented” error message. Then increase by 1 until you are 1 less from getting the same error message. Add 28 more to this (since your ping packet size, not including IP/ICMP header is 28 bytes). This will be your MaxMTU. (Note: If you can ping thru at 1472, stop, you’re done! Add 28 and your MaxMTU is 1500.)

  • Apple TV vs Apple AirPort Extreme Base Station (Simultaneous Dual-Band)

    I have an original 40 GB TV that connects to my new ( (latest model)) Apple AirPort Extreme Base Station (Simultaneous Dual-Band) (MC340LL/A). Since upgrading to this new AEBS, my TV will not connect via its internal Airport card. The TV will "see" my "Home-LAN" but always gives the error message, "Connection Failed".
    I have tried to Reset and Restore the TV, even the "Restore to Factory Defaults"! I have changed the security settings on my AEBS from an Open Network (no security) to WPA/WPA Personal, WPA Personal. I have changed the "Radio Mode" from "802.11a/n - 802.11b/g" to "802.11a - 802.11b/g". The TV will not connect! I now have it connected to my "Home_LAN" via Ethernet, and it works fine.
    Anyone with a similar problem and a suggestion or solution? Do you think the internal Airport Card is the problem? Thanks

    As suggested in another discussion area, (AirPort), I reset the AEBS to factory defaults. On the TV, I went to >Settings>General>Network>Configure Wireless>Wireless Networks. I could then see the generic "Apple Network xxxxx" on the TV. From my MacBookPro, I verified that I could connect to the TV by launching iTunes and noting that the TV was now visible in the "Devices" menu. Went back to the AEBS and ran through the "Setup" routine. I did NOT use the "Previous Settings" but instead, saved the old settings profile, created a new wireless network and new settings profile and enabled WPA2 Personal encryption. I then went back to the TV and went through the "Settings" routine again (as noted above). This time, after entering my WPA2 password, the TV connected to the network and problem was solved. Thanks.

  • Why does the new Dual-Band AirPort Extreme Base Station act as a proxy?

    The previous thread
    http://discussions.apple.com/thread.jspa?threadID=1531675
    has been archived and nothing came of it, but after testing, I'm certain that their findings are true.
    The Dual-Band AirPort Extreme Base Station (AEBS) with firmware 7.4.1 acts as a proxy for TCP ports 21, 554, and 7070 when NAT is turned on. This can be verified by using Nmap on any external server known to NOT have the ports open and having Nmap return that the ports are open. You can telnet to these ports to verify that they're "open," even though they are not on the server.
    This functionality appears to be undocumented and as far as I can tell, the only way to turn it off is to put the AEBS into bridge mode and having some other device do NAT further upstream.
    As a computer professional, this functionality extremely undesirable, particularly since it is not documented and doesn't have an "off switch." I wasted a bunch of time with one of my network engineers because of this, thinking that some network router was spoofing our server. I also wasted a bunch of my time trying to detect whatever "stealthy rootkit" had opened a FTP server and some other botnet related ports on our server, when in reality, it was simply my AEBS tricking me.
    Disabling NAT-PMP ("Enable NAT port mapping protocol") does not affect this.
    Is it too much to ask to have a checkbox in the "Advanced" section of the AirPort Utility to turn this feature off?

    Welcome to the discussions forum Michael Bennett2.
    Thanks for investigating this odd behavior.
    If you want your work to be noticed by those who can effect change, you'll have to tell Apple via their feedback link. It won't do any good to post it here.
