Airport Extreme Radio Mode

I have an Airport Extreme (older one that I believe doesnt broadcast dual radio mode).  I have multiple Apple devices (2 iPhones and 1 iPod Touch) that I would like to connect via WiFi.  When I have the wireless network broadcasting in b/g radio mode I can see and connect to my network but in that mode my Macbook connection is very slow (< 2mpbs per speedtest.net).  If I set Airport to n 5GZ or a compatible I get great speeds on Macbook (20 mpbs +) but cant access via iPhones/iPod Touch.
Is there anything I can do to have both access with mobile devices and still have decent Macbook connection?
Any help greatly appreciated.
Thanks,

Bob,
Thanks for the reply.  I have tried the 802.11n (802.11b/g compatible) mode.  When I use that mode I can indeed connect my iDevices however my Macbook experiences download speeds of < 2mbps (according to speedtest.net).  I use a real world test of trying to download Apple keynote from iTunes store under different radio modes.  Under N 5gh, N 2.ghz, or N (a compatible) the latest keynote which is 1.22gb will download in about 35 to 50 min.  When I use b/g compatible mode iTunes tells me it will be 7 hours.
Every once in a while I will set to b/g and test speeds and if I get lucky and see speeds of > 15 mbps and then leave it alone everything is perfect.  But it seems completely random.  I need to just keep trying, hope to get lucky and then hope it doesnt go away.
I was hoping that there was something in a deeper setting while under b/g compatible mode that would allow me to have acceptable speeds on Macbook.
Thanks,

  • Airport Extreme Bridge Mode Connection Drop

    Hi everyone,
    Hoping that someone will be able to help me. I have a one year old son who is now getting his hands into everything so a few weeks ago I decided to look at my options for networking my home iMac and External HD's.
    I am currently running a SKY (Netgear router) into an Airport Extreme set up in Bridge mode. I have turned off the SSID of the SKY Router and everything connects to the Airport. On the AIrport I have a USB hub attached which then has three external HDs attached to it. I know this is a lot, but I have not had any issues at all with data transfer with this set up.
    The issues I am having is that on average, once or twice a day the iMac will drop connection to the Airport. There is no patern to this as the iMac will drop connection while I have been working on the machine and also at times when it has been woken from sleep mode. There is then no physical way to restore the connection unless I restart the iMac. Even turning on/off airport does not fix the issue. If I try this, the iMac then seems to not be able to find any wirless networks, even those that are in the area of my home.
    I have turn off the the airport and ran the iMac simply connecting to the SKY router and have experienced zero problems, the issue only happens when I introduce the Airport Extreme.
    Does anyone know what might be causing the problem? I really need to try to get this to work so that I can eliminate the need to have the external hard drives attached physically to the iMac. In my home the router/Airport and drives are safely out of the way in a child proof area. I fear that if I have to introduce them back to being physically connected to the iMac they will no longer be safe from small hands!!!
    Many thanks for any advice.

    Unfortunately, you did not not include information about the operating system that you will use to configure the AirPort Extreme, so we would need that you be able to provide you with the correct steps to set up the AirPort Extreme.
    Bridge Mode would be the correct setting for the AirPort Extreme, but you will not have to worry about this if you use the setup "wizard" in AirPort Utility on your Mac or an iPhone / iPad since the wizard will automatically provide the correct settings for the AirPort Extreme.
    I'm not clear though on whether you want the AirPort Extreme to provide another separate wireless network or extend the existing Arris network. If you plan to locate the AirPort Extreme a room or two away from the Arris, then it might make sense to extend the Arris network, so you will have one "big" network that provides greater range.
    Whether or not the Arris will have NAT issues, we cannot say. This will be one of those times where you will not know whether something will work correctly until you try.
    If you are not in a rush to get the AirPort Extreme configured, temporarily power off the Extreme and get things working with the Arris modem/router and your Xbox.

  • Time Capsule / Airport Extreme client mode and alternatives

    I have three PCs on a boat.
    I want to create a wired Ethernet with shared internet access via wifi from a remote, land-based access point. I have no control over the broadband router at the other end (so putting an apple device at the other end is not an option).
    I read here:
    http://bc.whirlpool.net.au/bc/hardware/?action=hview&modelid=264
    ... that the Time Capsule supports "client mode", so I bought a TC today with fingers crossed.
    As soon as I configure the TC for client mode, it disappears off the wired Ethernet. In the instructions for the TC, there is a diagram showing the TC operating in what looks like client mode, but without any Ethernet devices attached. My interpretation is that if it does support client mode, it only does so as a wireless network drive and USB hub (ie no wired Ethernet). Correct?
    So, I think my options are:
    1. Plug a wireless gaming adaptor into the WAN port on the TC and use that to connect the TC to the remote broadband connection.
    or
    2. Take the TC back to the shop and get a gigabit router with aftermarket dd-wrt firmware to enable it to run in client mode, and then buy a gigabit NAS.
    Am I talking sense?
    Hopefully,

    Thanks for your reply...
    I am thinking of keeping the Airport Extreme as I have my PS3 and my Xbox 360 Elite connected to it by Ethernet and my Wii connected by Wi-Fi.
    So the Wireless clients are the iMac, iPhones / iPod Touch, Nintendo Wii and my Canon Wi-Fi printer... all of which necessitate the 802.11n (b&g compatible) setting on the AEBS
    I think that means that the Time capsule, Apple TV, Macbook and Airport Express will run on a throttled back 802.11n when ever there is no activity from the other devices... I am not entirely sure how the b&g compatible setting works.
    One of my favourite things about my setup is being able to use the iPhone Remote App to control my Macbook, Apple TV and Airport Express. Sadly, I have to have iTunes running on my computer as Apple Tv won't transmit its content to Airport Express which would be the ideal.
    Time Capsule has now been setup but I want to connect the HDD by USB and then use it as a Network drive, hopefully at 802.11n speeds. I will look into partitioning the Time Capsule but it has almost 300GB of Movies and I don't want to have to start again with all of that...

  • Airport Extreme 'Mixed Mode'

    Is there a mode to allow my iMac to connect via 802.11n while the XBOX 360 connects via 802.11g/b (I don't know which is faster..) at the same time? Or would I have to slow down the iMac and make it run with g/b (which ever is faster)?

    Where would I find out which model I have... I got it a while ago so probably the old one.
    The 1st/2nd generation 802.11n AEBS have the following Model#: A1143
    But if I had the new one, my 802.11n wireless clients could connect to the 5GHz radio without experiencing a slow-down?
    If you don't have any 802.11a clients, which also use the 5 GHz band, then yes they would not experience any "slow-down" caused by 802.11b/g clients.
    Would the 802.11n client experience the fastest connection possible?
    Yes. 802.11n clients can potentially achieve bandwidths of 300+ Mbps.
    And then my 802.11b/g client could connect to the 2.4GHz?
    Yes.

  • Best Airport Extreme Wireless Radio Mode with Old and New Macs and PC

    I'm running Airport Utility 5.3.2 and am running / connecting to the Internet with a new Airport Extreme 802.11n Gigabit Ethernet (the new squared off one) with "Version 7.3.2".
    In addition to my new MacBook Black (which has 802.11n, I have two other older Maxs that run 802.11b/g (and also a PC that has 802.11.b/g/n).
    Currently, the Airport Extreme's "Wireless" "Radio Mode" is set to
    802.11n (802.11b/g compatible)
    But, reviewing the Radio Mode menu, I see there are a number of choices that seem "faster" - 802.11n only (2.4 GHz), 802.11n (802.11a compatible) and 802.11n only (5 GHz).
    Can I set the Radio Mode to any of these other settings and still have my older Macs (and the PC) connect to the internet using this Airport Extreme? Or, do I have to leave my Airport Extreme Radio Mode set to what appears to be a slower speed 802.11n (802.11b/g compatible) setting to allow others to use this Airport Extreme Base Station?
    FWIW, I do have an older Airport 802.11g version 5.7 still connected and set up and the older computers can / could connect through that. However, I was hoping to give that one to a friend for their use elesewhere and wanted to have only one Airport Extreme set up at my house.

    "you'll use N+B/G at 2.4 GHZ."
    I guess you means that I should continue with my current setting on the Airport Extreme - which is "802.11n (802.11b/g compatible)" - if I want all my computers to access the web via the Extreme. Correct?
    I'm too much of a novice to try a "bridge" mode setup.
    However, your suggestion (I think) "It would be more reliable and faster speed if you could connect both routers to using ethernet" does give me hope.
    My Verizon Fios modem is actually a router. Indeed, I have my TiVo box connected to the Fios modem/router.
    If I connect BOTH of my Airport Base Stations to the Fios modem/router and then do the following:
    (1) set the newer "Extreme" Base Station to "802.11n only (5 GHz)" and
    (2) keep the older Base Station (running 802.11g) as is
    then my (and others') newer computer(s) with 802.11n can connect at high speed via the Extreme and older computers can still connect using the older Base Station.
    Correct?

  • HT4259 Cant extend airport extreme in bridge mode?

    My configuration is: Internet Cable Modem --> Airport Extreme (bridge mode) --> Airport Express (extend)
    My primary wi-fi base station (airport extreme) is set to bridge mode because the cable modem has the DHCP enable. Is it possible to extend it wirelessly with an airport express in other room of the house?
    Thanks!

    What is the approximate distance from the AirPort Exteme to the location of the AirPort Express?
    12 meters (another room)
    Distance here in and of itself should not be a problem.
    How many obstructions are there in the signal path between the AirPort Extreme and the AirPort Express?
    3 walls, 1 cordless phone
    A single wall can absorb anywhere from 10-20% of the signal or more depending on the type of construction. If the wallboard/insulation type has foil backing...as many walls do...even more of the signal is likely being absorbed.
    At best, the AirPort Express is picking up a signal that is likely 30-35% degraded. At worst, it is getting a signal that has degraded 70-80%, possibly more. As I said, the Express can only repeat the quality of signal that it receives.
    The effect of the cordless phone is unknown, but I would note that cordless phones are the main culprits that interfere with wireless network signals in a home.
    How many obstructions are there in the signal path between the AirPort Express and the general remote area where more signal coverage is needed?
    No obstructions (same room).
    Thanks for that info.
    I would suggest that you move the AirPort Express closer to the AirPort Extreme. by 5-10 meters. You may need to experiment with several locations to see if the performance improves in the remote area where you need more wireless signal coverage.
    Anything that you can do to eliminate or minimize obstructions in the wireless signal path will help. As an example, I cannot get an acceptable signal in my home in any area where the signal must pass through more than 2 walls.
    If you do not notice any significant improvement, your home is simply not going to work with a wireless signal extension setup....and you will need to consider connecting the AirPort Extreme and AirPort Express together using a permanent wired Ethernet connection. As you might imagine, there is no signal loss in a wire, so this type of setup will work much better than what you are trying to do.
    If I put the extreme and express side by side wirelessly (same room) is there a way to know if I am connected to the main or to the repeater?
    You will need a Mac laptop to check. There is no need to locate the AirPort devices side by side...they can be located where they are now.
    Locate your Mac laptop very close to the AirPort Extreme
    Hold down the option key on the Mac while you click on the AirPort icon at the top of the screen
    Look for the BSSID and jot that down
    The BSSID is the specific ID of the AirPort device to which you are connected.
    Now move the laptop very close to the AirPort Express
    Perform the same test
    If your Mac is connecting to the Express, you will see a different BSSID
    If you see the same BSSID as the AirPort Extreme, the laptop is still connecting to the AirPort Extreme....and the Express is not extending the signal at all.

  • Airport Express (2nd gen): Radio Mode & Channel Set-Up

    Hello,
    I am hoping somebody can help me with an Airport Express question.
    I have recently purchased an Airport Express (2nd gen) and iPod Touch (4th gen) to stream music. I experience connectivity problems when my neighbour’s WiFi is turned on. When their WiFi is on my iPod rarely can detect the Base Station and when it does detect it - it cannot connect. The Airport Utility cannot detect the Base Station either when their WiFi is on. Yet when they are away and their WiFi isn’t turned on I have no problems and the system works absolutely perfectly.
    I gather that I can change channels but I am looking for some advice on how to do this.
    In work (because I can open the Airport Utility there –as there is no interference) I connect using the Airport Utility I have found the following options:
    Radio Mode:
    5 GHz Mode:  Automatic mode, 802.11n (802.11a compatible) or 802.11n only (5 GHz Mode)
    2.4GHz Mode: Automatic mode, 802.11n (802.11g/g compatible) or 802.11n only (5 GHz Mode)
    Radio Channel:
    5 GHz Channel: Automatic or four channels (36, 40, 44 or 48)
    2.4GHz Mode: Automatic or choice of eleven channels
    There are dozens of combinations using Radio Modes (5 or 2.4 GHz, manual or auto, 802.11a compatible) and Radio Channels (4 options using 5GHz and 11 options using 2.4 GHz).
    Where should I start? Both radio mode manual and also manual channels? The possibilities seem endless!
    Can someone please help?
    Thank you.

    Hello, Tesserax,
    My apologies if I have breeched community etiquette in asking for your advice.
    I use a second generation Airport Express base station, Ethernet fed with category 6 cable, Radio Mode locked to 5 GHz for best data throughput, the station close to my iPad. The set up has improved YouTube video streaming performance significantly. No streaming freezing so far.
    Are my base station's WiFi Settings are correct?
    This is what I have done via iOS AirPort Utility -
    Edit > Advanced  > WiFi Settings > 5 GHz Name: AirPort Lounge -
    Radio Mode > Manual > Automatic Off > 5 GHz Mode > 802.11n only (5 GHz) > 802.11n only (5 GHz) ticked. Automatic off to allow access to 5 GHz only.
    Radio Channel > Manual > Automatic On > 5 GHz Channel 149. Automatic on to allow switching between 5 GHz channels.

  • Officejet Pro 8000 Wireless won't connect to my new Airport Extreme router

    I have owned my Officejet 8000 Wireless printer for about a year and had no problems with it.  However, my old wireless router wasn't fully Mac compatible so I couldn't secure it with a password.  I now need a secure network, so I bought an Apple Airport Extreme router in December.  
    I installed the router last night and it is working fine on my iMac, my PC laptop and my iPhone.  
    However, tonight I am trying to set up the Officejet Pro 8000 with no luck.  I've searched the posts here for 3 hours and am not finding the help I need.  Based on the other posts I've read, I am describing my situation below.
    I am trying to set up the printer from my Intel iMac with Mac OS 10.6.4
    I am trying to set up the printer with the HP Setup assistant that I just installed from the printer software.
    On the first wizard screen it tells me that my device is not configured (I agree)
    Then I ask it to configure for a wireless network.
    When I get to the Network Selection page, both my network AND my guest network (which I let my neighbor use) are shown on the list with full signal strength.
    When I click my network and then continue, the HP setup wizard freezes, and I have to force-quit it.  
    When I click my guest network and then continue, I get the message that my network is not within the reach.  (FYI, the printer is 10 feet from the router.)
    I have tried powering on/off the printer, router, and computer at all different stages of the process with no luck. 
    For my Airport:
    My radio mode is set to the most compatible choice
    MAC access control is not enabled
    Everything is WPA2 security
    "Use wide channels" and "Create a closed network" are UN-checked
    The channel is set to 11
    I am happy to try the "Add network client" thing I saw on other posts, but I don't think I have a printer front panel where I can start the "WPS" (don't know what that is) process.   If I do, it's not obvious and not in the HP manual.
    My ISP is Comcast (cable internet).
    I would really, really appreciate some help!  Please let me know what information I forgot to include and I will be happy to provide it.
    Thank you!
    This question was solved.

    First, you should be at 10.6.6, so please do Software Update (Apple menu) over and over until there are no more updates.
    From where did you get the HP software for your printer? Was it labeled as being compatible with 10.6?
    Finally, you will need to reset the printer so, let's do that:
    Press and hold the Power button, press Network button, (on some models, press the Wireless button ), two times, press the
    press the Cancel button three times, and release the Power button.

  • Using two Airport Extremes

    My home network is like game of Jenga. It works for years if I don't touch it. If I make any change, it comes crashing down.
    I bought a new Airport Extreme and am trying to use the old Airport Extreme to extend my wireless network. I can't get it to work.
    I have set the secondary Extreme to bridge mode and plugged it into ethernet on the WAN jack. I set it to "extend a wireless network" and select the same network name. But as soon as it powers up, it crashes the network and no devices can communicate.
    The configuration of the secondary Extreme shows "Connect Using: Wireless Network", but it's grayed out and I can't change it to Ethernet. I want to use ethernet.
    If I change it to "Create a wireless network" and give the new network a different name, it works.

    I'm still using Snow Leopard, Airport Utility 5.6.
    Ah, that's unfortunate, since it is incredbly quick and easy to configure things with the newer 6.x utility.
    First, I assume that you have already tested the Ethernet cable and connectons to make sure that they are working correctly.
    Perform a Factory Default Reset on the Old AirPort Extreme as follows:
    Power off the AirPort
    Wait a minute
    Hold in the reset button first.....and keep holding it in for an additional 9-10 seconds while you simultaneously plug the power cord back into the AirPort
    Release the reset button after the 9-10 hold period
    Allow a full minute for the Extreme to restart to a slow, blinking amber light
    Connect the Ethernet cable to the WAN "O" port on the old Extreme
    Open AirPort Utility, select the old Airport and click Manual Setup
    Click the Base Station tab under the row of icons to assign a name to the device, a device password, and adjust Time Zone settings. Leave the other settings "as is"
    Click the Wireless tab next to the Base Station tab and adjust as folllows:
    Wireless Mode = Create a wireless network
    Wireless Network Name = Exact same name as your "main" AirPort network
    No check mark needed in the box next to Allow this network to be extended unless you plan to add yet another device that will pick up and extend the signal from the old Extreme wirelessly
    Radio Mode = Automatic or same setting as the main AirPort Extreme
    Radio Channel = Automatic
    Wireless Security = Exact same setting as the main AirPort.....should be WPA2 Personal
    Wireless Password = Exact same password as the main AirPort network
    Verify Password
    Click the Internet icon
    Click the Internet Connection tab
    Connect Using = Ethernet or it might read DHCP
    Connection Sharing = Off (Bridge Mode)
    Click Update at the lower right of the window and allow the old Extreme to restart
    It would be a good idea to power off both Extremes at this point and wait a minute
    Start the "main" Extreme first and wait for a green light
    Start the "old" Extreme next and wait for a green light
    You should be all set now. Please post on your results.

  • Radio Mode "802.11n only", "802.11n (b/g compatible)" not available anymore

    Dear All,
    Today I was checking my AE config (7.3.2) with Airport Utility 5.3.2 (532.8) and I realized that there are no 802.11n modes available anymore... Usually it had two options, "802.11n only" and "802.11n (b/g compatible)". I cannot find also the frequency option (2.4 or 5GHz), probably because this should be available only for n modes.

  • AirPort Extreme After My Computer Sleeps

    When I wake up my MacBook from sleeping, something I try to avoid in the first place, I always lose my connection to the external HD plugged in to my AirPort Extreme.
    I'll still have a connection to the internet, but I'll be logged in as a "Guest" on my external drive. Is there a way to stop this from happening?
    I just upgraded to Leopard, but I was experiencing the problem prior. The AirPort Extreme is set for 802.11n.
    The only solution I've found is to go into the AirPort Utility and reset the AirPort Extreme. This gets to be a slightly annoying.

    I was browsing discussions, searching for a solution for exactly this problem. My cold comfort now is just - I am not alone
    I have an iMac and a MB (both 10.5.2) connected to Airport Extrem (mixed mode). Either of both computers may fall asleep and the Airdisk connection is broken for both computers. Internet connection is not affected. It is anything else but an accident - 100% reproduceable. The only way to recover is a restart of the Airport Extreme.
    I already wrote a feedback to Apple. I suggested to add a Restart-Button to the disk utility. To bad ...

  • Setting up Airport Extreme 802.11ac

    this is a continuation from this thread:
    Re: Airport Extreme Bridge mode
    I have added a new AX to my network.  The plan was to take the older AX and use to extend.  I also have an older A Xpress that I have re-purposed to get my audio receiver on the network, but did not want it to extend the network.
    After getting everything set up I started experiencing severe drops in internet speed and signal.  Looking into things I came across the above thread and followed the advice to set up without WAN connected and selecting double NAT rather than bridge.  At first I could not get to work (AX would not show on network: it was on ethernet, not wifi) but eventually got everything to go as described.  It now shows as being in double NAT mode but I am not convinced this is correct.  When I analyze the network via Airport Utility it sometimes shows that the Airport units cannot be found.  If I do this from my iPad, it only shows if I re-start the iPad.
    I know nothing about what Double NAT is or why this is supposed to correct the issue.  Just want some validation that this all makes sense.  Attached are some screen shots

    I am ready to take the next step properly setting up extender.
    OK, we can do that....but it would be a good idea to first review the upsides and downsides of the two methods to extend a network......extend using wireless and extend using Ethernet, since you say that you want to do this properly. As you might imagine, one method is much better than the other as far as performance on your network is concerned.
    Let's review extending using wireless first, since you indicate that this is what you might want to do.
    As you know, the wireless signal begins to slow down as soon as it leaves your "main" wireless access point.....the new AirPort Extreme....and it also slows down as it encounters any type of obstruction in its signal path to a wireless device.
    So, for example, let's say that the wireless signal leaves your new AirPort Extreme with an Internet speed signal of 50 Mbps. After the signal must pass through a few walls or a ceiling on the way to the location of the older AirPort Extreme that will be extending the wireless network, the speed of the signal might slow to only 20-25 Mbps by the time that it reaches the older AirPort Extreme.
    When the AirPort Extreme extends the signal using wireless, it can only extend the quality and speed of signal that it receives.....maybe 20-25 Mbps. Then the signal will slow down even more as it travels further away from the extending AirPort Extreme as it encounters any obstructions in the signal path.
    So, by the time the signal actually reaches a wireless device at the remote end of your house, that signal might be down to something in the 5-10 Mbps range, depending on the actual location where you install the AirPort Extreme that will be used to extend the signal.
    That is but one example.....your results will vary depending on distance, obstructions and construction type of the walls and ceilings, etc.
    In addition, a network that extends using wireless is more susceptible to picking up wireless interference from other sources.
    Bottom line.....extending using wireless is always a going to result in significant compromises and loss of the speed on the network.  Nature of the beast.
    Now, lets say that you decide to make the investment in installing an Ethernet cable from the new AirPort Extreme to the exact location in your home where you need additional wireless signal coverage. In this case, there is no signal loss in an Ethernet cable up to 300+ feet or about 100 meters, so the extending Extreme gets the full 50 Mbps speed and it broadcasts that signal.
    The result is that you will have much higher speeds on your network extending the signal using Ethernet.
    Have you made up your mind that you want to extend the signal using wireless, or can you consider extending using Ethernet?

    But, even if you are using the correct software to administer the AirPort Extreme, there is no setting for 802.11ac since it is always on by default.
