Airport 802.11n issues

I have 4 macs and 3 of which cannot access the Airport extreme 802.11n.
The only one that can is the MacBook 10.5.4
I need to connect a g5 (intel) 10.5.2, PowerBook (PowerPC G4) 10.4.11 and MacBook Pro 10.5.4
Is this info helpful, or do you need to know anything about the airport card each comp has?
Can you point me towards some troubleshooting help?
Thanks so much!

"I need to connect a g5 (intel) 10.5.2" did not think Apple ever made this one has a B/G card not N
"PowerBook (PowerPC G4) 10.4.11" has a B/G card not N
"MacBook Pro 10.5.4" should be able to connect to N
Use Airport Utility and set your network for 2.4 GHZ N+B/G speed you will not get N speed at 5 GHZ your devices are mixed so the N peed will not be there.

  • Airport (802.11n) and WDS

    Hi,
    Does someone can tell me what "speed" will I get with two Airport 802.11N with WDS setup ?
    I alreday know that a WDS with an Airport 802.11N and an Airport Express or Extreme won't get better than the slowless one : 802.11g.
    Thanks

    You'll get 54mbit between the two airport extremes...
    Technically yes but the bandwidth available to any client is really only 27 Mbps since all data must make 2 hops and no other data can be transmitted during either hop. Other data can not be transmitted because both base stations are using the same channel.
    So if the client requested 54 Mb, it would take one second to go from AEBS_1 to AEBS_2 and then another second to go from AEBS_2 to client. Therefore the total bandwidth is:
    (54 Mb)/(2 sec) = 27 Mbps
    Don't know where you got 104 Mbps but if the clients were able to use that speed to connect to AEBS_2, the data would take .519 seconds on the second hop. The overall bandwidth would then be:
    (54 Mb)/(1.519 sec) = 35.5 Mbps
    Regardless of how you slice it, WDS makes a drastic cut on your available bandwidth.

  • AirPort 802.11n ... speed

    I just upgraded to 802.11n, but it seems much slower than the old AirPort g. Is this just my problem or does "n" work differently?

    I just used the AirPort Client Monitor to see what's up. Here is what I'm getting.
    Strength: -40dBm
    Noise: -90dBm
    A signal with a strength of -40 dBm and noise of -90 dBm would equate to a Signal-to-Noise Ratio (SNR) of 50 dB -- an excellent value for WLANs.
    SNR is the signal level (in dBm) minus the noise level (in dBm). In your example, a signal level of -40 dBm and a noise level of -90dBm yields a SNR of 50dB.
    The SNR, as measured from the iBook, decreases as the range to the base station increases because of applicable free space loss. Also an increase in RF interference from microwave ovens and cordless phones, which increases the noise level, also decreases SNR.
    SNR Guideline
    o 40dB+ SNR = Excellent signal
    o 25dB to 40dB SNR = Very good signal
    o 15dB to 25dB SNR = Low signal
    o 10dB to 15dB SNR = Very low signal
    o 5dB to 10dB SNR = No signal
    Transmit Rate: 52Mbps
    54 Mbps would be the highest possible bandwidth for a 802.11g wireless network ... so getting 52 Mbps would be excellent.
    To achieve 130 Mbps, the wireless network would have to operate at in either 802.11n only (2.4 GHz) or 802.11n only (5 GHz) with wide-channel disabled radio modes. To achieve 300+ Mbps, the network would need to be operating in the 802.11n only (5 GHz) with wide-channels enabled radio mode. In addition ALL wireless clients must be capable of either of these as well. Any "b" or "g" clients will impact the "n" network overall bandwidth performance.

  • Apple Airport 802-11n connection problems with Windows 7

    I'm basically a MAC user, but my son is trying to get his Windows 7 Toshiba laptop to connect to my Apple 802-11n wifi. It will see the wifi, but when clicked on my network the connection fails before I get to input the password. Yet neighborhood 802-11n connections get to the password screen. The lap[top is a Toshibe satellite L755-S5107 running Windows 7.
    I'm not very savvy on PCs, so I don't know where to look for versions of his software et al.
    Anyone familiar with such problems?

    Toshiba may be doing something different than other manufacturers, so your best bet might be a Toshiba support site.

    Not sure how much more help that we can provide on an Apple support site for Apple wireless routers.

  • Conflict with Neighbour using another Airport (802.11n)

    Hello
    I noted recently some slow down in my home wi-fi network and discovered that my neighbour installed a new airport extreme that might be confilicting with mine. I have tried to change channel (automatically set to 7) to 2, 3, 4, 9 and others. It partially solved the problem but if it works for a while, then the problem keeps coming back. I will go to his place tonight, please could you tell me what I should check ?
    Also while changing my configuration, I keep having the same error message coming back (on my airport extreme), that is error code -6722 or sometimes -32 or -6. Apparently this is a comon issue to many of you. Could you help me also on that one? Thanks a lot. Pascal

    I have now turned mine to channel 11 and it seems to work.
    I would expect that having both units assigned to the same channel would maximize the interference, not minimize it. But if it's working, I won't argue.
    However, while applying the changes, I got the error message -(6722). Also sometimes, error -(32)
    A Web search showed a number of reports of error -6722, but no one seemed to have an explanation. Sorry.

  • Airport 802.11n Disk - File Corruption!

    I'm seeing occasional file corruption when using Apple Disk. After copying files to an Apple Disk using a Mac mini via Ethernet, the files are not the same.
    myvideo.avi /Volumes/Adonais/Documentary/myvideo.avi differ: char 34439169, line 112648
    Copying the file again usually results in a successful copy. Copying to a Samba share on a Linux server is 100% reliable, suggesting it's not a network issue.
    I've tried two different USB enclosures with the same results. Both enclosures were problem free when directly connected to the Mac mini. The enclosure is connected to the base station with a Belkin hub.
    Mac mini   Mac OS X (10.4.9)  

    I've given up with AirDisk. The file corruption was too serious to ignore. I've plugged the HFS+ disks into the Linux server, mounted them (Linux hfsplus filesystem driver) and shared them using Netatalk. It's not quite as elegant but it's much more reliable.

  • WMM for AirPort Extreme (802.11n) - UMA T-Mobile not working...

    Is there any chance we'll see WMM (WiFi Multi-Media) in a firmware upgrade anytime soon? I noticed that according to the WiFi Alliance's website, when the AirPort Extreme was certified, it supported WMM!
    http://certifications.wi-fi.org/wbcscertified_products.php?search=1&advanced=1&lang=en&filter_company_id=&filter_cat egory_id=&filter_subcategory=&filter_cid=&date_from=&date_to=&x=30&y=18&selectedcertifications%5B%5D=33
    As an early adopter, I just got a BlackBerry 8320 from T-Mobile, which does UMA, so you can use the phone over WiFi. Works awesome with wireless routers that do WMM, basically doesn't work with my AirPort Extreme... As you might imagine, this is quite frustrating, as I have particular desire to have two APs, for basically no reason!

    I shot this across... let's see if anything comes of it:

    Subject: a rather pressing Airport Extreme (802.11n) issue
    i'm not sure if the person receiving this email will have any power (or will
    care enough) to do anything about sorting this problem out, but hey...
    better to try and fail than not trying at all, right?
    anyway... here goes:
    i am a die-hard apple user- heck, even a long-time stockholder- and recently
    bought an airport extreme (802.11n) router for my house. it worked
    flawlessly and i thought it was the best thing since sliced bread... well,
    until i picked up a UMA phone from T-Mobile.
    UMA is a service that routes your calls over WiFi. for some reason the UMA
    service worked everywhere except over my Airport Extreme base station. as a
    surprise, it even worked over my neighbour's older Airport Extreme (802.11g)
    connection.
    i swapped base stations (ie, brought his base station to my house, connected
    it to my network) and it worked. so, it is an issue that is clearly
    isolated to the new 802.11n base stations.
    thinking it was only me with this issue, i dug around the internet and found
    this discussion:
    http://discussions.apple.com/thread.jspa?threadID=1152014&tstart=15
    (if you want more, just google the keywords 'airport extreme UMA')
    obviously there's no resolution and people are getting quite peeved that a
    state-of-the-art base station can't do something than an older base station
    can clearly do. so, can someone please look into this?
    thanks!

  • Do my Airport Express just buy are with 802.11n?

    I using imac 2.4 GHz model 2008 which understand that it build in with airport extream 802.11n standard, isn't it?
    Also just buy Airport express but doubt that this AX is on which 802.11n or not?
    Because it shown only 802.11 a/b/g.
    And since I found software for airport 802.11n available for 1.99 US$, Do I need to install this software to be able to run 802.11n?
    Thank in advance.

    No, special software isn't needed. You have AirPort Utility already installed on your iMac and it is located under Applications/Utilities. Run AirPort Utility and go to Wireless and make sure you have an 802.11n mode selected (whether it is 802.11n only or 802.11n with b/g compatibility enabled).

  • Speed issue with WDS, Airport Extreme, and Airport Express 802.11n

    I have a Airport network set up using WDS and two airport base stations: an Airport Extreme 802.11n, and an Airport Express 802.11n. The Extreme is configured to be WDS main and is connected to my cable modem and other computers, while the express is WDS relay and acts as a switch.
    I don't actually have any wireless clients connecting to the express. I'm using it to connect a mac with no airport card to the network by plugging it into the ethernet port on the express. For the most part, it works, and the mac gets a network address and can access the network. However, the connection speed from the Express to the Extreme seems slower than it should be.
    Since both are 802.11n, and the Mac is plugged into the Express's 10/100 ethernet port, I figure the theoretical top speed that the Mac should be able to communicate with another device plugged into the Extreme is at around the same speeds as 100 mbps ethernet, since the 100 mbps ethernet connection should be the bottleneck in this case. In reality, the speeds are much slower: when I transfer files between a machine connected to the extreme (via ethernet) and my mac, the speed tops out at about 2 megabytes a second, if that.
    I looked in the Airport Extreme's logs, and it indicates that the Express is only connected at 54 mbps, as though it were a 802.11g Express. I have no idea why this is! Also, the only wireless communication is between the Extreme and the Express, so one wireless device acting as a relay for another (and thus cutting the throughput in half) shouldn't be an issue.
    Does anyone know why the speeds are so slow, and if there's anything I can do to improve them?

    Hello Brian Kendall. Welcome to the Apple Discussions!
    I looked in the Airport Extreme's logs, and it indicates that the Express is only connected at 54 mbps, as though it were a 802.11g Express. I have no idea why this is!
    That is because you established a WDS which only runs in 802.11g. Since you have two 802.11n base station, you would want to take advantage of the "Extend a network" feature available with these base stations.
    Here's a typical setup:
    o If practical, place the base stations in near proximity to each other during the setup phase. Once done, move them to their desired locations.
    o Open AirPort Utility and select the base station that will connect to the Internet.
    o Choose Manual Setup from the Base Station menu, or double-click the base station to open the configuration in a separate window. Enter the base station password if necessary.
    o Click AirPort in the toolbar, and then click Wireless.
    o Choose “Create a wireless network” from the Wireless Mode pop-up menu, and then select the “Allow this network to be extended” checkbox.
    o Next, select the base station that will extend this network, and choose Manual Setup from the Base Station menu, or double-click the base station to open its configuration in a separate window. Enter the base station password if necessary.
    o Choose “Extend a wireless network” from the Wireless Mode pop-up menu, and then choose the network you want to extend from the Network Name pop-up menu.
    o Enter the base station network and base station password is necessary.
    o Click Update to update the base station with new network settings.

    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.

  • Speed or Performance Issue with Airport Extreme 802.11n

    Background:
    Router 1: Linksys Wireless G 2.4GHz Router WRT54G (have been using for 1.5 years)
    Router 2: Airport Extreme 802.11n Base Station Model: A1143 (just arrived)
    Macs: Intel MacBook Pro & MacBook both Newtwork Adapters upgraded to 802.11 a/b/g/n and verified via "Netwrok Utility". The Netwrok Utility also displays the link speed at 54 mb under interface info. when the Linksys G router is selected and the link speed at 144 mb when the airport extreme n is selected.
    Observation & Issue:
    Currently, for testing both network routers have been used seperatly (connected directly via the cable modem) and speeds for each latop verified via http://www.speakeasy.net/speedtest/ and normal "human" usage web surfing observations via Safari. Results below:
    1. When using the Linksys G router both the MacBook and MacBook Pro appear to be performing well and responsive with little or no wait on graphically/media intense sites such as apple.com
    The speakeast.net/speedtest/ (using the NYC hub close by) downoad test displays 8MB to 10MB speeds
    2. On the otherhand, when using the Airpot extreme both the MacBook and MacBook Pro appear to be performing slower than usual with higher waits for image and page downloads.
    In addition, the speakeast.net/speedtest/ (using the NYC hub close by) downoad test displays 2MB to 3MB speeds. Lower than what we experienced using the older router.
    Request for advide or help:
    1) Is this normal? Assuming it is not, what esle can I look at that can help me determine the root cause. The Airport Utility does not offer much assistance in this matter.
    2) Thus far I have opted to revert back to my Linksys g router. However, before returning the product... any other adivce on a potential miss in the configuration or setup would be of great help.
    3) Other's experiencing the same?

    Contacted Apple Support (have an AppleCare account) tonight and the issue has been resolved with the caveat that I cannot have a mixed (g & n) radio mode on the same airport extreme base without significant loss of performance. These are the steps I was walked through to resolve my particular case:
    1) Verify that your hardware is indeed upgraded to use n (see steps in my original post)
    2) Open the AirPort Utility (new program that was installed from the install disc under applications/utility)
    3) Click on the Airport Extreme image on the right hand column to open the Airport Extreme settings
    4) Select the "Wireless" tab, then "Radio Mode" drop down and select 802.11n only (5 GHz)
    5) Select Update to apply new settings.
    Results:
    When running the speakeasy.net/speedtest I am seeing results that are indeed better. However, the test shows that the top speed lowers a bit and jumps back up unlike when I am on my old g router, which does not have such a jump.
    This test is not perfect but a good gauge. If anyone has any other ideas to test performance more accurately, please do let me know.
    Note: Only n enabled devices now work with the n router. I will keep my old g router as a backup and for my work pc laptop.
    Hope the above helps and thanks.

  • Airport Extreme 802.11n connectivity issues with Windows Vista

    I recently purchased the 802.11n airport exterme base station and set it up using my MacBook Pro laptop. During the configuration process I set the security to be WEP enabled since there are other computers on my network, one of which has only an 802.11b wifi card, that can only accept WEP security protocol. The set up worked great and I was surfing on the internet with my Mac in no time.
    When I go to connect to the 802.11n extreme base station with my Windows Vista desktop PC, I cannot get any type of connection. I re-entered the Network SSID to match that on the AE base station and re-entered the WEP enabled password.
    Is there a compatibility issue between the Airport Extreme Base Station and Windows Vista? I realize that the base station works on XP based PCs but not sure why it could not work on a Vista machine. Any help anyone can offer would be greatly appreciated.
    MacBook Pro   Mac OS X (10.4.6)   1.83Ghz Intel Core Duo

    Upon further review I determined the flaw with my earlier attempts to set up the airport exterme base station with my winodws vista desktop pc. I realized that I should not use a WEP key but rather a WPA key since the wireless adpater connected to my desktop is a wireless G enabled adapter that can handles WPA and WPA2 security.
    Therefore, no issues with Vista and the airport extreme base station. Works great.

  • Speed issue with TC and Airport Express 802.11n in WDS mode...

    Here is my problem.
    I replaced my older base station / Express duo with
    a new Time Capsule (1TB) and a new Airport Express (802.11n).
    I set up the network with the TC as base station running a WDS network (WDS main) and the Express is the WDS remote.
    When I check the wireless clients from the TC, I find my iMac running at 130Mbits and the Extreme at 54Mbits.
    No other wireless clients are connected to the network (I kept my slower network as a parallel one for my "older" Macs).
    The only other connected device is my Dish network DVR that is connected via an Ethernet cable directly to the Express.
    So my question is why does the Express not communicate at >54 speed rate with the TC?
    And, why does my iMac connect with 130 and not with 300Mbits?
    Any thoughts?

    Instead of using WDS, you should take advantage of the "Allow this network to be extended" option that is available for the 802.11n AirPorts including the TC. WDS only operates in the 802.11g radio mode.
    Here's the basic setup:
    o If practical, place the base stations in near proximity to each other during the setup phase. Once done, move them to their desired locations.
    o Open AirPort Utility and select the base station that will connect to the Internet.
    o Choose Manual Setup from the Base Station menu, or double-click the base station to open the configuration in a separate window. Enter the base station password if necessary.
    o Click AirPort in the toolbar, and then click Wireless.
    o Choose “Create a wireless network” from the Wireless Mode pop-up menu, and then select the “Allow this network to be extended” checkbox.
    o Next, select the base station that will extend this network, and choose Manual Setup from the Base Station menu, or double-click the base station to open its configuration in a separate window. Enter the base station password if necessary.
    o Choose “Extend a wireless network” from the Wireless Mode pop-up menu, and then choose the network you want to extend from the Network Name pop-up menu.
    o Enter the base station network and base station password is necessary.
    o Click Update to update the base station with new network settings.
