EA4500 - MBP Problem 802.11N / 802.11A

Hi Guys,
I've been using the EA4500 for almost a month now and I'm loving it. Fast & stable, but I noticed one problem. My Macbook Pro is not connecting via 802.11N but instead it is using the 802.11A. 
screencapture:
I tried trouble shooting this by using my other router Linksys WRTt310n and I noticed that my MBP is conencting to the 802.11n.  So basically it's not the an APPLE or MBP problem.
Is there any setting I should be checking out? 
Thank you very much in advance.

Hi hiptechboy,
You just made my day!  after setting up the QoS and turning on the WMM. Look what just happened...
Thank you very much mate! But can you please explain what  does WMM got to do with my connection problem with the 802.11N network? 
Thank you very much again guys!

  • 17" mbp no longer sees a 802.11a Linksys router...

    I have one of the early 17" MBP. It used to work with a old 802.11a (Linksys) router. Lately it doesn't see the router at all. I've reset the router and another Windows machine can see it fine. I didn't do anything funny other than apply patches and firmware upgrades. Any help is appreciated.
    Thanks

    Maybe its helpful you to know that the 802.11a standard wasn't totally supported by Apple at the begining (read http://www.appleinsider.com/article.php?id=1465) so probably those patches did change something.
    Have you tried different frequencies on the router?

  • Does photosmart d110a have 802.11a? If not, does it have 802.11n?

    Had it connected via b/g WiFi but it doesnt seem to connect with my new router even though ive checked all settings. The manual and cd are useless, and hp site's specs for this photosmart are useless. Appreciate your help if you can find out if it's 802.11a or n compatible.

    Hi,
    Did you ask this question yesterday ? Your printer is NOT networkable without buying more hardware:
    The following table lists connectivity options.
      Series                                                               USBWireless    NetworkWired Network (Ethernet)
    HP Photosmart e-All-in-One D110a Printer

    HP Photosmart e-All-in-One D110b Printer
    Yes
                No
                 No
    In short, it does NOT have wired and wireless adapter.

  • WLAN showing up as 802.11a/g but not 11n

    Using a wifi scanner like Metageek inssider or chanalyser, I'm seeing one of our WLANs as only 802.11a or g but not 802.11n like it should be.
    All the other SSIDs on that AP/controller are showing as 802.11n. I can't for the life of me think how this could be, but the scanner is showing the top data rate as 54Mbps. Connect to another SSID and it shows the upper data rates as well. 
    Any ideas why this would be? Typically this just happens to be our main SSID. Is it just the scanner interpreting things wrong? I've looked at the controller and the upper data rates are enabled for 802.11n as well as 40MHz for the 5GHz radio.

    It's WPA2/AES but WMM is not allowed (Cisco TAC had me remove that option to resolve a bug).

  • Does airport extreme 802.11a/c work with airport express 802.11n

    does airport extreme 802.11a/c work with airport express 802.11n

    "You can use the AirPort Express to extend the signal provided by the new AirPort, but the Express will not extend "ac" wireless since it does not have that capability. The Express will extend an "n" wireless signal if that helps."
    This is what I am trying to understand.
    So AXTRM w/ sep SSID for 2.4 (b/g/n) - call it SSID1 - and 5GHz (ac) call it SSID2 - WiFi Explorer confirms AC mode on 5G.
    Using an AXPRESS to extend - I have the option of SSID1 b/g/n *and* the 5GHz ac SSID2 in the pulldown (it sees both?) --> if I select SSID1, it also extends this same SSID in 5GHz (both showing b/g/n) >> so I now have 3 signals on SSID1 (XTRM 2.4G, XPRS 2.4G and XPRS 5G) b/g/n and one signal on SSID2 (XTRM 5G AC) ac
    If I select the 5Ghz ac SSID2 to extend - it prompts me "do you also want to extend (the 2.4GHz SSID1)?" --> select yes and I now have 2 signals for SSID (XTRM 2.4G & XPRS 2.4G) b/g/n and 2 signals on SSID2 (XTRM 5G 802.11ac & XPRS 5G 802.11 a//n)
    Is the 5G SSID2 actually being extended from the Airport Extreme to the Express?
    The reason I bring this up is I am having a lot of issues since iOS8 came out (especially on iPhone 6). Everything I am reading is pointing to when people have 2 AP's set to use the same SSID. When you walk to a part of the house where 5G 802.11 ac signal marginalizes, the phone does not immediately hand over to the 5G 802.11 a/n Airport Express.
    My thought was separate the SSID's but to me, if the Express can't extend 5Ghz from the Extreme, it's taking a step backwards. I am better off getting a more powerful router like an ASUS and going with one AP, drop the WiFi roaming altogether
    Any thoughts?

  • 802.11A

    Has anybody connected their MacBook Pro to an 802.11A router? The reason I ask is that currently my signal keeps on dropping out. I am using an Airport Extreme Base Station. The MacBook Pro wireless is much better then the Aluminum Powerbook which may be part of the problem. I am able to see more routers then before. Besides mine I see 2 Linksys Routers on channel 6, 1 Netgear Router on channel 11, 1 Unknown brand Router on channel 11 and a Microsoft Router on Channel 6. I have changed channels, turned off encription and tried Interference Robustness to no avail. I decided to connect to one of those Linksys Routers and no problems. So I am thinking that if I get a 802.11A Router I will not have any problem because the Frequency will be so much different then the others. PS I have not heard of anyone having any issues with the Airport Extreme Base Station and the MacBook Pro so I am inclined it is not a compatibility problem. Any thought on this issue would be appreciated.

    I have both a Linksys WRT54g Wireless Router and a NetGear WGU624 A.B.G Router (set up as AP) on the same network. My CoreDuo MacMini correctly displays the network selections (both 802.11a and 802.11g) and allows you to switch dynamically between the networks. Make sure you have SSIDs set up differently so you can distinguish which is A and G network. Also iStumbler96 is a UniversalBinary and correctly displays all the channel information correctly.
    The NetGear supports the Atheros 108Mbps link speed but Apple will only connect at a max of 54 Mbps while PCs with Atheros hardware connect at 108Mbps on both the A and B Network. No utility around yet that lets you unlock the capability to run at 108 Mbps on either the A or G network on the intel macs.
    Hopes this clarify.
    PS: Apple denies the capability this functionality is there but apparently uses Atheros driver code for OSX which make the process transparent. It is probably more trouble to remove the code than leave it alone. Throughput and range on the A network seems much better, probably because QoS (Quality of Service) is built into the link layer code. You can purchase a compatible NetGear PC card WG511U (A/B/G) tri-mode card and use both on PCs and MACs (PBG4 at present). The only driver available now for 802.11a for MacOSX is from Orangeware ( www.orangeware.com ) and install on a G4 Powerbook, then select A,B, or G networks. Orangeware is working on drivers for the MacBookPro. but you would need a PCI Express card. I don't have a MBP, but I understand that it also uses the Atheros AR5424 miniPCI card just like the intel MacMini, so an external A/B/G card is not necessary.
    Net of this story is that, Yes!!!, the intel macs have 802.11 a/b/g support built it and functioning.

  • AirportExpress 802.11b/g or 802.11a

    I have a quandary.
    My Macbook and Imac and wii system are not friends when connecting to my Airport Express.
    On settings 802.11n (802.11b/g compatible): My Wii and Imac works. Macbook dont.
    On settings 802.11n (802.11a compatible): My Macbook works. The Wii and Imac dont.
    Am i missing something. Is it the case im missing a simple setting? Please please help

    Oh, thanks, good to know.
    I had everything running great for over a week at one point, but now the problem has started without anything provoking it.
    So it looks like the problem is my Macbook not liking 802.11b/g. I know i sees the network and everything looks like it should, but it just wont work, however it will when i leave the room where the airport is.

  • WAP321-E-K9/max RF output power of 802.11a?

    Does the WAP 321-E-K9 (as 5GHZ frequency) supports the 802.11a?
    If yes, please specify exactly the output power transmission in dBm?
    Is it possible to have the 5GHZ frequency that not support the 802.11a? Because in the technical sheet of the WAP 321-E-K9 there is no specifications about the output power transmission (dBm) of the 802.11a standards ( only 802.11b/n/g are specified) ?

    Hi commercial7,
    I hope this helps:
    From the product documentation on the WAP321-E-K9 it appears that the WAP only supports 802.11b/g/n protocols. 802.11a (5GHz) is a legacy protocol that was outdated with the release of 802.11n (2.4/5GHz). While WAPs that use 802.11n are backwards compatible (support 802.11a/b/g devices), WAPs that use 802.11a won't support devices that use newer protocols. 
    According to the WAP321 Wireless-N documentation, transmitted output power: 802.11n @ HT20HT40, MCS15: 13 dBm
    Also according to the WAP321 Wireless-N documentation, receiver sensitivity: 802.11n: 300 Mbps @ -64 dBm. Since 802.11n should support 802.11a, you may want to check the hardware specifics for the 802.11a device you are trying to connect with.
    Does this answer your question?

  • VERY WEIRD!! Only 802.11a works

    I have a new AEn and I'm having a LOT of problem set it up.
    After hours of trying to figure out what was wrong, I finally came to the conclusion that only when I select "802.11n (802.11a compatible)" under "Radio Mode" does my wireless work.
    This leads me to the conclusion that only 802.11a is working on my AEn.
    And this is totally unacepatable, as this is the worst standard for wi-fi.
    Anyone has an idea?
    thanks.

    With the Airport Utility application under "Airport, Wireless" with your Radio Mode set to "802.11n (802.11b/g compatible)" set the Channel to 11 and see if that helps.
    I had this problem till I realised because my MacBook was brought in the USA it meant it shipped default with "Wireless Card Locale" set to "USA" rather then "Worldwide". By default the Airport Extreme will advertise on Channel 13, but becuase my Airport card is for USA it only covers Channels 1 to 11.

  • Access Point support 802.11a/g/b/r

    can you suggest me the access point which support 802.11a/g/b/r ?
    My problem is with 802.11 r. i am not getting clear idea about the wireless access point which will support 802.11r
    kindly suggest me the product

    There are no APs that support 802.11r yet. 802.11r is a standards extension to support fast secure roaming that was only ratified a month or so ago. It requires client device support and there are no clients that support it yet.
    If you want fast secure roaming, Cisco offers CCKM on all our APs and CCKM and PKC on all our controllers.
    I suspect though, that you may have meant, 802.11n, which is a higher data rate PHY/MAC standards extension. That is supported in the AP1250 series.

  • Cisco Systems vs "CSIRO" 802.11a and 802.11g infringed upon the '069 patent

    Hi,
    any news about Cisco Systems and the "CSIRO" 802.11a and 802.11g infringed upon the '069 patent ?
    http://www.buffalotech.com/products/wireless/
    Dear Customer
    As you may be aware, Commonwealth Scientific and Industrial Research Organisation ("CSIRO") sued Buffalo, Inc. and Buffalo Technology (USA), Inc. ("Buffalo"), for alleged infringement of United States Patent No. 5,487,069 ("the '069 patent"). Subsequently, CSIRO also asserted its patent against the entire wireless LAN industry, including, Microsoft, Intel, Accton, SMC and Netgear.
    In it's lawsuit against Buffalo, CSIRO claimed certain Buffalo wireless networking products compliant with IEEE standards 802.11a and 802.11g infringed upon the '069 patent. Buffalo believed at that time and continues to believe that there are no grounds for CSIRO's allegations of infringement. The United States district court, however, found Buffalo to infringe the '069 patent and enjoined the importation and sale of Buffalo's IEEE 802.11a and 802.11g compliant products.
    CSIRO's lawsuits are against the entire wireless LAN industry and could affect the supply of wireless LAN products by any manufacturer, not just Buffalo. The entire industry is resisting CSIRO's attempts to enjoin the sale of wireless LAN products. Recently, Microsoft, 3COM Corporation, SMC Networks, Accton Technology Corporation, Intel, Atheros Communications, Belkin International, Dell, Hewlett-Packard, Nortel Networks, Nvidia Corporation, Oracle Corporation, SAP AG, Yahoo, Nokia, and the Consumer Electronics Association filed briefs in support of Buffalo's position that injunctive relief is inappropriate in this case.
    During the period of time that the injunction is in effect (10/1/2007), Buffalo cannot offer for sale, sell, import, or use its IEEE 802.11a and 802.11g compliant products in the United States. A list of the products covered by the injunction is attached here . The injunction does not prohibit sales of pre-existing inventories of products by Buffalo's customers. In addition, Buffalo has secured CSIRO's agreement to permit the replacement of defective products under warranty. None of Buffalo's other products are currently affected by this injunction.
    While Buffalo believes that it will be successful in reversing the district court's decision and will obtain a stay of the injunction pending a decision on the merits, the Court of Appeals has not yet issued a decision. Should the Court of Appeals issue a decision staying the injunction, you will be promptly notified. After the stay is issued or a favorable decision on the merits is obtained, Buffalo will be able to resume the supply of IEEE 802.11a and 802.11g products
    Please rest assured that Buffalo continues to stand behind their products and will continue to support all of our loyal customers as it relates to product warranties, technical support and the like without interruption.

    I suspect after reading the patent and the litigation that you mentioned above, that the US District Court decision will be reversed as the patent appears to be very vague in its contsruction and verbage. Furthermore, the intent to hold the IEEE hostage on the ratification of 802.11n will not bode well in the court's eyes. If in fact the case is reversed, I believe that the members of CSIRO will be in danger of lost profits litigation from Buffalo. Stay tuned to this bat channel.

  • What's the difference between using and 802.11a and 5GHz only?

    What's the difference between using "802.11n (802.11a compatible)" and "802.11n only (5GHz)" modes on the Airport Extreme?

    802.11a gives you 802.11g speeds but using 5GHz (54mbps
    802.11n gives you 144Mbps (600 peak) at 2.4GHz or 5GHz

  • Does the 27" iMac wireless card support 802.11a and n

    does the iMac support the 5 GHz wifi format?  How about the N spec?

    I'm sorry but I don't understand this:
    the unit supports 802.11a channels but it doesn't pick up anything.
    Are you saying the iMac cannot connect wirelessly? And why would you be concerned that the very old 'a' standard may not be picked up? The latest standard is 802.11n, not a.
    http://en.wikipedia.org/wiki/IEEE_802.11
    So, is the iMac working wirelessly or not?

  • Connecting to 802.11a AP using WPA security - no go

    I have an AP that is set to 802.11a (5GHz) using WPA security and is set to hide its SSID. My iMac is connecting to this AP without any problems whatever frequency i set on AP, hide/show SSID. The problem is - Macbook does not show this AP in AP list when requested, if i select other and enter correct settings (ssid and WPA passkey) it says - connection timed out, AP does not show any signs that something even tried to connect to AP.
    the only resort is to use 802.11g when i can connect to AP without any problems.
    in Network utilities it shoes that it supports 802.11a/b/g/n
    hope i gave enough details.
    later today i will try to set WPA2 instead of WPA, also will try to set no security settings at all.
    any thoughts how to force it to connect to 5GHz AP?
    edit:
    forgot to say why i want to switch to 5GHz - the problem is - lately many 2.4GHz b/g APs popped up in neighborhood and started to cause latency/interference as some manage to follow me over frequencies i set up.
    Message was edited by: janiskr

    ok, setting to WPA2 solved the issue, because still, with WPA configuration i was not able to connect. allowing TKIP and WPA2 allowed macbook to connect. Also iMac changed the settings to WPA2 and it didn't matter that it had correct settings fot WPA.
    weird.
    maybe someone could point out how to set these things explicitly, so i can choose what settings are in use.

  • 802.11a/g/n optimizing for compatibility

    How to ensure maximum client compatibility and stability in 802.11a/b/g/n networks?
    I am running a Wireless network based on the WLC 5508 6 SW version, (with WCS mgmt) and 1142 APs. I would like a broad variety of clients, old G clients and new N clients to experience a stable connection to the network. I see Apple Macbooks, Lenovo-, Dell- and HP laptops in addition to HTC smartphones and iPhones on this network.
    I am having issues with some types of clients experiencing "unstable" connections. They are able to get a link for a variable ammount of time, then suddenly loose connection for a short period of time before reconnecting. These clients mostly use a third party SSL-VPN link over my wireless, therefore the loss of connection can be quite annoying. From time to time some of these clients seem to be flapping between access points but not seamless like roaming should be, rather with a short stop in connectivity before reconnecting.
    Previously we had a 802.11g Aruba wireless network in the same location. It had no such difficulties. This points me toward the config parametres in the controller.
    Which 802.11 b/g/n and WLAN parameters can affect this? I am looking for a document describing a best practice for setting up these parameters, or if someone here has input to a successful stable setup as the configuration guide only says e.g. "Enable if you want Aironet Information Elements"  does not help in deciding if I want this
    My WLAN is set up with WPA2/AES PSK
    and a guest network with web auth
    Examples of parameters:
    which Radio policy (bgn or gn)
    Aironet IE?
    MFP (disabled or enabled)
    QoS profile?
    can CCX location measurement affect performance?
    Which Data rates should be set mandatory/enabled/disabled?
    MCS (data rate) settings for 802.11n
    anything I have forgotten?
    The goal is:
    A simple, no hassle network providing maximum compatibility with different clients with a plus of 802.11n speeds for compatible clients

    Hey! I implemented your suggested improvements and the first impression is good!
    on 802.11a and b/g I disabled lower datarates, set 12Mbps to mandatory and the higher ones to supported. The instant improvement was the RTT measurements I made (previously they averaged at about 13ms (to an internet site) after the change they dropped to about 3-4 ms on average! I would say this is a very significant improvement!
    I have not been able to get any feedback from the user community yet :), but it sounds promising...
    I am still looking for some more insight into these issues, so if someone still has some ideas, please let us know!
