AP1042 802.11a/n/ac Radios down in the controller

802.11b/g/n Radios is up but 8021.11a/n/ac radio is down.   802.11a netowrk status is already enabled. Not too sure what may most likely be causing it to down?
Below is the output of "show sysinfo" from the controller and "show version" from the AP
Any input is appreciated.

This is the reason why your AP's 802.11a radio is permanently disabled.  Unfortunately, the Wireless LAN Compliance Status (06 October 2014) doesn't list old-model APs.  And this doesn't help anyone.  
You may need to contact your vendor and ask them politely if it's possible for you to replace your AP with the ones with the correct Regulatory Domain.

  • WLC 802.11a/n Radio Regulatory Domain Issue

    Dear All
    We are facing an issue with a customer where a Cisco 4400 Series controller is blocking the 802.11a/n Radio Interface of a 1250 AP. The radio shows as down on the controller GUI. The error message on the GUI is that the 'Regulatory Domain' is not supported. This can be seen from the attached screenshot. Also relevant parts of the WLC configs are attached.
    WLC: Cisco 4402  Wireless
    WLC Country: SA
    Device: Cisco Lightweight Access Point 1250 (LAP) is controlled through the 4402 Cisco Wireless LAN Controller (WLC)
    The operating system version of the LAP: c1250-k9w8-mx.124-18a.JA version of the WLC: Software Version 5.2.178.0
    The problem is that the controller shows that the 802.11a/n Radio Interface in Radio Slot # 1 is always down ,  the customer tried to manually 'no shut' the AP interface from the console and it worked , but obviously this solution would not work as the configuration cannot be saved (LW AP).
    Any help or pointers would be greatly appreciated.
    Regards
    Farrukh

    Hello
    This is sort of like a testbed setup, so can you tell me which country/reg domain I can set on my controller in order to make our access point work. There is only one AP connected to this controller.
    LAP:  AIR-AP1252AG-N-K9
    Also as per the guide, we can configure the country on a per-AP basis, would this be a viable option?

  • WiSM2 WLC 7.2 Maximum Allowed Clients under Global Parameters 802.11a/n b/g/n

    Hello everyone,
    Just loaded the 7.2.103.0 software onto the brand new WiSM2. Going throught the options and have found that under the global parameters for 802.11a/n, 802.11b/g/n radios is now the "Maximum Allowed Clients" option. The allowed setting is from 1 - 200 clients.
    Does that mean only 200 clients will be allowed to associate to the WLC on that radio at a maximum?
    Doesn't seems to make sense... I have the 500 AP license on this WiSM2... I know this option used to be an optional setting under a WLAN in previous releases.
    Any ideas?
    Regards,
    Sasha.

    Does that mean only 200 clients will be allowed to associate to the WLC on that radio at a maximum?
    As what Scott has responded, this means 200 clients per WAP.
    If you do exceed 200 clients per WAP (or whatever value you put in there) the clients will just get a nag and the system will let you in eventually.

  • 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.

  • 802.11b vs 802.11a & g

    Hi there,   any one can give me some idea on the best practise about the choosing the WLAN 802.11 protocols.
    I know that the in WLAN network, all device shares the same access point in half duplex, so using 11g, it would give us 45mbps to share than 11mbps (11b).  therefore, I would think it is good practitice to turn off 11b on all APs, but is there any disavantage by doing so? 
    also on the cisco Wireless Lan Controlller web interfarce,  Wireless --> 802.11a/n --> network, how to  setup the DATA RATES. by default the 1 to 5.5 mbps has been disalbed. 6 to 9 mbps are mandatory, then 12 to 54 mbps supported what is the difference and impact by changing those premeter.
    thanks.   roy

    I would think it is good practitice to turn off 11b on all APs, but is there any disavantage by doing so?
    You should know what your clients before you embark in this activities.  There are still some clients, such as old laptops or USB adaptors to medical equipments to brand new hand-held bar code scanners, that will read nothing but 802.11b and on 1, 2 or 5.5 Mbps data rates.
    The reason why these clients are still prevalent is because of the cost to purchase these wireless cards from storage houses. 

  • 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?

  • Unstable Wireless Bridge Connection via 802.11a(Radio 1) of Aironet 1242

    Hi,
    I'm going to setup up an AP 1242 in a remote area to support b/g client via a 802.11a bridge link (all using AP 1242).
    Before the deployment, I tested the configuration in a lab environment. However, I found the bridge link will come up a while and suddenly gone. Resetting the root AP or the non-root AP cannot bring the connection up again. Sometimes, when I shutdown the b/g radio (radio 0) of the remote AP, the bridge link will be established again. Following is the log from the root AP.
    Thanks!

    Thanks dmantill for reminding me to revisit the antenna and related stuff.
    As the setup is in a lab environment, the APs are put on a work bench next to each other, therefore, the radio output power was lowered.
    After adjusting the output powers, it works as expected.
    Thanks Surendra and dmantill.

  • Need to admin disable 802.11a radio from a few light weight access points

    Hi team,
    I need help to admin disable the 802.11a radio interface from a few lightweight APs. The operational status of these radio interfaces is down, so I am getting the following error when I try to disable them from the wireless LAN controller.
    (Cisco Controller) config>802.11a disable wds2.hyd.shaw.net
    This slot is not operational because Regulatory Domain Check has failed! Unable to disable the Cisco AP.
    Could you please let me know how I can administratively disable the 802.11a radios on these APs? Please let me know if you need more details here.
    Regards,
    Swati

    The two previous posts are correct: the regulatory domain is probably not allowing radio a to be enabled.
    To be sure about this you can go to GUI of the wireless LAN controller > Wireless > Country. Here your country (or region) should be selected. Then depending on the access points that you have they may or may not join or turn on the radio. Per example if you have an access point from Europe (like AIR-AP1131AG-E-K9) then you will have a conflict if only the “America” regulatory domain (-A) is selected.
    Here is a link with a list of products and their regulatory domain that might help:
    http://tools.cisco.com/squish/648C8
    What you can do here is to simply allow the regulatory domain that the access point needs and you should not have any problems.
    IMPORTANT NOTE: If you change the regulatory domain and use an access point that transmit at certain channels and frequencies that are not allowed (illegal) in your country (region) you may have legal implications.
    I hope this information helps you with your concern.

  • All of the 802.11a performed down so many time

    Hi all:
    I encounter a problem on mesh wireless system. All of the 802.11a on RAP are "administritivity down" after few hrs or mins of startup. 
    After i check the "show controller Dot11radio 1"  it shows "Last radio rest code : 49"
    Could some one help me on this?   My country code is Saudi arabia.  And Both 802.11a/n and 802.11 b/g/n

    1. I found there are 2 frequencies wild in the list, 20hz and 40 hz, which one is better ?
    > 40mhz will combine two adjacent 20mhz channels, so in your case maybe 20mhz
    2. I check the country code from the list, that Saudi is in -E zone, how to move to -M ?
    > YOu can add a country code on the WLC, but you can't change an access point contry code
    3. In 802.11a TPC option, i found 2 options. one is coverage optimize V1 , another is interference optimize V2.  Base on my current situation, which one is better ?
    > DO not use v2
    4. I found some channels have heavy radar signal interference, how can i exclude them to channel list.

    Hi Jeff
    I copy the configuration of the bridge. This is a new bridge that I setup as a role non-root bridge. with the new default configuration, as soon as I changed the role to non-root bridge, the 802.11A interface is down and disabled. Is it normal operation and how do I enable it back? any helps I am really appreciated that

  • RRM misconfiguration on 802.11a/n radio

    I am working on tunneling a wireless network with the following components:
    wlan-controller-14-4 impa-wireless4 --> AIR-WLC2106-K9
    wlan-controller-14-2 impa-wireless2 --> AIR-WLC2106-K
    11 AIR-LAP1131AG-A-K9
    10 AIR-LAP1252AG-T-K9
    They are geographically distributed on four floors in the same building.
    Controllers and APs have the same sw version respectively.
    I have configured RRM feature on both 802.11 a/n and 802.11 b/g/n
    RRM feature on 802.11 b/g/n is working fine.
    RRM feature on 802.11 a/n is unable to set different values for power conveniently.
    All 1252 APs have been set to power equal 1.
    Six Aps have been set to channel 149 even if they are neighbors (same floor or on correspondent position on other floors)
    debugging client mac 50:cc:f8:86:80:7e I have gotten:
    debug mac addr 50:cc:f8:86:80:7e *dot11a: Apr 07 16:39:36.537: Airewave Director: Processing Interference data on 802.11a AP 58:8D:09:1E:33:B0(1)

    Any idea?

    Hello
    This is sort of like a testbed setup, so can you tell me which country/reg domain I can set on my controller in order to make our access point work. There is only one AP connected to this controller.
    LAP:  AIR-AP1252AG-N-K9
    Also as per the guide, we can configure the country on a per-AP basis, would this be a viable option?

  • WLC 4404 - Not able to see the 802.11a/n AP summary details

    Hi Friends,
    I have a query related to wireless. I have multiple WLCs in my network. Recently I observed that in one WLC, in monitoring page while we checking the access point summary information, I can see in 802.11a/n Radios, 8 APs are down. And I tried to see those details by clicking the ‘detail’ option over there, but no result was displaying. Same I have checked in ‘Wireless’ tab as well but the result was same. We have total 69 APs associated with this WLC. AP Models which are associated with this WLC are AIR-LAP1231G-A-K9 & AIR-LAP1242AG-A-K9. Firmware version running in the WLC is 7.0.235.3 which is recently upgraded.
    Then I logged into multiple WLCs for checking the same. All these WLC are running with 7.0.116.0 code. In some APs I am able to see some AP information which is down for 802.11a/n Radios, for eg: if I have 18 APs down in a/n radio I can see 7 AP’s details. But can’t able to see all the AP information. For 802.11b/g/n Radios it is perfectly fine. And in these WLCs we have AIR-LAP1262N-N-K9 model also associated.
    And one thing I noticed here is the number of APs that I can see the details is exactly same as the number of AIR-LAP1262N-N-K9 model APs associated with that WLC.
    So can anyone confirm that the other 2 models won’t support a/n radios (hardware limitation) or is it any kind of bug in the firmware.
    My WLC models are AIR-WLC4404-100-K9 & WS-SVC-WISM-1-K9
    Thanks in advance for your time and response
    Regards,

    Hi Leo,
    I am not able to identify the AP which are down for 802.11a/n radio :( (we are not using a/n radio in this location, that is why 8 out of 8 are showing down).

  • AP radio down (1010)

    hi all,
    here is the log:

    3 Thu Feb 7 01:59:36 2008 AP Associated. Base Radio MAC: 00:0b:85:8e:ba:80
    what is the problem ?

    Hi Okan,
    The problem is that there are 2 different Country Codes being used "The regulatory domain configured on it '-E' does not match the controller's country code: Turkey"
    A mismatch in Country Codes will cause this issue :(
    You will need to use at least WLC code 4.1 version or change out the AP. Have a look;
    Note Controllers running software release 4.0 or earlier do not have the ability to control access points in more than one regulatory domain.
    Configuring Country Codes
    Controllers and access points are designed for use in many countries with varying regulatory requirements. The radios within the access points are assigned to a specific regulatory domain at the factory (such as -E for Europe), but the country code enables you to specify a particular country of operation (such as FR for France or ES for Spain). Configuring a country code ensures that each radio's broadcast frequency bands, interfaces, channels, and transmit power levels are compliant with country-specific regulations.
    Generally, you configure one country code per controller, the one matching the physical location of the controller and its access points. However, controller software release 4.1 allows you to configure up to 20 country codes per controller. This multiple-country support enables you to manage access points in various countries from a single controller.
    Guidelines for Configuring Multiple Country Codes
    Follow these guidelines when configuring multiple country codes:
    The multiple-country feature is not supported for use with Cisco Aironet mesh access points. If a mesh access point is already connected to the controller, multiple-country configuration is rejected. If multiple-country support is configured, mesh access points are not permitted to join the controller.
    When the multiple-country feature is being used, all controllers intended to join the same RF group must be configured with the same set of countries, configured in the same order.
    When multiple countries are configured and the radio resource management (RRM) auto-RF feature is enabled, the auto-RF feature is limited to only the channels that are legal in all configured countries and to the lowest power level common to all configured countries. The access points are always able to use all legal frequencies, but non-common channels can only be assigned manually.
    Note If an access point was already set to a higher legal power level or is configured manually, the power level is limited only by the particular country to which that access point is assigned.
    When multiple countries are configured, the 802.11a network is disabled for all countries if any country does not support the 802.11a radio or there are no common channels on the 802.11a radio.
    You can configure country codes through the controller GUI or CLI.
    Here's how;

  • AP is unable to associate. The Regulatory Domain '-E' configured on interface '802.11a' does not match the Controller Regulatory Domain '-C'

    Hi,
    There are three different types of APs associated with controller and working fine.
    1.       AIR-LAP1252AG-E-K9
    2.       AIR-LAP1522AG-E-K9
    3.       AIR-CAP1552E-C-K9
    WLC is AIR-CT5508-K9. Software version is 7.4.100.0. Field Recovery Image is 7.0.112.21. Firmware version is FPGA 1.7, Env 1.8, USB console 2.2. WCS is 7.0.240.0 for Windows.
    WCS is sending alarms for AIR-LAP1522AG-E-K9:
    Message: AP is unable to associate. The Regulatory Domain '-E' configured on interface '802.11a' does not match the Controller Regulatory Domain '-C'.
    Before Controller was 7.2.4 (not sure).
    Country configured on WLC is AE and shows -CE regulatory domain. Mesh APs are also associated.
    I believe this Critical alarm should not come.
    how much is this alarm important? What should be done to resolve this?

    Typically you still need to make sure that the country codes are indeed configured on the WLC. Thing can change when you upgrade code as standards might of changed and regulations also. If your AP's are functional, then you should be okay and I wouldn't worry too much about it, but if after the upgrade, the WLC complains about country code stuff, then you just need to verify that the AP's country code is defined on the WLC. May times the AP will not join and if it does join, the radios might be disabled or in a down status.
