Aironet 1250 and AIR-ANT2430V-R

Hello,
I've just installed a Aironet 1250 and AIR-ANT2430V-R antenna.
I could do with some pointers on configuring the 2.4Ghz radio interface.
Role: Access Point
Goal: Blanket office coverage
Channel width: 20Mhz or 40+ ?
External Antenna Configuration: Enable
Gain: ??db
Currently I'm seeing speeds between 1Mbps and 144Mbps, with sporadic coverage.
I was expecting £900+ equipment to be better than the £10 D-link POE WAP currently installed! =]
Thank you in advance

Do you have the rp-tnc connectors fastened tightly?
How are you measuring the bitrate?
Also, have you tried using a tool such as iperf to measure actual throughput and not bitrate?
If you are running 802.11n rates on the 2.4 spectrum and plan to deploy more APs on the network, you will want to stay away from channel bonding.
We do not run 802.11n on the 2.4 side, only the 5Ghz side.

  • 1250 w/AIR-ANT2430V-R Which cable is antenna A - B - C or does it matter

    Hello,
    Please help I have read every doc on this AP and this antenna. there are three jacks on the radio labeled a - b and c. There are three cables on the antenna. which cable corresponds to the correct radio antenna label. Or does it not matter. Looking at the radiation patterns on the antenna I tend to think that it makes a difference. Thanks the info.
    Jason

    The main thing to consider would be that the center cable should be connected to the center jack. The others should not matter as they are the outbound antennae and in mimo the center antenna is the critical unit for phase differentiation. The phase shift mechanisim in the unit will take into effect the other 2 antennae and their position.

  • Unable to Connect to Cicso Aironet 1250

    My office just bought the Cisco Aironet 1250 and I am task to set it up. Right now, I am unable to connect to AP even when it is configured as Open Authentication without encryption. Tried using both laptops and our products to no avail. The same laptops and products are able to connect to other wireless routers So far, only my Linksys Wireless-G USB network Adapter is able to detect it.
    We are very puzzled by this because we are able to setup and connect to it initially. But when we try to reconfigure it to another setting, everything starts to fail. We have tried doing factory default.
    The AP is connect only to a Windows 2003 Server running DHCP and IAS. Appreciate if someone can help me on this. Thanks

          I have two buidlings acroos the street from each other.  I have two Cisco Aironet 1250 wireless AP's with the first one going in the main building with network backbone.  The Second AP goes across the street with the other wired network segment.  Both AP's have long range antenas 2.4 GHZ on top of each building.  I have configured the 1st one as the Root Bridge.  The one across the street is configured as non-root bridge.  I have both AP's configured with the same WEP key and also with the same SSID name with both set to broadcast it.   I am still unsure and confused as to how I get the non-root bridge to talk to and use the root bridge to get on the main network.
            1- It’s main to use the Root parent Mac address.
            2-  Is there another config that I am missing to get the signal? 
    Note: I still not getting any signal from the root although distance between root and non-root is 330m
    My root antenna is AIR-ANT24120 and non-root antenna is AIR-ANT1949 and attached files is my configuration files
    Thank you.

    1.  How are the AIR-ANT24120 and the AIR-ANT1949 installed?
    the AIR-ANT24120 is connected virtically on tower far 11m from the earth and AIR-ANT1949 is connected horizontally on tower far 10m from the earth
    2.  What is the distance between both APs?
    350 m
    3.  Do you have clear line-of-sight between the two?
    there is one tanker in the middle between them but it's far 7m from the earth
    4.  Is the two APs properly aligned?
    i think yes and changed the aligned many times without any news (I don't have any tools for alignment)
    5.  Which point are the antennas connected to?  Primary, Secondary or middle?
    I tried in the primary and secondary but never tried the middle antenna
    Thanks

  • Cisco Prime Infrastructure 1.2 and Aironet 1250 + VSS issues

    Hi,
    I  am new to the NCS implementations and configurations. I have one very  specific case with Cisco Prime Infrastructure 1.2 and autonomnous APs  and several issues with Cisco VSS on 6500 switches.
    So here is the version from Prime:

    Well  the issue what we have now is that access point has been added but its  not recognized by the NCS prime. I have tried all three versions of SNMP  but I get the same result. The SNMP configuration is valid since I use  the same for my switching infrastructure. When I enter "debug snmp packets" and "terminal monitor" I can see the SNMP communication between Prime and Aironet 1250 which is standalone.
    When  I switch to Lifecycle theme and go to Operate > Device Monitor  Center I see all devices I have added. The Aironet 1250 is reachable but  under collection status I get Managed with Warnings. When I hover over  with my mouse I get "None available".
    I  have successfully added my switching infrastructure in total, which is  operating perfectly for Catalyst 2960/3650/3750/4500 series but for 6500  under VSS I have some warnings. The device is recognized by the system  which is excellent and all is operational. I get the following errors  under Collection Status:
    feature_sensor
    SNMP request timed out
    feature_powerSupplyFanStatus-6k
    SNMP request timed out
    IdentityCapability
    The device is unreachable.
    feature_flashdevice
    SNMP request timed out
    sam_ipsla_feature
    The device is unreachable.
    What can be done to resolve these issues ? I have attached a screenshot of this particular issue. The affected access point is 172.16.165.241.

    Hi rajeeshp,
    Currently I am not allowed to upgrade it because of internal procedures involved in upgrading a specific piece of software (obtaining permissions from various departments). Is it free to upgrade from 1.2 to 1.3 or there is a specific charge for that.

  • 4 Aironet 1250's and a controller?

    Hi guys,
    I'm about to order a four Aironet 1250's and a 2106 Wireless LAN Controller. From what I've read, I'll need the controller to manage the APs if I want them all to offer the same broadcast domain and subnet, and offer roaming to the users. Often times what I read and understand turns out to have little to do with reality, so my question is, am I correct about this?
    Thanks in advance!

  • Antenna direction for Aironet 1250

    Hi,
    What is the recomended antenna direction for Aironet 1250 model? We have three antennas. And we have no choice but to fix the base device on the wall of our office. So the antennas are looking like coming out of the wall towards the office open space. All uses use notebook which is on the horizontal platforms of tables. Is this the direction / orientation correct of notebooks and aironet antennas. Or do we need to turn the antennas in the vertical direction.
    DO we have any best practises available fro antenna direction on cisco.com ?
    If yes please let me know the URL.
    Thanks in advance.
    Subodh

    You should have then vertical. There are antennas that are dipole that are not fixed position. This will allow you to have them in a vertical position rather than horizontal.

  • The difference between AIR-ANT5135D-R and AIR-ANT5135DB-R

    Hi,
    Anyone know what is the difference between AIR-ANT5135D-R and  AIR-ANT5135DB-R ?
    From the dynamic configuration tools for 1252 and 1242, AIR-ANT2422DB-R is inside one of the antenna option.
    However, I can't find it in the "Cisco Aironet Antennas and Accessories Reference  Guide"
    http://www.cisco.com/en/US/prod/collateral/wireless/ps7183/ps469/product_data_sheet09186a008008883b.html
    Inside the document there is only AIR-ANT5135D-R.
    likewise for the 2.4 GHz,  AIR-ANT2422DB-R is inside the dynamic configuration tools and not inside "Cisco Aironet Antennas and Accessories Reference  Guide"
    Any help would be appreciated
    Thanks,
    Richard

    Found the difference, AIR-ANT5135DB-R and       AIR-ANT2422DB-R are  non-articulating antennas.
    Thanks!

  • Aironet 1250

    I have an interesting problem. I have an aironet 1250. For months my wireless clients has been connecting with no problems. One day there was a power failure, don't remember making any chnages which I should of saved. After, all of my equipment rebooted with no problems. Now I'm seeing my 802.11N clients having connectivity problems. After 10 to 40 mins I believe they get logout, but the client don't get updated to this. The G and the B no problems. Some are Intel chip sets and some are apples base computers.

  • Aironet 1250 AP

    Will the Cisco Aironet 1250 (802.11n) only require an Firmware upgrade after it has been approved for use and gets past draft 2.0? Im thinking of purchasing for testing but want to make sure that being that its in its early stages that the code will only need to be upgraded once the standards have been created.
    Anyone know?
    Thanks!

    Hi Adam,
    Have a look at these answers from Cisco;
    Q. What is the procedure for upgrading radios in the Cisco Aironet 1250 Series Access Points once future technologies become available?
    A. The Cisco Aironet 1250 Series was designed as a modular and upgradable access point platform. When new radio modules become available, the old radio module may easily be removed and replaced in the field.
    Q. Will Cisco guarantee that the Cisco Aironet 1250 Series can be upgraded to support the final 802.11n standard?
    A. Cisco cannot guarantee that the current Cisco Aironet 1250 IEEE 802.11n draft 2.0 standard radio modules can be software-upgraded to support the final 802.11n standard. However, the modularity of the Cisco Aironet 1250 helps ensure that should the final 802.11n standard require a hardware modification, the impact will be limited to just the radio modules, and will not require a change to the access point. The Cisco Aironet 1250 Series radio modules are field-upgradeable and easy to change.
    Investment protection: The Cisco Aironet 1250 Series is a powerful, modular and upgradeable platform that provides support for the IEEE 802.11n draft 2.0 standard today. Platform modularity ensures a smooth migration path to emerging higher-performance wireless technologies and future advanced services.

  • Cisco Aironet 1250 basic setup questions

    Hi,
    I'm going to be three Aironet 1250's within a building.  There is not going to be a wireless controller, the AP's are all going to be standalone.  I am going to set them all up the same, with WPA2 wireless encryption.  My question is, is it important/beneficial to add configuration to the AP's so they are aware of each other (for roaming perhaps)?  If so, what is this technology called and could someone point me towards a section of a guide that could illustrate this?
    Or am I good with just configuring 3 standalone AP's as is.
    Any other pointers are welcome.
    Thanks!

    Hi,
    On Autonomous APs you can use Wireless Domain Services (WDS) technology which allows the APs to be aware of each other and make roaming faster withouth needing full authentication each time the clients move from one AP to the other.
    Basically you configure the same SSIDs on all 3 APs, then only one will act as primary WDS.
    The primary WDS will be responsible for the communication between the clients and the RADIUS server, and the infrastructure APs will simply bypass all the info from the clients to the primary WDS and vice-versa.
    Evenually you can configure standby WDS with different priorities so that in case of the primary WDS goes down, another AP assumes the role of active WDS.
    Configuration Example via AP GUI:
    http://www.cisco.com/en/US/products/hw/wireless/ps458/products_configuration_example09186a008059a559.shtml.
    In attach you can find an example of config using WDS and Infra APs. You will find example to configure open ssid, psk, and eap using WPA2.
    3 diferent vlans.
    Clients authenticate against External RADIUS Server and APs authenticate on local RADIUS for WDS.

  • Aironet 1250 Overlapping Channels

    Hi,
    In my LAN, I have always been used an Aironet 1250 for internal use and always work fine. Now, I added a 3com AP but both AP are not correct. When I turned off the AIRONET 1250, the 3COM AP settings works fine. When both are turn on, the 3COM AP loses connectivity all the time.
    I have heard about the overlapping channels in 802.11b/g networks.
    Someone could tell me what I could do for solving this?
    Note: Due to restrictions on my security lan, I could not use two SSID(using vlans) on my aironet 1250. This will be the best scenario, but it was not possible.
    Thanks in Advance,
    Fernando

    yes. The Aironet 1250 connects to a DHCP server in the range 10.150.x.x and the 3com AP connects to a range 192.168.1.x. The DHCP servers are in different places and there is no any possibility that they could overlap one and another.
    But I realized that the problem must be between the two access point because the 3 com AP got an IP Address from the range 10.150.x.x(it sounds crazyness but its true). Offcourse, soon the 3COM AP loses the connection.
    Tks you very much,
    Fernando

  • Antenna AIR-ANT2430V-R only for 1252 series??

    Hi,
    does any of you know why this antenna model (AIR-ANT2430V-R) can only be used for  1252 series???
    what would be the problem if I use it with 1262 LAP  ??
    regards,

    The antenna was specifically developed for the 1252 APs because at the time the only 802.11n AP cisco offered was the 1252. They now have the 1260 series and the 3500 series APs. The thing to be aware of with antennas is: 1. do they have the right connectors and 2. are the tuned to the right frequency. I agree with Leolaohoo that you can use these antennas on any of the Cisco 802.11n APs.
