Cisco aironet 1200 Series access point dropping clients

We are having an issue where our Cisco Aironet 1220 Series AP is constantly dropping clients. We have 3 APs mounted on a single tower, all out of each others range and freq. There are approximatly 30 clients on each AP. We are noticing an increase in dropped customers (up to 20 at a time). ANy suggestions? This only became an issue in the last few weeks, and nothing major has changed.

Hi
Even I was facing almost the same kind of problem. But in my case it was wired clients to the workgroup bridge 350.
I had done lot of testings and reading at that time to resolve this problem.
However in your case I feel your problem can be resolved by keeping the option "Reliable multicast for Workgroup bridges" disabled in the APs under dot11radio interface settings. This is possibly because the radios cannot associate to more than 20 clients at a time if the option is in the enable mode.
You need to keep this option enabled in a root bridge when you have problems of dropping the wired clients to the workgroup bridge.
By keeping this option enabled, you are actually asking the Root bridges to consider the Workgroup bridges as Infrastructure devices and not as clients thereby making the roots to send all the multicasts to the WGBs. However in that case it losses the efficiency of associating more than 20 clients.
Let me know if this resolves your problem.
Regards

  • Configuration of cisco aironet 1260 series access point..??

    i hv a cisco aironet 1262n access point and a normal router(without wlan)  with a broadband connection
    now i want to use my access point as a wifi hotspot 
    but i am not able to access it, through web browser
    i dont know how i connect wires so that i am able to access "  AP access page" and also i forgot its IP address too so can u pls tell me how do i reset it to default 

    Your AP is most likely loaded with a controller-based IOS.  You can easily convert this to autonomous IOS.

  • Cisco aironet 1310 Outdoor access point

    I am looking at outdoor access points, I want to stick with Cisco aironet, we currently have 6 of them that are 6 years old and running great, one has had a problem because of humidity, dried it out and relocated and we are good again.
    I was looking at the Aironet 1310 Outdoor access point, but I can't find much information on it.  I am looking to see how many SSIDs can be setup, we currently have 2 one private, and one public, this is done with VLANS.  I am also looking at finding out about the power injector, it converts to coaxial cable, it has 2 RJ-45 and 2 Coaxial, does this mean if we get 2 access points, then I only need 1 power injector?
    Thanks for any help you can give.

    Rusty:
    AP supports up to 16 SSIDs to be configured.
    Multiple SSIDs with VLANs configuration is done almost the same way you do with current Aironet APs.
    see here: http://tiny.cc/0qwnkw
    You also need one power injector per AP. Each AP should use it's own power injector.
    The two coaxial output in the power injector both are used to be connected to the AP (see below image).
    The RJ-45 connectors in the power injector one of them is for Console connectivity and the other for network ethernet connectivity.

  • Symbol Netvision Phone w/Cisco 1200 series Access Point

    I am running 802.11b access point my phone can associate and get an ip address from my call manager but I keep getting "not registered" "registered". I and then I lose association to the access point. I have 2 vlans on one access point one for voice and one for data. Please let me know if someone has a work around or a fix.
    Stan

    Stan,
    Sounds like you have an interference problem.
    What did your site survey show up in terms of other AP's and overlapping coverage areas ? Try a new channel that has the 2 channel separation from other busy channels and maybe even try a new/better placement of the AP
    effectivly what you have now is the equivalent of pulling out the cable and plugging it back in constantly on a standard IP phone this means you will not be able to make calls
    What firmware you running on the AP ?

  • Image Recovery for Cisco Aironet 1300 Outdoor Access Point

    We purchased two 1300 APs for outside. There is a new release for the image that we wanted to use so, we have the latest security updates. We downloaded, logged onto the access point just fine, but the image never took. After four hours with a direct connection, it was still going and this morning we came in and it just keep rebooting. Our network guy states it looks like a corrupt image. We can barely do anything and since there is no "mode" button like the earlier models, I have not found anything on web sites or forums to help us reload a good image to the access point. I would appreciate any insight someone has and/or where to look for this. I logged on and downloaded about every manual on the 1300 I could find, but have not found a good way to fix this. Not even the upgrade tool will connect since it just keeps rebooting.

    Hi Bruce,
    Because (as you correctly noted) the 1300 does not have a mode button you could try this method;
    Complete the steps in this section in order to reset Cisco IOS Software-based bridges:
    If the privileged command prompt ap# is available in the CLI, the write erase command and the reload command erase the startup configuration and reset the unit.
    If the GUI is available, choose System Software > System Configuration. Press the Reset to Defaults button.
    Aironet 1300 Series Bridges do not have a MODE button to reset the AP to factory defaults. So, if neither the GUI or CLI is available with sufficient privileges, complete these steps to delete the current configuration and return the entire bridge settings to the factory defaults using the CLI.
    Open the CLI with a Telnet session or a connection to the bridge console port.
    Reboot the bridge by removing and reapplying power.
    Allow the bridge to boot until the command prompt appears and the bridge begins to inflate the image.
    Press ESC when you see lines that are similar to these on the CLI:
    Loading "flash:/c1310-k9kw-7mx.v122_15_ja.200040314-k9w7-mx.v122_15_ja.20040314"
    ...#############################################################################Note: In order to access the boot loader, you must press ESC twice. But this action depends on the terminal-emulation software that you use.
    Messages that are similar to these appear:

    After the bridge reboots, reconfigure the bridge with the web browser interface, the Telnet interface, or Cisco IOS Software commands.
    Note: The bridge is configured with the factory default values that include:
    The IP address, which is set to receive an IP address with DHCP. If you do not have a DHCP server, you can access the bridge using the default IP address of 10.0.0.1 using HTTP/HTTPS or Telnet. Once you gain access to the bridge via Telnet or GUI, you can modify the IP address of the bridge.
    Note: This default IP address of 10.0.0.1 becomes available only for a short period. So, make sure that you assign your own IP address to the bridge within that period of time.
    The default username and password, "Cisco".

    One other thing, be careful with the new IOS that you aren't loading a LWAPP Recovery Image. (it almost sounds like what may have happened)

  • Cisco Aironet 1200 series AP's...

    Hi,
    The wireless at one of our remote sites was working fine until there was a problem one week back. Just for introduction we are using the following setups for wireless:
    independent wireless access-points whihc connect directly to the Cisco switches most 2950's..
    We have three vlans in LAN, vlan1 (for user - LAN), vlan-4 (for wireless users - EAP auth with MS-IAS s radius) and vlan-5 (for wireless scanners - MAC auth).
    All the AP's are 1231G series of devices.
    These AP's are connected to the switchports with a trunk, dot1Q enabled, vlan-4 as native vlan.
    Suddenly one day, 12 out of 15 AP's went offline, meaning: we were not able to ping any of them except 3 which were working fine. When checked at the switch we were able to see all 15 of them as CDP neighbor of the switches, even the ones which were not able to be pinged on the network. We were not able to ping them neither from the local L2 switch (IP on vlan-1) nor from the site router (default gateway of all the local subnets).
    I took the console connection of one of the not-working AP, it does not show any particular log or message. The Fastethernet0 port was UP/UP. I was not able to ping AP's default gateway. When I rebooted the AP, it was pinging from the network for about 2 mins and after that it was again off-network, not pinging. When the AP was reset to factory default, it was pinging fine for a long time, without any problems. When we put in the OLD configuration, again it was off-network, not pinging.
    Now, here is the surprising element for me! After 3 days of struggled troubleshoooting, remotely, onsite engineer changed the vlan allowed on the WAP connected trunk switchports (ie switchport trunk allowed vlan 4,5) i.e previously we were allowing 1, 4 and 5 vlans on the trunk, now he is allowing only 4 and 5. As soon as he made the changes, all of the not-working 12 WAP's became online one by one (as and when config change made on the trunk). Just to make another test and to make sure, I tried to allow all the vlans again and guess what the WAP was again off-networ - not pinging.
    Now my question is: Why it was all working fine for more than a year and then suddenly one day 'something' happened which caused the 12 AP's to behave abnormal while 3 of them were still working good.
    Is there any technical theory which can explain such type of behaviour?
    Thanks in advance,
    Gaurav

    Gaurav,
         If you have the ability to, I would put on AP back to the "non-working" scenario.  then check the ARP table to see if you are getting a duplicate mac or IP address.
    HTH,
    Steve

  • Specific OID for A radio modules on 1200 series access points

    Is there a specific OID for A radio module cards of the following type:
    Flap - AIR-RM21A-A-K9
    Dipoles - AIR-RM22A-A-K9

    No switches in Cisco's current product line provide enough power to support both radio modules in the 1200 series. The (now optional) power injector for the 1200 will provide enough inline power for both radios, if that is an acceptible option.
    Cisco has plans for several switches that will be able to provide inline power to both radios, but I am not aware of ETA's on these.

  • Aironet 600 Series Access Points

    Hello all.
    I am wanting to setup a wireless environment in my small chuch (obviously on a small budget ) and I was thinking about using 8 Aironet 600 APs with a 2504 controller.  Does anyone see any problem with that?  I am not looking to setup a secure tunnel/VPN anywhere, I just want wifi to be available for anyone on enterprise level equipment throughout the facility.
    Thank you.
    Jay               

    The AP 600's are for OfficeExtend and will not work for you. I would look at the AP 1602 or the lower end AP 702. Those will work for you.

  • Cisco Aironet 1240 AG Access Point - configure Mac Address using Telnet

    Hi there,
    I’ve got a problem hopefully someone can help me with. I have the above mentioned AP and it is configured, working well and providing wireless access to several laptops on our domain.
    The thing is I can’t get access to the web-based interface to add new laptops Mac addresses to the AP as I currently have them secured with local list Mac address authentication but my user name and password when entered in the web browser login dialog box won’t allow me in although strangely it does allow me to login using the same credentials when I telnet into the AP.
    Does anyone know why I can’t get logged in using the web interface even though the user name and password does appear to be correct as I can telnet in? Also if you have any suggestions how I could sort this without having to perform the password recovery procedure, as I don’t want all the config on the AP wiped and want to avoid having the set the whole thing up again.
    As I workaround if anyone knows what the commands are to allow me to add the Mac addresses of the new laptops so they are added to the local list Mac address authentication list so the new laptops are secured that would be great.
    Thanks in anticipation,
    Tony

    Your AP is probably configured to use the enable secret as the password. Try entering nothing for the username, and enter your enable secret for the password ('Cisco' by default).
    If that doesn't work, post your running-config and we'll be able to see why it's doing that. It's a standard configuration, and no worries because wiping the AP won't be necessary since you can successfully Telnet in.

  • Cisco Aironet 1100 series wireless access point software update!

    Hi,
    I have a wireless network using 2 cisco aironet 1100 series access points.
    From time to time I have problems with connecting a device (Laptop,PC,)to the wireless network.There are onther wireless netwotk that operate around and might be using the same channel.Someone else created the wireless network and I do not know how to access it now to check the configurations on change something.
    I cannot conncet my iPhone to the network and I beleive that a software update might solve the problem but I do not know how to do it and where to download it from.
    1. How can I update the software and where from?
    2.How can I ensure that thare are no interferences and conflicts?
    3.How can I ensure that no onther wireless network around is using the same channel?
    Thank you in advance.

    Sounds good to me. Are you having problems?
