Aironet 1100 as repeater: radio disabled!?!

I followed the directions according to the configuration guide 12.3(8)JA but the repeater never connects to the root AP and I notice the radio is "disabled" after setting the AP in repeater mode and it will not let me enable it. Any ideas as to why I cannot get the two Aironet 1100 AP's to connect and why the radio would be "disabled"?

I have no security in place and the SSID are the exact same. I have the AP's about 15 ft apart so the coverage should be fine. The parent mac address is correct. Any other ideas? Thanks in advance.

  • Aironet 1100 Radio disabled at power up

    Just setting up an Aironet 1100. Anytime I reboot (or if power is lost) it comes up with the "radio" disabled. I understand that this may be the default behavior before configuring but shouldn't it remember the settings so it reboots to the last state? I am sure it is not desired to have to reenable the radio on every AP after a power failure. What am I missing?
    Thanks. Bruce
    Model info and software versions below:
    Product/Model Number: AIR-AP1121G-A-K9
    Top Assembly Serial Number: FTX1033V144
    System Software Filename: c1100-k9w7-tar.123-8.JEB1
    System Software Version: 12.3(8)JEB1
    Bootloader Version: 12.3(2)JA4

    Thanks Mike:
    I had seen that info about 12.3(4)---but thought that applied to default behavior and not whether it would explain losing the enabled status at every reboot.
    Should I try to upgrade the bootloader to a newer version (can that be done, where are the files?). Some of the terminology is confusing. I wasn't sure if that applied to my system (12.3(2)JA4) since that talks about 12.3(4)JA2 having the radio disabled by default and no SSID.
    I actually had tried to upload the newest system software (from JEB1) but that failed.
    Does the system software upgrade also update the bootloader version or are they independant?
    thanks for you help

  • Setting up Aironet 1142n as repeater

    I've just recently purchased the Aironet 1142n and am hoping to set it up as a repeater. I've followed the documentation here:
    but am still having problems.
    What I'm trying to achieve is:
    I have an adsl router (TP-link W8960N) at the front of the house but the wireless signal does not reach all the way to the end of the house. I am trying to set up the aironet 1142n to act as a repeater and place it in the middle of the house and hopefully that will extend the wireless signal to the end of the house and remove the dead spots. I would like to do this without having ethernet cables running all over the place and have been trying to configure the aironet 1142n to no avail. Every time I set the aironet 1142n to "repeater" it automatically coverts back to "access point" under role of radio network.
    I guess my main question first of all is, can I set the aironet 1142n as a wireless repeater? And if so, where am I going wrong in my configuration?
    I've just read that "
    Repeater access points running Cisco IOS software cannot associate to parent access points that that do not run Cisco IOS software."
    Does this mean the aironet 1142n set up as a repeater will not work if the original access point (in this case, the TP Link adsl wireless router) isn't a cisco brand?

    Karen: Im not aware about any cisco IOS based device that will help.
    I suggest that you post you question in small business -wireless section. If they know such a product they will help.
    You can also look for TP repeater since your AP is TP already.

  • Aironet 1100 AP (11.b) - am I stuck with WEP?

    Hi all,
    I have several Aironet 1100 series access point. These are the 11.b with WEP encryption. Can I upgrade those to WPA or higher, or am I stuck with what I have?
    Thanks in advance for any information.

    Hi Noel,
    try out this one:
    This is a step by step guide for WPA2. You can not have WPA2 since the lack of a G-Radio interface. But WPA is possible.
    Just change these few things:
    Step 2a. Choose TKIP as Cipher
    Step 3c. Tick also CCKM
    I have the same setup running with 1200 APs only b Radios.
    The difference is that WPA uses TKIP for encryption and WPA2 AES.
    WPA2 is the modern implementation, but WPA meets the actual security needs of the most companies.
    I hope that helps.
    Best regards,
    P.S. Please rate helpful posts.

  • Aironet 1100 / 802.3af Power Over Ethernet (POE) Support

    I was under the impression that the Aironet 1100 supports 802.3af POE. I purchased a NetGear FS108P POE switch, however, when I plug in the 1100, it does not receive any power.
    I have seen references in the documentation to a Cisco inline power injector and a Cisco Catalyst switch that can provide POE to the 1100 and maybe they will work, however, will the 1100 only work with those devices?? If so, it would seem that the 1100 really doesn't support the 802.3af standard and that Cisco's implementation of POE is proprietary.
    Any input would be appreciated.

    Hi Michael,
    As you have discovered (unfortunately) is that the 1100 only supports Cisco Pre-standard PoE :( Have a look;
    Single 802.11g radio offering 54 Mbps of capacity
    2.4 GHz integrated diversity dipole antennas
    Available in an autonomous version only
    16 MB of memory with 8 MB of storage
    Operating temperature range of 32 to 104?F (0 to 40?C)
    **Inline power support (Cisco pre-standard)**
    From this doc;
    The good news is that either of the options you listed will work just fine. I would go for the power injector probably just for neatness sake.
    The Cisco Aironet 1100 Series can be powered either locally using the AC-DC power adapter, or over the Ethernet cable when coupled with a device capable of delivering in-line power, such as an in-line power-capable Cisco Catalyst? switch, Catalyst in-line power patch panel, or Cisco Aironet Power Injector.
    The AC-DC power adapter is included with the access point and can also be ordered as a spare part. The Cisco Aironet Power Injector can either be configured to the order or can be ordered separately.
    You can use either;
    AIR-PWR-A= Cisco Aironet Power Supply-Input 110-240VAC, Output 48VDC, 380 mA-for 1100 and 1200 Series
    AIR-PWRINJ3= Cisco Aironet Power Injector for the 1100 and 1200 Series Access Points
    From this doc;
    Hope this helps! And good luck!

  • Aironet 1100 Errors

    I have two Aironet 1100s (channel 1 & channel 11) in a classroom. I've noticed a lot of Header CRC and CRC errors in the radio statistics. What causes these errors?

    CRC errors and PLCP errors can occur due to Radio Frequency interference. The more radios a cell has (APs, Bridges or Clients), the more are the chances of the occurrence of these errors. A cell means a single channel (for example, channel 1) or a channel that overlaps the channel. Radio interfaces are half duplex. For more information on this read

  • Configuring Cisco Aironet 1100 Access Point. Please help!

    Hi all,
    I have dozens of Cisco Aironet 1100 access points, each is managing its own wi-fi with DHCP.
    I had to disable dhcp on them because they are on a wired subnet where I am using the static IPs and don't want my wired clients to get DHCP addresses, nor someone to be able to plug the wire into own laptop and get on the network.
    It's been working fine with one exception - I need to be able to ping my access points from the central site, and I can't.
    What IOS command would enable ICMP echo on my access points in this case?
    Please help!

  • Event log errors after upgrading Aironet 1100

    We have upgraded an Aironet 1100 to 12.3(8)JA. We used TFTP for the upgrade and everything seems to be working properly.
    However, the event log shows the following message every four seconds: "System running-config write error; configuration failed" This has Error as the severity.
    Every thirty minutes another, Critical error is logged "Memory allocation of 900000 bytes failed from 0x22DC78, alignment 0"
    I've searched the site and can't seem to locate applicable information on these errors and what they mean. Can someone help?

    Oddly enough, this is the most stable AP we have! A PDA can connect to it and stay connnected, whereas our other 1100s (which have not been upgraded and generate the same error messages but only once or twice a day)will permit a device to connect then boot it off after a few seconds to several minutes. We thought the upgrade would make the AP connections more stable but were surprised to see the error messages being generated so rapidly.

  • Bluetooth radio disables itself

    My wife has a BlackBerry Pearl and since she is not on an enterprise server, I have it set up to connect to our home PC using Bluetooth.  It works beautifully and will perform a wireless sync of her calendar and contacts whenever she is within range of the PC.  The only problem is that the BT radio on the phone has a mind of its own and turns itself off after some time.  I haven't determined if there is any sort of cue for it to turn itself off or not.  I just know that every couple of days, I grab her phone to make sure that she has been syncronizing regularly (of course she doesn't) and the BT radio is off.  I then enable the radio, at which point the PC prompts for a connection and the sync routine then launches.
    I've seen other threads in this forum that talk about the BT radio disabling after a period of inactivity when connected to a headset.  I would assume that this is the same problem.  Any answers???

  • Aironet 1100 Default Username and Password not working

    I have a Cisco Aironet 1100 series access point (AP1120B) that after resetting to factory defaults the default username and password (Cisco and Cisco) aren't working in the web GUI.  I am able to telnet to the AP's IP and log in with Cisco and Cisco but don't know the ENABLE password. I have tried Cisco and cisco and everything else i could think of with no luck.  any help would be appreciated. 
    I also have a Cisco Aironet AP1242AG that is doing the same thing.

    Hi Rich,
    I assume that you are using the mode button to reset the configurations on these units -- this procedure *should* reset all credentials to Cisco.
    If this is still not working, you can try the following:
    1) Connect console port and power-cycle unit
    2) When IOS starts loading, hit ESC key twice to get to the boot-loader prompt
    3) At the boot-loader prompt show a directory of the flash filesystem (dir  flash:)
    4) Delete or rename the files "config.txt" and "env_vars", then boot  the  system ("delete flash:/config.txt" "delete flash:/env_vars")

  • No IP address on Aironet 1100 AP

    We have 5 Aironet 1100 series APs deployed in one of our buildings. A few days ago, 3 of them showed down in our monitoring. The next day the other 2 showed down. When I go to the switches that they are attached to and do a show cdp neighbor detail, I see all the access points but NO IP address. Also, when I went to to site, I can connect to the APs via wireless and be on the network just fine. We have static IP addresses assigned to them. However, they are not pingable and do not show up in the ARP table of the switch.
    They have been running a couple of years without changes.
    Any ideas?

    Probably a dumb question but have you rebooted the AP's? Also, are they drawing power from a powered switch or do they have their own mains power bricks attached?

  • LAP 1142N "Radio disabled due to PoE" after upgrade to 7.6.120

    Recently, we upgraded our 5508 wireless controllers from to
    One AP (AIR-LAP1142N-E-K9) doesn't work now.
    Both radios are stuck in state 'reset':
    AP#sh int dot11Radio 0 | inc Dot11Radio0
    Dot11Radio0 is reset, line protocol is down
    It seems to be a PoE issue:
    AP#sh controllers dot11Radio 0
    Radio disabled due to PoE
    This 1142N is connected to a HP switch (model 3800 with 802.3af/802.3at support). It did work on this switch several months before this upgrade and it works if connected to Cisco switch (Cat 6513).
    We didn't upgrade the switch firmware or change its configuration.
    The PoE status from the switch CLI:
      PoE    | Power  Power    Alloc Alloc Actual Config   Detection   Power Pre-std
      Port   | Enable Priority By    Power Power  Type     Status      Class Detect
      ------ + ------ -------- ----- ----- ------ -------- ----------- ----- ------
      21     | Yes    low      lldp  33 W  7.8 W           Delivering  3     off
    Other APs (80 3602 connected to HP8212zl switches) do work without any problem.
    Any idea how to solve this?

    After updating to 7.6.120 we've noticed that some of our AP's wouldn't  come up. After looking in the switch's logs I found this
    chassis: Ports  PoE usage has exceeded threshold of 80%.
    The power drawn is 117w (show power-over-ethernet). 
    When I use the following command: show power-over-ethernet brief I get this:
      PoE   | Power  Power    Alloc Alloc Actual Configured  Detection   Power Pre-std
      Port  | Enable Priority By    Power Power  Type        Status      Class Detect
      ----- + ------ -------- ----- ----- ------ ----------- ----------- ----- ------

      10    | Yes    low      usage 17 W  0.0 W              Disabled    3     off
    Port 10 is where the missing AP is on. 
    How is it possible that after the update to 7.6.120 the AP won't work anymore?

  • 3600 AP %CDP_PD-2-POWER_LOW: All radios disabled

    Hi All,
    I am facing issue with some 3600 APs. These aps are not joining WLC. We have total 137 APs. out of which 97 are registered but rest of them are not getting registered and I am keep getting message on AP console %CDP_PD-2-POWER_LOW: All radios disabled.
    While troubleshooting I noticed that Controller can ping these IPs but with drops. So I thought it is a cable issue but when I connect AP directly to switch ports still I get ping drop from controllers IP. When I look at switch port power it shows 13.0 for all non registered APs where as working one is showing 15.4. I have checked there is no network issue. WLC can ping other APs very well being in same subnet only APs which are not getting registered are not pingable 100% there are drops while pinging APs.
    All APs are in same subnet and WLC MGMT interface is in different subnet. AP joins WLC via option 43.
    I am attaching logs from AP console. I am runing 7.5.102
    Can any body help me on this.

  • Linux clients not associating with Aironet 1100

    Does anyone know if there is an issue with a Linux client associating with an Aironet 1100 using WEP? Windows clients are connecting fine, and the Linux client connects to Linksys branded APs with WEP no problem.
    Aironet config:
    IOS 12.3(2)
    16 AP on same SSID, different cells
    128-bit WEP
    Linux client:
    Dlink Airplus DWL-G630
    Kernel: Slackware
    Commands used to associate
    ifconfig ath0 up
    iwconfig ath0 ath0 mode managed key restricted [2] {key}
    dhcpcd ath0
    After bringing up the ath0 interface, and running the iwconfig, you can see the iwconfig settings are sticking, but it seems to be jumping around APs when you watch the MAC of the AP. It goes from a valid MAC address to FF:FF:FF:FF:FF:FF and then to another valid address, and back again. This does not happen on the Linksys AP.
    Any ideas?

    Try entering the key (on the Linux box) as hex.
    Most of the Windows client software lets you enter the key in ASCII ... some client software requires that you put in the hex translation.
    You can check the logs on the 1100 to see what the failure message is ,,, but I'd bet it'll be something along the lines of "Invalid Key"
    Good Luck

  • Setting aironet 1100 to factory default

    I am trying to reset an aironet 1100 back to factory default. The only button on the bottom of the unit that I can see is one that says mode on it. Is their somewhere else where the factory default can be reset at. Thanks

    This should work for your situation:
    Reset the AP—Cisco IOS Software
    Complete the steps in this section in order to reset Cisco IOS Software-based APs.
    Note: Cisco IOS Software-based APs have a default configuration that includes a username and password combination. Both the username and password are "Cisco", which is case-sensitive. After you reset to factory defaults, be prepared to give "Cisco" as both the username and password when you are prompted by either the GUI or the command-line interface (CLI).
    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.
    If neither the GUI nor the CLI is available with sufficient privileges, complete these instructions in order to use the Mode button:
    Disconnect power from the AP.
    Disconnect the power jack for external power or the Ethernet cable for inline power.
    Press and hold the MODE button while you reconnect power to the AP.
    Hold the MODE button until the Status LED turns amber, and then release the button.
    The Status LED turns amber in approximately 1 to 2 seconds.
    After the AP reboots, reconfigure the AP and use the web browser interface, the Telnet interface, or Cisco IOS Software commands.
    Note: The AP is configured with the factory default values that include:
    The IP address, which is set to receive an IP address with DHCP
    The default username and password, "Cisco"
