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

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"?
ThanksI 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 / 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.
Thanks,
MichaelHi 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;
http://www.cisco.com/en/US/products/hw/wireless/ps4570/prod_brochure0900aecd8035a015.html
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.
POWERING OPTIONS
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;
http://www.cisco.com/en/US/products/hw/wireless/ps4570/products_data_sheet0900aecd8045690f.html
Hope this helps! And good luck!

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?
Thanks
CarlProbably 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 7.4.110.0 to 7.6.120.0.
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
----- + ------ -------- ----- ----- ------ ----------- ----------- ----- ------
1 | Yes low lldp 17 W 7.0 W Delivering 3 off
2 | Yes low lldp 17 W 7.0 W Delivering 3 off
3 | Yes low lldp 17 W 6.8 W Delivering 3 off
4 | Yes low lldp 17 W 7.1 W Delivering 3 off
5 | Yes low lldp 17 W 7.0 W Delivering 3 off
6 | Yes low lldp 17 W 6.9 W Delivering 3 off
7 | Yes low lldp 17 W 6.8 W Delivering 3 off
8 | Yes low lldp 17 W 6.7 W Delivering 3 off
9 | Yes low lldp 17 W 6.9 W Delivering 3 off
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.New-ASW01# sh power in

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:
http://www.cisco.com/en/US/tech/tk722/tk809/technologies_configuration_example09186a008054339e.shtml#config_ap
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,
Frank

Disable all power button functions in Windows 7
I'm configuring some Windows 7 clients to be very locked down and only run a specific application.
They auto logon correctly and start the application, but I have been unable to completely disable the power button in the start menu so that the users cannot turn the machines off in any way. I have set disable logoff and removed access to shutdown, restart,
sleep and hibernate through group policy, but the button still defaults to logoff, with all the additional options in the arrow menu unavailable.
My only other thought was to try a custom GUI instead of explorer.exe, but would much rather do it through group policy or registry if possible.I ran into this problem with Windows 7 at a radio station. We needed to prevent our on air talent from performing any of the start menu power actions at all. We have a Reboot Script should it need to be rebooted, and we can access the system
as administrator by holding SHift key during boot up.
We basically needed windows to be set up like a KIOSK, stripping and disabling - Shutdown, Switch user, Sleep, Restart, Logoff and Lock. here is what I have found to work. I found this blog....

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

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
Hello,
This should work for your situation:
Reset the APCisco 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"
Here is the link to the actual doc:

Aironet 1100 won't show IP Addr. w/ IPSU
I am trying to set up a Aironet 1100. I enter the mac addr. into the IPSU and get a error - device does not answer. I've reset the device, ng. Tried 2 different computers, ng. I cannot get to the config. page. Any ideas?
Plan B: Get yourself a copy of tftpd from here:
http://tftpd32.jounin.net/
A very lightweight TFTP & DHCP server (amongst other things). Install on a PC and connect to the new AP with a cross lead (or in such a way that the PC and AP are isolated from the main LAN). Start TFTPD and configure a DHCP scope, power on the AP and watch the TFTPD log screen. Connect to the AP with a browser and give it a static address on the main LAN.
Plan C: Connect a console cable to the AP and reboot it, watch the boot process carefully and you'll see the IP address it leases. -
Aironet 1100 dropping connection

Here is the some steps which will help you to resolve the issue.
Set the data rates to 'Best range'.
Recommended to set the APs to non-overlapping channels.
Suggested to reduce the size of the cell by changing the power settings.

Hi !
I'm doing a project on trilateration in which is required to list the BSSID and power levels from the APs, since we have alot of Cisco Aironet 1100 deploye here, could this be a choice ?
My first try is to get these values using snmp, but so far had no luck finding the right MIB. I don't think the console might help me, will it ?
I know I'm assuming alot, that the Aironet enables for a 'iwlist' dump, and that these values can be retrieved through snmp. But seems something reasonable for them to have, even if I haven't found it.
Any help would be much apreciated.
Thanks !
Pedro G.Hello Pedro,
As per your query i can suggest you the following solution-
Multiple BSSID Beacon Settings
Multiple BSSID Beacon
Select the Set SSID as Guest Mode check box if you want to include the SSID in beacons. Refer to Configuring Multiple BSSIDs for further procedural information.
To increase the battery life for power-save clients that use this SSID, select the Set Data Beacon Rate (DTIM) check box and enter a beacon rate for the SSID. The beacon rate determines how often the access point sends a beacon containing a Delivery Traffic Indicator Message (DTIM).
When client devices receive a beacon that contains a DTIM, they normally wake up to check for pending packets. Longer intervals between DTIMs let clients sleep longer and preserve power. Conversely, shorter DTIM periods reduce the delay in receiving packets but use more battery power because clients wake up more often.
Hope this will help you.
