Cisco Wireless :: 1142 Converted To LAP And VLANs

Jan 22, 2012

I just converted AP 1142 to LAP using the image "c1140-rcvk9w8-tar.124-21a.JA2.tar".
The WLC is a 5500 with 2 NIC : one on 192.168.0/24, one on a specific vlan 10.20/16
The main management interface is on 192.168/24 but we defined as management the interface on the 10.20/16 network.
For the access points, we use ports on a native VLAN on 10.20/16 with other available VLANS which are used for the wlan networks
We have 1152 APs which work fine on this config but that needed to be registered on the 192.168/24 network, then we moved them in their VLAN 10/20/16 and they work fine.
We also have 1142 APs which have been upgraded to LAP. These AP do not work with our architecture. They register correctly on the 192.168/24 network, but do not give access to the wlan VLANs. If they are moved in the 10.20/16 network, they don't register to the WLC (message : Timed out while waiting for ECHO repsonse from the AP). The AP do not get an IP.
is there a restriction with VALNs on these AP ? or is something false ?

Cisco WAN :: UC520 / FQDN Converted To IP Address?

Jul 11, 2011

I am trying to setup time service on two devices.  Once is a UC520, the second an 1840 router.  I would like to use the FQDN of the time server which is  This is the recommended procedure as per due to changes of IP addresses of time servers.
On the UC520 this is not a problem.  I type in "ntp server" and this is how the command stays in the config.  On the 1800 the FQDN is resolved and inserted into the config as an IP address.  This works for now but kinda defeats the purpose of using a FQDN.
How can I keep the 1800 from converting to IP?

I have an 1142 AP that I am unable to set back to factory defaults.Here is what I have done so far:

- boot AP while holding down the mode button

- ap: delete flash:private-multiple-fs

- yes

- ap: boot

- when the AP boots fully I try and enter any lwap ap commands and get "ERROR!!! Command is disabled"

- the AP name and password were reset to defaults but I am unable to get the IP address cleared.
I've also tried "clear lwapp private-config" and get an error saying the command is disabled.

Cisco Wireless :: 1142 AP Antenna Configuration?

Aug 13, 2012

When we take a look at the internal antennas on the 1142 AP, we notice the 5ghz pointed all the same way, but for the 2.4ghz we can see each offset by 45/120 degrees. It was my understanding that all antennas are omnidirectionals on the 1142, why are those 2.4ghz antennas not all pointed the same way? onfiguration advantage and that each antenna is indeed omnicadirectional? Example, if I shut just one antenna off, do I lose a sector (120degree)?

Cisco Wireless :: Setting Up Additional 1142 AP?

Jul 27, 2011

I recently purchased another 1142 AP to expand out our current wireless infrastructure, my question is, what exactly needs to be done for this to work so that users can roam freely and auto-connect to the closet AP with the best connection without getting disconnected?
I have set all the settings the exact same on the new AP to match the existing AP. (How to save the configs into a file would be great, I am not sure how to do that)... But anyhow, before I launch it, I would like to be sure I am correct so I do not bring down the existing network. Of course, the only difference between the 2 are the IP addresses. AP1 is and AP2 is

Cisco Wireless :: 1142 LAP In Operational Status (Down)?

Nov 1, 2012

The last three new APs I have received from our supplier (official Cisco 1142 LAPs) have all successfully connected to our 4400 series WLCs but are all reporting as being in an Operational Status of 'Down' ie their A/B/G/N radios are not broadcasting even though the APs are all in an enabled state. Furthermore, there is no steady green light showing on the APs - there is no light showing whatsoever (although they were displaying the familiar red-orange-green lights while they were pulling down the IOS images from the WLCs).
The only strange thing I have noticed is that in the AP config screen, the ‘Mini IOS version’ is shown as being v7.3.x. The other – working APs – we have of the 1142 series show v3.x. I know that controller code v7.2 and above only work with the newer 5500 and 7500 series WLCs. Could this be the issue and have any of you seen this issue previously? I am running WLC code v7.0.230.0.

Cisco Wireless :: Aironet 1142 Keeps Rebooting

Jul 27, 2011

About every 20 minutes 12 of 300 APs keep rebooting.  I have tried moving them to different controllers.  I have tried downgrading the code and then upgrading the code.  I have tried replacing the AP.  I have tried swamping out cables.  They are all connected to a 3750 stack but plugged into different switches in the stack.  Here is the result that I could capture when I saw it disconnect from the controller.  This is the output from the AP:
DTLS-5-SEND_ALERT: Send FATAL : Close notify Alert to

Cisco Wireless :: 1142 In Repeater Mode?

Jun 2, 2012

I am a bit confused of the repeater functionality in the mentione AP, my concerns are:
1- Will each radio be dedicated to one function (for example 2.4 GHz for user access and 5.0 GHz for repeater functionality)?

2- Will the internet speed for users be affected when using the access point in repeater mode (no ethernet)?

3- Can an Autonomous AP function as a repeater?

4- Is there any license required?

5- What is the signal overlap requirements between the two Wired and non Wired AP?

6- Can the non wired AP be work as a repeater for another non wired AP (similar to cascading)?

Cisco Wireless :: 1142 Azimuth And Elevation In NCS

Mar 4, 2012

I have recently been adding a number of installed APs to heatmaps in NCS and am very confused as to the correct Azimuth and Elevation settings.
In particular - if the AP is mounted on a wall rather than a ceiling what should the settings be ( and does it matter - perhaps - as NCS is now dynamic by default rather than the old WCS being predictive perhaps it does ).

Any guide for this covering the following common installation locations.
All referenced when looking at the map view in NCS, front of AP is the side with the Cisco logo and the status LED:-
1. AP ceiling mounted ( Backplate pointing out of map towards your eyes - front of AP pointing down to floor )

2. AP wall mounted ( front of AP pointing upwards towards the top bezel of the screen )

3. AP wall mounted ( front of AP pointing right towards the right bezel of the screen )

4. AP wall mounted ( front of AP pointing down towards bottom bezel of screen )

5. AP wall mounted ( front of AP pointing left towards left bezel of screen )

Cisco Wireless :: 1142 AP PoE Building Lab For CCNA

Apr 11, 2013

After some searching I see many people using power injectors or switches that supploy PoE.  I am building a lab for the CCNA Wireless and currently have an old Cisco 3550 PoE switch and a 2106 Controller that I got at a steal of a price.  My question is, The 1142 can use the 15.4 Inline Power from the 3550 even though it is not the 802.11af standard correct?  If it doesn't then I will need to order a power brick.

Cisco Wireless :: IPad Not Connecting To AP 1142?

Jan 18, 2012

I have an ipad that is not able to connect to a 1142 Autonomous AP. This AP was originally a light weight AP and then downgraded to autonomous.A strange thing i see is that the AP shows me only two radios. 802.11 N(2.4 GHZ) and 802.11 N(5 GHZ). I suspected the AP not to support the b/g networks. i then downloaded the most recent software but i still cannot get it to connect and on the AP's GUI i only see the above two mentionned radios. i tried to connect to two SSID's. one using WPA2 and another with open authentication and no security.but this does not work. Is it possible that some 1142 do not support b/g networks?

Cisco Wireless :: 1142 - LAP Not Retaining Configuration

Aug 27, 2012

I have some 1142-lap that i have to deploy in my office.
I have successfully deployed 5 out of 8 LAPs . Actually the LAPs was not discovering the controller automatically.
So i had to configure the Controller ip adress through the console in tha AP using the CAPWAP command. Then the AP promptly associates with the controller. Later on i configure the AP name - Primary , Secondary , Tertiary Controllers and everything else and saved it on the controller. This worked out well for the 5 LAPs that i had.
But started facing a peculiar problem with the rest three
As soon as i disconnect the AP from my desk and have it mounted on the celing , to my surprise if find that the LAP doesnt retain its configuration and also doesnt associate with the Controller.
Cant imagine what could be the issue.
I have been told that one CANT wite/save any configuration manually on tha LAP using the console, except by associating it with the controller. Is it a fault with the AP ( as the other APs are working absolutely fine)

Cisco Wireless :: 1142 - Wi-Fi Speeds Fluctuating Rapidly

Nov 28, 2012

We have approximately 150 1142 LWAPP's deployed in our facility. Recently we started getting complaints about speed issues (90% are using G 10% N). Upon investigating we found that the speeds are fluctuating rapidly. Everything from 54Mbps down to 1Mbps and back up again. I've confirmed that this will happen while standing next to an AP (and confirming connectivity to it), however I cannot find anything wrong or anything that has changed with our configuration. We are a large facility and it is happening all over the campus, so I'm fairly certain it isn't any type of 'normal' interference.
