I have an 1142 CAPWAP AP running IOS 12.4(25e)JA$ on a 2504 controller running 7.2.103 that's frequently reloading. NCS is reporting the reason for the reload as 'AP Crashed Due To Software Failure'. Other 1142 APs on the same controller aren't experiencing any problems. The AP is in H-REAP mode with local switching but central auth.
View 5 RepliesI am setting up office extend with 1142 APs on a 5508 controller. All seems ok and I see my SSIDs on the remote AP. However when I try to connect I don't get a dhcp address and the connection fails. When I look at logs and some debugs I see dtls keepalive failures and the AP is actually disconnecting and re-associating with the controller.

I've just been on the phone with tech support and it appears that the latest firmware that Cisco Connect is stating that one should install is faulty and is bricking routers.
I've tried resetting it, holding the reset button while powering up for over 5 minutes with no change.
All the router does now is the power light is blinking but no access to the router is possible at all.
My cisco ios 2960S is crashed and the ios is gone The issue is i am connecting my pc to management port and i give switch:

But i can not copy tftp to flash,according that i have L3 port (management) why should i use xmodem?
seeing very strange behaviour of router router is connected to switch to provide analog when swich configured as trunk the router crash and reboot but when change to access its stable

About 5 days ago the computer crashed. I was able to reload Windows XP and load all the drivers and hardware. The only problem is, now the WLAN is saying that it is disabled and I am unable to enable it. The stupid thing about this is, when the computer crashed, the next day i was able to get on. The WLAN was working just fine and so I decided to go ahead and load windows anyways because it has been having issues. Every since I did that, the WLAN has been disabled.

The device is running OSPF (it is in an NSSA). I have several other devices configured almost the same running the same IOS in my network and they are working fine.This does make the third out-of-box 3560C Cisco that has failed on me within a few days.
I have Cisco AP 1142 standalone and I want this one to operate with WLC.
I have searched in Google, they said I need to upgrade AP1142.
I don't know how to upgrade it.
i have a problem using my usb to serial cable connection, i can connect to one router on my work, but i can't connect to AP 1142, (i have tested also con AP 1231).i have a laptop running windows 7 64 bits, before i use a win xp 32 bits, and i didn't have problems.i am using putty, and have installed tera term 4.74 but the same.connection details, 9600, 8, 1, N, N.

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 ?
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.
I need to convert some 1142 APs to lightweight mode. They will connect to controllers running 7.3.101.0. I noticed there's two options of Lightweight IOS code available c1140-k9w8-tar.152-2.JA.tar and c1140-rcvk9w8-tar.152-2.JA.tar. Whats the difference between the two versions of code?
View 4 Replies View RelatedWhen 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)?
View 5 Replies View RelatedI 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 192.168.2.2 and AP2 is 192.168.2.3
All computers are using Linksys Wireless-N cards.
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.
that cisco ap 1142 will support WLC2506 or not .

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:

I have removed the ip addresses for security reasons.
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)?
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 )
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.
