Cisco Wireless :: Webinterface Does Not Work After Downgrade Of AIR-LAP1142N-E-K9
Jan 24, 2013
I have downgraded one of our AP1142N-E K9 to Autonomous mode with this image: c1140-k9w7-tar.152-2.JB.tar I have uses cisco's instructions.
After successfull installation, I can open the Webinterface, but it shows almost no information. Only Device Type end serialnumber, but nothing more. Also it is not possible to save any configuration.
Alternatively I have installed:
c1140-k9w7-tar.124-21a.JA1.tar
Same problem. I have tried it with a LAP1252N later. Same problem.

I would like to downgrade Cisco Aironet 1142N to autonomous. But I would like to know is there any way to download the LWAPP IOS before upload the Autonomous IOS ? because I want to upgrade the 1142N from autonomous to LWAPP when I buy a LAN Controller.
Is that possible to use that backedup LWAPP IOS when I want to upgrade the Cisco Aironet 1142N autonomous to LWAPP?

We have an AIR-LAP1142N-E-K9 deployed in a H-REAP setup.This AP already got the configuration from the WLC when it was deployed at a remote site.Now we moved it to another site, but it doesn't appear in the WCS and i don't see any CAPWAP debug messages on the WLC.The routing work fine between the AP and the WLC, the AP also gets an IP address from DHCP and also received Option 43 information.
Now my guess was that the AP doesn't associate with the WLC because it has the old config file and it runs in local mode(without trying to connect to the WLC).We want to reset to factory defaults because we want to delete the configuration and force the AP to get a new config from the WCS.I don't know the enable password so i had to use other methods for reseting to factory defaults.
I tried to use the information from here:[URL]I used the "MODE button":I get the following message from the console:
"button pressed for 5 seconds
process_config_recovery: set IP address and config to default 10.0.0.1"

we are having trouble logging into the webinterface of our DCNM installation.
(Cisco Prime DCNM 6.1(2), Windows 2008 R2 SP1 64 bit version, US)
Everything seems to be working fine so far, except the login to the webinterface.
When calling https://<SERVER_IP> (we're using 443 and 8443 in our setup), the login page appears. Entering the credentials results in the message "Authentication Failed. Please try again.". We tried that from a remote machine and the server itself and are using local authentication (not RADIUS or LDAP, ...).
On the other hand, when running the DCNM LAN Client (using the same credentials not working for the webinterface), there is a link (see image below: "here") pointing to the webinterface.

I have a WLC with, let´s say, 30-40 AIR-LAP1142N-E-K9. Since last November the following issue happened 3 times. One of the APs (it´s always the same unit) remains online but both WiFi interfaces appear down. I´m unable to put it back UP like if they were disabled. Then i have to reboot the AP and it starts working again.
What could be happening? Should i open an RMA for this unit?

I've just bought an AIR-WLC2106-K9 and 3 x AIR-LAP1142N-E-K9 and I'm having a problem getting the AP's configured.
Firstly, the controller did not discover the device when it was on the same sub net, I had to plug it straight in which is no good for wireless-n due to the 100Mbps port speed on the controller. Secondly, when I am editing the AP through the controller webpage, none of the details are saved after applying changes (static IP etc).
I followed the Cisco quick start guide for the controller to get the basic config, radius server details etc in. It is running software version: 4.2.61.0

I'm new to wireless and I have 7 Cisco 1142N (AIR-LAP1142N-A-K9) APs. But The thing is I have to buy a WLAN controller for these APs. I checked on internet and I found the 2500 series Controllers are compatible with Cisco 1142N (AIR-LAP1142N-A-K9) APs. But I would like to know How can I find the exact supporting version of controller for Cisco Access points?

We have a problem with AIR-LAP1142N access points.
AIR-LAP1142N-E-K9
Version 12.4(21a)JA
LAP's are not assotiated with controller yet. They get the ip address via dhcp, they are reachable by icmp.When I try to telnet, I get Password required, but none set? Is there any chance to get access to them without using serial port?

I have a wireless deployment using a 5508 controller and 90+ LAP1142N lightweight access points.Everything is going relatively well, except I have about 3 that do not keep their config (hostname and AP group) past a reboot of the access point.When they do come up after a reboot, they go back to the default hostname of the mac address and are placed in the default-group AP group.

I'm in the process of trying to get a used LAP1142N access point connected to my already established WLAN. We currently have 7 active LAP1142N, our controller is a AIR-WLC2112-K9, and I am only trying to add one additional access point. I say this access point is used because we purchased it used, given it's not out of the box and hasn't ever been active in my environment. So far what I've tried is initially connecting the access point on to my network (powered over Ethernet) and consoled in from my desktop. With this, I was able to see the previous configuration so I ran a write erase/ reload. The AP shows a solid green light, but doesn't receive any configuration from the controller even when plugged directly in to the controller (on ports 7 and 8). I'm new to wireless, but familiar with Cisco CLI and web interfaces. I can't necessarily tell if this AP is set to autonomous as opposed to lightweight, but that could be the problem. Otherwise I'm lost. I've attached text files with the boot from CLI and show run from CLI.Let me know any additional information you may need. End note, I'm recieving DHCP (you can tell from boot), but it's not the same subnet as my controller or other active access points.

We have a set up which includes several air-lap1134n-e-k9 access points. We're having problems with a specific laptop connecting to the WLAN which is accessible via the AP. We can see numerous different SSIDs available and when we connect to either of the two we have set up it says it is unable to connect. One of the connections, let's call it Internet, has Layer 3 security set up. The other connection, Web, has Layer 2 security set up. The laptop can connect to neither. It can, however, connect to other wifi in the vacinity including a wifi hotspot we set up on an Android phone.
The laptop has an Intel Centrino Wireless-N 1030 network adapter with current drivers. The WLAN's we've set up, Internet and Web, are both enabled for 802.11n.

Some time ago I updated a WLC, model 2504, from version 7.3 to 7.4.100.0. I also update the FUS (Field Upgrade Software) to the latest release, 1.8.0.0. Now I need to downgrade the WLC back to 7.3 version.
My doubt is: Can I just take the normal processes and downgrade the WLC back to 7.3, even with the FUS in version 1.8.0.0?

1) AP was originally running a standalone image. I booted it into a so-called ROMMON or AP mode (ESC is the right key to make it boot into this mode).
I found a recovery image in its flash - c1140-rcvk9w8-mx. I made the AP boot from it by using "set" command and I see that it start booting using this recovery image. Here goes the question. Do all AP settings matter ? E.g. when I run "set" command from AP I see the following:
ap: set
?=
DEFAULT_ROUTER=10.0.0.1
Default_router=10.9.99.1
ENABLE_BREAK=yes

I have a LAP1142N that is connected to a 3560 nonPoE switch (using compatible power injector) that will not associate to the controller I have set-up. The wireless is existing and I have about 11 other APs connected to the controller with no issues. The AP will pull an IP address from DHCP running on the primary controller. The AP pulls a new IP address in roughly a minute. I set the pool to be 3 IP addresses and set a contant ping to each, there is about 1 request time out before the next IP address starts pinging. I went to the controller and pulled the following message error from the log.
*Feb 13 14:24:58.614: %LWAPP-3-HDR_ENCAP_ERR: spam_lrad.c:4216 Unable to encapsulate LWAPP header for discovery response; AP (APs MAC address)

I have tried a different cable, connecting to a PoE switch, different controller, larger DHCP range, hosting DHCP on the distribution switch, I am awaiting console access to the AP since this is remote work. The controller is running Software Version 5.1.151.0. Thoughts?

I am currently experiencing an issue with a WLC that I am trying to connect 3 new Access Points to of the type AIR-LAP1142N-E-K9 running Cisco IOS Software, C1140 Software (C1140-RCVK9W8-M), Version 15.2(2)JA
I had the controller on firmware 7.0.220.0 and just upgraded to 7.3.101.0 in the hopes to solve my issue. The already connect APs running 12.4 was upgraded without any issues (apart from one - I'll get to that one) and it is now running as before. But the issue with the 3 new APs still persists. I have supplied a screenshot of the AP Join page.
Another issue that arose from the said upgrade was that a previously shutdown AP (of the same type and software version as the ones that upgraded perfectly) got turned on after the WLC firmware upgrade and is now not able to join the controller.

I have two AP models in my network. LAP1142N-A-K9 and LAP1142N-N-K9. The LAP1142N-A works fine with both radios (a/n and b/g/n), but the LAP1142N-N is getting a regulatory domain not supported problem with the 802.11a/n radio, which is keeping it in the down state. I'm in Canada, and my country code on my 5508 WLCs are set to CA. My WLCs are running firmware version 6.0. I read over some specs and the difference between the two APs is FCC cfg vs Non-FCC cfg... Not 100% sure what that means.

Working on a project consolidating all controllers to a single 8500 controller with a standby. Moved an AP over to test the process and everything worked fine. Took a little longer than I thought it would, but given the design with new flexconnect abilities, the creation of AP groups well you know.
I get the AP over and one of my ssids doesnt work because the key is different, so gotta move the AP back over to resolve production issues.
when downgrading from 7.4 to 7.0?

I have 19 locations, each with 1 or more LAP1142N AP's in FlexConnect mode, AP's are primed using CAPWAP to my 5508 WLC at the datacenter. The AP's join the WLC without issue every time. I have two WLAN's, one guest and one staff, the guest network is open and obtains DHCP from a WatchGuard XTM33 firewall at each of the remote locations. The staff side is WPA2/RADIUS and DHCP is assigned from the WLC. Each AP is assigned a static IP that is not in the DHCP scope. For example: DHCP scope on the branch firewall is 192.168.1.10-250 the AP will be assigned static IP of 192.168.1.1.. The AP's are connected to a HP procurve switch that has a untagged VLAN, the firewall is using the native vlan 1 and so is the AP.
I have been running this network for over a year and it has not had a single issue until the last two weeks. Nothing on the network has changed or has been upgraded.The issue I am seeing is that clients are no longer able to connect to the AP and do not get DHCP assigned to them. I am able to get it working, if I remove the static IP from the AP, the AP will reboot, join the controller, then begin working, users can connect and DHCP is assigned from the firewall as it should. However, If the AP then reboots, the AP will join back to the controller but no clients can connect nor do they get a DHCP address. So, I then reassign a static IP to the AP again and it reboots, connects to the controller and clients then can connect and get DHCP.i've found several posts on this topic, in fact the patch of unassigning or reassigning static IP is one that I found. I am also waiting on my SmartNet to start up and will be contacting Cisco support as well.

I just pulled the AP out of the box and haven't received support contracts yet. I connected the AP to the LAN and added it to my 4402 controller (version 5.2.178.0) with no problems. Once I set it the mode to H-REAP and it rebooted, it went loopy. Actually, it boots up, shows a bunch of debug info, then reboots. The console output is below. I've tried reimaging (image c1140-rcvk9w8-tar.124-21a.JA2.tar) but still have the same problem. I checked and although the controller software is old, the AP is supported.

We have a strange problem. We have a WCS v.7.0.172 that controls our two WLC v.7.0.116 and we have also two "Anchor Controller" WLC
v.7.0.116 for Guest Access.
We use the LAP1142N and every AP has two SSID's. One for internal data traffic and the other one for the guests.
Now the problem is, that even if we have internal and external user on the same AP, the guest users gets disconnected after a few time. Sometimes after 20 minutes, sometimes after 90 minutes...but the user is still working. It's really irregular.

I have trouble accessing the internet from my laptop after installing Ciso AIR-LAP1142N-A-K9 AP.The AP are connetected to my router (which has a DHCP enabled) via a switch and each has a Fix IP address with network mask, gateway and DNS already configured. When I triy to connect to the access point, only the IP address and network mask are automatically assigned to the my laptop. and I have to manually input the gatway and DNS to be able to navigate the internet. I would like to know which configuration will allow any node that tries to connect the internet via the access point to be automatically configured to access the internet after authentication.

I have to prepare an 3600 Capwap AP for autonomous functionality!
The following image was downloaded: ap3g2-k9w7-tar.152-2.JA
The release notes say: Site-Survey Only Mode for 3600, 3500, and 1550 Access Points You can install Cisco IOS Release 15.2(2)JA on Cisco Aironet 3600 and 3500 Series access points and on 1550 series outdoor access points to perform site surveys. This release runs on these access points with limited functionality. You can manually adjust these settings on the site-survey access points:
• Channel on each radio
• Transmit power on each radio
• Enable and disable the radios
• Manually set basic and supported transmit rates
• Enable advertised cell power in beacons to client to enable DTPC for doing active surveys
• Enable and disable SSID broadcast in beacons
• Enable open authentication
My Question is: Where can i find a instruction for downgrading an AIR-CAP3602i to Autonomous 3600 AP? Is it complicate to get the AP running, or what do i need for "downgrading"?
