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 10.100.40.212:5246
*Jul 28 14:33:19.595: %WIDS-5-DISABLED: IDS Signature is removed and disabled.
*Jul 28 14:33:19.597: %CAPWAP-5-CHANGED: CAPWAP changed state to DISCOVERY
*Jul 28 14:33:19.597: %CAPWAP-5-CHANGED: CAPWAP changed state to DISCOVERY
*Jul 28 14:33:19.655: %LINK-5-CHANGED: Interface Dot11Radio0, changed state to administratively down
[ code].....
I have removed the ip addresses for security reasons.

When I check the AP join statistics I see the following: Reason For Last Unsuccessful Attempt RADIUS authorization is pending for the AP, I don't run a radius server and don't know how to get around this so that the device can join.

I have an Aironet 1142 access point.
Is it possible to direct it to a webfilter hardware firewall for internet access. For example the IP of the firewall with webfiltering capabilties would be 192.168.0.1
We are hoping to provide customer wifi web access but need to filter what they can access.

I have a 1142 that I purchased that needs to be set to factory defaults so that I can configure it. I do an escape at the boot sequence and I get to the
ap:
prompt, the reset instructions that Cisco provides says that I should rename the old config.txt and reboot and that I will then be able to start my reconfig. The problem is that I can't find a config.txt file in the flash space:
Directory of flash:/

3 -rwx 112947 Apr 1 2011 15:17:10 +00:00 event.log

I checked in the directories listed above and still found no config.txt.

I configured the device manually, not even using Express Setup or Express Security setup so... it is possible I missed something.Anyway, here's the problem. Although the SSID is configured as "AP1", this SSID does not appear among available networks on the client laptop.
The connection, configured in Group Policy for the client, should actually happen automatically, based on the SSID, but since the SSID is not being broadcast, that connection is failing as well.
The Aironet does appear among the available networks as "Other Network" and if I click on "connect" I am prompted to enter the SSID -> AP1
Although, unexplicably, an error message displays (Windows cannot connect to the network, or something to that effect), the laptop *does* connect once I close that window. Network access is complete and functional - I can ping other hosts, etc..
I'd post screenshots but not knowing what setting is missing or incorrect, I'd have to print dozens. So here's the sh run output of the AP obtained via telnet (just below). This is a test network so all information is "real" (nothing changed for privacy):
Note: I even changed the hostname to "AP1" (it's still LAB1 below) but that did not resolve the problem (did not think it would).
LAB1#sh runBuilding configuration...

I'm using the Express Security Set-up tab to configure an Aironet 1142 (stand-alone) access point with EAP.
Objective is to make it a RADIUS client and have laptops authenticate through this access point to a Windows 2008 NPS (Network Policy Server) using computer (machine) certificates - EAP-TLS.
When I select "EAP Authentication" under the "SSID Configuration" I was literally floored to see mention of WEP encryption (a security joke) and no possibility to prefer some variant of WPA (well, apparently not with EAP).
WPA2-Enterprise is what I've selected for "Authentication" and "AES" for encryption in Group Policy (so the laptop clients automatically connect to the access point).
WEP? I bought a Aironet 1142 access point for WEP encryption? How can I configure this securely?
These are currently configured settings as displayed under the "SSID Table" heading:
SSID - "MYSSID"
VLAN - none
Encryption - WEP Mandatory !!!

We have a Cisco aironet 1162N connected to a Wireless Controller (LIGHTWEIGHT mode), the device failed and it needs to be replaced.We have a Cisco aironet 1142N in stock available to use.Can we proceed with the change just with disconnect the failed AP (model: 1162N ) and connect the new one (model: 1142N)? Or there is any other task to be done before the change? since the WLC manages the configuration for each AP.

The GUI times out after 60 seconds.
Since the the "exec-timeout" setting has a default of 10 minutes (if I'm not mistaken), I don't think I could change the timeout value with that command.
Under the "Association" tab of the GUI, there is an "Activity Timeout" subtab and settings for 5 device classes, all set at 60 seconds.
I would guess the setting in question can be configured here. Is the client station device class what I'm after?

We have 5 pcs Cisco Aironet 1142 Access Points without controller at the same building. SSID is same for all of them. Our problem is client connected via wireless disconnecting randomly and continues working after a few seconds. IOS versions are same for all of them you can find detailed information about versions and configurations below.

Aironet 1142, two units, using WPA Radius to IAS on Windows 2003. I have a problem with Macs beginning to surface. One laptop, OSX 10.6, ran fine for a couple of weeks. A problem started occurring, while using the network, communication will stop. The Mac still shows connected on the laptop, and it shows associated in the interface on the Airnonet. However, there is no data transfer. I open a terminal and ping, there is no response. After sitting for awhile trying to ping, it will start again and communicate. After letting the laptop sit for awhile, the same things happens. The connection can be disconnected and reconnected on the laptop to restore connectivity. I did a round of things on the Mac to eliminate problems in configuration there. The same thing happens with both Aironets. Today, the when the problem occured, a user with an iPhone experienced the same thing. This was a first for that iPhone. Another Mac laptop, a newer model, did not experience the problem.
As I am writing this, a user with an iPad now just emailed that he is having trouble connecting. We just recently upgraded this customer to Aironets and disconnected a conglomerate of other products. The last one to be disconnected was a low cost Trendnet, that this iPad user was previously connecting to with no problem. The other device he would have been using in a different area was a Mac Airport WAP.
On the Aironets, I have CCX turned off, have set speed settings to default.

I am using an Aironet 1142 standalone AP and want to use Apples Bonjour Service between iOS devices e.g. iPad and Apple TV.I have found here some posts that suggest to disable igmp snopping but this didn't worked for me.All devices are in the same vlan/subnet. Do I need to configure something special?

We have recently aquired a remote location which has a pre-existing flat network (172.16.X.X/16). Before we are able to convert them over to our new IP scheme, they have a need to have wireless connectivity on site. We have 4 1142's which I need to configure for them. I have experience configuring WLC's and autonomous AP's for networks with multiple vlans but have never configured AP's for a flat, single subnet network. I need to configure them for either guest access (internet only) or corporate access to network resources with radius authentication. Do I configure a native vlan as I would for a typical multi vlan network? Do I configure the switch port as an access port as opposed to a trunk beacause of the lack of layer 3? I basically need a sample configuration for this situation.

I have installed/setup a cisco 2504 wireless controller and 3 aironet 1142 access points using the basic config on a windows sbs 2008 domain, the problem is that the clients that are connected to the 2504 aint getting the there ip addr from the AD but from the wireless controller, and there cant reach the clients on wifi from the clients that are connected to lan, is there anyway that i cant change this so that a client on lan can see the client on wlan and vice versa.

I wonder if there is a way to rename an existing SSID on aironet 1142 without destroying/recreating. I tried downloading configuration/ changing name/ re-uploading however that didn't have desired effect. There doesn't seem to be a way via web-GUI.

First, my configuration, (then the problem down below):
I have an Aironet 1142 with multiple SSIDs [mapped to V LANs] connected to Gi1/0/2 on a 2960 switch in a user-accessible area. This switch is up linked to another 2960 switch in a wiring closet, and the Microsoft NPS server is connected to the wiring closet 2960.
Aironet -- 2960 [user area] --- 2960 [closet] -- NPS RADIUS
I have the user-area 2960 configured as an authenticator switch for dot1x, and port Gi1/0/2 is authenticating the Aironet via MAB to RADIUS. RADIUS is sending VSA device-traffic-class=switch to the 2960. The closet-2960 has no special 802.1x configuration, nor is it an authenticator switch; it just has a manually-configured trunk port to the user-area 2960 [for now; I'm trying to take this one step at a time!].
The user-area 2960 correctly converts port Gi1/0/1 to a trunk port when the Aironet is authenticated [via MAB]. The Aironet boots up, the port is opened, I can ping the Aironet on the native V LAN, and all is well [so it seems]. The Aironet dot11Radio is configured for two SSIDs and mapped to V LANs, which are being spanned via STP thru the user-area 2960 and the closet-2960. STP is correct and verified on all switches.
I have DHCP snooping configured on the user-area 2960 but only for V LAN 1 [but NOT the wireless user V LANs], the trunk port to the closet 2960 is a trusted port. Hosts on the wired ports on the user-area 2960 are able to get DHCP IPs. On the Aironet, "show dot11 associations" shows hosts on the SSIDs are getting DHCP addresses. Again, I am *NOT* running dhcp snooping on wireless SSID V LANs [i read elsewhere that can cause problems as users roam between Aironets].
I do have CISP configured on the user-area 2960. I do not have CISP configured on the closet-2960 [best I can tell, that's not required at this stage, but I could be wrong]. Despite the alleged documentation, I could not get the Aironet to use a dot1x credentials profile to authenticate to NPS/RADIUS as an 802.1x supplicant, which is why I resorted to MAB for this exercise. The Aironet simply would not run dot1x [best I could tell]. The documentation and configuration didn't seem complex, so I was quite confused.
I have upgraded the Aironet to the latest 12.4(25d)JA2 software, and the 2960 is at 12.2(55)SE7 [i saw 12.2(58) has some issues, but I'm willing to be persuaded otherwise, based on sound advice]. Ok, now the problem:
Users on the guest wireless SSID (V lan 20) say they cannot connect. Yep, classic. V LAN 20 is trunk and spanned to all the sufficient places. The Aironet shows users in the associations list for that SSID with IP addresses from the DHCP server! DHCP snooping is not configured on that V LAN. I read another support forum post saying CISP and MAB could cause problems with "disappearing" ARP entries. I appear to have that problem. However, the user on the Staff wireless (V LAN 10) has full access. Am I running into a problem with "multi- host" authentication config? Via tcpdump on my firewall, I see nothing but broadcast and multicast traffic coming from a host on VLAN 20. What puzzles me is how I do see *SOME* traffic from a V LAN 20 host on this SSID, but no uni cast traffic!
Since you're going to ask, here is my port config for this AP on the 2960 authenticator switch in the user-area, and the AAA config pieces:
#sh run br | in ip dhcp
ip dhcp snooping vlan 1
no ip dhcp snooping information option
ip dhcp snooping database flash:dhcp_snoop.txt
ip dhcp snooping

I just bought an EA-4500 and i am having problems with rebooting the device. Every time I change a setting and the router reboots it never starts up again - and the logo LED doesn't flash, it is on constant. I have to cut the power and wait for about 15 minutes, and then it boots up fine - logo flashing and all.
