Cisco :: Aironet 1142n WAP Setup
Oct 21, 2011
I am trying to configure an Aironet 1142 WAP model#AIR-AP1142n-A-K9. My setup is very basic, I have a router that acts as the DHCP server, the 1142n, and a PC. I am using the 1142n in Standalone AP mode no authentication, and have it working according to the [URL]. And it is working perfectly. My questions are as follows.
1. I have isolated the wireless users from seeing each other by using ap isolation, Can I prevent the wireless users from accessing the lan pc, router and WAP configuration pages? Is there any way to do that while still maintaining internet access? Basically I just want to provide my users wireless internet access without authentication but don't want them able to see each other or anything on the lan.

I just purchased an Aironet 1142n and need to configure/set it on one subnet in our WAN and ship it to another subnet on the WAN.
I have not been able to access the unit using a network cable from a pc direct connected to the Aironet. The pc's ip address is set to 10.0.0.2 I can not get to the access point thru the web interface using 10.0.0.1.
When I attempted to access it using a Hyper terminal connected to serial port and console port it loaded a list of software and updates and then reported that it shut down and I could not do any thing with it.
What must I do to be able to configuer a static IP and assign it an SSID and Security settings? How can I access the web interface? I have reset it by uplugging the power cord and holding down the Mode button while I plugged back in the power cord and holding it until the light turned amber/orange. Currently the light is solid green with the ethernet port direct connected to the nic card on a desktop.

I've just recently purchased the Aironet 1142n and am hoping to set it up as a repeater. I've followed the documentation here: [UEL] but am still having problems.
What I'm trying to achieve is: I have an adsl router (TP-link W8960N) at the front of the house but the wireless signal does not reach all the way to the end of the house. I am trying to set up the aironet 1142n to act as a repeater and place it in the middle of the house and hopefully that will extend the wireless signal to the end of the house and remove the dead spots. I would like to do this without having ethernet cables running all over the place and have been trying to configure the aironet 1142n to no avail. Every time I set the aironet 1142n to "repeater" it automatically coverts back to "access point" under role of radio network.
I guess my main question first of all is, can I set the aironet 1142n as a wireless repeater? And if so, where am I going wrong in my configuration?
I've just read that " Repeater access points running Cisco IOS software cannot associate to parent access points that that do not run Cisco IOS software."
Does this mean the aironet 1142n set up as a repeater will not work if the original access point (in this case, the TP Link adsl wireless router) isn't a cisco brand?

I have bought 2504 LAN Controller and my old 1142 wants to configure to accept that Controller instead of old controller. These APs and controllers in far away site and before I go there I want to figure out how can I do following.
1. How can I configure old 1142(Previously connected with another LAN Controller) to accept New 2504 Controller instead of old controller ?
2. What are the concerns do I need to consider?

We have some Cisco Aironet 1142N Autonomous access points installed, currently running 12.4(21a)JA1 IOS system software:
System Software Filename: c1140-k9w7-tar.124-21a.JA1
System Software Version: 12.4(21a)JA1
Bootloader Version: 12.4(23c)JA3
We tried to install the following Autonomous AP IOS software update:
Release 15.2.2-JA ED (c1140-k9w7-tar.152-2.JA.tar) 30-AUG-2012
But the 15.2.2-JA system software release does not install via TFTP Web-GUI (from a accessible PumpKIN TFTP-Server poining on that software update).
What's the problem with that?Is that system software release 15.2.2-JA ED (c1140-k9w7-tar.152-2.JA.tar) not compatible to the Cisco Aironet 1142N Autonomous access points

A Cisco RV220W router/firewall connects the local LAN to the internet. The router is connected to a new Cisco SG300-28P switch configured in Layer 2 mode. There are two new AIR-1142N wireless access points running in autonomous mode connected to 2 ports on the SG300 powered through PoE. The AIR-1142N access points are running the latest firmware version 15.2(2)JB. There are two VLANs defined: VLAN1 is the native on all devices, and VLAN2 is for wireless guest traffic to provide access to the internet only.Internal/staff traffic is on 192.168.100.x, and the wireless SSID is MYNetS.Guest traffic is on 192.168.200.x and the wireless SSID is MyNetG.IP addresses are being assigned by the RV220W.
All works well with one exception. Wireless clients on the internal SSID are able to ping/access the switch, router, and other clients on wired ports on the switch. The router, switch, and wired clients can ping wireless clients. However, wireless clients, on the same SSID and the same 1142N cannot ping/access one another. They are being isolated from each other. We absolutely need to have this capability.The SG300 does not have port security enabled on any port. none of the workstations/laptops have a firewall enabled. These laptops are all Macs btw. I have checked that neither of the 1142N access points have Public Secure Packet Forwarding enabled on either of the VLANs.I am at a loss as to why the wireless clients are being isolated.

I am trying to setup a Cisco Aironet 1041 on my network for WiFi authinentication and access and I do not have a Radius server and was wondering if it is possible to configure the 1041 to authenticate with just WPA or WPA2 and a PSK without any of the other configurations? This setup is only going to be temporary untill I can get the appropriate infrastructure in place to facilitate the Radius server setup I really want in 12 to 18 months from now.

I'm new to the Cisco Aironet Access Point. I got a new STANDALONE Aironet 1260 series access point device. The part # AIR-AP1262N-A-K9. The shipping package did not come with any guide, CD, and power adapter. I searched the Cisco sites, but could not find appropriate manuals. I did find a getting started guide but not for standalone AP, it's for Controller-based AP. Question - where can I find manuals / guides to set up and configure my new standalone Cisco Aironet Access Point 1260?

I have just setup a new WLC 2504 controller to manage a WiFi service that will span 6 geographic locations. The local networks at each location are on different subnets (all 192.168.x.x) and are linked up via IPSEC VPN links, and there is Active Directory spanning the sites, with DNS and DHCP servers running at each location.
I tested the WLC at our main office with a single AP, and it worked fine. The AP set itself up, and wireless devices connect with no probs. Great! Yesterday I headed out to one of our remote sites, and connected an AP to their network - and that seemed to work fine too. Within a few minutes I was able to see the WiFi network I'd setup, and my smartphone connected to it straight away (as I'd rpeviously connected at the main office), so I was pretty happy that all was working well.
This morning however I've had notification that wifi performance at the remote site isn't great. I've got someone to check their ip address, and I've found that their IP address and default gateway match the LAN at the main office where the WLC is based - NOT the LAN where the wireless client is. Obvioulsy this is not ideal!
(I guess I HAVE done something wrong!?). And how can I get wireless clients at remote sites to pick up an IP from the DHCP server at THEIR site?

I recently bought 6 airo net 1041N standalone access points for a customer of mine. It's an academy of barely 200 students. I'll be installing an access point in every room, to ensure better signal, since they use video for there classes. The reason why i decided to install an access point in every room is because the walls are armed concrete and they had a terrible experience with a past company in which they spend a lot of money for a antenna system that didn't work.These access points will be connected to a switch, which I have to buy also.Every student is going to bring there own laptops in order to connect to the network.
The reason why I'm writing is because I have a few questions to clarify.
1) What is the best position for better signal, top side wall or corner ceiling?
2) How many client mac address filtering can i do per access point?
3)I plan on doing ESSID but can I mac filter clients to a particular access point or should I mac address filter all permitted devices in all access points. The problem is that students come with iPods and phones and as you know on windows they will be able to see the wpa2 key and enter it on the particular UN-authorized device.
4) Any graphic user interface for configuring these access points or do i have to use Cisco IOS(kind of familiar with it)? (I'm used to GUI)
5)How can I configure these access points, through Ethernet browser or do I have to use console port cable?
6)Do I have to use POE injector or can I connect the access points directly to the switch with PoE and QoS?
7)I was planning on buying a small business switch sg100 d-8 but they recommended me that I should use the catalyst 2960 series, which would be best for handling video data? don't have to be much features, just QoS.
8) Can CCp software be used in these access points?

I have a Cisco Aironet 1240AG Access Point and I am trying to setup a guest network that is secure and limited in bandwidth utilization. I see an option under security > SSID Manager on the web interface to select an interface of Radio0-802.11G, Radio1-802.11A or both. Can I put the guest network on the Radio1-802.11A and make it more secure/bandwidth limited or does this option not matter?

When I attempt to change the pre-shared key for our wireless network "Engineering" I get an error that states ERROR" VLAN '122" doesn't exist on 'Radio1-802.11N 5GHz" (see Services> VLAN). When I check the vlan the box for the 5GHz radio is checked. let me know what the possible cause is? Here is the config:

I have my device configured, and it has an IP, subnet, etc.I currently have it connected with serial port to my laptop and used PutTy to get into it,
However, despite it having an IP, I cannot use the web browser with it! This is driving me mad. I want to use the web browser and not the CLI for everything. it has a BVI1 IP as well as an Ethernet address.

I have run into a major issue with an autonomous Cisco 1142AP. We were in the midst of a firmware upgrade when something went wrong and caused the AP to reboot in an error mode. Basically the unit was flashing Blue, amber, red. We unmounted the unit from the wall, connected to the console, and it would now only flash red over and over. We pulled out the cisco guides and performed a factory reset on the unit. This still does not work. and the contents of our flash directory is empty. All we get is a ROMMON AP prompt on the unit. If I issue a set command, I can see the default settings for IP, netmask, etc.
I cannot access the unit via the network, even after setting IP info and matching it up to my laptop. Since I have no network connectivity, I can't TFTP a new IOS file to the unit. I am stumped. How to get the config as if it was out of the box, or an alternate way to TFTP to the unit? [code]Notice the lines in red, I must have typed someting incorrectly.Now once the unit boots after being reset, I cannot even type in the CLI. Someting majorly screwed up here. Can the bootstrap be reinitialized?

Now, with all the unified communications, voice, video and data are in the same device, and I try to give priority to voice and some applications, but in the WLC I can not find the way to mark all that kind of packets.
Is it possible to do that? like in a LAN making the marking as voice, signaling and any kind of application? as I marked in all the LAN.
the equipment:
WLC 5508 v7.0.116

Need to configure Cisco 1142 N access Point togetherwith the Cisco Switch . I have a POE Switch 4510 and Cisco 1142 N Cisco AP . I have one management vlan 5 & User VLAN for WIFI VLAN 10 . The problem is when i make the POE port which is connected to the AP as trunk port means : [code]I am not able to ping the management IP allotted from VLAN 5 . However when i make it as access i am able to ping the managament IP . But for both the VLANs to work it should be in trunk mode & in cisco i can either assign the port as access or trunk .Post this i would configure the 1142 N with Cisco SG300-10P POE Switch . I guess if issue with my 4510 gets resolved the same way i can configure SG300-10P as well .

I have a question with the CAPWAP command. Typically, when I get 1142N from our provider, they have no configuration on them and all I need to do is enter 4 lines of code all starting with CAPWAP and then I have them join the controller and finish the config. This one I just received looks like it has an IOS image or configuration on it. (You can do a show run). I can: show CAPWAP - but I can not enter any CAPWAP commands. They are invalid input detected at marker. How to I get to the point where I can enter my CAPWAP commands ??

I have two SSID's configured and I want them both on G and N but it looks like the speed is some way limited to 54mbps. I guess the encryption is not the problem as it's ciphers aes-ccm which support higher N-speeds.
my running config attached, that should be lovely as 54mpbs is too slow

I am currently switching out our Cisco 1130 APs and Cisco Small Bussiness APs for Cisco 1142Ns (I will NOT be using a WLC),
I have setup the AP, and read about some issues with Multicast and Apple Bon. Services.
I ran the "no ip igmp snooping" command and it allowed be to access our AirPlay Devices (Apple TV, AirPort Express, Etc), however our 2 AirPrint devices (Xerox 6125N, & Canon IR3220 via AirPrint Activator) are not showing up at all when connected to the 1142 (they work everywhere else).
Everything is on the same subnet, and 1142 is connected to the same switch has the airprint devices, and one Apple TV.
Both our 3500 Series switches are connected via fiber, AP and AirPrint/AirPlay devices are in the same VLAN.

Somestimes the AP has up to 80 users connect to it.SOme recommends the AP should have between 25-35 users max.Any one know the recommend maximum number of users connect to a AP? And how can you tell the traffic going through the AP is congested?

My co-workers and I have been trying to diagnose a problem that recently started occuring on our AP1141N and AP1142N units. I have found a handful of posts that talk about this issue, but none with a solid solution. It seems that as often as every 24 hours, the radio interfaces change state to down, for seemingly no reason. Once this occurs, the only way to bring the radio interface back up is to reboot the AP. As far as we know, this wasn't happening until recently, when we enabled the "N" speeds. Things were working correctly for a year or two while the APs were configured just for b/g operation. The following is the only seeminlg-relevant thing that shows up in the logs:
*Nov 12 00:53:02.508: %LINK-5-CHANGED: Interface Dot11Radio0, changed state to reset
*Nov 12 00:53:03.507: %LINEPROTO-5-UPDOWN: Line protocol on Interface Dot11Radio0, changed state to down
Some additional info:
- All of the APs are connected to PoE Cisco c2960 switches
- We have tried both hard-coded radio channels, and non hard-coded
- We have tried various ways setting power inline negotiation
- We are not using a WLC
- System Software Version: 12.4(21a)JA1
- Bootloader Version: 12.4(18a)JA3
I have attached output of sh run, sh log and sh controlers dot11Radio0. (Another oddiy - the line %DOT11-2-RESET_RADIO hasn't shown up in the other logs I have viewed after this issue occurs...)
