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.

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.
View 3 Replies View RelatedI have been experiencing random disconnection from the internet completely out of the blue lately. Router has worked great for a long long time. Now it just drops connection and is down for about a minute and then I can reconnect or reload a webpage.I have my xbox live and PC wired with a laptop wireless. It drops everything at the same time everytime. I hardwired my xbox to the modem and gamed all day. I would assume this could eliminate the modem as an issue. There isnt any inconsistencies with the router's colour or lights to my knowledge either.
I put a new Ethernet cable from modem to router to try and I thought it fixed the problem but it lasted problem free for about 6 hours then it crashed.
I have a Dell XPS 410 desktop PC purchased in 2006 now running Windows 7 (32-bit) that is hard-wired to D-Link 825 dual band N router.
The Problem- The desktop, when actively using the internet, will randomly lose connection to the Internet, then by just waiting, it re-acquires a connection. When it does this it sometimes also disconnects other laptops that are wirelessly connected through the same router, or at least slows them way down. Also similarly effects a hard-wired X-Box 360 (either loses connection all together or, the games start to severely lag) much to the disdain of my game playing kids.

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

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.

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:

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).

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.

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?

View 1 Replies View RelatedAironet 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.

View 3 Replies View RelatedWe 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.

View 5 Replies View RelatedI 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.
View 3 Replies View RelatedFirst, 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 only find out about it when someone calls me.From the affected computer:I can ping sites I can ping our Cyberoam UTM (which acts as our DNS, DHCP, and firewall)disabling/enabling connection doesn't fix the problem releasing/renewing ip doesn't fix the problem flushing dns doesnt fix the problem uninstalled antivirus on two test machines, problem still randomly manifests.replaced the Cyberoam with newer model users have claimed that if they wait a long period of time (40+ minutes) the problem sometimes resolves.rebooting the computer resolves the issue until it randomly occurs again changing the computer's mac address also resolves the issue until it randomly occurs again.
View 3 Replies View RelatedI just recently had comcast high-speed cable installed, and purchased a Linksys E2500 advanced dual-band N router to get myself going.

The complex is shaped like like an rectangle, fairly small, maybe 100 feet on the ends and 300 feet long on the sides. There are 130 people that we are assuming may have about 3 devices each that they will connect to the wireless network, potentially simultaneously, as this is in a college environment. We have plenty of bandwidth and down/up speed. We are running 30 megabit down and 10 up. I am planning on having a router with two access points centrally located in an apartment and extending the network out with antennas in each direction from the access points with Omni directional antennas. The Access points that I am planning on using are Cisco WAP200 with maybe a Linksys router, as the router should not have more than 10 connections on it. I need something that will not crash after 10-15 users connect to it because it jams up from overload.

So problem is with persistent disconnection from my landlord's wireless hotspot. The usual exclamation mark at the wireless bar indicating that I'm connected to the network but I don't get internet access...I've got the computer checked up by STAPLES where I bought it and everything was in perfect shape, network card fully functional... I mean it is brand new. They even reformatted the computer and installed clean Windows 7 with no crap software in it...I brought the computer to school and internet works FLAWLESSLY. Disgustingly fast.The problem is only when I'm at home where my internet would work fine for say 5 mins and then the exclamation mark will pop at the wireless bar and I would lose internet access for half an hour or more. I would get the access back and then it would disconnect again.
I called my ISP and they suggested to change my wireless channel to a unique # say channel 11 from 1-11. Turns out the wireless channel already is on 11... I then got it changed to 1 by my landlord. Still same situation. We then tried to change the wireless security encryption (e.g WPA-personal to WPA2). My computer can't connect in that case...On a side note I do have an older laptop (~7 years old), the one I had before purchasing this new computer. This old laptop can connect to the wireless and work PERFECTLY.
So the problem happens only with this new computer, and only at home. I'm completely clueless as to what the problem might be. It looks like some kind of interference but I've tried changing wireless channel (from 11 to 1) which didn't get rid of the persistent disconnection. Could it be interference with another computer that's using the same wireless hotspot in the house?

All seems to function properly: the clients are simple Android device and the connection appears solid.. We've a good roaming between access points (not seamless of course but is ok) and no particalur problems, also because the network is used to drive very LOW data (no internet): the clients opens a tcp connection to the server and sends only a keep alive packets over this connection.. Then sometime the server send a very small amount of data (some byte) to activate the display of the device and show a question.. the clients reply with some other byte of data and so on.. During an event of 3/4 hour we can do this 12/14 times, so the network load is nearly 0....
