Cisco Wireless :: AIR-LAP1242G-E-K9 Does Not Work With AIR-CT5508-K9
Mar 11, 2012
we do have a site where we need to deploy AIR-LAP1142N-E-K9 and AIR-LAP1242G-E-K9 APs. We have two AIR-CT5508-K9 controllers with SW version 6.0.188.0.AIR-LAP1142N-E-K9s work okay, as expected, we do not have any problems with them.However AIR-LAP1242G-E-K9s do not, there is a problem with establishing CAPWAP tunnel with the controller.The AP is seen on the controller for a while, with 0 time up-time, cannot change any settings on the AP via controller, and after a while it disapears from the controller, apears again and this repeats.
The APs and controllers are connected to the LAN campus.Controllers via two 1G links configured as Etherchannel to WS-C6506-E VSS switch with s72033-ipservicesk9_wan-z.122-33.SXI1.bin on it.APs to WS-C3750G-48PS with c3750-ipbasek9-mz.122-50.SE2.bin on it. 3750 is connected to the C6505 via two 1G links configured as Etherchannel.Below I copied the log I captured on 1242 and the controller. Highlighted ones are the ones which I think might bring a clue.
I performed some troubleshooting steps.
- As we have some other controllers available over WAN, I tested the 1242 AP with 2100, 4400 and also with the same model AIR-CT5508-K9 with SW version 6.0.188.0 over WAN and this worked always okay.
- I wanted to be sure that I eliminate any kind of out of sequence packet issue, so I brought down all redundancy L2 links so that the L2 path from the AP to the controller was only through one leg links.
- I also brought the second controller down to eliminate potential issue with having two of them up.
- The AP gets its IP from DHCP configured on the C6506 switch, I am always able to ssh to AP, so the IP connectivity does not seem to be an issue.
- I have more 1242s, all behave in the same way. I also connected them to some other 3750 switches we have in the campus, always the same.
- As this seems to be maybe a kind of ssl issue, I tried to play with controller settings, like enabling Accept... options under Security/AP Policy,but this did not work.
- I also tried to reboot the controller, no improvement.
- The APs came from the factory, so in the beginning everything was factory default in them. They were always able to download the image from the controller in the very initial phase. I still do have some of them untouched, so I can perform any troubleshooting steps with the fresh one.I can reproduce this, can also send debugging logs if needed.

I have a AIR-LAP1242G-A-K9. I have several question:
1. Does the antenna is a MUST for it to work. 2. If I have a 1 unit of AIR-ANT2422DG-R (antenna) , does the wireless access still work? Do I need 2 antenna 3. If I have a 1 unit of AIR-ANT2422DG-R, does 802.11 b supported.
I have several Lightweight APs (AIR-LAP1242G-A-K9) runing of a single WLC. We keep getting devices, sometimes all devices, losing network signal. The WLC is running a global power setup so all APs have their power set automatically. The setting for power parameters are default. I have noticed when I run a client test the APs run at 11Mbps while the client devices run at 50-54Mbps. The protocol used by both devices is 802.1G. These network drop offs are frequent and I should say may well be an issue with the client devices although there are several different types of devices experiencing this issue. My question is should the TX and RX rates be the same? Is it ok to have this disparity in the TX/Rx values?
I'm working in a campus environment that has an existing wireless network using a Cisco AIR-WLC2112-K9 controller.There are 8 AIR-LAP1242G-A-K9 access points connected to the controller. Each access point has a 5.0GHZ 4.5dbi Cisco omnidirectional antenna, although the AP only supports 2.4GHZ.
Q1. Why a 5.0ghz antenna might had been used with a 2.4ghz AP, and if we can expect increased performance if we replace the antennas with 2.4ghz ones?
Q2. On the controller, the antenna gain is set to 0 for each AP. Is there also a benefit to leaving that 0 as opposed to 9 for 4.5dbi?
I am working on installing a new 2500 Controller with 2 AIR-LAP1242G's attached to it. I have both registered and on the controller but I am having trouble moving one of them to a new IPS AP group that I created. Furthermore, I noticed the default gateway is missing from the static ip settings and I am unable to add that as well. When I add the default gateway and hit apply, the controller does nothing. Same thing for when I try to change my WIPS device to monitor mode.
A couple other things that I noticed is that when I go to AP groups and try to remove the AP's from the default group, there is no remove button when you go inside the default group like I see when i go into my IPS group.The AP's are on software ver 12.4(23c)JA3 Boot ver 12.4.13.0 and the controller is at 7.0.22.0I have already power cycled the controller and both AP's.
I've two wlc model CT5508 version 7.0.116.0. They are working fine except for the RF grouping part. When I look at the RF Group members part in the configuration, I can see only one wlc (the one I'm connected to). If I connect to the second one, in the same part, I've just one controller (so the second one..). I tried to restart the algorithm but no change. Each controller is configured with Group Mode set to auto, and their respective role are auto-leader...I tried to change the RF group name on both wlcs, but it didn't fix the problem. When I look at the logs, there is one which appear quite often:
*emWeb: Nov 29 10:32:07.764: %LOG-6-Q_IND: dtl_arp.c:2581 ARP input q exceeds limit. Current val = 50 [...It occurred 38 times.!]
I have issue about Wireless controler , i have 2x WS-C3750G-24WS and 1x AIR-CT5508-50-K9 , i have max 50 access point license and i can't upgrading because WS-C3750G-24WS is and of life , can i use AIR-CT5508-50-K9 with 3750G to work together? , mobility and everything....
i received access point types AIR-LAP1252AG-E-K9, which i want to connect to my wlan controller AIR-CT5508-K9. Update from IOS etc. is working fine. Also all access points are recognized by the controller.We got the AIR-LAP1252AG-E-K9 with two antenna versions.
What is the operating and/or peak power consumption (in kW) of a 5508 WLC with redundant power supplies?
The below power details are from the 5508 datasheet which lists 115 W as the maximum draw (0.115 kW) however this seems a bit low, is this right?
Input power: 100 to 240 VAC; 50/60 Hz; 1.05 A at 110 VAC, 115 W Maximum; 0.523 A at 220 VAC, 115 W Maximum; Test Conditions: Redundant Power Supplies, 40C, Full Traffic. Heat Dissipation: 392 BTU/hour at 110/220 VAC Maximum Cisco 5500 Series Wireless Controllers Data Sheet: [URL]
My understanding is rigister LIC-CT5508-UPG/PAK number on cisco site and get .lic file however what is the use of other PAK where do i register this files with? Moreover , we do have NCS , MSE in place which is centralised devices.
I am running big wireless network, with 20no of 5500 with 7.0.116.0 version. I have more than 20,000 AP's. If i add some config in primary controller or do some changes or reboot all the AP's are moving to backup controller. this doesn’t have any problem, but many AP's which moved to backup controller are losing VLAN mapping. This happens every time. Primary --> backup, backup --> primary. Both controllers have same vern...same config etc..
AP model: AIR-LAP1252AG-A-K9 Controler model: AIR-CT5508-K9
When a client connecting to a specific AP (example AP01), after every 1800 sec uptime it will reconnect and join other unit AP (example AP02)Both AP physically installed distance is around 6 meters from each other. I conduct the testing where i get myself sitting in middle between these two APs.
01. If i disable settsion timeout this feature, or setting the seconds become higher value, what's the performance and security impact? Is it recomend to change the default 1800 seconds session timeout?
02. Is there anyway i can tweak on WLC controller to prevent the client after session timeout then associate with another AP. This will lead major performance impact as the client woudl possibility connect to the weak signal AP and effect on the performance.
These are the details for reference:Client detail

Q: a client has a network with 60 AP's controlled by a AIR-CT5508-50-K9 (+ L-LIC-CT5508-25A) with a redundant power supply. Can he get full redundancy by purchasing a second controller? If he purchases one, can he bring it into the network? What about the extra license for 25 extra AP's installed on the first controller?
Main Site: WLC AIR-CT5508-50-K9 WCS 6.x for 50 APs (32 ) AP 1140
02 Remote Sites : 03 AP 1140 using H-REAP
Now, my company is considering to implement a wIPS solution, so i planned to install in the Main Site a MSE3300 and (01) AP 3500e as a wIPS AP Monitor in the remote sites,
Need to confirm:
A) Can an AP3500 work with HREAP and as wIPS monitor AP at the same time? or in other words, if it is possible to have an AP wIPS monitor far away from the WLC (over the WAN)?
B) What are the requirements of WAN link if I want to install a Centralized MSE 330 Engine,which perform the wIPS solution in all the network.
Some of my Lightweight Access Points lose connection every 10 minutes now, it worked without problems before.
I'm using an AIR-CT5508-K9 Controller with Version 7.0.116.0 and AP are all AIR-LAP1242AG-E-K9.
In the log I find informations about my node changing his parent and then reseting the radio interface.
I checked my configuration, but perhaps I missed something.

Is there any chance the Wireless Repeater mode work with WPA2-AES ?If not, which model of AP should I buy to connect it with my wap54g as Wireless Repeater?
I have a DIR-655 B1 router. The firmware is 2.00 NA. Just to clarify, the DSi itself does work with WPA, but the games only work with WEP. I made a guest account and set it to WEP and it still does not work. I have tried making the main connection WEP as well, but when I go on the game and try it, it says it is WPA and not WEP. My friend has a DIR-655 as well, but the hardware and firmware version are different. Her games work flawlessly.
I purchased 3 of these Wireless-G access points and none of them are plug and play. I am here because I have spent the last three hours trying to go through every step they suggest in the Quick Start Guide.
I tried entering in a web browser the default IP address and wait for a login that does not appear.
I've been asked to configure an 881 with a Verizon 3G backup connection as a backup to the FE4 primary WAN connection. I've been unable to get any connectivity through 3G, and in most cases, as soon as I try to configure 3G, I lose connectivity through FE4.Currently, I don't even have FE4 connected. I'm just trying to get the 3G connection working, so then I can take it back to the office and have a functional 3G backup connection. [code]
Have a Fujitsu Siemens Esprimo P2430 PC and am trying to connect it to my Virgin Media super Hub via a Netgear WN1111 USB 2.0 AdapterWireless-N. Software is loaded perfectly fine and signal is excellent but it refuses to load any web pages unless I refresh a zillion times. Internet works excellently on my laptop so am stumped. No connection malfunction is diagnosed
I want to get wifi for my laptop and ipod at work, i cannot add a router to the system lol not a option. Is there a thing i can plug into the dekstop here so i can get the internet off of it? There has to be somthing out there that can do this. Because these computers are wired.
I bought cisco AP (air-ap1142-e-k9) and we know this ap works with 802.11a/g/n same the description note on the package cartoon but my problem is when i configure that ap its work only with 802.11a/g i tries to make it works with 802.11n but fail .
I currently have a UC540 system with 12x aironet 1130 APs. Seamless roaming does not seem to work, and the recommendation seems to be to introduce a WLAN controller.
The story is that we recently upgraded our 4404 controller to the new 7.2.0.230 code. This upgrade was from 4.2.209 code. I would like to make the change to the Multicast setup so that It is multcasted and not unicasted.So I went into the controller and selected MULTICAST for AP multicast mode and entered in a multicast ip of 239.255.1.60 ( default choosen in the cisco howto's)I then test the reason for enabling the multicast and it doesnt work. The problem is that the Wireless HP printers setup to use Apples IPRINT are not able to be found. However, when I select the Multicast setting for the APs to be UNICAST the Ipads can find the Printers and print to them.What am I doing wrong with this Multicast setting? Do i need to add a Multicast address to the router?
