I have 8 2504 controllers and each needs to have a minimum of 20 MAC addresses added. I would rather not add them one at a time but I don't see any features that allow for an import. Any way to do the import?

I configured a 2504 controller with two LWAPP Access Points, and I'm using two SSID's on the same controller, the problem is when the user tries to switch between SSID's he gets an error message saying that the other network is unavailable but if he disconnects from the first network and then connects to the other it works fine !.

On the WLC I've set DHCP address pool, everything seems fine after ap download image -> reboot -> hit "Enter" to start blar blar blar... however, after a few second the WLC will initial upgrade image again and again. it's like a non-stop process.
Attached is the start up message, as you can see, i captured it after the ap successfully boot up, and WLC initial another cycle of image upgrade.
btw, my network is flat, WLC & AP all in the same network.

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?

City A is the data center with 2 WLC (CT2504-K9) and a number of AP. City B is a branch with MPLS between A and B. Right now the APs at City B has joined the controller. Users at B is getting ip's assigned from DHCP at City A. How do I configure the WLC so users can get ip's assigned from DHCP server present at B. Option 43 is enabled.

I've just been tasked with setting up 19 AIR-CT2504 WLCs with AIR-CAP3502E APs. The primary objective is to maximize throughput from clients uploading LARGE files over the air.
I need to make sure I config HT 802.11n properly with no support for legacy clients in the 5Ghz band.

I have inherited a site where the builders have installed a 2504 controller with 8 access points. Unfortunately they have not created an ap-manager interface when they did the set up. Is there any way I can do this via GUI or command line without going back to defaults?

I am using two AIR-CT2504-K9 controllers
Product Version.................................. 7.4.100.0
Bootloader Version............................... 1.0.16
Field Recovery Image Version..................... 1.0.0
Firmware Version................................. PIC 16.0
and 20 access points AIR-CAP2602I-E-K9 Cisco IOS Software, C2600 Software Version 15.2(2)JA, RELEASE SOFTWARE (fc1) LWAPP image version 7.4.100.0
I created 3 SSID:
1. [WPA2][Auth(PSK)]
2. Web-Passthrough
3. [WPA2][Auth(PSK)]
Configuration on controllers is identical. High Availability is configured on all APs. First controller controls only those APs witch have SSIDs with [WPA2][Auth(PSK)], second controller is basically for APs with Web-Passthrough SSID. From the start I have problem, some clients who try to connect to SSID with PSK are dropped or can’t connect entirely, but when they go to the next AP they connect successfully. For example I have Android smartphone and Lenovo laptop, smartphone connects successfully but laptop fails connection to the same AP, but when I take it to other AP it connects successfully. Sometimes smartphones can’t connect too. When devise can’t connect to one SSID it can’t connect to other SSID either. Sometimes there are up to 20 clients tying to connect to the same AP.
When I look into logs, I get these two messages:
Jun 3 08:58:58 192.168.224.1 WLC1: *dot1xMsgTask: Jun 03 08:58:51.176: #DOT1X-4-MAX_EAPOL_KEY_RETRANS: 1x_ptsm.c:456 Max EAPOL-key M1 retransmissions exceeded for client 7c:e9:d3:f4:74:4d

We have just installed our first CT2504.After install I have found a dramatic drop in signal strength compared to the wireless survey result obtained.All of our site surveys include real world testing using an AP, in this case a AP1041N.In doubt I retested a section using an AP1041N in the same location as one of the recently deployed LAP1041N.
In the same location a LAP1041N has between -10 and -20dbi difference in SNR compared to the test AP1041N.For example locations that tested with -60dbi using an AP1041N have little to no coverage using the LAP1041N installed.This applies irrespective of the WLC automatic control over Tx power or manually setting the LAP TX to the highest level.

I have a CT2504 at a customer site which does not load the captive portal page correctly nor will it load via HTTP as opposed to HTTPS.So for starters I did what I do with all my CT2504's (which work fine), I configured my Guest network to authenticate via the default captive portal. I then disabled HTTPS and SSH and enabled HTTP managment followed by rebooting the controller. On boot, logging into the WLC management GUI is automatically presented via HTTP as expected.However when clients access the Guest network they are redirected to the Web Authorisation via HTTPS instead of HTTP?In addtion to the above the captive portal page does not display correctly.The preview via the controller works fine, but the client is presented with a page with broken links to the images i.e. the blue strip at the top and the Cisco logo on the right.

I´m trying to connect them to my WLAN, for throubleshoot I create a new WLAN with WPA2-TKIP and a PSK, the devices didin´t connect to the WLAN.I also change the security to WPA2-AES with TKIP, it didn´t work too.
My best choice was to disable every security configuration in order to began the throubleshooting from zero, but even with no Layer 2 and 3 security, the devices didn´t connect to my Test WLAN.
I´m using a AIR-CT2504-K9 WLC with two AIR-CAP3502I-A-K9 AP, all the PCs and other brand cellphones and tablets work well.
Also I have a SOHO router on the office, and the IPad connect without a problem with that WLAN, but I need them to connect to my Cisco AP.

I tried to upgrade the cisco boorloader pf WLC 4402 from version 4 to 7.2. I updated ER.Aes FOR 7.2 (EARLY RELEASE.aes). It was updated perfectly and then I rebooted controller....now i can only see blank screen from connected console.I tried the flash of other lan controller but its not working because the issue is in the ROM as the boadloader file is in the ROM which is corrupted now i want the solution to upgrade the boatloader file inside the ROM.

I've been configuring hundreds of 3602i APs via Prime without incident, but I've encountered 2 APs that get to the ap: prompt and doesn't proceed further. If I type boot, then they'll complete the boot process.
How do I configure these 2 APs so they will automatically boot fully?

I've had a Belkin N+ wireless router for about 5 months. I reset the router recently (using the reset option on the router itself) and now it doesn't boot up. The lights at the front flash as if its going through its boot sequence but it never stops. I left it for 2 hours while I went out and when I came back it was still going through the boot sequence.

We currently have 8 1242's and they all work fine, however we recently baught one 2nd hand one which was previously connected to a WLC, it lights up fine but it wont detect in IPSU even though the dhcp has assigned an IP to it. I would like to login through the web page to configure it but I am not able to do that either. It responds to ping fine though. So I no longer wont it be a LAP, so I tried to console in, to run flash_init etc. but when I try and give the <ESC> command (during the flash loader) it just carries on and ignores all input. I have used the correct settings Baud rate 9600, no parity, no flow control , databits 8, etc. but nothing happens it just goes through the boot and then asks me to press enter to input. i can then browse the directories and rename files. but I just cant get it to holt the loader so I can reset, I tried rename of config.txt and env_vars but that has't worked either. It keeps stating that it is looking for LWAPP/CAPWAP but unfortunately we don't have a WLC Is there another way I can reset it or is there some magic way in whic I can send the ESC command.

an Aironet 1252 which is failing on boot. When power on the access-point shows the error below.
WARNING: A memory error occurred during the system start-up self-test. The device must be serviced if the error persists.
The following commands can, optionally, be used to initialize the flash file system and the TFTP file transfer system:
But when this happen, I can start the IOS manually doing flash_init and boot in ROMMON. After do this commands, the access-point starts and works normally.
How can I check and correct the memory and solve this issue?

I wanted to upgrade our three WLC 4402 from software version 5.0.148 to 6.0.202.0. The upgrade on the first controller was working. Unfortunately he lost all the local management users and it's MAC filters, but restoring this was not the problem. After upgrading the second controller.... the device does not boot anymore! The alarm led is RED and I don't know what to do. The only way to get connected to the controller is via the console port. There I can see a "parse error" but I don't know if that is the problem. Please look at the "log" attached. I'm not sure if the red alarm led was there before upgrading the controller software because the device is located to another place. I'm really concerned about upgrading the third controller because it's the most important wlc.

We have owned a this router for nearly a year now, and recently it has been acting up.Today I added a static connection or something of the like for my Xbox, with the correct ip gateway and subnet mask. Since the restart it has never stopped cycling the boot sequence without end. The download lights cycle and the router light flashes constantly. And I am unable to connect to the router page at 192.168.2.1 So I cannot reset the router, the hardware reset button just momentarily pauses the endless booting process.

why my AIR-AP1262N-A-K9 will not boot all the way. It will get all the way to initiating the interfaces and stop. I can never get to controlling the cli. This is my first time with a cisco ap but from everything that I read it seamed very easy.
This unit from what I understand will work all on its own with no controller. Hence it is called a "standalone" model. Yet it seems to be looking for something to finish during the boot. Below is the out put during boot. The last line is where it stops.
r WRDTR,CLKTR: 0x8200083f 0x40000000r RQDC ,RFDC : 0x80000033 0x00000212

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.
