Cisco Wireless :: AIR-CT2504-K9 - AP Keeps Rebooting
Nov 4, 2012
We have 1 WLC + 17 AP's on our main site and thats working fine... we just buyed a new AP for a new site of us. Its the same domain, same ip range nothing special at all... Somehow the AP on the site keeps rebooting and the users getting nervous of it there
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 !.
some computers is connecting to AP that is farthest, But there are two APS closer and the signal gets too low, the computer only connects to the closest AP if I disconnect and reconnect.I have 2 controllers series 2500 model AIR-CT2504-K9.
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.

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 ?
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 have AIR-CT2504-5-K9, with 5 access point license support. I buy capacity adder license LIC-CT2504-5A for add 5 access points more. When i try download licence file from tftp server on WLC system i see message "License 1 Failed 1" on WLC. TFTP server message downloading OK.

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:

I've got a new CT2504 controller with software version 7.0.220.0 Regarding to [URL]I've tried to configure the internal DHCP on a dynamic-interface, but this is not possible:(Cisco Controller) >config interface dhcp dynamic-interface vlan401 primary 172.16.x.3 vlan401 Interface IP can not be used as internal DHCP server IP It works, if I use another IP (aka DHCP server) in the same subnet or in another subnet. It works also for the management interface.

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 deleted the ios image form the aironet device from command line when i was trying to updgrade it.Now the aironet 1100 keeps rebooting.I've tried to hold down the mode for 30 seconds goes red, but keeps rebooting.
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.
I've got this weird problem with my AP. It keeps rebooting randomly. It happen to all the AP in my campus randomly. It happens recently. It have been commission for quite a long time. ie user able to connect and use it. its connect back to the controller to back in another campus. Below are the logs i gather.
*Jun 7 11:13:54.287: %LINK-3-UPDOWN: Interface Dot11Radio0, changed state to up *Jun 7 11:13:54.290: %LINK-3-UPDOWN: Interface Dot11Radio0, changed state to down
I've been having this problem the past 2 days. around 7-7:30pm my motorola sbg6580 will reboot itself every 15m or so the rest of the night.I've checked all my line they are in good condition, I've done the whole pull out all the cords let it sit for 1 minute, I've factory reset it.called the cableone tech support and it even reset while i was on the phone with him. I have a tech coming out tuesday but if it's something i can troubleshoot and fix now i'd rather have that.
I have a set up with an 5508 controller and some AP1141.i get this in the log

[code]....
The ap's are powered from a 3560 poe switch, have movet the ap's to another switch, same problem Controller is running 7.0.98.0
Recieved this E4200 as a repplacement for a v1 that kept dropping wireless connection. Now after about 1.5 months the router keeps rebooting. Tried resetting, etc...no luck. Calling Cisco now.
I might have to reboot my operating system, I have a Cisco wireless router, so I have to reset it, and set it up again after i reboot my operating system?
I recently updated the firmware to 1.0.02 on my E4200 and since then it's been rebooting randomly about once a day. It was working perfectly fine before the firmware update.
I have a problem with my EA4500. Router permanently rebooting. - router is not visible on the network. Ping to 192.168.1.1 - loss of all packets; - hard reset (30/30/30) does not work.
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.
I have 1242 Configured with 12.4.21a-ja1 and I have many of these. however I have 4 on the same location that have just started rebooting. The crashinfo logs ell me that cmd: PASSWORD statement not printed..Dont know if thats the issue....but something is wrong.. We are running SNMP and thats about it...
I have an E4200 v1 wireless router. Intermittently, my hard wired laptop (and hard wired desktop) loose Internet connnectivity and when I look at the 4200 I see the status light flashing slowly like it was just rebooted. I am runnong 1.0.04, have reset to factory, reflashed the 1.0.04 code and done a 30-30-30 reset (so far no drops since the 30-30-30 reset but we'll see).
