Cisco Wireless :: AIR-CT2504-K9 - Clients Are Dropped Or Can’t Connect

Jun 2, 2013

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

Cisco Wireless :: CT2504 / Bad LWAP Versus Good Standalone AP Coverage?

Jun 13, 2012

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.

Cisco Wireless :: CT2504 / WLC Captive Portal Not Loading Images Or Via HTTP Correctly

Dec 11, 2012

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.

Cisco Wireless :: CT2504-K9 / WPA2-TKIP - IPad And IPhone Not Connecting To WLAN?

May 22, 2013

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.

Cisco Wireless :: AIR-LAP1142N-E-K9 Interfaces Down

Mar 12, 2013

I have a WLC with, let´s say, 30-40 AIR-LAP1142N-E-K9. Since last November the following issue happened 3 times. One of the APs (it´s always the same unit) remains online but both WiFi interfaces appear down. I´m unable to put it back UP like if they were disabled. Then i have to reboot the AP and it starts working again. 

What could be happening? Should i open an RMA for this unit?

Cisco Wireless :: AIR-WLC2106-K9 / AIR-LAP1142N-E-K9 - APS Configuration

Aug 22, 2012

I've just bought an AIR-WLC2106-K9 and 3 x AIR-LAP1142N-E-K9 and I'm having a problem getting the AP's configured. 
 
Firstly, the controller did not discover the device when it was on the same sub net, I had to plug it straight in which is no good for wireless-n due to the 100Mbps port speed on the controller.  Secondly, when I am editing the AP through the controller webpage, none of the details are saved after applying changes (static IP etc).
 
I followed the Cisco quick start guide for the controller to get the basic config, radius server details etc in.  It is running software version: 4.2.61.0

Cisco Wireless :: LAP1142N Not Saving Config

I have a wireless deployment using a 5508 controller and 90+ LAP1142N lightweight access points.Everything is going relatively well, except I have about 3 that do not keep their config (hostname and AP group) past a reboot of the access point.When they do come up after a reboot, they go back to the default hostname of the mac address and are placed in the default-group AP group.

Cisco Wireless :: LAP1142N Connecting With AIR-WLC2112-K9?

May 29, 2013

I'm in the process of trying to get a used LAP1142N access point connected to my already established WLAN. We currently have 7 active LAP1142N, our controller is a AIR-WLC2112-K9, and I am only trying to add one additional access point. I say this access point is used because we purchased it used, given it's not out of the box and hasn't ever been active in my environment. So far what I've tried is initially connecting the access point on to my network (powered over Ethernet) and consoled in from my desktop. With this, I was able to see the previous configuration so I ran a write erase/ reload. The AP shows a solid green light, but doesn't receive any configuration from the controller even when plugged directly in to the controller (on ports 7 and 8). I'm new to wireless, but familiar with Cisco CLI and web interfaces. I can't necessarily tell if this AP is set to autonomous as opposed to lightweight, but that could be the problem. Otherwise I'm lost. I've attached text files with the boot from CLI and show run from CLI.Let me know any additional information you may need. End note, I'm recieving DHCP (you can tell from boot), but it's not the same subnet as my controller or other active access points.

Cisco Wireless :: Accessing WLAN Via AP Air-lap1142n-e-k9

Apr 17, 2012

We have a set up which includes several air-lap1134n-e-k9 access points. We're having problems with a specific laptop connecting to the WLAN which is accessible via the AP. We can see numerous different SSIDs available and when we connect to either of the two we have set up it says it is unable to connect. One of the connections, let's call it Internet, has Layer 3 security set up. The other connection, Web, has Layer 2 security set up. The laptop can connect to neither. It can, however, connect to other wifi in the vacinity including a wifi hotspot we set up on an Android phone.
 
The laptop has an Intel Centrino Wireless-N 1030 network adapter with current drivers. The WLAN's we've set up, Internet and Web, are both enabled for 802.11n.

Cisco Wireless :: AP LAP1142N Can't Join Controller - 4402

Apr 11, 2012

1) AP was originally running a standalone image.  I booted it into a so-called ROMMON or AP mode (ESC is the right key to make it boot into this mode).

I found a recovery image in its flash - c1140-rcvk9w8-mx. I made the AP boot from it by using "set" command and I see that it start booting using this recovery image. Here goes the question. Do all AP settings matter ? E.g. when I run "set" command from AP I see the following:
 
ap: set
?=
DEFAULT_ROUTER=10.0.0.1
Default_router=10.9.99.1

Cisco Wireless :: LAP1142N Cycling IP Addresses From DHCP

Feb 12, 2013

I have a LAP1142N that is connected to a 3560 nonPoE switch (using compatible power injector) that will not associate to the controller I have set-up. The wireless is existing and I have about 11 other APs connected to the controller with no issues. The AP will pull an IP address from DHCP running on the primary controller. The AP pulls a new IP address in roughly a minute. I set the pool to be 3 IP addresses and set a contant ping to each, there is about 1 request time out before the next IP address starts pinging. I went to the controller and pulled the following message error from the log.

*Feb 13 14:24:58.614: %LWAPP-3-HDR_ENCAP_ERR: spam_lrad.c:4216 Unable to encapsulate LWAPP header for discovery response; AP (APs MAC address)

I have tried a different cable, connecting to a PoE switch, different controller, larger DHCP range, hosting DHCP on the distribution switch, I am awaiting console access to the AP since this is remote work. The controller is running Software Version 5.1.151.0. Thoughts?
