Cisco Wireless :: WLC 5508 / SW 6.0.199.4 / 1142 AP / Clients Getting Dropped?
Apr 14, 2013
We have deployed a WLC 5508 w/ SW version 6.0.199.4, 1142 AP's & open authentication w/ MAC filtering. Clients are randomly getting dropped with "Limited Access" shown in Win 7. In this state, the client machine is unable to ping the gateway and sometimes lose their DHCP assigned IP as well. A manual disconnect/re-connect to the SSID is required everytime.I ran a debug on one the clients stuck in the "Limited Access" state (debug client xx:xx:xx:xx):

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 a Cisco 1142 AP which has been suffering chronic connection drops to Mac OSX clients.
Sometimes clients go for days without an issue. Other times, connections drop several times within a 15 minute period. Problem seems to be independent of location with regards to AP. It happens when the client is within 20 feet, visual sight. [code]

We are about to upgrade our training facilities wireless and i have a few questions regarding the number of active clients we should target our design for.
We would be using 1142 and 3502I access points. I was thinking that based on the belo we'd be able to support around 30-40 clients per AP.

Type of web use
Amount of bandwidth allocated per device

We did wireless coverage testing using some 1142 units in autonomous mode, and got a satisfactory result, but upon converting these test units to Lightweight and adding them to our WLC5508 controller, the coverage has decreased noticeably.
Any tips or tricks to getting lightweight 1142 APs to have a range as far as the same hardware with autonomous firmware?

Doing segregation of SSIDs Base on AP , I have the following scenario:
Head Office :
2 SSIDs (HO_WiFi , Guest) , Access Points which are working in connected mode and grouped on the default ap group .
Remote site:
2 SSIDs (Branch_Wifi , Guest) , Access Points working in flex connected mode and locally switching the traffic .
As shown above , I will be having Head Office , and other 20 Remote Sites with Access Points working in Flex connected mode. What is the best way to group AP and segregate SSID base on location. Above Scenario are build base on WLC 5508 and AP 1142.

Access points 1142 controller 5508 running code 6.0.196.0 When you set the access point port speed with "config ap duplex full speed 1000 all" the access points leave the controlle and do not rejoin. I have had to reset the the access points manually with a power down and hold the reset button.

After the upgrade of the WLC 5508 to version 7.4 the 1142 access-points LED blinking rapidly cycling through blue, green, and red. I found the following information to this behavior: "Access point location command invoked"
The configuration didn't change. How can I switch this function?

This first started when a user said they were getting disconnected and reconnected a few times a day to our wireless network. He is in a remote office with a 1142 which is set to H-Reap talking back to our 5508. Our WLC is running 7.0.166 The laptop has an intel ulitmate 6300agn wireless card with the latest 15.x drivers.
We are using an SSID with wpa2 and 802.1x auth back to our ACS server using PEAP with our windows credentials.attached is what i am seeing on the wcs troubleshooting page.When i do a debug client on the WLC i see many reauthentications coming from the client on the different radio.

I am trying to setup two Cisco 1310 bridges (AIR-BR1310G-A-K9-R) for connectivity between two buildings. No external antennas have been setup yet and I am just setting the basic configuration.One is running c1310-k9w7-mx.123-8.JEA3, the other c1310-k9w7-mx.123-7.JA1,setup as a root-bridge, the other as a non-root bridge.However, even after disabling authentication and encryption, both units are still not talking to each other.Maybe a second set of eyes can see an issue?

I have a WPA2/AES network with PEAP MsChapv2 authentication. I have 2 ACS servers for authentication. The problem I have is dropped clients. Both ACS servers are setup identical. The database replcation has been preformed.A series of 10 clients connects wirelessly and they are all successful. ACS server 1 is the primary and ACS server 2 is the backup. We verified that the 10 users authenticated to the primary ACS. My time out to reauth is 30 minutes on the WiSM. 10 minutes into the test we took down the Primary server. This should have had no impact on the clients. 5 minutes later the clients lost thier authentication and were dropped from the network. They were able to reconnect by shutting down thier wireless client and reconnecting. The authentications were seen on the Backup ACS server.on a test of falling back to the primary the same thing happened again to the clients.

We are implementing a new corporate headquarters and have bought a Cisco 5508. I have two connections plugged into the 5508 in ports 1 and port 2. Port 1 is for all internally wireless networks and connects to our core 6500 and use an external DHCP server scopes. Port 2 is for our guest WLAN and connects directly to a public network switch in front of (outside) the firewall. For the guest network, I have setup a vlan on the controller for dhcp and the interface setup to that vlan and dhcp scope built on the controller. how or can I NAT the internally addressing for the guest network to the public IP address on the controller. Essentially I want to drop of guest network traffic outside the firewall and not have to deal with setting up the firewall for any aspect of guest network traffic.

i have a Setup as Follows
- 5508/1142
- heterogenous Client with WZC, XP, SP3, SSO
- ACS 5.2, MS AD
Target is Songle Sign On wih Machine Cerificates against AD. For testing purpose we tested with EAP-PEAP/MS Chapv2 and Machine Auth, works fine. Now we installed a Machine cert in the Machine cert Store (no User Cert) and reconfigured the WZC for using certs and Machin Auth. What we see is an Error Message in the System Tray that there is no certificate available. We checked it again, the MMC shows us a Machine cert in the Store.

We recently had a power outage where most of our AP's were down as well as our controller. When everything came back up most of the AP's didn't rejoin the controller without me resetting all of them. It seems as if the AP's might have booted up before the controller was up, but shouldn't they just try to rejoin at a later time? They didn't rejoin for 48+ hours on there own so I'm assuming that they were not ever going to re-join. All I had to do to fix it was power them off and back on and everything worked.
DHCP is on the local switch where the AP's are powered from so that's not a problem, and they had connectivity to the controller the whole time.
5508, and 1142's.Software version 7.2.103.0 on the controller.

I have configured 5508 with multiple APs but clients on the internal SSID aren't getting an IP address. I have the IP helper address configured and I have also disabled DHCP proxy on the controller.
I get the following from the client debug, I don't know what the below mac address is, it's not one my APs or the clients, I am not seeing this mac address on the controller at all but it shows up in the debug.
type = Airespace AP - Learn IP address

I'm having a problem with my clients dropping the network connection constantly throughout the campus. I am using a Cisco 5508 controller and the APs are LAP1141N. At first I thought it was a roaming issue but I tested with only 1 AP and the problem persisted, I can tell you that we don't have interference problems and that our old linksys APs used to work without flaws.

I have a 5508 WLC with CAP3502i APs connected to it. I upgreaded the code to the newest 7.2.115.1 code. I am having trouble with laptops that are not physically moving but are moving their connection from AP to AP in the same area. This is in a school and causing a problem with a testing program they are using becuse they drop 2 or 3 pings in the process. I do have the area heavily saturated with AP but that is because of the amount of clients we have connecting to them. There is 8 classrooms in a hallway with 24 laptops in each classroom. Each classroom has an 3502i ap in it. The laptop can be connected to an AP with great signal and move to another AP that still has a good signal but not as great. I don't understand why if I get 4 bars and connected at 144mps it would move to a new AP. These are Lenovo laptos and i have updated their wireless card drivers and set the roaming agressiviness to low but it still happens.

I have a WLC 5508 in my datacenter, and 1142s configured with FlexConnect at a remote site.Two issues:Some APs 'die' from time to time where I cannot ping them anymore and they do not service any clients. I can reset them from the WLC after which they work again. I have some clients in the building (same area) who lose connectivity from time to time and are unable to reconnect to the wireless. I am seeing errors that the gateway cannot be found or there is not a valid IP. restarting the AP closest to the clients fixes the issue. I have replaced the AP and connected to a different port on the switch.

We got a question about our WLC 5508 single controller deployment with 14 access points without a VLAN configuration.
When our clients connect to the wifi, we cannot see any ip address of them in the client details page. It shows everytime the ip address 0.0.0.0. The clients are configured with a static ip.

question in regards to the deployment of a new WLC and new LAPs,I have configured and connected a 5508 WLC and 3500 series LAP.LAG is enabled in the WLC and successfully connected to the neighboring switch (using etherchannel) and to the network.
The port-channel port is set to trunk mode obviously and certain vlan ids are currently allowed (3-5)
The management interface has this IP address 192.168.5.250/24
I created a WLAN with WLAN ID 3, Interface set to Management and say SSID test1
I have connected a new LAP to the network, which switchport interface is set to access mode and assigned with vlan id 3. The LAP is able to join the WLC successfully with an IP address, such as, 192.168.3.100 (assigned via DHCP).
When I try connecting a mobile client to the wireless LAN, it can successfully detect and connect to the WLAN, created in the WLC (test1) however it gets an IP address by DHCP, in the 192.168.5.0/24 network, which is the IP range of the management interface's IP address.
What can I do to get the clients connecting on network 192.168.3.0/24? I thought this would be the case since I allocated the WLAN Id of 3 in the WLAN test1 configuration and since the LAP switchport is set to access mode with vlan ID 3.

We have a Cisco 5508 controller with 1142 LWAP's running version 7.4.100.We have several Dell laptops which will not associate to the access point UNLESS you stand directly underneath it, power off the wireless, turn it back on then eventually the PC will associate to the AP.Once the PC is associated to the AP and user is authenticated then all is well.
Have tried updating the wireless drivers downloaded from both Dell or INTEL. This does not happen to all of our laptops. However, without making any changes to the WLC or the PC's, we have begun to expirence this problem with laptop which previously did not have this issue.

I'm working on migrating autonomous WAPs to lightweight mode in a WLC 5508. Some of the older WAPs are being decommissioned at the same time.
One issue I have found is that after replacing an old WAP in autonomous mode with a new WAP (3502); some clients near the coverage of this new LWAPP are now connecting to another WAP in autonomous mode that has not been converted or replaced yet; but that is located quite far away from where these clients are, actually two floors down. Users on these clients have reported wifi dropouts, which is obvious due to the distance where the old WAP is. A workaround that seems to work is removing the wifi profiles in the client machines and recreating them again, which is not a good solution for all of the wifi profiles we have in place. At this point of time we still need to have the older WAPs until they are all replaced.
How can I get clients connecting to a LWAPP that is closer to their location? I'm wondering what causes those clients to look for an existing older WAP rather than connecting to the new LWAPP, which is broadcasting the same SSID closer to where they aree. Bear in mind that the new LWAPP is working fine and has live sessions working just fine.

Just inserted a new 5508 WLC into the network. We current have 3 4404 WLCs, and there was a need to duplicate, as much as possible, the configurations on the 4404s, and the design. The 5508 came online as expected. We moved a few access points over to it. The APs got the correct address range. The clients are expected to get addresses in the same scope range as the APs. However, the clients are receiving addresses in the management IP scope.I know there are two "not a good way to do it" in here. Why is the management address range in the DHCP scope, and why are the clients using the same scope as the APs. We are going to change that. For now, the AP and client in the same range has been going on since we rolled out wireless in 2006.The 8 ports on the 5508 are configured for LAG. There is no dedicated port for management. They tell me not to do that on a 5508.

I have a 5508 WLC and 40+ LAP1142N APs spread across 19 locations that allows staff to connect to our private network via wireless. I recently deployed about 40 new laptops all identical make and model HP ProBook 4530's and all have the same client setup for the wireless. Out of those 40 laptops I have 4 that will not connect to the private network. However, these same laptops will connect to my public, open wireless network without issue. In addition to the 4 that will not connect all the others will prompt twice for network authentication.Now, I have about 10 other laptops that are not the HP model and all connect without issue and without dual propt. I don't think this is a wireless network issue but could be some type of issue with this model of laptop.

which is the maximum number of simultaneous wired guest clients on a 5508? And in a 2112 controller?
Wired clients count as wireless clients??
What about anchoring limitations, what is the effect of wired guest clients on the anchor controller?

We have 2 WLCs, 4402 (main) and 5508 (backup). While we turn on both devices, 4402 have 10 APs, and 5508 have 10 APs as well. Total connected clients will be 120+, but when we turn off either 1 wlc, let's say only 4402 is power on, total 20 APs joined, but the total client will be 90+, never reach over 100 clients. The same happened on 5508, is there any maximum associated connection on WLC?

I have a network setup as live-ssid. It is using the Interface for VLAN 14. All APs under the default-group AP Group obviously allows clients to DHCP an address from VLAN 14. This is working fine.
I created a new AP Group called 3rd Floor. This has the live-ssid setup, but instead of using the Interface for VLAN 14 it is setup for the Interface for VLAN 50. I have all the APs on this floor moved to the 3rd Floor AP Group.
The problem is that 95% of the clients on 3rd Floor are still picking up DHCP addresses from VLAN 14. I checked and all the clients are connected to the APs on the 3rd Floor. Only 4 Clients are getting an address from VLAN 50.
I'm not sure if something is configured wrong or not since some devices pick up the new VLAN and the rest don't. I've manually reboot the APs on the 3rd floor to see if that would fix it.

I would like to share one problem with WLC 5508 . we added a new virtual interface on the WLC. One new SSID is associated with this interface.
We created a ACL for this interface to restrict the access via WIFI to certian services. It´s not correct that everything works fine because the change were not applied. [code]
The changes of the ACL are applied on the fly, but for reason we don´t know, the clients don´t get a DHCP IP-Address (after changing the ACL) until the Controller is rebooted.

I work on a college campus that has thousands of students a day accessing our wireless network. We have broadcast SSID that the students use to connect to the internet. The students usually have more than one WiFi enable device on them and their laptops and phones both take an IP address, but they are only using the laptop to authenticate while the phone is associted, but not authenticated. In the meantime, I have several thousand IPs being used by their phones/iPods etc. Is there a way to revoke the DHCP lease if the client does not authenticate within a specified time frame (i.e. 10 minutes)?
