Cisco Wireless :: 5508 Dell Wi-Fi Clients Not Automatically Associating To AP

Apr 16, 2013

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.

Cisco Wireless :: 5508 Does WCS Automatically Reset Radios

Feb 8, 2012

I have a WCS, four 5508 controllers, Cisco 3750X switches, and both autonomous Cisco 1200, and LightWeight 3502i  in service.The problems I am having, is that some of my Access Point reset for no apparent reason, and I get alerted by my NMS.When I look at the switch port, that connects an access point that reported down, I see the POE switch port went down and back up in 4 seconds, just long enough for the access point to reset.There are no errors on the switch port(s).  No cable or speed/duplex issues. Switch IOS: c3750e-universalk9-mz.122-55.se1

There are no other pertinent entries in the switch log.  Just that the port went down and then back up. Always in 4 seconds.When a reset happens the WCS reports on the access point: '802.11/b/g/n' interface of AP associated to controller 172.20.0.x is down. Reason: Indicates that while the radio state should be updated on controller, no reset should be reported.But nothing else, except that the radio came back up.
 
This is happening two or three times a day, and rotates. It seems that it never happens at the same time of the day, or the same access point, or the same switch.  (I have over 1000 access points and 500 switches in service)I am curious if the WCS is automatically resetting the access point radios, which is causing the switch port to go down/up?And if so, is it possible to turn off the automatic reset?

Cisco Wireless :: 5508 - Replicating Between Controllers Automatically Without HA?

Jun 11, 2013

We have 2 Cisco 5508 WLCs, each wtih 50 licenses. What I would like to do is split the 50 odd APs between the 2 controllers load balancing the traffic. If a controller goes down or there is a break in the path all APs would failover to their configured secondary controller.  So far so good.
 
However there seems to be no way to 'replicate' the configurations between controllers unless I setup HA  , but as I understand it HA is Active /Passive, so essentially, unless you get a failover situaltion, completely 'redundant'.
 
Is there a way or either replicating between controllers automatically with out HA, or is there a way of making HA Active / Active?

Cisco Wireless :: How To Prevent Certain APs From Associating With WLC 8.1.185

Mar 29, 2012

We have 9 WLCs around a corporate network.  Each of the WLCs was in the same mobility group for failover purposes, and to permit APs to reconnect back to their primary WLC in the event of a failover.
 
However one of the sites has now been sold and pending separation of the LAN infrastructure the APs need to be isolated and prevented from associating with any WLC other than their primary (on site).  From our experience once the APs know about other WLCs they retain this list in NVRAM even if the secondary WLC is removed from the configuration they will still associate with one of the known APs if possible (Cisco document this). WLC v 8.1.185.

Cisco Wireless :: 5508 - Clients Not Getting IP Address

Nov 23, 2011

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.

Cisco Wireless :: 5508 - Clients Dropping Connections

Jan 22, 2012

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.

Cisco Wireless :: 5508 WLC Clients Jumping From AP To AP In Same Area

May 1, 2013

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.

Cisco Wireless :: WLC 5508 Clients Disconnect / Not Able To Reconnect

Jan 22, 2013

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.

Cisco Wireless :: WLC 5508 Clients Show IP Address 0.0.0.0

May 16, 2012

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.

Cisco Wireless :: WLC 5508 - Get Clients Connecting On Network 192.168.3.0/24?

Aug 6, 2012

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.

Cisco Wireless :: WLC 5508 Migrating With Clients Connecting To Old WAPs?

Aug 26, 2012

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.

Cisco Wireless :: New 5508 Not Handing Our Correct IP Address Scope To Clients

Jan 15, 2013

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.

Cisco Wireless :: 5508 WLC - Clients Unable To Connect To WPA2 AES Network

Jun 12, 2012

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.

Dell :: Inspiron M5110 - Laptop Will Not Connect To Wireless Automatically After Sleep Mode

Feb 10, 2013

I have a Dell Inspirion M5110. Windows 7, 64 bit.

When ever I open the lid to the laptop it takes 5-10 mins before it will automatically connect to a network. Diagnose this network does not find anything, nor provides any troubleshooting.  Typically if I open the network connections center and disable the wireless, let it sit for 30 secs or so, and re-enable, it will finally connect.

I know it's not my router, as the laptop does the same thing at work, and multiple different friends house.

I've confirmed that DHCP is set to automatic connect. I've also checked Device Manager/Network adapters/ and unchecked the box "allow the computer to turn off this device to save power"

Cisco :: Maximum Associated Clients For WLC 4402 And 5508?

Jun 22, 2011

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?

Cisco :: WLC 5508 AP Group - Clients Using Wrong VLAN

Feb 14, 2011

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.

Cisco :: WLC 5508 - Clients Can't Obtain IP Address Via DHCP

Mar 29, 2012

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.

Cisco :: Clients That Are Not Authenticated Taking IP Addresses - WLC 5508

After some hours my laptop dies, I found it tourned off and it didn't start again. So, afert two days, another technical Dell changed XPS17 's motherboard and the power connector. The same day I worked with my notebook without any problemes, but at the end of my workday I shut down the system (Windows server 2008)  and It restart automatically. I tried again more than once, but at the end my laptop restart automatically again (I have two partitions: Win 7 and Win 2008 server Both OS has the same issue: automatic reboot afert shut down). This morning I turned on my laptop and immediatelty I shut it down and It dind't restar, during the day while I was working, sometimes I turned it off and all seems ok, but this evening (after a workday and after backup) it restarted automatically again after shut down !

Cisco :: Associating Light Weight AP To Specific WLC5508

Feb 11, 2013

At the present, we have two WLCs (5508).  There are a total of 84 LAPs (1242AG).  One controller is configured as the master controller in which all our APs associate to.  It's currently running software version 7.0.116.0 and some of our BYODs using Windows 8 are unable to connect to the wireless.  The fix for this is to upgrade the software of the WLC so that the LAPs can obtain the update to solve this problem.  Simple!  However, before rolling this out into the production wireless network, I would like to test it out on our second WLC which has no LAP associations, a test WLAN configured, and a newer software image loaded (7.4.100.0).  I have a spare LAP that was previously associated with the master controller running the same software version (7.0.116.0).  What I'm looking to do is associate this LAP to the 2nd WLC instead of the master so that I can ensure that the LAP gets the newest software.  Then, I would like to test a Windows 8 device to make sure it connects.So far, I have done the following:
 
1. Disabled the 1st WLC from using Master Controller Mode and rebooted AP - result was unsuccessful; still associated to 1st WLC.

2. Reset LAP configuration excluding static IP info and reset AP - result was unsuccessful; still associated to 1st WLC.

3. Compared config for both WLC but since I'm new to these devices, I'm not sure what needs to be configured/changed.

Cisco Switching/Routing :: 5508 WLC And Nexus 7K - Clients Cannot Obtain IP Address Intermittently

Jan 22, 2013

I have a strange behavior between a WLC 5508 (version 7.0.116.0) and NEXUS7010.
 
WLC
The WLC is configured in DHCP Bridging Mode (it sends DHCP requests without change)
 
Nexus
The VLAN interface is configured as follows
 
interface Vlan501
  ip access-group acl-int-vlan501-in-1 in
  no ip redirects
  ip address 10.12.56.4/21
  ip ospf network broadcast
  ip router ospf 100 area 10.23.0.0
  hsrp 51
   
Clients can not obtain an IP address intermittently. If I deactivates the ACL when the problem appears(when the client can not obtain an IP@) the probleme is resolved
 
Note: Before the WLC was connected to Catalyst 6500 and worked properly for 2 years (with same configuration)
 
I saw this note about differences between DHCP relay on the NEXUS7000/NXOS an Ip helper one the 6500/IOS URL. Do you think the problem may come from the DHCP relay or ACL on the NEXUS.

Cisco AAA/Identity/Nac :: 5508 / ISE / BYOD / Windows Clients Reject ISE Local-certificate

Mar 26, 2013

We are deploying BYOD with Cisco ISE 1.1.2 and WLC (5508) using 802.1x authentication.Windows clients cannot connect to 802.1x SSID with the following error on ISE:Authentication failed : 12321 PEAP failed SSL/TLS handshake because the client rejected the ISE local-certificate
 
The client doesn't have preconfigured wifi profile or root certificate installed.The concept of BYOD suppose that you can connect your device without any installed certificates and preconfigured wifi-profiles.
 
The problem is that Windows 7 supplicant does not send TLS alert in pop up window, when connecting to 802.1x SSID.If this alert is seen, than you can accept it and proceed the connection. After that you will be asked to install ROOT-cert, get your own cert and etc.So, the question is: how to make the windows supplicant to show the pop-up window with TLS alert?

p.s. the attached file shows the example of pop up TLS-alert window
