Cisco :: WLC 5508 - Wireless Client Gets Random And Temp Invalid IP After Being Connected

Jun 24, 2011

I've got a setup like this:

WLC 5508 v7.0.98
6-7 Autonomous upgraded to lightweight APs - 2 * 1231G while the rest are 1242AG
3 dynamic interfaces, 2 to Corp (diff VLANs) and 1 to Guest
4 WLANs binded to different interfaces
2 to the Corp interface Vlan X
1 to Guest
1 to Corp Vlan Y

DHCP for Corp is provided by their own Win DHCP server while controller is the DHCP server for Guest. Lease time is 1 day.
 
My problem now is, some clients, at random, loses their IP after being connected to the network. They get a 169.254.x.x. They connect to the Corp network OK, no browsing issues but after a while, they lose their IP address.
 
They can either wait for a while before getting an IP back or just simple renew their IP on their machine.
 
I've tried increasing the threshold values in the Local EAP to double its default values and also setting the WLAN session time out values to infinite. However, these 2 didn't work. I'm still having clients that occasionally lose their IPs at random.
 
I've also noted that this affects clients with WZC wireless drivers and not others e.g. Intel Proset.

Cisco Wireless :: 5508 - Client Unable To Stay Connected

Jun 26, 2012

Background: Wireless credit card machines can't stay connected to the 5508 controller 7.0.116 / 1142 ap wireless system. MAC address of one of the wireless hosts is 00:12:0e:ec:ce:97. AP servicing them is d4:a0:2a:99:34:60. Hosts are able to connect to the network after a reboot and stay connected for random periods of time but then don't come back unless you manually reload them. I have 3 in total in the same room services by the same ap.

I have the output of debug client 00:12:0e:ec:ce:97. Output showed 802.1x 'timeoutEvt' Timer expired for station 00:12:0e:ec:ce:97 so I increased the value to 4000ms on the controller but am still having the issue.

Note that the output below is the state the client stays in after receiving the timeout (802.1x 'timeoutEvt') showing subsequent attampts. The only way to get them back on is a reload of the credit card machine.

one of our customers wants to update the firmware of a 5508 wlc, but always gets the following error message:
 
Error Message   %UPDATE-3-INV_FILE_SIGN: Error! Invalid image signature!. Image may be corrupt.
 
but the same image works fine on another 5508.the update was downloaded via a smartnet for the wlc, on which  the update works fine. does the customer has to download another image  for the second controller, or should the image work on both wlc?

Cisco Wireless :: 5508 / 1142n AP - Unjoin Dissociated Intermittently And Random?

Mar 28, 2013

We have several 5508 controller with 1142n access points  some access points unjointed from the controller and do not rejoin.  It is not always the same access point and it does not happen in any order we can find.  All access points may stayed joined for a couple days then one may disjoin, we can bounce the Poe port on the switch and the access point will reboot and rejoin.  When looking at the switch port it shows power and link connection to the ap but we can not ping the ap.  usually the ap led will be black or out.

Cisco :: WLC 5508 Password Invalid?

Jan 23, 2011

I did some testing in WLC in our company wireless network.However, after my 3 hours testing, I had tried to login WLC again by GUI and SSH. The admin username and password does not work any more. All Read only and Guest Account did not work as well.Is any one had this issue before? Is there a restriction for access to WCL per 3 hours or one day? By the way, I did not change any password.

I am using 2 anchor controllers 5508 as DHCP server. Anchor controller A is primary and anchor controller B is secondary. From time to time, client will complain "duplicate IP address error" when they try to connect guest wireless.First question: both anchor controller should have a recorder of IP address which is assigned to each PC, right?Second question: is there any way this type of issue can be avoided?

Cisco Wireless :: Client Roaming With 5508 Controller

May 27, 2013

I am having some troubles with client roaming on a 5508 controller running firmware 7.3.101.0. As soon as a client roams outside the range of an AP they lose data flow and do not seem to transition to another AP for about 1 minute.This is a small network with 6 x AIRCAP3502E-N-K9 AP's (running in H-REAP mode) on the same floor and clients are a mix of HP notebooks, Mac Books, iMacs, iPads and iPhones. There are several seperate SSID's setup and the problem occurs on all. All are WPA2/AES with either a PSK or 802.1X. Both 2.4GHz and 5GHz radios are enabled with auto power and channel selection.
 
I have tried changing the roaming settings from default and also playing with the AP power settings to no avail.Is this normal behaviour or is there something I can do to improve the reconnection speed?

Cisco Wireless :: 5508 Client Gateway Setup

Dec 1, 2012

I've just installed a standard Cisco wireless install (5508, 3502i, local and flexconnect setups) all working swimmingly.
 
The customer has asked for a new WLAN for a particular group of staff that will route to a different gateway than the general wireless staff.
 
The 5508 is connected to a older Avaya L3 switch that is the customers core swtich, but it isn't capable of PBR so it routes on desitnation only and its default route is not where I need the new WLAN traffic to route to. An ASA will be connected to the Avaya switch (which is the alternate gateway I need to get the new WLAN users to). So my question is probably routing 101, but if the ASA interface, the Avaya swtich and the WLAN interface all reside in the same VLAN, can I give the wireless clients the ASA as their gateway via DHCP and successfully get their traffic to the ASA?

Cisco Wireless :: 5508 WLC - Associate Client From AP If Idle For Certain Time

Sep 16, 2012

Is it possible to rename the default webauthentication URL from [URL] to something like [URL]. We are running on 7.0.98.0, is it possible to do http for web authentication and https for Mgmt access if we upgrade the controller software?
 
We configured our guest wireless with no layer 2 authetication so users can associate with an AP and get an ip adress but they can't go anywhere unless they have a valid username and password(web authentication) - does this affect the performance of an AP since there will be many people associated with each AP, is there any setting in the WLC to de associate a client from an AP  if its idle for certain time.

Cisco Wireless :: 5508 Max EAPOL-key M5 Retransmissions Exceeded For Client

Feb 21, 2012

I have had several complaints from around the firm where by mobile devices are being bumped off the PSK secured network (All other SSID networks are operating A-OK). Both Android and iPhone devices are being affected, the device will just loop until it reconnects, sometimes up to 20 minutes of trying to establish a connection. It will eventually connect so the key is not the issue.I've attached a debug of a device which fails to connect and then shortly after is successful.

Cisco Wireless :: Roaming With Broadcom Thin Client On 5508

Jun 3, 2013

Since two months they work full time with the new Dutch Electronic Patient Dossier.We installed 3 Cisco 5508 controllers, version 7.0.230.0 last year on a HP-switched network on a layer 2 mobility domain.Cisco 1041 AP are
 
The personnel works woth thin clients url... The one with the double antenna.This client has a Broadcom BCM943228HM4L 802.11 a.b.g.n (2x2) adapter.
 
On the client they have a connected RDP session to a server with the documents.Now they are walking from one patient to another patient. The problem they experience is a very late roaming. At the beginning of the corridor, the client will associate, but is going to roam at the end of the corridor. We installed 4 AP's on each corridor, so they signal is very well, maybe to well?
 
I disabled client loadbalancing and band select.The lowest data rates are also disabled. Mandatory begins at 12 Mbps. I can increase this to 18 Mbps.These clients work with PSK, with both methods (WPA-TKIP and WPA2-AES) enabled.We did this because of many old and new clients.
 
The customer tried to find out the problem with a smartphone, same issue. Very late roaming.I can upgrade the WLC to 7.0.240.0. The only problem I have is the WCS. When upgrading to 7.2 and higher I need to have NCS.

Cisco Wireless :: WLC 5508 - Client Don't Receives IP Through Mesh (1552E)

Jan 31, 2013

recently I installed  WLC 5508 en the central office and installed a network mesh in a remote office; central and remote office is connected with serial link as WAN, and I have dhcp server in the remote office for give ip address to all users and devices in the remote office. Additional I have 5 LAP1552 (mesh) and 2 LAP1260 in the remote office, all clients that connect to LAP1260(this don't belong to the mesh) receive ip address from dhcp server, but neither client that try to connect to the mesh (LAP1552) receive ip address from dhcp server. I don't have if I doing some thing bad. The range IP that receive the all ap's belong to the network of devices and the range ip for the users belong to network of users.

Cisco Wireless :: WLC 5508 Centrally Switched Client Errors

Aug 16, 2012

I am having trouble with a newly configured install.  Basically it seems that my centrally switched guest SSID is not functioning.  As you change AP groups, which should change the interface associated with the SSID and also the dhcp client address, the client is retaining the original dhcp address from whichever AP group they first associated with. 
 
I also have a locally switch WPA2 SSID at each location which is working fine.  Clients are able to change dhcp address correctly as they move between AP groups.  It just doesn't seem to be working on the guest network, which is odd because it was working earlier in the install.  It has only started having issues yesterday afternoon. 
 
The interface above is assigned to the guest SSID in one of the AP group.  I assume this has something to do with it but I've been over my DHCP assignments on the core switch, local switch, controller, and dhcp server and can find no issue with the configuration..
 
 I am not sure why as I am not using DOT1X at all.  The guest is a pass-thru and the WPA2 network is just WPA + WPA2 with TKIP and AES.  No DOT1X anywhere on the controller...

Cisco Wireless :: 5508 WLC Excessive Client Authentication Association Failure

Jan 29, 2013

I have been noticing in my trap logs that there are an excessive amount of Client Association/Authentication Failures. I cannot figure out why. I have a Cisco 5508 WLC with 81 AP's (1131ag, 1142abgn, 1262N) models. The wireless devices are on a Windows Domain and use 802.1x EAP authentication, authenticating the user and computer info with a RADIUS Server. I look at the logs and all it can tell me is Reason:Unspecified ReasonCode:1. I read that the Reason Code is due to "Client associated but no longer authorized" but to be honest I am not sure what that means.

Cisco Wireless :: 5508 - Setting Client Count Per WLAN And AP Radio

We use WLC 5508 with 7.4. We tried to set max allowed clients per AP radio to 30 through GUI. We have APs with 80 clients associeted though.
 
When entering config wlan max-associated-clients max-clients wlan-id we got 
 
"WLAN/Guest-Lan/remote-lan is enabled. disable to configure max associated clients."
 
GUI doesn't show that message, should it?  In GUI, Is it necesary to disable WLAN before too?

Cisco Wireless :: New 5508 WLC And 3602i Access Points / Client De-authentication

Jan 25, 2013

Installed a new 5508 WLC last week, and finished bringing 68 new 3602i access points online in our College Dorms. We are seeing a lot of "Client De-authenticated" errors "Reason: Unspecified Reason: Code 1. Years ago I asked about error code 1. The reply from Cisco was: "The programers put the code in. It basically means we don't know what the problem is."Got a call from one of the dorms stating that students were getting knocked off the network while going to sites. If a student is wired, network is solid.Walked the dorm in question and was getting full bars of signals at all times, and was able to stream a movie from my Ultraviolet account without any break or slowdown as I moved from access point to access point. So.. my device, an iPad, was fully mobile and did not experience any disconnects.Did observe one student using a MacBook Pro. This student was constantly loosing connection to the access point. Checked the controller for the MAC of the student's computer. I did find deauthentication errors. BUT... this student's error was the computer was receiving an IP address from the DHCP that was already in use. At the computer the error message was a timeout issue.I am just learning the ropes on the 5508. Have used 3 4404s for the past six years.

Cisco Wireless :: 5508 Client Stuck In DHCP Required State

Aug 31, 2011

User is connecting to 5508, running 7.0.116.0.  Previously worked on another AP.  TV (client) is set to use dhcp.  As other posts have mentioned, "DHCP Addr. Assignment" checkbox is not checked for this wlan, but I also switched it to Required for this wlan but it did not make any difference.  Seems to be a problem with just this client as many other clients are on this AP with no problems.
 
Users have to register their MAC to get on our wireless system, but there is no encyption or security enabled once the device has been registered.

Cisco Wireless :: 5508 - Client Authentication Fails For Wrong EAP-type

Cisco Wireless :: 5508 - Limit Data Rate For Specific Client

Sep 12, 2012

I would like to be able to allow a specific client to only associate at 6mbit/s -is this possible using the wlc controller 5508? Another option would be to limit a whole w lan ssid to 6mbit/s but i can't find a way to do that either.
 
Other w lan ssid's on the same access points/controller need full data rates, so i guess i can't use the RF-profiling for this.

Cisco Wireless :: 5508 Getting Nest Thermostats To Stay Connected On Network

Dec 12, 2012

any luck getting Nest thermostats to stay connected on a cisco wireless network.  We are running 5508s (ver 7.2.110.0) and the thermostats are connecting to a 3502.  The WLAN is a locally switched FlexConnect SSID.
 
According to nest there are two potential issues - NAT timeout and wireless networks that do not play nicely with devices that sleep for long periods of time.  I've configured static NAT translations for the Nests, so that shouldn't be an issue.  Nest says "Nest uses Wi-Fi 'Power Save Mode' to allow it to sleep and charge its  battery while remaining connected to the internet. Not all Wi-Fi  routers support this feature or implement it correctly.  When they don't, Nest will have difficulty sleeping and will restart  in an attempt to reset its network connection. This may happen  repeatedly if your Wi-Fi router is incompatible with the 'Power Save  Mode' feature."  I've tried increasing the DTIM timers to no avail.
