WCS displays Access Point as disassociated but WLC shows as associated

Hi all,
I have a WCS ver 7.0.172, a 5508 WLAN Controller with ver 7.0.116.0. At this WLC 21 Access Points (AIR-LAP1131AG-E-K9 ) were associated. As well I have one CleanAir Access Point (AIR-CAP3502E-E-K9) is associated.
And now ... my problem:
every time the WCS got a critical error and reports that the AP is disassociated from Controller. But if I take a look to the WLC the AP is associated and works at local mode and have two clients associated.
I cleared the alarm - a few minutes later the alarm will be reported again. Same result if I delete the alarm.
Could anybody give support for that issue.
Thanks and regards
Holger

Hi Holgerseiler,
Have you got any information/solution on this issue?
I also have same kind of issue. I have a WCS with version 7.0.172.0, and around 25 WLCs (version7.0.116.0, in which i checked) and totally around 1000 APs are assiociated in wireless network.
Some error messages are coming on my WCS device like
"AP disassociated from Controller [ip]"
Here AP name and WLC ip address will change randomly, but there is no impact on my network.
Thanks in advance
Sangeeth BS

Any ideas?

Fascinating just reading about your setup. I have a WRT350N and have noticed that it will drop its speed, sometimes down to 1Mbps. It seems to do so at about the same time every day, but usually comes back to speed in about 5 minutes. In my experience, the Apple TV will disconnect if the speed falls this low. Try monitoring the Linksys with Netstumbler, Vistumbler, or just in the Windows Network utility.
Check the "lease obtained" and "lease expired" times for your router to see if that is when the network fails. I've just finished reading an angry thread over at the Linksys forum about the WRT330N where someone mentioned that the router wasn't renewing its lease.
"I cannot set it run off automatic DHCP from the WRT330N, the router will not assign it an IP every time the lease expires, causing me to have to manually set an IP on the Print server. That's annoying. Having the router drop IP's to individual machines after 12-48 hours...very annoying."
http://forums.linksys.com/linksys/board/message?board.id=Wireless_Routers&thread .id=67412
If that is the problem, then I would consider setting up a Static IP address for your Apple TV. You can do that through the user interface -> Settings -> Network -> Configure ... (Quite intuitive as you only have change IP address and the subsequent details remain the same.)
My router assigns IP Addresses in the ranges of 192.168.1.100 ->149. The idea here is to choose an address outside of that range but is not greater than 192.168.1.253 (and should not end in the number 1). You shouldn't have to change the linksys router as long as 50 clients are assigned in that range. You'll have to figure that out by accessing your router webpage at browser address 192.168.1.1 -> the default password is "admin" (without the quotes).
Good luck.

3502 access point keeps disassociating

We have 5508 controllers on 7.0.230.0 code. We mostly have 3502 clean air access points. We have been having issues with certain AP's disassociating. You can go on the switch and reset the port and it will come right back online. Sometimes it will stay up for 5 hours some times just for 1 or less. The port it is on has no issues and I kept a monitor on the switch just to see if anything in particular was happening and saw nothing going on that would cause the AP to go down.
Apart from the AP being bad. Is there any kind of troublshooting I can do to see what could possibly be causing this. We also have WCS and the in the event log for these AP's it just has them as dissassociating and the reason being none.

Awesome.
Thanks for all of the responses.
Leolaohoo,
Here is my output. I am assumming this command is essentially the same as using a cable tester? If it is
F-1-C3750#test cable-diagnostics tdr int g2/0/7
TDR test started on interface Gi2/0/7
A TDR test can take a few seconds to run on an interface
Use 'show cable-diagnostics tdr' to read the TDR results.
F-1-C3750#sh cable-diagnostics tdr int g2/0/7
TDR test last run on: May 24 08:38:50

It doesnt appear to be testing too well. I ran the show command quite a few times and still got these same results. I did have to do a shut/no shut on the port to get the AP up and going. So when I ran the test the port was in a up/up status.
If we end up having to RMA that I guess that is what we will do. BUT, if there is any other way for a fix I would love to hear about it. We have a couple hundred of these, only about 10 ap's are experiencing this issue. But they are hanging in the ceiling and not easily accessible.

Limiting access points joining a specific WLC

Hello Cisco Forum Team!
I am currently installing a new WLC in a VLAN/IP segment that already has WLCs configured and access points registered. I do not want existing ap's on this VLAN to join this new WLC. Which is the best way to limit ap's joining this new WLC?
I am thinking of some sort of AP authorization list but by IP address instead of MAC address due to the high amount of ap's currently registred on the existing WLCs (approx. 300 ap's).
Thanks in advanced for your support!

AP authorization list would work but you have to use MAC address & cannot use IP address for that. Once you enable AP authorization you can add AP mac to the list like below using CLI.
(5508-1) >config auth-list add mic <AP1 mac>
(5508-1) >config auth-list add mic <AP2 mac>
(5508-1) >config auth-list add mic <APn mac>

Access points connect to wrong WLC

Hello everybody,
I have a problem with some access point.
We have two WLC's one AIR-CT5508-K9 and one AIR-WLC4404-100-K9.
now i have 6 access points that don't register anymore to the right controller.
in high availability i have set the right name of primary controller and also the correct ip address, but somehow they keep registering to the other controller.
Does someone know how i can fix this problem.
info:
AIR-CT5508:SEDA-PM_Line_1
WLC4404: SEDA-PM_Office_1
6 accesspoints are connected to SEDA-PM_Line_1 but they should be connected to SEDA-PM_Office_1
settings in AP are correct in my opinion

Access Point Secured Registration to WLC

Hello
Which option on WLC ensure that any AP registering to WLC should be first authenticated with a password and then register to a WLC

Hell there ...
Take a peek at the below link.. I think this is what you are asking ?
Lightweight Access Point (LAP) Authorization in a Cisco Unified Wireless Network Configuration Example
http://www.cisco.com/en/US/customer/products/ps6366/products_configuration_example09186a00808c7234.shtml

I want to use WRT160N as an access point...-but

I can't see other machines on network. I have a cable modem/router with 4 ports. Total of 3 computers (2 desktops wired to cable modem ,1 wireless laptop) Wireless laptop connects thru WRT160N to internet fine. I setup WEP, hid SID, and it still connects to the internet fine. For some reason I cannot connect to workgroup. I tried disabling DHCP server in WRT160N, but then my laptop doesn't get an IP address. For now all I want to do is use the WRT160N as an access point and be able to see local workgroup computers. I'm sure it's a simple setting I'm missing - but to be honest my brain has turned to applesauce and I can't seem to find anyone talking about this type of configuration anywhere. Thanks in advance, _mez

I am confused by your setup. You said that you have "2 desktops wired to cable modem".   So, is this how your system looks?
modem ------------- WRT160N ))))          (((( wireless computer
    |   |
    |   |--- wired computer 1
    |------  wired computer 2
If this is not correct, please explain more about your setup.
If this is correct, how is the WRT160N setup? Is the modem wired to the Internet port or a LAN port on the WRT160N? What address is the modem using?
What is the make and exact model number of your modem?   I assume the modem has a DHCP server -- is that correct?   Also, is there some reason that the wired computers cannot be connected to the WRT160N?

WRT54G ver. 6 Connected to access point and internet, but cannot access the web

I can connect to the access point and it shows that I an connected to the internet. However when I open a bowser it says page cannot be displayed! Signal is very good to excellent. Also, I have been using it all day and it was working fine, until I shutdown. When I booted back up it stopped working. The internet is working! I have XBOX Live working right now. Just not the computer. Any Help would be appreciated.

Hi... it seems that your Wireless adapter on does get a IP address or DNS no after reboot. Try assigning a Static IP address and DNS on the Wireless Adapter. Also try to update the drivers for that wireless adapter.

Access points no longer join WLC

Access point register on anchor wlc in DMZ

Hello,
I have an environment in which two WLC 4400 are connected to an anchor WLC 4400 in DMZ, This WLC in DMZ pass the Guest Wlan to other two WLC and terminate tunnel CAPWAP. The Ap in the remote sites, that are configure to register to WLCs in the remote sites, usually are registered on the two WLCs but sometimes they register to WLC in DMZ, how is possible if between WLC in DMZ and other WLC there is a firewall that block all the traffic except CAPWAP traffic?
If I reboot the APs they register on the two correct WLCs in remote sites.
Thanks

AP also uses CAPWAP. you should only allow capwap connection from internal controllers only on the fw.

Access Points at branch and WLC located at Head Quarters

Guys,
Please excuse these entry-level questions, but we are just starting here with Cisco wireless technologies.... Can we deploy, let's say 8 3600 APs in one branch and have the WLC deployed at another branch? Could this be possible?
thank you in advance

Guys, thank you very much for the input so far.
You are always not one, but many steps ahead from a novice
George Stefanick, yes, we have IPSec site-to-site tunnels with all the branches from the main site. Is via the vpn tunnels where FlexConnect limitations come to play? What exactly are the limitations of FlexConnect that I need to be aware of??/
As you can see, we have many branches all over the states and also overseas. The initial thought was only to deploy APs where we have warehouses (we really have over 20 branches - and growing - but only 5 of them have warehouses...) So, as I look deeper into cisco WiFi technologies, I can really see all these good features that we can certainly use. So with these features, I think it might make more sense, like rasikanayanajith advised, to really keep the WLC at the main site and deploy the APs at the warehouse with the FlexConnect feature.
This way, all the executives, as they travel to all the 5 warehouses, will only need to be concerned with one single set of credentials (their AD credentials), is this correct???? as I assume we can setup Radius Authentication for the clients to login via the WiFi.
please advise and thank you again

Access points not registering with WLC

Hi all,
I have a 5508 WLC in LAG mode and have 14 1231G WAPs connected to it already. However I still have to migrate 9 more WAPs from my old 4404 controller to the new 5508 controller. I cannot get remaining 9 WAPs to register with new WLC. I found following debug message from the WLC. My WLC license is valid for 50 APs. Have any of you guys seen this? What am I doing wrong here? Any lead is much appriciated.
I have LAG setup with 2 ports out of 8 ports. Don't understand why it's giving error of not having enough capacity.
Any advice is much appriciated. Thanks in advance.

Guess the SSC got corrupted..
Run the command "debug pm pki enable" on the WLC, copy the SSC and paste it on the WLC and see if that helps.. here is the link to do the same!!

Pictures do not display in my yahoo emails, but they show up if I go to forward the email, since I went to version 5.0 please help, win7

Since I updated to version 5.0 of firefox, 95% of pictures do not display in the body of emails using my yahoo account. If I go to forward the email however I can find them displayed in the forwarding window. I do have all pictures set to display in the ff settings, and have not made any setting changes before or after the update. At first I thought it was the "New" yahoo mail, which I switched to from the "classic", but I cannot switch back. I finally opened my yahoo mail in IE, and the pictures show right up.

L3 connections between Access points and WLC

hi,
we have a customer asking us to configure wireless system as per attached drawing.
WLC is in Data Center which is connected to Data Center Switch ( Cisco 3850), then this DC-Switch is connected to DC-Core ( Cisco Nexus-7K).
this Nexus-7K is connected to many campus Networks. in all campuses there is Cisco 4507 Campus Core which is connected to Nexus-7K.
then from Campus core many distribution switches are connected.
all Vlans for data and wifi is created in Distribution Switches. Distribution Switches are VTP Servers and many access switches with connected APs are connected back to this Distribution Switch.
All Access Points are registered at WLC in Data Center, but wifi clients are not getting ip address from DHCP Server, as well as even if we configured static ip address at wifi clients they are not able to communicate correctly.
please correct me if there is a mistake in this design , or we have a solution to solve this problem please let me know.
attached topology diagram
thanks,
anvar

Hey Anvar,
Too much details about network, to make it simple:
1- APs and WLC can be in separate VLANs (Not a problem)
2- As APs have joined, these two VLANs look fine for me
If your clients can't communicate probably with static IP address
1- From the WLC, ping default gateway for that VLAN
2- If the WLC can reach the gateway, its wired VLAN issue that you need to investigate in the path (maybe using wired device in the same VLAN as the clients in the switch where the APs are connected)
Now, about why the clients are not taking IP:
1- What is your DHCP, where its located? Is it the same one for all clients?
2- Do you have local APs or FlexConnect ?
3- When you run the debugs for DHCP where the process breaks?
Cheers,
Nour

3502 access point will not connect to 4400 Series WLAN controller

I recently upgraded our controllers to the latest version 7 software, as I read this was one of the requirements to get them to connect. But I am not having any luck getting into a controller. Normally I plug them in to the network, they pop into the controller listed as something like AP5057.a844.xxxx and then I can finish configuring them, but a static IP on them, etc...
This is the first of this model AP I have tried to deploy, so I am wondering what is different with these. or what I might be missing in the default config in the WLAN controllers.
Niether of which are set to "Master" either.
Thanks in advance, Tandrist

Hi,
The 3500 as you mention are supported on code 7.0
To get the access point to join the WLC we have different options.
If the access points will be on the same subnet as the WLC then you just need to get the APs to get a valid IP address from the DHCP server and once they have an IP address they will join the WLC because they are on the same subnet as the WLC.
If the access points are on a different subnet then the WLC you will need to have a DHCP server configured to give the unit an IP address and use option 43 or DNS so that the APs can send the join request to the correct WLC on a different subnet.
Or if not configure the AP via the console port with the static IP address and WLC IP address.
Also make sure that you have the correct country code enable on the WLC, and that the APs you purchased are the ones to work in this country, because if not the AP will not join the WLC.

WCS displays Access Point as disassociated but WLC shows as associated
