Cisco Wireless :: 3502i Cannot Join 5508
Sep 25, 2012
I have a 3502i(AP_1) that will not join a 5508 WLC(WLC_1)(code 7.2.103). The 3502i(AP_1) will join 4402 WLC(WLC_2)(Code 7.0.230). I have another 3502i(AP_2) that will join the WLC_1 & WLC_2. I am using capwap discover through DNS and hard coding the primiary WLC to AP_1 & AP_2. When I debug capwap events and errors, I see the static capwap messages and replies. Both of the WLC are on the same subnet. I have defauted the AP_1 and it joins the CISCO-CAPWAP-CONTROLLER as expected. When I change the Primiary WLC to WLC_1 it goes back to the CISCO-CAPWAP-CONTROLLER. If i change the primiary WLC to WLC_2 it joins. If I change the primiary back to WLC_1 it joins WLC_2 even though it is not a secondary. I know the previous joined WLC are stored in NVRAM, so that might be why it is doing that. I can join other ap to WLC_1 just not this one.

When we were installing some new APs, were plugged in to ports that were not configured on the WLC management VLAN.
This is the illustration
WLC management VLAN is VLAN 80 Management VLAN of infrastructure (Switches routers) is VLAN 10
The APs were plugged in to VLAN 10 and they were not able to associate themselves with the controllers.
Through research, those APs were getting a wrong IP address,
I did the Mode button, pressed for 30 secs, but this did not fix the problem, i thought it was going to clean the flash and bring the AP back to factory default I do not believe this happened.
We also added the cisco-capwap-controller.localdomain to our DNS servers, and then I rebotted the APs and still no luck.
What fixed the issue is we had to go to the DHCP server, release the IP addresses and we found those based on the macs of the APs. What is we do not have the mac addresses?
Now that I have the DNS entry created, if I plug in an AP on the wrong VLAN port will I be able to see it?

I've got several 3502i's that refuse to join to the controller, and just get stuck in a cycling blinking colors on the LED. Other AP's off the same port, controller, work fine. Logs are as follows...

This problem only seems to affect one of our sites. Every once in a while, several APs would lose link to the 5508 and get stranded. The only way to fix the issue is either to power cycle, or better yet SSH into the APs and use the command "capwap ap controller ip address x.x.x.x", and then they'd automatically rejoin the controller. At first, I thought network hiccups caused the APs to lose connectivity, but there's none that I could find. I have the primary/secondary controller IPs configured in them as well. See log below:
[previous log entries show AP working as intended, then...]

Devices Used;
WLC = 5508
AP - 3502I
Windows Clients = Windows 7
We are using WP2/AES for encryption and 802.1x for key management for our WLAN. The question I have is, when I look at one of the client's properties through the WLC 5508, then look at the "AP properties", its says that its using; Authentication = Open System, and WEP state = wep enabled. Why would the AP properties have open system and wep enabled when the WLAN is setup for WP2/AES??? There is also a "Security Information" Section just below the "AP properties" section and this lists the correct settings. Are the "AP Properties" irrelevant in this case?

A customer runs a 5508 WLC for quit a while. several dozens AP's are spread all over Europe an run just fine. All the AP's have a VPN based connection over an MPLS service provider, so we are using 10.x.x.x addresses only. We have upgraded to release 7.2.111.3 to support OEAP 600 and we have configured NAT in the Firewall as well a policy to support the home office AP. Everything works fine until the switch where the WLC was attached to crushed. From this moment on, all internal AP's ar no longer able to register at the WLC. A log at the console port on an AP shows that it tries to access the external (NAT) IP address. We had to remove the NAT flag to support the internal AP's.

I have a facility, where all the access points almost 250 of them are connected to two WisM's (One in each core switch ) . They are running in 6.0.199 firmware . These two WisM's are managed by WCS , which is running 6.0.188.
As i need to add more access points and to make fully redundant , 5500 controller was ordered and it has with firmware 7.0 installed. Couple of queries related with it .
1. Can 5500 be added in the WLC group, so that existing Access Points can be configured to use primary controller as 5500 and secondary / tertiary controller as WISM ?
2. Will 5500 be able to be detected by WCS , as the version of 5500 is 7.0 and WCS version is 6.0.188 ?
3. As WCS was already deployed and live, is it possible to upgrade, if the client has support contract like SUSA ?

My APs 1142N don't join their WLC. APs and WLC management interface are in the same vlan (WLC can ping all the APs). It is strange because it doesn't seem like they are trying to contact the WLC. What's strange is that I have other AP 1142N which joined this WLC without any problem.

I have a WLC 5508, AIR-LAP1142N APs and a SSID for students to connect to who bring their own device. I am still testing this and it has not been rolled out but I am running into some serious issues with joining the network. I am authenticating them through a RADIUS server (2008 R2). Problem: many of them cannot connect because they are lacking the certificate.
1. What is a good setup for authentication in a BYOD environment
2. If my setup is good what can I do to allow kids to use their computers on the wireless either without the certificate (which I know is unlikely) or what do I need to have them do to connect. I am hoping it does not involve hard wiring and getting the certificate from the server.

I am in the process of deploying 3502i APs. This site has 2 - 5508 WLCs both running Software version 7.0.220.0 and 2 - 4402 WLCs both running the same version of software as the 5508s. All of the APs that I have installed so far have joined the controller and I can associate to them and access the network. When the APs first are connected to the switch they go through the 'normal' boot up with the LED changing colors - white, red, green, blue (not necessarily in that order). Once the AP has completed its boot sequence the LED goes out and remains NOT lit.
This is happening to most but not all of the APs. This is the first time I have deployed 3502s - previous experience is with 1142s and 1242s and the LED does not do this with them.
I can, through the CLI, turn the LED on but it is then ALWAYS blue, even if a device is NOT associated to it.
I do not want to leave them off because the account will believe they have a 'dead' AP and with them always blue they cannot properly troubleshoot using the LED.

I have a customer with several older Aironet 1121G WAP's. In one area of the plant the noise levels from several large motors is preventing reliable connection to the WAP, even though it is located in the same conference room as the users. I am suggesting upgrading the 1121G to the 3502I to take advantage of the Clean Air technology. This raises two questions:
1) Will a single 3502I be able to effectively handle the RF noise, or does it require a network of WAPs to function properly?
2) Does the 3502I require the CT2504 controller for the Clean Air to work, or will it function in a stand alone mode?

how to convert a 3502 access point from Autonomous to Lightweight ? 3502 has a new IOS released back in Dec 2012 to work as staandalone mode. I need to convert this back to Lightweight mode.
I have been searching on web but have had no luck so far with anything. Tried converting it to lightweight in the same way as putting it on Autonomous IOS but errored out.

I am having a Wism on 6500 chassis with software code 7.2.103.0 Now......... I use to have 7.2.111.3 on the Wism before but for some reason I had to downgrade the code to an older version (some compatibility issues with the NCS)......
Now before all the APs were having 7.2.111.3 version running as soon as I downgraded the controller IOS most of them downgraded the code but a few still did not show up...... so I picked one of them and did a factory reset on the AP and was guessing that it might get the new code from the controller this way but unfortunately since than I have tried a lot of things but no luck. I have switches configured on layer 3..... other APs connected to this switch are working fine,........ when I reset the AP to factory default it doesnot take an IP obviously so I manually define the IP,,, you would find that configuration below too.... but than after a while it trys to locate the controller and could not find it.... where as, as i said other APs on teh same switch works fine......
the only thing i notice is that it does not release the IOS .. it is still having 7.2.111.3.....

I have a WLC2106 and AP3502i. The issue that I am having is the radio for 5GHz is not showing up in "Wireless > 802.11a/n" (see attached screenshot) I am not exactly sure what was the problem. When I went to 802.11b/g/n I do see an entry for 2.4Ghz radio, but nothing on 5GHz.
I have the AP plugged directly to my 3550POE, and when I used the command "show power inline" it says that the switch is providing 15.4W and there is still 345W remaining on the switch. The LED on the AP is solid green. I issued a no shutdown on dot11radio1 and the status is up/up, but there is still no entry under "Wireless > 802.11a/n"

I've got a number of 3502i's that I need to mount in a new classroom that does not have any ceiling (except the floor decking above). Ceiling is roughly 30-50' up. Contractors are going to run several 2" (or whatever we want) metal pipes from the ceiling down to a more reasonable level to mount the access points on and get below the hvac ducts/etc in the ceiling.
Problem is I can't find any bracket or mounting options for this! What are others using in this situation for mounting one of these access points onto a metal pipe such as this? I've checked Oberon Wireless, Terrawave and I don't see anything glancing through the product catalogs. Anyone mounting access points this way?

Recently I upgraded the wireless infrastructure in my campus and deployed WISM2 controllers and Cisco 3502i APs throughout the campus. Until now all my users were using 802.11b/g/a speeds without any issues. However, now I am trying to enable 802.11n speeds in a test group of users by enabling AES encryption and I am seeing lot of issues. These test users sporadically loose wifi connection and an asterix appears in the WIFI icon in the task bar. Interesting part is that all the manually configured wireless networks in the laptop stop displaying. The broadcasted SSIDs continue to show up though. All these users are using "Intel(R) Centrino(R) Advanced-N 6200 AGN" wireless cards with driver version 13.3.0.24. I had upgraded one of the client drivers to the latest 15.1 version. However, he still complained about wireless disconnection (I am not sure about this problem as I didnt personally attend his laptop to know the cause of diconnect).
One another interesting incident is that 2 people from this test group were having a meeting in a conference room once and surprisingly both dropped at the same time with the same symptoms. The only fix was to reboot their PCs.
I have done following changes in my controllers hoping that the problem would get fixed, But still no luck.
1. Enabled client band select.
2. Checked EDRRM for A as well as B/G
3. Changed Channel allocation from freeze to auto.
4. Enabled "avoid persistent interferers".
In my calls with Cisco support we also ran debugs in the controller and sniffer captures in the client machine. All we see in the controller is that the client dropped without any reasons. Also, didnt find anything significant in the sniffer captures. At this point not sure what to do. If upgrading the client driver is an option, then I need to produce some proof or document to the management which says the current 13.3.0.24 has known bugs to run 802.11n speeds. Scanned the entire internet, put a post in intel support site but no luck.
