WLAN 4402 Access points hang or reboot

We are seeing a very strange issue in our WLAN setup. Our access points hang or reboot randomly. We have WLAN controller 4402 with 25 Cisco 1020 Access points. Our syslog server shows for some access points rebooted. While others just hang and then come back online after 10-15 minutes. We have similar code 3.2.78.0 running at other sites and everything seems to be stable, therefore we do not want to upgrade or install a new code. Any suggestions, or help will be highly appreciated by the experts.
Thank you
Ismail

The errors we saw were "[ERROR] spam_lrad.c 1840: AP 00:0b:85:66:77:88 associated. Last AP failure was due to Configuration changes, reason: did not get join response"
We called Cisco TAC, got the case escalated to the highest level possible, till we got hold of the actual developers of the code. Gave Cisco engineers the Sniffer packet information of the wlan controller and AP.
Finally Cisco engineer found a bug in the code 4.0.179.8 The bug will be fixed in the next release.
Thank you

Ismail

My Access Point Hanged :(

Hello.
How are you?
I have an access point Cisco with Model "WAP4410 N" and it is Frozen everyday and I must Reboot it. I updated Firmware too but my problem not Solved, How can I fix it?
Cheers.

Refer the below post
https://supportforums.cisco.com/discussion/10838856/disconnection-problem-wap4410n
Since you already have upgraded the Firmware and the issue is still there, you can have automated script to reboot the AP. Refer:

Can interference cause an access point to reboot?

I recently configured our WCS to send email notifications. Monitor > Alarms > Email Notification
I now receive emails from WCS stating that some access points dissassociate from the controller, and then another email stating they are back again. Not the same APs, not all at the same time, etc. We have 1200+ access points. A very small percentage... maybe one or two per day decide to leave the controller and then come back.
Looking at the controller, I see this is a true statement. I see that the access point's uptime is equivalent to the time is left the controller and came back again.
My question is... does anyone else have this configured, and if so, what was causing the access points to disassociate? I cannot tell if the access point is actually rebooting or simply wandering away from home.
Is there a way to see what caused the AP to leave and come back again? With nobody in the building at 7pm, I don't think it was human intervention. Other access points on the same switch, and they don't wander. I do wonder if interference or something else can cause an access point to reload.
The APs are AIR-LAP1210 on a 5508 running 7.0.98.0
Are there any known bugs that you are aware of?
Thanks in advance!

You are in luck. Like you we have 4500 radios and we turned on alerts and we got slammed on this as well. I will share with you some of the things that contriubuted to our problem. It just wasnt one issue...
1) We had 200 APs configured as a primary to 1 WLC. Well that WLC could only take 150. So when one AP jumped off there were 50 other aps interested in getting on. And when this happened we got an alert. We only fill 125 per wism today. This cut down on a good portion of our alerts
2) We disbaled ap fall back. Once the aps were where we wanted them we killde ap fall back. (no more bouceing around).
3) We had a few aps with link problems. Not many but a few. These aps would lose data connection but still keep power and not reboot. We either had to replace the patch cable or do a new run.
Take a few and investigate them. You will start to develop your own pattern.

WLC 5508 and remote site (DMVPN) Access Points

Hi All,
We just purchased a WLC 5508 and would like to know if it will control remote VPN site Access Points. Here are the details:
The 5508 will live at our home office. We have multiple remote sites that are connected via Cisco's DMVPN. Each site has one Cisco 1131 Access Point hanging off of either a Cisco 1841 or a 2811 that is using DMVPN back to the home office 2811. Can the 5508 manage the remote Access Points?
Thanks for your help guys!

Can someone post s40 v6 access point wml?

Hi,
i use a nokia c3-01. I cant use email on my nokia as in the commercials suggested because my provider needs proxy settings. For the standardinstalled Internetbrowser i can configure a alternative account but the standard email prog just support wlan or access point. and in the nokia s40 v6 menu there seems to be no possibilty to configure access points with proxy.
Does someone have a wml example for nokia s40 v6 to get access point for the email prog in nokia c3-01 with proxy?
I found a WML-Example for Nokia s40 v5 but the c3-01 does not acceppt and does not show the access point after senden the generated .prov file to the c3-01. If someone needs help how to convert a wml to .prov i can help if needed.
heres the access point with proxy wml example for s40 v5:

I added one access point in settings and my email is working now.
I've done below steps, you could try to modify to your internet access point.
Menu->Settings->Configuration->Personal config. sett.->Options->Add new->Access point Account name: VFNZ internet Access point settings: Data bearer: Packet data Bearer settings: Packet data acc. pt.: www.vodafone.net.nz others keep the default values. Then back to the personal accounts and activate the VFNZ internet from Options.
Ovi Store can be accessed normally.

Access Points Joining Random WLC

My environment contains 4 seperate controllers. 1 controller in the datacenter which remote offices use with HREAP and discover this WLC using DNS We will call this Controller WLC1. 2 more controllers (WLC 2 and WLC 3) in the corporate headquarters to support >40 access points in a N+1 configuration and finally an anchor controller which doesnt matter in this post.
What I am experiencing is Access points in the Corporate office are using DHCP option 43 to discover the WLC2. every night or after long periods of time a random number of my access points are either rebooting or most likely sleeping. Then are attaching them selves to WLC 1 which is in the datacenter and is not supporting DHCP from that location which to clients make the wireless network seem to be down.
I think that with using a hybrid of DHCP and DNS is partly my issue but it shouldnt be. I have primed all the Access point to look at primary controller WLC1 and secondary controller WLC2 both by name and using the IP address of the respective management ports.
Can there be any explaination for this and why this seems to be so random?
WLCs are 5508
Corporate Access points are 1142
***EDIT
After some more investigation this isnt completely random rebooting the access points in question are connected to a new 4506-E chassis with the Sup 6-E while the other access points are connected to a 6509-E.. not sure how much this matters but I am seeing in the access point logs that about every 2-3 hours they are accessing DHCP again and sometime not successfully. Is there some EnergyWise or power savings happening on the 4500 possibly??

I understand that all and here is a screen shot (see attached) of an ap that was on WLC 2 last night at midnight when i wrote this orginally and now how jumped to WLC 2.. The major issue here is that WLC 1 does not give out DHCP because it is used for HREAP and remote office that have other local DHCP servers.
I am running code 6.0.199.4
Now yes all controllers WLC1,2,and3 are in the same mobilty group. Maybe I should move the WLC1 out of the mobility group and that might solve the issue. Here is a log too. See timing is 3 hours and then its trying to find another controller. I see a retransmission count exceeded here. What can cause that? I have 4 port LAG configured on both WLC2 and WLC3 and they are both on seperate 6500 switches. This access point is on a seperate floor connected to a 4500 with uplink to each of the 6500's

WAP4410N Access point and 4404 WLAN Controller.

Hello to all,
I am planning to setup a new WLAN using WAP4410N Wireless N Access Point. Is it possible to manage the AP using 4404 WLAN controller ?
I need to buy arround 42 AP for covering the entire building.
Regards,
Aslam

leolaohoo
Could u please tell me which series can be used with 4404 WLANC ?
Also the AP Should support Bridging or Mesh.

Using n80 wlan on mixed mode n/g access point?

I have a d-link dgl-4500. I use it in mixed mode n/g. My computers can connect just fine.
If I want to get the n80 to connect, I have to first change the wireless channel to 11 and then change it to channel 1.
Then and only then will my n80 find the access point.
If I set my AP to G only, then the wlan fires right up.
I'm not an expert on wifi. Are there any advanced wifi settings I can change to help my n80 find the AP easier?
current settings:
2.4GHz mode
mixed n/g mode
2.412 CH. 1
auto transmission rate
20MHz channel width
visible SSID
beacon 100
RTS threshold 2346
fragmentation threshold 2346
DTIM 1
short GI yes
802.11b protection no
Those are my current settings.
Thanks for anyone who can help.

Aironet access-point 1231G reboots itself frequently...

Hi there,
We have one 1231G access-point which reboots itself after every certain time, its uptime has never crossed some 30 - 35 mins, usually it remains to 10 -15 mins. Some days ago, I saw a similar problem being discussed on thsi plateform but after the NetPro being changed, I could not find the progress on that thread. The guys in that thread suggested to physically separate the wireless controllers and then re-attach it back. Instead of doing this I tried physical reboot/power-cycle of thsi access-point. That access-point behaved normally for some days but after some that it aain posed the same problem. Kindly help me with probable solutions to it.
Thanks and regards,
Gaurav

This looks good to me, although let me know your thoughts on it.
One thing I have observed that the it showed a high CPU spike when it reboots and stops responding on the network. sho proc cpu his command, just after the reboot shows a spike of between 85 to 100% CPU utilisation. Any thoughts!

How can i add and configure a new AIR-LAP1142N-E-K9 Access Point to a AIR-WLC4402-12-K9 WLAN controller

How can i add and configure a new AIR-LAP1142N-E-K9 Access Point to a AIR-WLC4402-12-K9 WLAN controller

Thanks alot, that helped me .....
what about option 43..i am using one wlc and the switch where wlac and APs are connected is playing the role of dhcp server used by APs as there is a dhcp pool configured. please advise. will the command be
option 43 hex (f104xxxxxxxxxxxx) f104 adding to it the management ip address of the wlac in hexadecimal.
if the ip address is 192.168.10.5 then the command will be
option 43 hex f104c0a80a05
please correct me if i am wrong!!!!

T60 - WLAN regularly loses connection to access point

Hi,
my T60, Windows Vista with
ThinkPad 802.11a/b/g/n, 802.11b/g/n Wireless LAN Mini PCI Express Adapter
WLAN driver version 05 Nov 2007, v7.3.1.127
WPA authentification
regularly (i.e. once every 15 min) loses the connection to the access point for some seconds.
I already tried different access points, different encryption, different WLAN channels, but nothing helped.
So the cause seems to be the WLAN adapter of my T60 or the driver.
I am using the latest driver. As far as I remember, I did not experience this issue on Windows XP.
Does anyone have an idea how to solve this problem? It's quite annoying.
Thanks! Best regards,
Daniel

Hi lwoxen,We apologize about the inconveniences, but I would be glad to assist. One thing worth trying is changing the wireless channel on the Cisco WAP.To do this, just login to your U-verse gateway by going to http://192.168.1.254. From there you should see a list of all the devices connected, and you just want to choose the details on the Cisco AP. It should give you an IP Address. From there, type that IP address into your browser. It should ask you for a user name and password:User: ATTadminPass: 401!VENFrom there go to the wireless options and change the Control Channel option to one of the 4 channels. I would suggest trying 36.Let us know if that works. Also, I will be sending you a private message, so if you do have any further problems, you have a direct point of contact.

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.

Access Point Reboot

Hello Cisco experts,
I have an Access Point Cisco AP541N, working great, except that every 1 or 2 weeks, clients cannot connect anymore to it. I need to reboot it.
I recently updated the firmware to the latest version (AP541N-K9-2.0(0)), but that didn't help.
Is there a way on cisco access points to automate a daily reboot?
Thanks in advance for any help!
Cheers

Need Information For Connecting Access point to WLC 4402

Hi Friends
I need Some information for Connecting my New Access point ( Cisco AIRLAP 1242AG) with WLC(4402) Controller
In our network set up we have two WLC(4402) we needs to Connect this New Accesspoint To one of our WLC
My Access point is brand New. I need to Know what all i have to do inorder to connect this AP to the controller (from Acesspoint perspective & WLC perspective)
I need to Know what I need to do in AP to connect to the Controller
Do i need to Assign Static IP Address forAP or after connecting to the switch it automatically gets ip from DHCP and regsiter with controller??
Do i Need to Configure my AP with default gateway(the switch to which is connected ?) & DO i need to configure the AP with Controller Ip address ??
Pls Assist

Safwan

WLAN access point "missing" when connection alread...

Hello,
I have an E63 with version 400.21.013 firmware. However, I have experienced this problem from day one. I do not have a data plan but I use WLAN at various locations, and there is a list of access points in the Settings.
I have a home access point configured with WPA2 and I have all the settings saved in the Connection Manager (or is it WLAN Wizard - I don't know). When the phone is not connected to any AP and I use a program that wants data, it will almost always show the "Home" AP in the list which appears right after "Searching for available access points" is briefly displayed. "Home" shows up right below Search for WLAN. There is no problem making the first connection.
However, if the "Home" AP is already in use and I open another program that wants data, at times it will not show my Home AP in the list. If "Searching for available access points" is only displayed for a split second, "Home" will not be in the list. Sometimes I can close the program and open it again and if "Searching for available access points" stays on screen for about a second, then "Home" will be on the list and I can connect. Sometimes I will have to try 3, 4, 5 times, and sometimes it will never "see" the AP unless I disconnect the WLAN and start all over.
Right at this moment, there is no problem. I can open program after program and connect via my "Home" AP. But it is frustrating when it does happen. Has anyone seen this or found a remedy?
Thanks.

Have you tried changing the WLAN channel (i.e. frequency) of your home WLAN access point / router?
Try switching between few different channels (like 1, 3, 6, 9, 11) to see if some channel happens to work more reliably. It is possible that there is some radio interference (neighbouring WLAN networks, cordless phones, Bluetooth devices etc.) on the currently used WLAN channel, causing phone to discover this network less reliably.
In case your WLAN access point / router includes 802.11n support, make sure that your AP's "channel width" is set to a standard 20MHz mode (instead 20/40MHz).
This is a bit long shot suggestion (just guessing), but if switching the WLAN channel related setting on the AP doesn't help then you could also try editing your phone's access point (the one created for you home WLAN network, under Tools -> Settings -> Connection -> Access Points) so that your phone should consider this particular WLAN network as an "Hidden SSID" (even if network really isn't hidden) by changing the "Network status" setting from Public to Hidden.
