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

Please post the same question on SMALL BUSINESS WIRELESS section of the Forum..

Cisco Access Points Rebooting

Has anyone experienced a Cisco Access Point reboot itself, on it's own?

7 out of 17 are rebooting... but it's not isolated to one IDF it's different spots within the building.i will check the log in flash.
Hmmmmm ... And if you do a "sh version" to everyone of them it comes up saying something like "by power-on"?
If this is the case, you may also want to consider the copper cables between your Injector and your AP.

My router and access point reboots when trying to stream content from iOS devices or mac to my apple tv.

the zycel N series access point and cisco router reboots when i try to stream or mirror onto apple tv using air play. What can be the cause of the problem?

Please answer as many of the following questions as you can. You may already have answered some of them. In that case, there's no need to repeat the answers.
Have you restarted your router and your broadband device (if they're separate) since you first noticed the problem? If not, do that now and see whether there's any change.
If your browser is Safari, then from the Safari menu bar, select
Safari ▹ Preferences... ▹ Privacy ▹ Remove All Website Data
and confirm. Any change?
If you're running OS X 10.9 or later, select the Advanced tab in the Preferences window and uncheck the box marked
Stop plug-ins to save power
Any change?
Quit and relaunch the browser. Any change?
Log out and log back in. Any change?
Enable Private Browsing in the Safari menu. Any change?
Are any other web browsers installed, and are they the same? What about other Internet applications, such as iTunes and the App Store?
If other browsers and Internet applications are also affected, follow these instructions and test. Any change?
If Parental Controls is active for any user, please turn it off and test. Any change?
If only Safari is affected, launch the Activity Monitor application and enter "web" (without the quotes) in the search box. If a process named "Safari Web Content" is shown in red or is using more than about 5% of a CPU, select it and force it to quit by clicking the X or Quit Process button in the toolbar of the window. There may be more than one such process. Any improvement?
Again, if only Safari is involved, open the iCloud preference pane and uncheck the box marked Safari, if it's checked. Any change?
Are there any other devices on the same network that can browse the Web, and are they affected?
If you can test Safari on another network, is it the same there?
If you connect to your router with Wi-Fi and you can also connect with Ethernet, do that and turn off Wi-Fi. Any difference?

WCS Access Point Reboot versus Cold Boot

I'm aware of the process an LWAP AP goes through when a cold boot is performed, specifically dealing with 1130 access points. I've noticed that when using the reboot command in WCS, the process is much shorter than a cold boot (unplugging the AP from power and network and then plugging everything back in).
So the question is - what is the difference between the reboot command in WCS and performing a cold boot? Does the AP retain some information during a reboot and therefore not require as much time to boot up?
Thanks for any help...

You can restart the access point by one of the following mehtods
1. Remove the power and replug the power cable
2. Using the CLI in the ap prompt type boot command. i.e [ap:boot]
3. In the Web interface use the System Configuration Setup page to restart the access point. Click Warm Restart System Now to perform a warm restart of the access point. A warm restart reboots the access point. Click Cold Restart System Now to perform a cold restart of the access point. A cold restart is the equivalent of removing and then reapplying power for the access point.

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

its a new one with default setting as per my knowledege its a controller based access point so pls help how to convert into standalone access point and which image is compatible with that.

Converting a Lightweight Access Point Back to Autonomous Mode
You can convert an access point from lightweight mode back to autonomous mode by loading a Cisco IOS Release that supports autonomous mode (Cisco IOS release 12.3(7)JA or earlier). If the access point is associated to a controller, you can use the controller to load the Cisco IOS release. If the access point is not associated to a controller, you can load the Cisco IOS release using TFTP.
Note In some LWAPP deployments, the LWAPP controller resides between the access points and the rest of the network. In this topology, all traffic must cross over the controller before communication with network resources, such as a TFTP server, can occur. When converting back to non-LWAPP IOS with an access point that is no longer using the LWAPP protocol, traffic does not cross over the controller to reach the TFTP server.
Note The lightweight 1300 series access points can only be converted back to autonomous mode using a wireless LAN controller.
Using a Wireless LAN Controller to Return to a Previous Release
Follow these steps to revert from LWAPP mode to autonomous mode using a wireless LAN controller:
Step 1 Log into the CLI on the controller to which the access point is associated.
Step 2 Enter this command:
config ap tftp-downgrade tftp-server-ip-address filename access-point-name

Hi Nassem,
It looks like you ended up with a Lightweight AP (LAP Part#) instead of an IOS AP. This can be fixed;

Downgraded A1240 Access point to IOS that support CLI command

I have a new A1240 and it IOS is working with new command LWAPP and need a control server to manage the access point. It (ios) does not have configure terminal command. I think I can delete the IOS in the flash and load a older version IOS. I went ahead and deleted the IOS and assumed the access point will go to rommon mode and allows me to archive a tar file (older ios) into the access point. However, I only get AP: prompt and stuck here. I can not run copy or archive command. What are recover process. Need your expert guidance. Au Ray Singapore

Hi Au Ray,
Have you tried this method?
Using the MODE button
You can use the MODE button on 1100 and 1200 series access points to reload the access point image file from an active Trivial File Transfer Protocol (TFTP) server on your network or on a PC connected to the access point Ethernet port.
This process resets all configuration settings to factory defaults, including passwords, WEP keys, the access point IP address, and SSIDs.
Follow these steps to reload the access point image file:
Step 1 The PC you intend to use must be configured with a static IP address in the range of 10.0.0.2 to 10.0.0.30.
Step 2 Make sure that the PC contains the access point image file (such as c1100-k9w7-tar.122-13.JA.tar for an 1100 series access point or c1200-k9w7-tar.122-13.JA.tar for a 1200 series access point) in the TFTP server folder and that the TFTP server is activated. For additional information, refer to the "Obtaining the Access Point Image File" and "Obtaining TFTP Server Software" sections.
Step 3 Rename the access point image file in the TFTP server folder to c1100-k9w7-tar.default for an 1100 series access point or c1200-k9w7-tar.default for a 1200 series access point.
Step 4 Connect the PC to the access point using a Category 5 (CAT5) Ethernet cable.
Step 5 Disconnect power (the power jack for external power or the Ethernet cable for in-line power) from the access point.
Step 6 Press and hold the MODE button while you reconnect power to the access point.
Step 7 Hold the MODE button until the status LED turns red (approximately 20 to 30 seconds), and release the MODE button.
Step 8 Wait until the access point reboots as indicated by all LEDs turning green followed by the Status LED blinking green.
Step 9 After the access point reboots, you must reconfigure the access point by using the Web-browser interface or the CLI.

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

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.
