Cisco :: WLC4404 - Continuous Access Points Dropping Out Over Primary Controller
Oct 1, 2012
Continuous dropping out some of them Access Points registered on the Primary Controller . What is the reason for this. We have a problem the last 2 weeks. What are the causes of falling out controler Access Points. The problem does not appear from logs. 70 LWAPs registered over Primary Controller. All AP mode is Local.
Primary controller model: WLC4404 SW:7.0.116.0
Secondary Controller: WS-SVC-WISM-1-K9 SW:7.0.116.0
Tertiary Controller: WS-SVC-WISM-1-K9 SW:7.0.116.0

We have two Cisco Wireless Controller 4404 with the IOS Version 7.0.220.0 and a lot of access points (ca. 170). Now i wan't to reboot a group of Access points where i found over a filter..Or how can i reboot all the Access Points at the same time over the Controller Interface? Is it possible? I only found the option in the WebGui where i can reboot 1 Access Point at the same time with "hardware reset".

We have two wism2 controllers. We have our access points split on the two controllers. I need to move all of the access points on controller 1 to controller 2 so we can perform maintenance on one if our 6500s. Is there and easy way to force all of the access points off the controller without changing any access point configs? I was hoping I could make a change in the controller in such a way that it would not accept any access points. If I had an ap manager interface I think I could do it but that is long gone now.

How to disable dhcp proxy on controller and what is the impact of doing it in the middle? We tried once by giving 'config dhcp proxy disable' command but seeing virtual ip again.(likely it gets back to proxy mode). We also have ip helper address on the L3 interface. We have only external dhcp servers configured..

We have a Cisco 2500 WLC with 136 APs. Recently, we discovered eight APs that were not listed on the Wireless > Access Points > All AP list. These APs were once working and connected, but now they are no longer in the All AP list. I located one of these APs and found the green LED blinking. I power cycled the AP and it came back online with a solid green LED and was then registered on the All AP list. The All AP list will only show the connected APs. I would like to know if there is a method to show the APs that were once connected and are no longer registered so we can better identify when an AP is not working?

We have an MPLS (layer 3) network 4 offices and a Data center. We are planning to install about 10 Access Points(3600 series) per office and have a controller(5508 series) in the Data center.
Questions:
1- Is this design possible, in other words, just one controller centralizing all Access point traffic in one controller in the Data center?
2- We would like to accomplish this in two phases:
A- install access points without controller handling authentication thru Microsoft IAS servers (current configuration with 1200 series)
B- Deploy wireless Controller in Data center and start migrating orphan AP to Controllers one office at a time.

I have installed/setup a cisco 2504 wireless controller and 3 aironet 1142 access points using the basic config on a windows sbs 2008 domain, the problem is that the clients that are connected to the 2504 aint getting the there ip addr from the AD but from the wireless controller, and there cant reach the clients on wifi from the clients that are connected to lan, is there anyway that i cant change this so that a client on lan can see the client on wlan and vice versa.

We recently acquired a 4404 Cisco controller for our network and have been adding our 1200 and 1130 Access points to the controller.This was accomplished by upgrading the APs to LWAPP and then they would automatically be discovered by the controller and then join. Lately, new 1131 APs that have undergone the same process, are not joining the controller. They are discovered but then the close the connection. We are running a flat network so all devices are in the same subnet.Software Version of the controller 6.0.188.0. [code]

If the 2600 series access points are compatible with a 4404 controller running 7.0.235.3 code? I was looking for a compatibilty matrix for the AP to controller to code comparison but couldn't find one.

what i am trying to accomplish is to set up a domain for my home network. the domain is going to consist of 2 server boxes both running ubuntu 12.10 server edition and a client machine running windows XPone linux box will be my DC using samba and the other will host email, and apache2 web services.i dont know if you need all of this info but in my experience its best to be thorough.I registered a domain through godaddy.com and made it point to my home IP address. now what happens because all of my machines are behind a router is when i type in my URL it brings up the login request for the cicsco webinterface. what i would like to happen is that my router points traffic to the ip address on my home net work 192.168.1.XXX that is hosting the apache2 webserver.I would also like to connect the client(XP) machine to the domain controller but i keep getting an error that says that the domain does not exist. I have been through the samba settings and they are exactly the same as when i set them up for a mock PDC using "example.com" as a domain name

I just turned on 2 Wirelless LAN Controllers 5508 and I am getting this message on both of them:
Loading primary image (Image not found)
** Unable to read "linux.pri.img" from ide 0:2 **
Loading backup image (Image not found)
** Unable to read "linux.bak.img" from ide 0:2 **
And it is taking me to the BootMenu. I selected option 4 to Clear Configuration and the controller seems to restart the system but I still get the same error. I checked the LEDs status and Sys is Amber and Alarm is OFF which according to the documentation is a System Crash.

Our 5508 Wireless Controller will drop MAC addresses clean out of the system. Addresses that are in use everyday just disappear. It is not a limitation issue because we are adding iPads everyday. And it is not a daily occurance, but maybe once or twice a week. Everything has been updated and it is more of a hassle than anything, I am just trying to understand what is happening.

I am trying to find an effective way to extend the wireless signal across our home. I have tried various different solutions. Currently, I have an e4200 primary router that is cascaded with two additional e1500 routers that have been configured as access points. The Linksys support team hosted my computer and configured the devices. The e1500 routers are connected via ethernet wires running through the walls. And, this seems to be working well. Here's my question. The e1500 routers are configured with different SSID names, which Linksys advised was required to avoid conflicts in communications from the three router devices. Is there any way to configure this set up or something similar so that the entire wireless network has the same SSID and is seamless. In the current configuration, I have to specifically connect to the primary router or one of the two access points.

We have a small office and already have a firewall in place that uses content filtering. I am looking for a low cost wireless access point that I can place behind my firewall that will allow me to control access by a username and password list, not just the passkey.
Does this exist without having to go to an Aruba or Ruckus type enterprise WIFI product?

Here is my setup:
Netgear WNDR3700 - Main router, DHCP turned on
4x Netgear WNR2000 - Setup as Access Points (DHCP turned off), connected to main router via LAN ports
I only want the guest network to have internet access. I have the guest network enabled on the router and access points with the option to "Allow Guest network to access main network" disabled. My problem is that since the access points aren't hooked directly to my modem via the WAN port, the guest network broadcasted from the access points does not have internet access.I have read up on setting up a separate subnet for the guest network using DD-WRT but was curious if there was a way to get the desired result with the stock Netgear firmware.

I am looking being able to control one computer at 6 stations. Each station will contain a keyboard, monitor, and mouse.They do not all need to be able to control or access the computer all at once. I would use a reverse kvm switch but I am looking at distances of 200-500ft between the stations/cpu.My last resort was to buy some cheap dells or build some low end computers and set up remote desktop but we would really like just having the keyboard, mouse and monitor.

how to migrate from WLC4404 to WLC5508. I want to know your propositions.
I could replicate the configuration manually but there is a lot of confirugation menus and all. If both could be online and migrate the AP to the new one until there is none on the old one, it would be great.

I have some network devices that are connected to a 110v power source that goes through a 110v/5v power converter.The Access points keep going back to factory default settings and losing their configuration. I have the same access points installed in the same situation but on a different site that work fine.have changed both the configuration and firmware to be be identical to the working Access Points and still the others default.They do not do this at a specific time of day and out of the 6, they do this at random and not at the same time. Sometimes they will go 24 hours + without defaulting, sometimes they'll go just 4 hours.

I would like to know how to delete a connection from my network. When I connect to the Wii it automatically chooses the right connection. What I have noticed though is that there is a third connection for a printer that is not secured and I have no idea why it is there or has an option to connect to the internet.

i have 2x WLC4404 they are in the same mobilitygroup and worked since a long time. Three days ago, ill upgraded one of them from 6.0.199.4 to 6.0.202.0. I have nearly 90 APs (1231,1242, different models)
The upgrade was successfull and i moved the APs from WLCA (6.0.199.4) to WLCB (6.0.202.0) almost all APs worked fine without 6 of them. This 6 APs cannot ping the AP-Manager-Interface from WLCB. But they can Ping the Router in this vlan, WLCA-AP-Manager and all APs in this subnet. They only cant get to the AP-Manager-interface from WLCB. Ping to Managementinterface of WLCB is also ok. Management and AP Manager are in different subnets. All APs and the AP-Manager-Interfaces from WLCA+WLCB are in the same subnet.
Switchportconfig and routing are ok. ive resetet the APs to default, checked switchport config, resetet switchport, power down ap for a while. ive tried many things, but nothing worked.I ever only can ping AP-Manager from WLCA, but not WLCB (again same subnet, and about 80 other APs work fine)
If i install a new AP on the same switchport, it works fine, without any issues. when i than unplug the "newAP" from this switchport and again connect the "oldAP" it can ping WLCA+WLCB and anything is fine.
Now i have the next and bigger problem nearly 15 of the APs that worked fine after upgrading, for now 3days+. Now they cannot ping the WLCB-AP-Manager-int too. And they dont failover to the WLCA with (6.0.199.4), i can reboot but they ever try to connect to WLCB. But they know both controllers.I only can get them to WLCA via ssh: capwap ap primary-base WLCAsname WLCAsmanagementIP..why the APs dont fail over if they dont reach WLCBsAP-Managerinterface?why i cannot ping WLCBs AP-Mana-Int from some APs.

We have a Cisco ASA5505 here that provides DHCP and routing to all our devices in our network. We also have a few other switches and wireless access points connected directly to the back of the ASA5505.For the past year all the wireless network signals has been working fine however starting last month, none of the wireless access points (we have three WRT54G) would allow proper connection (dropping connection, slow internet).I thought this maybe all THREE wireless access points are toast/bricked. So i went out and bought brand new Netgear WN604 and even with the new WAP i'm having same connectivity issues (really slow internet).When hardwired directly to the switches we get BLAZING fast internet & connectivity, no issues.
I called CISCO TAC and they automatically said "our ASA5505 is fine, it has to be your wireless access points" not working properly. I explained to them that i also purchased two brand new access points and they are doing the samething now, how can that be?

I've had some long standing issues that I've tried various things to fix. I have two WAP4410N access points set up at a smaller sister company. Wireless clients (laptops) are not receiving DHCP assigned IP addresses. If I type in an IP manually, it works fine.The sister company has a point to point T-1 connection to our main building. Our main building has the DHCP server. The router on the sister company end is configured as the DHCP relay.
I've upgraded the firmware three different times in the past to hopefully resolve the issue, but no luck. Just today, on one of the WAP4410N's, I upgraded to the 2.0.6.1 firmware (backing up config, reset to factory default, upgraded firmware, reset factory default again, restored config). After the first reset to factory defaults, the Access Point itself picked up a DHCP address from the server, and I verified this in the DHCP console on the server, so I know that the DHCP relay is working. However, my laptop would not get a DHCP address when connecting wirelessly through that access point. It is a Windows 7 Enterprise laptop. I also could not get a DHCP IP with my iPhone connecting to wireless, to rule out specific issues with just a laptop.I have the DHCP lease times for the subnet that these WAP4410Ns are on set to 2 hours.
To put a cherry on top, there is one laptop that stays in a lab area at all times, connecting wirelessly, and it DOES get a DHCP IP address (I can see in the DHCP console that the lease for this laptop continually renews as needed). I do remember on initial config when I couldn't get it to work, that I did a manual set up, gained connection, then switched it to DHCP...but that doesn't work for any other laptop.Why would the access points get DHCP address, but not anything connecting to the Access Points?

We have the following connection based in the services provided by our local telephone company, the connection arrives to a router Cisco 800 series. From the router, i send it connection to a switch SRW2024 v1.2 (Business series) 24-Port 10/100/1000 Gigabit Switch with webview. That switch is useful to send connection via RJ45 for a few of PCs. Then, I send connection to a switch SRW2008P (Business series) 8-port 10/100/1000 Gigabits with vieweb and power over ethernet. The last switch, send the signal via RJ45 to seven WAP2000 (business series) Wireless-G AP with PoE.
That network is running fine, but I've some problems to cover some areas within the building and sometimes the signal is really poor. The cable RJ45 between the PoE switch and each AP is no longer than 50 meters and each one with antennes about 8 or 9 Db.
So, now I've the possibility to change the access point for a power devices.

Using WISM with 7.0.220 and 1240 and 3502 APs. Just found that some of our 3502 AP didn't enbale their clean air and CDP when installed. This only happened on a few new APs. But the area these APs where we seem to have had a few problems with PCs. The only PCs effected where Computer On Wheels (COWs), Dell 780 Desktop with a Cisco Wireless Card.
Using an interl wireless card and others in thes areas worked.Once I enabled the CDP and Clean Air, the COWs worked.My question is with the APs not having CDP enabled, could this affect the cisco wirelss card in the COWs?

BTW the halls are next to each other.The house and the 3 halls are in the vicinity however not attached together(i.e. wall to wall). The distance between the house and the first hall is approx 1 road width distance.ISP is Virgin and the internet was installed this year hence has the latest Virgin Home Hub.I am aware that i probably require 3 wireless access points (1 for each hall).The first wireless access point will need to be connected with a RJ-45 cable running from Home Hub. Can i connect the Wireless access points up together or do they all need to come from the ADSL hub?I am not sure what Wireless access points would be best and how to go about connecting this all up

I have New Pace 4111n Wireless Router that I got from AT&T and is setup on 1st floor, but its wireless range does not get me to 2nd floor. I also have the 2Wire wireless router from AT&T. In Addition, I have ethernet connection from level 1 to level 2 as well.
I was wondering if it is possible to have the Pace Wireless N router to work as modem and wireless access point, at the time use the 2Wire router to broadcast wireless and act as access point for 2nd floor.
IF its doable, how should the two be configured and connected.

I've recently bought another PC, but set it up in a different area than my existing computers. It's down in my basement, along with my PS3, Xbox 360, and Wii. Now the problem is connecting all of these "toys" to the internet. I only have one in-wall ethernet port, which my PC is currently plugged into. Leaving my PS3, Xbox, and Wii, only with an extremely weak wireless connection. Now, my original thought was just to buy a network "switch," BUT then I remembered I have an old D-Link router. So, logically I should be able to plug an ethernet into the wall, then into the WAD port on my router, then plug my Xbox, PS3, Wii, and PC into the 4 remaining LAN ports on my router. I want another WiFi access point using the same network, and a wired connection for all of my gadgets.

We have a WLC 4404 with about 85 1121 and 1241 APs. - I just added 6 new 3501E with Antennas, and configured the a new SSID, but non of my clients can connect to any of the 3501s. One solution from a tech was to update the NIC drivers. I verified that all test clients are 802.11N and sometimes they find the 3501 but often they switch to another of the older and weaker 1121 or 1241s. On one test I had a 3501 just outside his room and his client nic was picking up a weak signal 2 floors up, then it would go to one 1 floor down. eventually we could get it to feed of the nearest 3501 but it would go back to another 1121 or 1241 soon thereafter,.
