Cisco Wireless :: WLC4402 Drops Network Connection
Dec 6, 2012
We have 2 AIR-WLC4402-K9 devices at a remote location that will both drop their network connections some undetermined time after a reboot. We cannot reach them via telnet, SSH or HTTP. In fact, we cannot even ping them once they drop connection. The only cure we've found so far is to power-cycle the controllers. The controllers are in separate rooms and connected to separate switches. We've confirmed the links are configured as trunks and have the correct speed/duplex settings. I tried updating the IOS & boot loader on one of them but that had no effect on the problem.

Have a MacBook and using Firefox. All lights on the router and modem are green. Does the same thing no matter what distance laptop is from router/modem. Seems to do it in 2-3 minute intervals.

I got my wife a new laptop in October, and it runs on windows 7, since the 25th of december she has been having connectivity issues with her wireless card. She had 2 bars on her signal strength, and I wanted to take the signal strenght out of the equation, so I got a N range booster to put in the room she is usually in, she now has a signal strength of 5 bars. However she still loses connection to the internet.
ISP is Bell Fibe 25 Router is the bell modem/router in one. My son's Laptop goes in that room, and has no issues. I have made sure the drivers are up to date on both the router/modem, and on the laptop itself. The only thing I cna think of is that it is the card itself that is faulty.

I'm fairly new to setting up hardware. I have WRT54G2 router and drops internet connection with ATT DSL. When I go to repair the connection, the wireless connection disappears and I have to reboot the computer several times to get the connection to reappear. [code]

We are using WLC4402 for our Aironet 1240AG access points. The clients are connecting to the access points and are authenticating to the RADIUS server. I am seeing the logs in Server 2008 but they are being rejected due to Network Policy on the NPS server.
Where do I see the Authentication Type on the WLC4400 or the 1240's? In order for the clients (authenticated via Active Directory user) I have to set the Authentication in the NPS Connection Request Policy to "Allow clients to connect without negotiating an authentication method".
I do not have a certificate on the server and my method options are MS-CHAP-v2, MS-CHAP, CHAP, PAP, SPAP, and allow without negotiating. This RADIUS server was moved from Server 2003 IAS to Server 2008 NPS and there were no issues in Server 2003 IAS. I have all authentication methods allowed and it still gives me the error below. Only when I check "Allow clients to connect without negotiating an authentication method" it allows the authentication to proceed.
Client Machine:
Security ID: NULL SID Account Name: Fully Qualified Account Name: OS-Version:
Called Station Identifier: 00-17-a2-87-54-00: SSID NAME
Calling Station Identifier: 00-41-96-b6-e3-27
NAS:
NAS IPv4 Address: 192.168.90.24
NAS IPv6 Address: -
[code]...
Reason: The user attempted to use an authentication method that is not enabled on the matching network policy.

2 days ago my e1000 died, so I went big and bought the e4200 (due to newness, its already loaded with Firmware 1.0.03 build 14) to aleviate my networking woes. I'm running into an issue where I'm utilizing both the 2.4Ghz bands and the 5Ghz band. My desktop as an AE1000, and I'm utilizing that on the 5Ghz band. Everything else in the house (Dell laptop, 2x iPhone 4 and an HP printer) are all connecting to the network wirelessly.
I have had 0 network issues with regards to my wired connections, or my 5Ghz connection. But my 2.4Ghz connection will continuously be unavailable. I have both bands set to brodcast, they have different names so my AE1000 can connect via 5Ghz band. Both yesterday evening, and this morning, my phones, laptop and printer cannot connect, and for the most part, the network doesn't show up on available networks. When it does show up, the devices can't connect.I'm proficient enough to do the general home networking, but I'm at a loss as to how to fix this, without a daily reboot of the router (which seems excessive and unwarranted for a 2 day old e4200 [or any router to be honest]).

I've tried two different brands of wireless network adapter now: a Netgear and a Belkin. They've both had the same issue.I'm running Windows 7, and the network connection will just randomly drop out. If I unplug and plug in the adapter, the network will reappear and it will connect to the internet just fine, until the next time it drops out.

My second computer on my network randomly drops out all the time. I have a WRT54G router that is working fine with my first computer (Windows 7) but the second computer (Windows XP) is having issues. It'll be running completely fine and you can even get on the internet after it's been on for a few hours but after a few minutes on the internet (10min about) it drops out completely and can't reconnect.

I have a PC upstairs, let's call it (Peter-PC), my dad has a PC downstairs (Kris-PC) and I just setup a linux home server downstairs as well called (server).Now, Peter-PC is connected through Linksys powerline adapters to the router, and server and Kris-PC are connected directly to the router as well.Peter-PC stays constantly connected to the internet, only until Kris-PC is turned on, then Peter-PC connection goes mental and begins to disconnect, reconnect, can't ping the router. As soon as Kris-PC is turned off,Peter-PC is back to normal.However, if Kris-PC and server are both on, they both operate fine. Seems like Peter-PC is the only unfortunate one.I mean the powerline adapters have been working for over 3 years now, and the Powerline light is flashing meaning they are communicating, I highly doubt it's the adapters.

no matter what device is used to connect to our Linksys WRY54G v2.0 Router, whether it be CAT6, internal wireless card (Intel Wireless LAN (802.11a/b/g/n), or USB wireless card (Linksys AE1000), she drops connections at random and frequent times and has to disconnect the device and reconnect to get internet back. She is still connected to the network though. The issue has been becoming more and more frequent the past few days and has been ongoing for a few months. We are at wits end with the issue. I looked on Linksys' website for updated firmware for the router AND the AE1000, no new firmware and same driver that is installed for the AE1000. We have tried to enable Multimedia Environment, Disable 802.11, unchecked "Automatically turn off device to save power", changed router channels from 6 to 1, have uninstalled ALL third party firewalls and AV/Spyware/Malware/Adware removal programs (but not before scanning the system), and lastly tried the DHCP Braodcast Flag Fix.

my laptop, which connects fine to all other wireless networks, has trouble on this one. It can browse the web all day, but the second a large file begins to transfer (video, a file download, etc.) it will drop the connection randomly, usually rather quickly. The computer does not need to be restarted to reconnect, it often reconnects on its own near-immediately, though sometimes I have to go to the system tray and reconnect manually.I thought it was too far from the router, but my tower in the same room connects flawlessly, and going in to the same room as the router doesn't work. This same laptop has been fine on every other network, and every other computer is fine on this network. I've web crawled off and on about this for months, but no one's problem is limited to one computer/network combination.

Often my router drops connection to all my devices. Multiple times a day. It's only for a minute or so, but it's annoying. I'm using a Linksys Wireless-N router (WRT160N) with WEP encryption. I'm running two Windows 7 laptops, LG BluRay player, Apple TV, Xbox 360 (Wired) iPhone 4, and a iPad 2. It doesn't matter if I'm browsing the web, watching Netflix, or playing a game, the connection gets lost. As we speak it happened again. I have no clue on what to do. I've reconfigured it multiple times. Firmware has been updated months ago.

I have had my DIR 615 router for about 6 months, and have had no problems. I have a notebook (Sony Vaio) and I also have a Blue-Ray Player and my DirecTV DVR connected by ethernet. Starting a few days ago I was having connectivity issues. At first I could see the network on my Vaio, but the Internet kept coming and going.I did some troubleshooting on the adapter and that seemed to work. Now I am having an issue where every 2 hours or so the wireless drops and the network disappears from the list of available connections on my notebook. I have had my netbook on (connected wireless) and the issues are replicated on that system.
Both of my wired devices do not see any interruption in connectivity. Living in an apartment complex I suspected interference and indeed there are a ton of other networks in range (as per inSSIDer 2.0). As there is no channel that is clearly open, I have set my router to auto channel scan. I also have tried some of the steps outlined in other threads. The thing I am noticing is that when the network connection drops my network (which has a unique name) doesn't even show up on inSSIDer, it just disappears. When working, my network is consistantly in the -25 range on inSIDDer.I should point out also that my notebook is a mere 8 feet from the router, and there are no obstructions.

info regarding my LAP521 access points that are refusing to join the WLC4402-12.This is my first lightweight access point implementation and I have 3 LAP521's and 1 AIR-CAP3502I-E-K9 access points on my network.They are meant to pick up ip address from external dhcp server and then join the WLC but only the 3502i joins successfuly while the 521's get dhcp address but do not join the WLC. From the logs, I can see that the WLC is discovered by the 521's and even get a response message from the controller but they are still unable to join as shown in the screenshot below.My WLC is running software version 7.0.230.0 and the 521's are running an lwapp image version 4.2.61.8.

We have a 4410N that all the time drops the connetion. We have approx 25-30 users using wireless. But when they try to connect or are connected, the router drops the connection like a yo-yo. The firmware is updated with no difference.
The wireless connection is very unstable. It's configured with WPA2 Personal and is connected through a POE-switch with IPv4. The logs don't answer the questions why it drops the connection.

I have a Cisco 4402 WLC running version 4.2.112.0 controlling 20+ AIR-LAP1242AG-E-K9 access points running IOS 12.4 (10b). I'm trying to setup an additional AP as MESH. When I try to change the mode from local to bridge, on what will be the rootAP, I get a message stating that bridging is not support on this unit.

I have one WLC 4402 & arround 29 Access point (1130) in our enterprise network. Wireless users LAN segment is diffrent from wired users.Wireless users like Laptop users, Mobile users & ipad users which are connetced with this wireless & using enterprise network.
Presently we are using WEP mode for security key. This WEP key are week & can be cracked easily. so security point of view i want to put strong encription mode.Presently i do not have any radius server.I found there are some modes are available Like WPA, WPA2 with PSK etc.
will there any problem with wireless users to access application after changing the mode? Which mode will be stronger & could not be crack. Could we achieve without radius server or not?

Our costumers has implemented 2 AIR-WLC4402-50-K9 with Software Release 7.0.98.0, the wireless infrastructure consist in 2 Root-Mesh-LAP and 8 Mesh connect over-the-air to deploy outdoor coverage.
All the LAP are Aironet 1520 Series Mesh Access Points with equipped with 3 antennas for 2.4GHz and 1 antenna for 5GHz (backhaul).For one year all seems to be ok, yesterday after a power outage of one Mesh-Root-LAP, 5 Mesh-Lap continues reload each 10-12 minutes, on the WLC Log you can see event like a reboot from AP Console, on the LAP console i can capture this event before the reload:

What does it mean? That the beacon signal trasmitted from Root-Mesh-LAP cannot reach the Mesh-Lap and so the Mesh-LAP force a reload?Where we should search the cause? In the power instability or in a interference on the 5GHz radio interface?

I am using a desktop computer and have the router downstairs so I am using a wireless usb to connect to the internet. My router is a Linksys E1000 and the wireless adapter is a Netgear WG111v2. The problem is Every few mins I drop connection for may 5-30 secs and then the internet is fine. During that time it does not say I only have local connection or anything like that it constantly says I have internet connection even when I dont. It is very noticable when i am playing an online game on my computer. I will get a few mins in and then it will drop kicking me out of the game and by the time I get kicked out my Internet is reconnected and I can join again.

I recently bought a new HP Pavilion dv6 Notebook PC and have been experiencing problems when connecting to my personal wireless network. It seems that whenever I'm downloading anything or using the connection extensively I'll lose internet connection and the wireless icon in the bottom right hand corner of the screen will show an orange star to indicate that connections are available. However if I go to available networks I can immediately reconnect to the network I was on.
I have other notebooks that run on XP that do not have this issue and use the connection without a problem. Also when I connect my notebook directly to my belkin router via Ethernet cable the connection has issues. I'm running my computer on Windows 7 Home Premium 64-bit and my Wireless adapter is an Atheros AR9285 802.11b/g/n Wifi adapter which appears to have up to date drivers.

my question regards to a pair of WLC 4402 with 7.0.98.0 software.Actual, our security policy does not really allow any peer-to-peer communication in a wireless LAN. Therefore we set the 'P2P Blocking Action' to drop, and the 'Broadcast Forwarding' feature to disabled (default).But now there is a special requirement for two mobile endpoints to communicate with each other, because one device controls the other.To test the communication, we first disabled P2P Blocking (without success) and further enabled Broadcast Forwarding to bring the communication up. Now it works, but the configuration disagrees with our policy.
1. Is there an alternative configuration as described possible, so that we do not violate the security policy? To allow only p2p connection between the two devices, ist should also be possible to drop any else by an ACL. But how to fix the problem with the broadcast, because of the needed ARP? My idea was to use a static ARP entry, but as far as i know, one of the both devices is not able for it.
2. Because, I did not find any detailed documentation:
2a. with enabled Broadcast Forwarding, the controller forwards all broadcast for any configured SSID, right?
2b. is the broadcast limited to the source VLAN/SSID?
2c. is the broadcast limited to an AP, to an WLC, or is it broadcasted to every AP on every WLC that has the relevant SSID?
we already have two new 5508 but not in an operational state now, because we plan to implement new 3600 APs.Do these WLCs offer more/another circumstances or possibilities?

One day when I tried to reset the system I had a lot of errors (see attach) and could not go on. After changing the image the following output appeared: "RAM Disk Image Integrity Check Failed (Bad Magic Number) Hanging". Now I have no response from the controller.

I am trying to track down a problem I am having with one laptop. Other wireless devices on the network are not showing the same problem. Connecting to the router by ethernet resolves the problem.Over a 120 second period, the wireless connection drops and reconnects several times. Each time it drops it almost immediately picks up and re-connects. The "down time" is usually between 5 and 20 seconds.I have updated the driver for the wireless card (it was out of date) but this did not resolve.
Reading posts here - I see you typically need to see a WiFi inspector screen shot - which I have attached. You can see a couple of "drops" on the graph.

My wireless connection randomly drops, or has no Internet connection, or says it has connection and Internet but no web pages load. Usually, what happens is it says I have no Internet connection. I have to disconnect and reconnect to get the Internet back. My ethernet connected computer never loses connection.
I am running Windows 7 with a Realtek wireless card. I have updated the driver to the latest. The wireless router is a D-Link 615 e1 using DD-WRT. The router is hooked up to a Brighthouse Arris TM402G/110 modem for internet access (note: this is my second modem. I had the same problem with another modem. Unfortunately, I don't remember the name.)
When the router is connected to a U-Verse 2Wire 3800HGV modem/wireless router (with the wireless turned off) I have no Internet disconnections. Everything else is the same (I just move the Ethernet cable between the two modems). Of course, one is just a modem and the other is a NAT router/modem.
I noticed that the wireless connection has a weaker signal when connected to the Brighthouse modem then when connected to the U-Verse modem. I therefore tried to up the TX signal strength on the router. This improved the situation (and the signal strength) but I still get disconnects. I also tried setting the MSS to 1492.

Been searching threads here and all over google. I have DSL thru Century Link.Router is Zyxel pk5001z. 2 laptops being used. ( well, they were until my MB fried out.) My laptop has Win 7, my girlfriends has Vista.- Dell inspiron 1525. Only had the service for about 2 mo's. My laptop was working fine wirelessly. Hers drops constantly.Currently hers is the only one being used.Sometimes shows the red x, other times just local only.- Drops and reconnects within seconds. I have set channel to 6 and 11. disabled IPC 6 in laptop adapter, uninstalled/reinstalled wireless card in device manager, checked for newer driver, checked for firmware upgrade in modem, set to g/n only, ( no option for G only) connection strenth is full. No wirless phones, no close neighbors, etc. I have read posts indicating the routers are junk, other posts saying Vista has issues with certian routers, but nothing that pinpoints my exact problem. Also, just re-loaded Vista the other day.
