Cisco Wireless :: LAP1041N Cannot Stay Connected To WLAN Controller
Feb 27, 2011
Just bought two new LAP1041N APs to add to a dead spot on our campus. Well when trying to set them up the will not stay connected to the WLAN Controller (model 4402). The new APs boot fine, and will even appear in the controller for brief moments, but after a few seconds they dissapear and start showing the discovery status light pattern (green, red, amber). Just wondering if I am doing something wrong with these APs, or what the issue could possible be.We have 10 other APs that as soon as we connected to network were detected by controller and we configured from there. Most of those are 1010 or 1020s, we have a few 1131s and 1100s.

I am struggling with the following issue. I have 6 1130 Accesspoints in lightweight mode connected to a 2106 wlan controller which runs software version 7.0.98.0. Everything seems to work fine. Clients can connect to the wifi network. However, they don't get an ip address from the dhcp server which is on the same subnet as the wlan controller. See attached screenshots for configuration. I have also tried the internal dhcp server of the wlan controller, but the same problem remains.
The logs says: Dropping primary discovery request from AP e8:b7:4x:xx:xx:xx - maximum APs joined 6/6 There are 6 AP's connected

I have multiple 1230AG wireless access point in autonomous mode that I am migrating to lightweight mode so that a 4402 controller can manage them. I already migrated 4 of those APs with no problems using the Upgrade Tool version 3.4 and now I have one that just refused to upgrade version.
I ran the upgrade tool for this AP alone with the same parameters as others. It is now on lightweight version 12.3.7-JX9 The upgrade procedure went smoothly, the SSC was created on the AP and added to the authorised list on the controller. The AP boots up, gets an IP by DHCP, tries the controller via DNS, gets to it. It joins it then disconnects. Its FastEthernet interface keeps doing down/up every 90 seconds or so.
In my controller logs I see:
*SNMPTask: Feb 22 19:39:17.135: %LWAPP-3-INVALID_SLOT: spam_api.c:711 Invalid slot identifier (0) - ; AP 00:13:.........

We just recently signed up with Time Warner Cable for internet access. The modem they gave us is also a wireless router. So we set up our wireless network like we should but for some reason my desktop computer won't stay connected to the new wireless network. We have a laptop downstairs that doesn't have any problem staying connected. I can connect to the neighbors wireless network and I have no problems staying connected. I can't figure out why my desktop won't stay connected to our network

I received my new XPS 15 yesterday and it will connect to the wireless for a minute or two, then it is gone! I have 3 other computers on the network, so my internet/router is fine. Dell support tried to remotely fix it for a couple of hours last night.

I'm having trouble getting my laptop to stay connected to my wireless internet. This problem only occurs with my laptop. Other laptops in the house are able to connect no problem. It stays connected for about 5 minutes at a time, then loses connection. I have to disconnect and then reconnect all the time just to get online. I've had the router about 2 years with no problems. This just started happening only to my laptop yesterday.

When we first bought the computer, it worked fine but we sent it with my oldest sister to college and she messed it up. Since she brought it back, it will not stay connected to our home wireless network. It will stay connected for about an hour and then it will quit and then the computer has to be restarted for it to work again. I checked for all the updates and the wireless card and everything was fine.

There is a discussion of this going back many months in the previous forum. My initial post there has had over 600 views and I see that an IT administrator with 10 BB has the exact same problem. I have replaced my BB 4 times and all of them behaved the same way with this CISCO WAP4410N:
THE PROBLEM: The 4410 drops the WiFi connection to a Bold 9700 BB (using WAP2). I got an old Motorola about 6 years old out and found it works fine with the BB as does most of the public hot spots. This is an issue with the 4410. An IT Admin has found (an posted in the eariler forum) that for some reason the key change is not accomplished when issued by the 4410 but it works for others. The Admin discovered that if he set the timout on the key change to maximum he only has to restart the 4410s every 10 days.
So I have the 4410 for my 5 computers with which it works fine and beside it the old Motorola for the BB.
When I called support about this I was told that "we don't support connections to Blackberry." I hate to have to sell this thing on Ebay and buy another brand becuase of this. Seems that Cisco would fix it.

Background: Wireless credit card machines can't stay connected to the 5508 controller 7.0.116 / 1142 ap wireless system. MAC address of one of the wireless hosts is 00:12:0e:ec:ce:97. AP servicing them is d4:a0:2a:99:34:60. Hosts are able to connect to the network after a reboot and stay connected for random periods of time but then don't come back unless you manually reload them. I have 3 in total in the same room services by the same ap.
I have the output of debug client 00:12:0e:ec:ce:97. Output showed 802.1x 'timeoutEvt' Timer expired for station 00:12:0e:ec:ce:97 so I increased the value to 4000ms on the controller but am still having the issue.
Note that the output below is the state the client stays in after receiving the timeout (802.1x 'timeoutEvt') showing subsequent attampts. The only way to get them back on is a reload of the credit card machine.

I'm having trouble getting my laptop to stay connected to my wireless internet. This problem only occurs with my laptop (other laptops in the house are able to connect no problem) and with this particular wireless box (my laptop has no problems connecting and staying connected to other wireless networks, wi-fi, etc.).
I am able to connect to the wireless but it lasts only for a few minutes before connection is lost, so I basically have to connect to the internet through a ether cable (?) plugged into the wireless box.
I can't work out where the problem could be as the wireless works for other computers, and my computer works with other wireless networks!
I don't know if it matters but I am using a Toshiba satellite running on Windows 7.

I have a Linksys WRT120N that I use at home for wireless connectivity, with a total of three laptops that connect wirelessly, plus my Samsung Intercept phone. It's a mixed Wireless G and N network; the laptops run Windows XP, Windows Vista and Windows 7.The issue I'm having is this: the computers and phone do not stay connected on this network. Here's a for instance:Monday: I am able to connect wirelessly to my network with my laptop.Tuesday: I cannot connect to the same network; repairing the connection does nothing.Now substitute my laptop for the one running Windows 7, or Vista, or my phone.At that point, I have to power the router down and power it back on, and then we're back in business. The router currently is running version 1.0.05 of the firmware.

any luck getting Nest thermostats to stay connected on a cisco wireless network. We are running 5508s (ver 7.2.110.0) and the thermostats are connecting to a 3502. The WLAN is a locally switched FlexConnect SSID.
According to nest there are two potential issues - NAT timeout and wireless networks that do not play nicely with devices that sleep for long periods of time. I've configured static NAT translations for the Nests, so that shouldn't be an issue. Nest says "Nest uses Wi-Fi 'Power Save Mode' to allow it to sleep and charge its battery while remaining connected to the internet. Not all Wi-Fi routers support this feature or implement it correctly. When they don't, Nest will have difficulty sleeping and will restart in an attempt to reset its network connection. This may happen repeatedly if your Wi-Fi router is incompatible with the 'Power Save Mode' feature." I've tried increasing the DTIM timers to no avail.

I have a Tenda router and Realtek USB wireless adapter. My 8200 has XP svce pk3. The adapter will not stay connected. Some times it shows connected with 100% signal strength and after few seconds drops out. I cannot find any radio switch on this laptop. Fn/F2 does not work and there is no mention of wireless in the bios settings. I feel that the radio is not switched on but how do I do this?? Is my configuration incorrect?

I bought my son a PS3 for Christmas and we had one laptop at the time and we had them both connected wirelessly to the internet and they both worked fine. We recently purchased another laptop and when we connected it to the network, now the PS3 will not stay connected to the internet. It is says that the connection is good when you test it, but when you try to download the updates, it stops and says there is an error.

My computer constantly fluctuates between being connected to the wireless network/internet and "connected with limited access" in which I cannot access the internet. I am then forced to disconnect and reconnect. I then have 1-20 minutes before it drops back to limited connectivity.[CODE]

I have many computers and work on a wireless network. We live in a very large multi-unit building in a very large city. We hadn't had any issues with connectivity for a while, but recently the PCs in the office cannot stay connected for more than a minute or two. It happens to our two desktops and one laptop; the only computer that seems immune is the lone apple laptop. The PC laptop has much less difficulty staying on when I sit in the room with the router. The office is literally the next room over, less than 20 feet. The network still shows up as an available network, it just won't connect. All the impacted computers will be fine for maybe a minute and then will all drop out at the same time. Rarely (like once in the past month) there will be no issues at all, and we can stay on all day. We have changed the channel of it a few times, but there are at least 15 other networks nearby. The router is relatively new, it is a Netgear Rangemax Duo wireless n-adapter. We have gotten to the point where we have no idea where to go next.

I have a 2 yo computer, custom ASRock G31M-S R2.0 with XP. I have QWest PK5000 wireless modem. I do not have a wireless computer, have a desktop. I am connected to the Internet by Century Link. The ethernet light doesn't stay on, and therefore I lose my connection to the internet. Sometimes for days at a time. Everything is plugged in. I looked at the wires outside my house to the area where my computer is located. Looks good. Century link says it is my computer.

I have an AP, model AIR-LAP1041N-A-K9. How does the AP work? How does the AP broadcast?. Is It a circle and the AP is the center? Does the AP broadcast more front than back? Have any blind spot? I see the datasheet [URL] -

I have a PC at home which is dedicated to one specific task, and need it to be connected to our company VPN at all times. This PC gets accessed by another remote worker (RDP), through the VPN.
This works fine with the PC at my home office connecting via the Anyconnect client... for a few days, then mysteriously disconnects and doesnt automatically reconnect, with the following Anyconnect error;
"The vpn connection to the secure gateway was disrupted and could not be automatically re-established. A new connection is necessary, which requires re-authentication".I have to manually reconnect and re-enter the password, after which it connects fine.
I have looked on the central ASA5510 (which all clients connect to) and set the idle timeout to unlimited for the appropriate AnyConnect profile and group policy, I cant seem to find any other settings to allow it to stay 'always on' from the client.
I am wondering (but am not sure if this is the problem) if it is perhaps because I am on a normal home broadband connection, which uses a dynamic IP, not static. My ISP (Sky) cannot provide a static IP for my public interface..

I've seen a couple of expired threads on this subject, so I'm sorry for resurrecting it! I have just got a ZyXEL P660HN-TxA router/modem on my home landline to use for wifi with my smartphone. The problem I have is it won't stay connected for long. It connects quickly & browsing is fast for a few minutes, but then it just kicks me offI am still connected to the wifi, but I can't browse anything or re-connect to the internet. Sometimes I can use it for up to 10/15 minutes before it kicks me off. I have to reset the modem, or turn the wifi off then back on via my phone.

My laptop was recently reset to factory settings and had the hard drive wiped, since I got it back, I can't remain connected to the internet. We have a second laptop running off the wireless that hasn't had any issue. I try to disconnect from the network and reconnect and sometimes after 2-5 attempts, I'll browse the internet for 5-45 min and then it will say it can't identify the network or that the computer is only connected locally.

Ive been having an issue for the past 3 weeks keeping my primary wired PC and the wireless PCs in my home network connected to the Internet. The internet constantly disconnects intermittently (with no rhyme or reason) and have tried everything I could do to try to resolve the issue. I connected my wired PC directly to the Optimum Online Cable Modem (Arris Telephony Modem v 3.0) I use to connect to the internet and it still has connection issues. Most of the time when it drops the connection, the network icon on the taskbar says I�m still connected to the internet. Only after a few minutes will the network icon finally appear with the yellow exclamation point over it. When I right click the network icon, I will check the network and sharing center and will click on the red x over the connection from my router to the internet. Sometimes when Windows checks for internet connection problems, it will state that it cant resolve the issue, and other times it will state that the DNS server isnt responding or cannot communicate with Primary DNS Server. I�ve had my ISP cable guys check my cable wire (coaxial cable wire) for packet loss, swapped my old router for anew one (twice), readjust the connection outside for a specific low node issue, and did 3 or 4 trace routes, conducted a multitude of ping tests, went on speedtest.com to check the signal strength and they state that everything looks great on their end. I also used different Ethernet ports built into the motherboard of my PC to see if my network adapter was the issue, but my internet connection it still continues to drop, even when only my pc is wired directly into the cable modem. I even changed the Ethernet cables themselves to see if they might have been faulty, but it still continues to drop.
I forgot to mention that I did the flushdns and registerdns commands , plus reset the TCP/IP, but my internet connection still continues to drop. The only thing(s) I have not done is change the network adapter completely (install a new Network PCI adapter ) and have the cable guy re install an entire new coaxial cable wire, of which myISP is adamant that I don�t need to have done since when I am able to connect to the internet, my signal strengths and speeds are great (download speeds of 32mbps and upload speeds of 5mbps). I know I�ve said a mouthful, but Im at a loss of what I should do next. When connected to my cable modem through my wireless N router, ALL of my PCs (my wired PC and my wirelessly connected PCs through my home network)will disconnect from the internet . Both the cable modem and the wireless N router still appear to be online (none of the lights on the front of the modem or router have changed ) I�ve even considered the strength of the ethernet cable itself, possibly thinking that the ones I have may not be strong enough for my internet speeds (purchased a CAT 6 Networking Ethernet Cable). My router , OS, cable modem, ISP, motherboard, and built in network adapter specs are shown below;
ISP: Optimum Online (with Boost Service) OS: Windows 7 Ultimate (with latest Windows 7 Service Pack 1 updates) Cable Modem : ARRIS Touchstone DOCSIS 3.0 E-MTA Telephony Modem TM802 Wireless Router: Netgear Rangemax Dual Band Wireless N Gigabit Router WNDR3700 Motherboard: ASUS Rampage Formula Built In Network Adapter: Dual Gigabit LAN (2 RJ45 Ports)

I have a Lenovo G550 that is running Windows7 and has been for several months!nyway, it will connect to the internet via wireless, but it only stays connected for a few minutes. I have other computers in the house and they remain connected, so that leads me to believe it's not the router.Thus far I've done a few odds and ends suggested on other sites to eliminate my problem, like taking the battery out for 30 minutes, changing the power setting.

I'm trying to change some network settings, but the router is unresponsive when I try to connect to its ip address. If I reset the router it opens a 20 second window where I can log in, but then goes unresponsive. I have encountered this on my main pc connected wireless, and duplicated the results when wired in with my netbook.

I checked on internet and I found the 2500 series Controllers are compatible with Cisco 1142N (AIR-LAP1142N-A-K9) APs. But I would like to know How can I find the exact supporting version of controller for Cisco Access points?

The issue is a odd one, I will be playing a game League of Legends, Star Craft 2, Diablo 3, or Tera and I am in Team speak then about 5 minutes to an hour I get "Connection has been lost". I am either booted from the game or Team speak, never both. It's completely random when this happens and at times it takes a while (10mins at the longest) for me to log back into what ever program I have been disconnected from other times the reconnection is instant. I have gone through forums, talked to support for the games, had my ISP come out and test my lines and replace my modem and network card, Ping tested, Speed tested and the results were stellar, but I still have the problem and so I feel that the problem is on my end. I have a self built machine, My OS is Windows Vista 64-bit, Mobo-EVGA 132-CK-NF79 2, Processor-2.85 gigahertz Intel Core2 Quad.

I have a Toshiba Satellite E205 running Windows 7 and it will not always stay connected to the internet. If I am doing something like watching movies online or downloading large files I will get kicked off the internet. Then in the taskbar there is an X over my signal bars. After that nothing I do will get it to find a wireless signal. The only way I get the signal back is if I restart the computer. I know it is not my internet because my Blue Ray and iPod can stream movies just fine without losing their signal.
