Cisco Wireless :: AP Disconnected From WLC 5508?
Nov 27, 2012
We have WLC 5508 installed in our premises to which 80 1242AG APs are connected. Few days ago, all the APs all of a sudden disconnected from Controller and rejoined after 12 to 15 hours. when we try to investigate, there was regulatory domain conflict occur. But we didn't understand that those APs were configured with the same config before. How come they got diconnected and now rejoined without changing any configration in WLC?
Logs for both AP and WLC has been attahched here.

I am using guest solution with two WLCs , one inside and one as anchor in DMZ.we have also NAC guest server to authenticate the guest users. inside WLC is 5508 and had been updated to latest version 7.2.103.0 last Thursday.
now we facing problem with the guest SSID , after the user authenticate, immediately disconnected and to access again he has to authenticate again and so on.
Is there any Bug with the new version because the setup was working fine before upgrading.

I am at one of our remote offices and I am noticing my laptop, despite excellent signal strength is periodically losing IP connectivity on the wireless network. When it drops, all of my IP connectivity stops (pings fail, RDP sessions "await reconnection", etc...). The lower right corner still shows I'm connected to the hidden WPA2 Enterprise SSID. The only way to reconnect is to select disconnect on it, then click connect again. Immediately everything IP based starts working.
There is a 5508 controller in the headquarters. The site I am at has a 30mbps fiber point to point WAN to the headquarters. This site has 2 x 3300 series LAPs which are very good coverage. H-REAP mode is on so traffic terminates at the local office because it is more efficient than traversing the LAN twice for things like local file and print sharing, dhcp, proper active directory sites and services mapping, etc.

I was able to connect smoothly to any preferred connections in my area including my own. But now, it doesn't let me connect wirelessly to any of them. Now I typed ipconfig and this is what showed up.

I recently did a recovery on my laptop and had to put everything back to factory settings (losing all my music, programs, etc) due to a hard disk issue that I couldn't fix otherwise. After several hours waiting for the process to finish I logged onto my laptop - a toshiba, and realized that my wifi isn't working. The computer says there is an issue with the LAN being disconnected, but my router is communicating fine with other devices. Also, the side switch that turns wifi on and off is lit up (indicating that it is on) despite the fact that Fn + F8 are not responding on my computer. Generally, the laptop cannot detect any wireless devices or routers.I did another system recovery after reading about the issue, and tried turning it on and off, etc, but with no success.

The LAN adapter is disconnected since I'm not using it lmao. I meant the wifi adapter.So I bought this new laptop, ASUS G46vw but since yesterday I can't connect to the wifi. It connects but it shows as "Limited Connection - No Internet Access". I already went to the wireless adapter power proprieties - Power Management and unchecked the "allow the computer to turn off this device to save power" option. But I still get no internet access.

regarding my wireless card conecting to the internet.
Firstly what happens is I coonect to my hub which is a sky router without a problem, the internet isnt a problem and gaming and so on, but from time to time and sometimes once every 15 mins the wireless icon in the bottom of the screen says it has disconnected then a few seconds later it reconnects this may seem trivial but when i am playing games and surfing the web it gets extremely annoying getting cut off. I have tested this on another router and it is the same problem, so i know its not just one isolated router. stop the wireless connection from disconnecting randomly.

This has been happening for about the last two weeks now. Before we never had any problems. So now all wireless devices keep on getting disconnected almost daily.
I have a laptop, 2 Iphones, an Xbox 360, and a Xoom Tablet that keep getting disconnected. The Desktop, which is directly connected to the router via a cable is fine and never gets dropped.
I tried changing channels, and wireless mode is now G only. Still keep getting dropped.

If I have the wired cable plugged in to my laptop1 the wireless connection works fine. If I disconnect that wired cable then the wireless connection disconnects as well. I can watch this happening when I have the connection dialogs open showing the connection wizard dialogs.The other computers and printer work as expected without disconnects..I also have three other computers including another laptop connected to a switch and router.Here is the connection schematic:

I have searched so many threads concerning the problem I am having but have yet to find anything that works.On Sunday my husband changed our router. We have just moved from Sky to Talk Talk. Before the change, my wireless connection was absolutely fine.Now, everything else in the house is working on wireless fine (xBox, my smartphone, hubby's PC) except for my crappy Lenovo N 500 (XP SP3).Here is a copy/paste from my ipconfig /all:[CODE]

I have a fairly new Inpsiron 14z with windows 8 on it. Everything worked great out of the box, but all of a sudden my wireless stopped working. More specifically, it always says that the wifi is off, and pressing alt+f2 only cycles the bluetooth on and off, not doing anything about the wifi. Maybe I am just missing something stupid, I don't know. Here is my info:

i just setup an RV220W as my home router. Everything connected fine, etc. however, one of my wireless devices (it's a security camera) disconnects after 1 hour. I am able to reconnect the device if I either reboot it, reboot the RV220, or disable / re-enable the Port Forwarding rule I've established for it. Other wireless and wired devices do not have any issues. In the past, I had this same camera working for over two years over wireless while it was connected to a Linksys E2000 router. I enabled the logs on the RV220W last night, and the error message that I receive is: secureBit not set in GTK Msg2. I've got the same SSID on the RV220 that I had on the E2000, same port forwarding, same MAC address client list, etc. Like I said, none of my other wireless or wired devices disconnect at all, just this camera, which worked flawlessly until I switched routers.

I got 3 windows 7 pc's at home. IP V6 and IP 4 are enabled. I setup my wireless system and it worked 100%. After 3 months I add a LAN cable to two of my PC's. This is when it all started. My internet browsing became very very slow. When i shutdown the one machine it become fast again. I did the following. Pulled the LAN cable and it was still slow. I then put the cable back and disabled the Wi-Fi and it still was very slow. I rested the defaults and restored my old backup and it still slow. Now I can get any access to the internet any more. I the disconnected the netgear router and take a cheap router with only LAN ports and it work 100%. All the above i did with many router and server reboots.

So earlier today I purchased a new video card, a PNY Nvidia Gtx 560. After installing the drivers through the disc, I ended up getting he BSOD, and my PC just kept on restarting automatically. I fixed that problem, and found out that I should install the drivers for it through their website instead. So, after restarting my PC yet again, I tried using the Internet (Chrome) and found out that I have no Internet connection. Now, I am writing this on my iPad using the same router and modem that my PC is supposed to be using, but I keep on checking my WLAN adapter and it says that it is Not Connected. Now I have tried every forum, every post, EVERYTHING related to this problem and not a single thing fixes it. Also, when I do the ipconfig, everything says Media Disconnected and that's it. PS, I tried unplugging/plugging back in my modem and router PPS, Is it possible that when installing my new gcard and psu that I may have messed up with something internally?

Im using an old tower with XP SP3. Most if not all drivers are up to date.I recently have come home from college where the computer connected to the internet through a cable and i now have to use wireless.I went out and bought a Trendnet TEW-648UB Wireless n adapter, installed it and tried to connect to my home network.It has been going from acquiring network address to no connection every ten seconds then repeating. I am fairly sure that this is not the router because i am on my sisters desktop which is a wireless connection and im on the internet. so far i have:
checked to make sure that WZC is enabled, it is.
tried checking and unchecking the Use Windows to to configure my wireless network settings
enabling and disabling my adapter
reinstalling my adapter
repairing connection
disabling any and all firewalls
ipconfig /release
ipoconfig /renew
netsh int ip reset reset.log
netsh winsock reset catalog
lots of computer restarting
and for good measure i pinged 192.168.4.1 and ping 24.229.54.212 not sure why but kinda frustrated so why not
here's the cmd stuff:

New E3200 router (a few weeks old).
Using the manual settings under Status/Router and clicking the Disconnect button (by Login Status), the page reloads, and say I am disconnected.
Without any input from me, about 30 seconds later the page reloads and say I am connected.
Clicking disconnect, closing the tab and testing my connection proves that I'm not actually being disconnected at all. I cannot force this router to manually disconnect.
Is this a firmware bug or is there another setting else where that prevents me from manually shutting down my connection?
Edit: Firmware 1.0.04 build 1 Apr 10, 2012

I bought a WAG160N ADSL2+, I configured it and all the computers can connect to it with wireless. But the problem is sometimes the connection between the wireless adapter and the router will disconnect and I'm not able to connect again (the computer screen in de bottom right corner has a red cross in front of it if you know what I mean). It can take hours before it will be able to connect again. The only way to have the connection back up is to turn off/on the WAG160N. This happens mostly on my machine (windows XP Dlink Dwa-131 adapter and with the adapter that came with the WAG160N) and afterwards on the other machines. Its like the router doesn't want me to connect anymore.

My computer is a desktop in a differet part of the house, away from the main computer. My computer is hooked up with an AE1000 Wireless USB. This USB is wirelessly connected to a Netgear Extender (Repeater) for a better signal strength. This Repeater is wirelessly connected to the router on the other side of the house, plugged into the main computer.
So my problem is, when im working on my computer or gaming on my free time, it randomly disconnects. My signal has a (!) inside of a triangle at the bottom right of my screen. I run the automatic troubleshoot on my Win 7, and it says either "DNS server not responding" or "Your computer is working properly, but some of your devices are not responding". Other times it works just fine and i run troubleshoot alot and it doesnt find a problem. Some days its running at 144 Mbps others 6.5...
I have checked that all of the devices are uptodate. .I've contacted GeekSquad and they said there was no problem. But obviously for them to connect to my computer the wireless has to be working, so they didnt find anything because it worked for the time being.I'm just woundering are there any capability issues with my wireless? Or any other problems im not aware of?

Users are facing issue since a long time now . Whenever user connected to wireless is idle say 10 -20 seconds he gets disconnected This happens for all the users and even Mac/Win 7 I changed Activity Timeout on AP and even rebooted but still when I do show dot11 associations all-client I see activity-timeout
Users don't get disconnected when there is continous flow of data its only when user is idle
When user disconnects and hit refersh it starts working again

I have two routers, a Telkom Mega 100WR and a Belkin F6D4630-4 v2. First I used the Mega 100WR and it randomly disconnected, then Belkin (which is new) and that too randomly disconnected. The funny thing is, both of them use to work.

I will be working from home half the time and am trying to get set up. So here it goes:
Took PC #1 home and hooked everything up. Could access Internet.Had to bring PC #2 home because #1 didn’t have the programs I needed.Hooked #2 up, no internet access.Tried different network cable – no access.Tried different router port – no access. (router port light doesn’t illuminate, neither does port on PC)My personal PC that uses the same router has internet access.Hooked #1 back up as a test – could access internet.Hooked up #2 again, did a Run, cmd, ipconfig and got “media disconnected”I brought #2 back in for a PC tech to look at. He hooked it up in his office, had internet access.Took it back home and hooked everything up.The port lights illuminated on startup; but after it got to the desktop, lights are off.Tried ipconfig again, "media disconnected”. IP address doesn’t display.
All the while I have internet access on my own PC, plus when I hook up #1 to the same port using the same cable, I have internet access, which led me to believe it's something wrong with PC #2.Tech is saying it’s a problem with my router (Cisco E2500), which I restarted too.
