Cisco Wireless :: AIR-AP1141N-A-K9 VID - V04 Clients Disconnect Often
Dec 6, 2011
The environment: 20 X air-ap1141N-A-K9 (these are standalone) in three different buildings with either 1 or 2 units per floor depending on sq. footage. IOS is c1140-k9w7-tar.124-25d.JA1.
Problem Users running various tpyes of wireless cards on windows XP SP3 get disconnected periodically throughout the day whether they roam or not. This disconnect problem started happening after we replaced older 1200 series units running wpa and tkip and replaced with 1141n running wpa2 with aes. Users running windows 7 do not get disconnected. However there are very few W7 users on campus as this point in time.
I set up a single test unit shown below and associated two laptops to see if they would disconnect. Not once did I lose connectivity. NAME: "AP1210", DESCR: "Cisco Aironet 1200 Series Access Point"PID: AIR-AP1252G-A-K9 , VID: V03, SN: FTX1339903J NAME: "Dot11Radio0", DESCR: "802.11N 2.4Ghz Radio"PID: AIR-RM1252G-A-K9 , VID: V01, SN: FOC1337107F IOS: c1250-k9w7-tar.124-10b.JDA3

I have a WLC 5508 in my datacenter, and 1142s configured with FlexConnect at a remote site.Two issues:Some APs 'die' from time to time where I cannot ping them anymore and they do not service any clients. I can reset them from the WLC after which they work again. I have some clients in the building (same area) who lose connectivity from time to time and are unable to reconnect to the wireless. I am seeing errors that the gateway cannot be found or there is not a valid IP. restarting the AP closest to the clients fixes the issue. I have replaced the AP and connected to a different port on the switch.

We have a setup where clients on the internal network send/receive their emails through Microsoft Outlook client, while the Exchange server is hosted on the internet, outside the organization.The clients are connected to a Cisco switch, behind an ASA5510 Firewall. The Firewall is connected to an internet router, with double NAT (On the ASA and Router).
the outlook clients disconnect from the Exchange server, sometimes for hours, and then reconnect again. During these disconnections, the same client PCs are able to browse the internet normally. There are no restrictions for the traffic going from the inside to the outside. During the disconnections, if we try to connect using a public IP bypassing the ASA & router,.

I just purchased the AP1141N and I have created a logon account to access the device via URL which works fine but after 10 minutes it logs me out and requires that I log back on. Unfortunately it won't allow me to log back on unless I reset the device then I have another 10 minutes before it asks me to login again but then it won't accept my logon again without a reset.
I can logon with my account via the console logon but I don't know how to configure the access point via command line so I use the web interface. I have disabled the timing for security but didn't work.

I have 4 desktops cat5 to Dlink DIR 615 router. All work fine. Any wireless clients, laptop or netbooks, see the desktop computers for a while then disconnect somehow. All machines can see the Internet through the router at all times. The desktops disappear from the laptop/netbooks but the wireless machines can be seen from the desktop computers but clicking on them gets 'Access Denied' message after a wait.3 desktops = XP, 1 98SE. All laptop/netbooks = XP

We currently have an ASA 5520 communicating with 10 ASA 5510's, all on static outside addresses. I was asked to add 5 additional 5510's on dynamic address. All worked well in testing until it was decided that some of the dynamic clients needed to talk to each other.
My testing shows packets just dying in the 5520.

I have just set up a wireless trendnet router. Everything is set up normal and its working correctly, it correctly assigns internal IPs to wireless devices. The problem is though that for some reason we all get disconnected in games for instance and some games more than others. Rift disconnects every 30 seconds to 1 minute, World of Warcraft disconnects often, Live Messenger disconnects as well, Age of Empires Online can sometimes work fine for hours, then sometimes disconnect every now and then. Steam doesn't disconnect. Its more or less the same on any of our laptops. (all running Windows 7 64 Bit Home Premium or Professional)

I have a Netgear WNDR4500 running the stock firmware, acting as a router for my home. I also have 2 routers that are flashed with DD-WRT (Linksys WRT54G and Asus WL-520GU) running as client bridges. The Netgear is 192.168.1.1 and the other 2 client bridges are 192.168.1.2 and 192.168.10.3. The Netgear router is performing DHCP giving addresses from 192.168.10.100 to 192.168.10.254. I have numerous machines connected to the Netgear, wirelessly and wired, and numerous machines wired to each client bridge. All machines have IP addresses that are 192.168.10.100, 192.168.10.101, 192.168.10.102, etc... Everything is working fine, but I have one question: When I access the Netgear router, it shows the client bridges as clients, machines that are wired and wireless to the Netgear router are listed as clients, but the client list does not show any clients that are connected to the client bridges. I assumed that since the router is performing DHCP that all clients would show up.

With the advent of all these consumption devices; smart phones, tablets, net books, gaming systems, laptops etc... I keep seeing recurring themes at a bunch of locations.I've recently been in 3 locations where once a certain number of clients access a wireless router (not bridged, not strictly AP) another client gets disconnected from the network. This seems to be happening more and more.

I have set my WLL modem to connect automatically to my laptop when switched on. It does connect and work well until there is another modem in the neighborhood coming online.The task bar icon shows I am still connected but the connection is gone. I tried troubleshooting the network, reconnecting from laptop giving the passkey, log off and log on but none of these work, except restarting the modem. This has become a pain and has been so since I purchased this 4 months ago.Is there a setting change that can be done?

One of my 7921 phones disconnect ten time an hour and during conversations. Sometimes, people who call on this phone are redirected to the answer message.This phone is connected through WIFI network and Cisco Callmanager 4.2 manage all phones (we have about 80 phones on the network). I thought it was a problem with the phone but I exchange with another one and it's exactely the same problem. The problem is just for a line in particular. All the 7921g phones in my company are configured from mac address in the call manager. This problem occured after a storm but I'm not really sure that it's related to.

I have a HP G62 Laptop that's less then a year old (replacing a Dell we had for several years without problems) and a 2Wire router with ATT DSL that we've also had for years. Ever since we've had the new laptop we've been unable to use the wireless without problems. Periodically, (maybe once an hour or so) if the laptop is connected wirelessly it will make the router disconnect from the internet and cycle off. The router lights all go red, it cycles back on, green lights come on and re-connects.I've had ATT run a line test, had them send technicians here 3 times, they've gone through the house and followed the line to the box, trimming branches on the way. I've gotten a new router and I've tried a USB wireless adapter for the lap top. However, as soon as the wireless is disabled and it's plugged in by ethernet all of the problems go away. This would be fine if it was mostly used at a desktop but it's mostly used on the couch/around the house and the ethernet cables get in the way and keep breaking.

wireless N adapter wusb600N and win 7 pro fully upgraded:Ive tried this with multiple adapters and multiple 3g providers/usb modems. When I connect the adapter, after a while, the 3g modem disconnects and turns red, and the modem connection software says it cant find the usb 3g device. It feels like the windows is somehow mixing the adapter, and the 3g modem or somthing. Again this same problem happens with multiple devices. Is there some settting im missing.

Region : UnitedStates
Model : TD-W8960N

Firmware Version : 1.1.1 Build 120912 Rel.67406
ISP : centurylink
First a bit of background. At the end of December, my centurylink modem finally had enough problems with disconnects(was 6 or 7 years old), and Centurylink sent out a new router/modem. The new modem/router, a Zyxel, worked great, and all was good in my house hold. Then I got the bill and found out that unlike the previous modem they had sent me, this one I was paying a lease payment for. At which point I returned the Zyxel which gave us the best service we'd ever had, and bought this TD-W8960N. The reviews were glowing, setup was easy, but we started rather quickly to have disconnects. A call was made to Centurylink and they confirmed service was working, and since the modem/router was not theirs, referred us back to you. I called and after considerable time on the phone, all I was basically told to do was a hard reset to the modem. When the unit finished booting back up, internet was restored. Of course it was restored everytime we reset it for a while. At that point I was told that since the unit was working, that there was nothing left to be done. Since that time, it has disconnected us from time to time, and then in the last 2 days, sometimes it won't stay connected for more than a couple of minutes. My wife is very unhappy-she is a gamer, and a disconnecting internet is very very bad for an online gamer.
It seems that the further it gets away from a hard reset,the more it disconnects. After 6 soft resets (unplugging) today, I had to do another hard reset to get back on to register here and post this message. Is this a known problem for this unit? Is there a fix for this unit? Or, do I just need to return it to Newegg and try another manufacturer?
Again, the "leased" Zyxel gave us no problems for the month or so that we used it.

My USB Belkin Wireless G Network Adapter seems to disconnect whenever I remove another USB device (usually a memory stick) from the PC.The problem started when I accidentally updated the driver via Windows. It didn't seem to work at all with this updated driver and I couldn't roll back or do a system restore to fix it. I'd done this before and ended up doing a complete re-install of Win 7. This time I did an upgrade install and the driver problem was cured.I'm running a HP XW8400 with Win 7 64 Pro which has been faultless for the 5 years I've had it.The only other change I've made recently is that I've stopped using a D-Link USB hub and started using the USB connectors on the HP LP2465 monitor.This only affects the wireless and no other USB devices.
When it disconnects, Win troubleshooting goes through the motions and reverts to LAN and doesn't see the wireless USB at all. This also happens if I don't use the troubleshooter.Device manager shows the driver to be working, but the wireless USB doesn't function even if I connect it directly to a USB port.The router is still working as all other devices in the house are connected.The only way around it seems to be a re-boot, but when this fault happens the PC gets stuck at "Shutting Down". Without the fault, re-boot or shut down works fine.When it happens I have to power off and on. This usually works fine but every now and then I notice the device driver for the Belkin is disabled.I've found a workaround in that I can take out the Belkin USB before removing another USB device. After the USB stick or whatever is removed if I then reconnect the wireless USB it reconnects fine.

I've had an E4200v1 in use as my home's main router for about 3 mos. And while many others have reported disconnect problems (I think), I myself have never seen any. My router and its N & G wifi networks have been rock solid. Until yesterday that is.Now all of a sudden, most of my family is complaining about wifi disconnects, slow speeds, etc. (My primary PC is hard-wired so I don't see any problems whatsoever... the problem apears to be wifi-only)And the Apple devices (OSX & IOS) seem to have the most severe problems. But Windows devices have also seen problems, just not as critical.Also, it's worth noting that I've been running 1.0.04 the whole time, without any problems... it seemed relatively stable to me. That is until yesterday.
I've bounced the router, I've disabled/re-enabled Wireless G network. I've switched mode from "mixed" to "G-only" back to "mixed". I've changed the channel width back to the default of Auto (I had been using 20Mhz), which increased my throughput (as measured by Qcheck) so I'm leaving it "Auto".

I bought an EA 3500 refurbished through linksys. I can't configurate it using the CD-Rom. Always said "can't find your router". So I flash with the classic firmware, and it fixs the problem and automatically upgrade to smart Wi-Fi. That being said, whenever I plug in a portable hard drive, the router disconnect from internet after a minute. I tried my seagate HDD and also my flash driver. Both Lost internet after a minute or so. So I think it is probably the router's problem.
