Cisco Switching/Routing :: WS-C3524-XL-EN HP Flaps Up And Down / Disconnects / Reconnects Continuously
Mar 2, 2009
latest OS release for this Model number: WS-C3524-XL-EN switch. I currently am running Version 12.0(5)WC17
The reason is, I'm having some issues installing some HP PC's connected to this switch. The nic card on the HP flaps up and down, disconnects/ reconnects continuously. The only way I get it to stop is to bring down the speed on NIC or the switch port to 10mbs.
If I add a nic card and disable the system board nic all is well.The HP rep says that Cisco has a patch for this unit. Any recent patch or what the latest OS is for this switch?

The switch ws-c3524-XL with c3500xl-c3h2s-mz.120-5.WC17.bin not support the command dot1x?
I ask that because i´m unable to write this command: aaa authentication dot1x default group radius
And enable 802.1X authentication on the interface with this command: dot1x port-control auto

I am in the process of updating the software on a Catalyst 3500 series switch. I deleted the old bin file and copied over the new file via xmodem.the image I used is:
c3500xl-c3h2s-mz.120-5.WC17.bin
Once the xmodem copy is complete I performed the following sequence of steps:
File "xmodem:c3500xl-c3h2s-mz.120-5.WC17.bin" successfully copied to "flash:c350
0xl-c3h2s-mz.120-5.WC17.bin"
switch: dir flash:
Directory of flash:/
[code]....
The last output is where I am stuck. What am I missing?

I'm having this discconnection and reconnection issue every 30-45 minutes, and it is extremely annoying. Especially when playing online, I always get disconnected from the server. I have tried so many things to fix it, but no change at all. I've tried to change my DNS, tried to plug the modem directly to my computer, but the problem still existed! When I troubleshoot from the windows, it says: your computer appears to be correctly configured, but the device or resource (DNS server) is not responding.

My wireless internet constantly disconnects and then reconnects right away for seemingly no reason. I can't find a pattern, sometimes I have no dropouts for 6 hours, sometimes it happens every 20-30 seconds for a few minutes. I've checked online and i tried to do some research on it but i couldnt find an answer, i remember typing something into the cmd and it said that something was disables, just cant remember what i typed into the cmd. Also, when my ISP raises the network speed, my router or whatever it is can't handle it so i disconnect and have to call them to set it down.

We are facing issue with highly frequent interface flaps on Cisco 4900M switch only for module WS-X4920-GB-RJ45. Strange thing is no complaint from the users/server teams for any traffic interruption.
Switch: Cisco WS-C4900M
Line card: WS-X4920-GB-RJ45
IOS image is cat4500e-ipbase-mz.122-53.SG4.bin
There are several other smilar model & linecard/inventory of switches with exactly same IOS image, however there are no issues with them.

I have an HP Pavilion dv7 laptop running Windows 7 (64bit) SP1. Recently, my computer was attacked by some really nasty malicious software. Nasty enough that it not only got past my security software, it permanently disabled it.I was still unable to repair/replace my security software. Finally, the support tech just gave up on me, and I ended up utilizing the restore feature provided by HP to restore my laptop, supposedly to factory condition. After the restore, everything works great except for my mapped drive.

I'm having a problem with my wireless internet connection. Just recently my roommates and I got cable internet and a wireless router for the house. Since connecting to the wireless router, it keeps on disconnecting me and then reconnecting once every 2 minutes about. The disconnection last for only 10 seconds but is very annoying and disrupts everything I'm doing on the internet. What is going on and how can I fix it?

About a week and a half ago my n5050 began disconnecting from the internet and reconnecting about 20 seconds later. This happens pretty frequently, about once a minute or so. It makes doing anything over wifi almost impossible. Plugging in an ethernet cable (directly from modem or from wireless router) keeps the internet connected. My wife's laptop, coincidentally also a Dell, doesn't have this problem. Neither do mine or my wife's iPhones or my kids' Nintendo DSs. I'm totally lost. I've tried uninstalling the adapter, updating it, updating the firmware on the router, changing the power options on the wireless adapter, changing wireless channels, uninstalled and completely removed AVG 2013, tried a clean boot, and more. I'm getting real close to scrapping this computer and going with another brand...
Here is my system info:
Host Name: OS Name: Microsoft Windows 7 Home Premium OS Version: 6.1.7601 Service Pack 1 Build 7601OS Manufacturer: Microsoft CorporationOS Configuration: Standalone WorkstationOS Build Type: Multiprocessor FreeRegistered Owner:

I just bought a m14x alienware and I have the Killer-Wireless 1202 wireless card on it, and I have a 2Wire router from AT&T running in ch 1 at optimum 10. Also, I have another laptop that connects to the same router and this does not happen to it at all.I can connect to the internet fine but when i start browsing, I randomly disconnect from the internet and connect to it again within seconds, and my laptop never shows that it looses internet. I first noticed it when I was using Skype, i started browsing the internet while I was in a call and that's when it happens most, it disconnects, puts the call on hold and says that I'm offline on skype, and within a few seconds I'm back on. This also happens when I'm gaming and it really becomes a hassle when i have to start the game up again because of these disconnections. Rarely i do see a screen from the actual router to check the wired connections of the router and then test the connection when opening a website (any website), when i press test connection (without doing anything) it tells me that the connection has been resolved and to close my browser and to open a new one. However, most of the times, the pages load fine when I'm browsing, I do notice there is a small lag when the disconnections happen, but the page loads up fine after a few seconds, no need to refresh.
I tried releasing and renewing my IP but i get a message that no action can be taken when media is disconnected? I don't know if that has anything to do with it.I also updated the Wireless 1202 Driver with the bigfoot update, although I'm not sure if i did this right, I unzipped all the files where it told me C:/user/driver/wireless (example) but i never got a window to proceed after that, and when i went to the folder and ran the application, it asked me if I wanted to uninstall all components, which is when i canceled and left the newly created files there.

my internet will disconnect sometimes for a split second, for a few minutes or for hours at a time. My boyfriend and I have directly connected his computer to the modem, and the internet is working. I have also called our ISP and asked if there are any problems on their end, and our modem is working fine with no issues. So we had come to the conclusion that our router was at fault. It was a Linksys E1500, we investigated online and found that many people had the same problem and it was solved through buying a new router. We have since bought a new router a D-link N150, it worked for a week and a half, but now our internet is back to disconnecting randomly throughout the day. We have tried resetting the router back to factory settings to an avail.

My WRT400N wireless router continuously disconnects and I have to keep restarting it. I have tried to download an update for it, but once i download the zip file and try to open it, it just keeps duplicating the file.

I am having issues with frequent bgp flaps on the Cisco 7200 series router from past 1 week. I have raised a ticket with ISP but couldn't get any resolution from them as the flap is for about 2min.When ever we see BGP flap, we are not able to ping the remote end IP, Also at that point we drops on the interface connected to ISP.

As of right now, I don't have access to the PIX itself but can get access to it later today. In the meantime, I wanted to get everyone's opinions on a very peculiar issue I'm seeing with Internet download speeds.
Prior to last week, my company was utilizing a Sprint T1 connection for all visitor traffic. Attached to the Sprint T1 was a Cisco router -> C3524 Switch -> PIX-506E device.
Last week, a decision was made to upgrade our bandwidth for our visitor traffic and we replaced the T1 with a Comcast Business Class cable solution. The bandwidth we ordered was 22Mbit down/5Mbit up. From the cable modem that was provided, we connected it in the same manner -> C3524 Switch -> PIX-506E device.
Since the change, I noticed that our visitor V LAN hasn't really had much of a change in Internet speeds. Doing some quick speed tests, it shows that our download caps at around 5Mbit but our uploads are in the 22Mbit range.Thinking Comcast messed up and accidentally flipped our download/upload speeds, I was on the phone with them for almost an hour as we investigated the issue. They finally had me connect directly to the Comcast cable modem to test on my laptop. The results are that from the cable modem, the speeds are correct (I get 22Mbit down, 5Mbit up).
I'm not really sure how to troubleshoot this or where to even begin. At first I thought maybe our PIX couldn't handle the speeds, but it's handling the upload rate just fine. All I know this has to be equipment on our side since Comcast had me test directly from the cable modem.

I recently bought my new Alienware laptop and it would connect to the wifi but no internet. Sometimes it works for a second or 1 minute. Now it's just a triangle with an exclamation mark saying it has no internet access. I already tried the power management. I am using a router; the other laptops in my house is fine. Could it be because the router couldn't support the internet of the Alienware? I remember seeing routers saying "Good for gaming!" something like that. I've been having this problem for 2 days now.

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.

My wireless internet has been acting a bit weird lately. I use a linksys Dual band wireless-N USB adaptor (WUSB600N) to connect to my router, a 2wire 1000sw. I am on windows 7. Recently, the internet has been dropping and reconnecting the connection weirdly; it is apparent in Portal 2 Co-op mode; it says the connection has been lost to the server, and then within 4 seconds, re-joins the server. During that time, the little network icon (the 4 bars in the task bar) says "Identifying."

Basically i'm an employee of a Pro-Gaming team, and as a Job I stream games live, as well as upload game videos to youtube. I've been encountering a problem for a month or so now and had little success of fixing it, which is costing me quite a lot of money and viewers! Basically, I use a program called Xsplit to stream to a website called Twitch.tv (no-one else i've spoken to has the problem I have). I will randomly disconnect/reconnect instantaneously which puts my stream down for 5-10 seconds at a time, then goes back up again. Ultimately the viewing experience is ruined by this and I am on the verge of being replaced!The problem can occur either once a week or once every minute.. it just does it whenever it wants. I have 200mb/10mb internet so my upload should in theory not be an issue.
Things I have tried and done so far:
- Replaced the Ethernet Cables.
- Replaced the Routers.
- Bought a Network Card to try as opposed to my Motherboard port.
- Reformatted my computer and installed a different version of Windows 7 multiple times.
- Spoken to Twitch.tv and Xsplit about their programs as well as used multiple versions of the Xsplit client.
- Spoken to my ISP who say everything is fine.

Router randomly stops working and sometimes reconnects by it self and sometimes I have to manual reset the router. Also I only get 2-3 bars wireless. Is my router not configured properly or damaged?

I have a Netgear N600 (I'm not sure if this is the model number...) and the wireless adapter that was built into my P8Z77-V Pro is an Atheros AR9485. Everything was working fine up until last night, and now I can't seem to connect to anything for more than a couple seconds before it disconnects me again. I should also note that my phone, my iPad, my laptop, and my other PC connect just fine still.

Our internet has been acting strange the last couple days, it will just disconnected for like 5-10 seconds, then come back. Happens anywhere between every couple minutes or every 15-30 seconds. There are two computers on the network, and it happens to both computers at the exact same time.

I've got a brand new C887VA-W-E-K9 that is up and running on a BT VDSL connection. That side of it is fine... But the integrated AP module on it keeps reloading.. I can be on the AP console reading the config via 'sh run' and suddenly it'll be loading the OS again... There's no errors logged, no errors on the console or anything... (I also have yet to get the radio working, it starte dbefore I'd finished the config).
It doesn't seem to be anything I'm doing as if I just leave the console, it'll just sit there... reloading every few minutes... (Although sometimes it seems to stay up for longer).
The console just looks like this. WHich is taken from listing the running config and while sitting at the --more-- prompt... Bang...

Happens every few hours, but is fixed by reconnecting my router. Although this is inconvenient because I run an IRC chat and a small web server. I'm not sure if those would cause such a problem, but I hope not

My internet connection drops every 10-30 minutes and reconnects. The modem seems to reset (every light except the power one). I have a Zoom model 5241 modem. Additionally, I cannot access my modem's status page [URL]. It's as if I'm trying to access a site that doesn't exist. Comcast sent a tech who replaced a splitter, but that didn't work.
