Random Wireless Network Dropout
Feb 7, 2013
I have been having intermittent wireless trouble. This includes Ping spiking, Wireless network drop-outs (The network stop appearing on available network list) and packet loss. This is all completely random (though very common) and is frustrating to say the least. As far as I know, the problem is not nearly as bad on other devices in the house , so I suspect that my network card has become shoddy. I have tried updating,removing,and re-installing network drivers to no avail. I have also used cmd and I have pinged 192.168.1.254, which shows random ping spikes, and some packet loss as well.

I have SG200 50/50 Port Switch and the devices that connect into it are servers and workstations
Few days and until we experience network dropouts and when take a look at the switch log it gives me this?

Device connected to gi3 is a Web Server
This is also happening on more ports ie 20-printer, 13-Cisco Wireless Access Point, 24 File Server etc., which I don't know what is going on. With my research, it said something about spanning protocol. Is this possible to disabled?
The other cisco switch where desktop are also connected doesn't have this error.
My firmware is 1.1.0.73
Boot Version 1.0.0.1

Acing some issues with my Belkin router, I can connect to it wirelessly and maintain an Internet connection. Sometimes I notice on my wifi signal symbol in my task bar that the connection closes and reconnects. This doesn't bother me too much, however, after doing that I don't know how many times it will reconnect but the network will not identify, which as you would know that if it cannot identify the network the access is limited and therefore I cannot connect to the Internet. I know it is a long winded problem but I am struggling to find out why this is happening. It is a Belkin f5d8636-4 v2 modem and a tp-link wireless adapter for my pc (achieving a 300mb/s wireless connection)...

Network running about 60 computers, most of which are running windows 7 professional. Some are on a domain, some are not.At (seemingly) random times, some computer on the network will lose the ability to browse websites (including the web interfaces of networked devices). I can't identify what circumstances cause this to occur. I only find out about it when someone calls me.From the affected computer:I can ping sites I can ping our Cyberoam UTM (which acts as our DNS, DHCP, and firewall)disabling/enabling connection doesn't fix the problem releasing/renewing ip doesn't fix the problem flushing dns doesnt fix the problem uninstalled antivirus on two test machines, problem still randomly manifests.replaced the Cyberoam with newer model users have claimed that if they wait a long period of time (40+ minutes) the problem sometimes resolves.rebooting the computer resolves the issue until it randomly occurs again changing the computer's mac address also resolves the issue until it randomly occurs again.

Region : Australia
Model : TL-WR842ND
Hardware Version : V1
Firmware Version : 3.12.24 Build 130110 Rel.58124n
ISP :
The wireless drops out on my router every 1 or 2 days. I checked the LED on the router and it goes off when this occurs.I have attempted to turn WiFi back on using the 'on/off' button on the rear but it still won't work. The only remedy is to pull the power plug for a few moments and plug it back in.

I have a Lenovo T420 with a Intel Centrino Advanced-N 6205 wireless network card that causes me some headache. It randomly gets disconnected from my router (Zyxel P-2601HN-F1) and home network, works fine though if i using cable. Right after it gets disconnected it reconnects and works fine until it gets disconnected again. I have an HP laptop connected at the same time and no problems there.It works fine in the network in our office (work laptop). I tried our IT dept but they were clueless and told me I had to figure it out by myself, as it works in the office..

I've been having some issues with my network connectivity for a while now, and I haven't been able to figure out what the problem is. I run a wired connection to an Ethernet port in the wall of my university dorm. I have verified that it is not a global network issue or an ISP issue; this problem only happens on my PC.My network connection drops/disconnects randomly throughout the day. When I say disconnect/drop, I mean that all attempts to ping or access the internet fail. A few minutes pass before the Network and Sharing center task tray icon shows a warning sign saying that my computer could not connect to the internet.This is temporarily fixed by doing an ipconfig /release and ipconfig /renew, but I have to execute these two commands about 2-3 times a day on average.
There is no exact interval between the disconnects, nor does it happen when I am running particular programs. The disconnect happens regardless of what I am doing at the moment (gaming, browsing the internet, leaving the computer idle).A month back, I installed some Windows Updates and suddenly my internet connection was almost completely broken. I was experiencing the same issue, but much more frequently. My internet would die within 10 seconds of executing any download, but Windows wouldn't recognize that something was wrong. At first I thought the ZoneAlarm, Avast!, or the SafeConnect (as required by my university) services were causing trouble but uninstalling/disabling these services did not fix the problem.I also tried reverting to my default ethernet drivers, which did nothing. I uninstalled and reinstalled multiple versions of my drivers to no avail.However, the internet worked just fine in Safe Mode with Networking, so I cross-referenced the processes/services running in Safe Mode w/ Networking against my normal startup, guessing something else was at play.After some poking around, I discovered that disabling the Server and Browser services permanently fixed the issue of instant connection death. But the initial problem I described still remains;random, less frequent internet connection drops.

At first it seemed to happen everyday at the same time, but now seems completely random (happening twice a day somedays). At some part during the day while the user is busy with this system it drops the network connection. The ONLY way to get it back is by restarting via the reset button. Shutdown or even logoff just hangs. Nothing regarding that card will work or respond, you can not even disable and re-enable. I can however get the wireless to work without restarting. I've done everything I could possible think of including format and re-installing Windows. Something new I've noticed is that the user always has MS Access (in runtime mode) running while network goes down and then you can not end that process.

I have a mix of devices that all access the internet via a Deutches Telkom Speedport W 723v my windows devices, HTC phone and even the iPad 2 never have a problem, but my Macbook Pro (Unibody Late 2008 model) and my iMac (Probably 2007 / 2008) keep having a problem with the network dropping out. To fix it I have to switch off Airport and switch it back on again and it re-connects straight away.The Mac OSX software albeit now rather dated on both devices (The Macbook is 10.5.8) is kept up to date using Software Update.The problem amy also now be affecting my APPLE TV2 it never had a problem before but now I cannot connect to iTunes on my Macbook using Home Sharing it just does not want to connect!!!I did try before going into the Speedport and changing channels from AUTO to channel 1 but that did not resolve it. I am going to do it again and try a different channel but logging onto the Speedport is an absolute pain, I can only login using my Macbook Pro when it is booted into Windows XP and on Ethernet as we had all sorts of problems setting it up and could only do it using IE not SAFARI and now the Speedport login only recognises 1 x PC for logging in, if you try a different device it throws a wobbly and locks up!

My router keeps crashing like it is restarting. it turns off then all the lights are beginning to turn un again after some time it repeats again and again....Last thing they did was turning down the internet speed for our Network. It worked in some time but then it begun crashing again...Then they said it was the cable in the road that could not take all the data stream... And something about and Bit error?I just dont belive the cable in the road thing because our neighbour are running 10 M/bits without a single error anytime... I am not an expert but i've found out that we are running a Sagembox or something like that. The hardware version (if that is important) is: 3DK04-02 Everybody in the house is running Win7 SP.1. If you need any more information then i will try to find them.

I am having an issue with 3 xp pc's in my network loosing connectivity to the file server. There are 4 network drives mapped to a win 2k3 server, when the user logs in everything is fine, after a while the network drives become unreachable and gives the following error - An error accrued while reconnecting (drive letter) to \servershare Microsoft windows network: The local device is already in use The connection has not been restarted” This happens from any user on only 3 boxes. The rest of the network is fine. These 3 are networked via a switch, I swapped that out for another hoping that might fix it, but nothing.
The other odd thing is the same time that the network drives error out it seems that DNS stops resolving anything outside my network. I can still ping the router and other pcs on the LAN but DNS fails to resolve any names for IE, and nothing outside the LAN can be pinged, no Google, no 8.8.8.8. How ever restarting fixes the issue for a short while. There have been no network changes and all systems are fully up to date as far as patches go. I was thinking it's got to be a ether a DNS issue (the file server is also the Active Directory Domain controller) or something in to do with the router/fire wall we use (it's a Cisco ASA 5005).

I keep getting random moderate Nat sometimes, other times its opened. I have made a static Ip and port forwarded 4 ports that xbox uses. 88 udp..3074 both...53 both...80 tcp... Now when i test my connection on the xbox dashboard a message will come up saying make sure my UpNp is enabled, which it is and it tells me to make sure port 3074 is enabled which it is. I have restarted both my modem and router multiple times to try and fix this.
I have a linksys cisco e4200 and I recently updated its firmware which i thought would possibly fix the problem.I have talked to linksys but no luck.I have talked to my internet Cox Communication but they tell me its the router and i believe it is because when i directly connect my xbox to the modem i never get the moderate Nat. I have also talked to Norton about my virus protection because I thought maybe it was blocking some ports, but they disabled it and I still get the message.

I noticed a TON of random devices showing up in my Network within Windows 7. When I say a ton, I mean 739! I am not computer illiterate, but definitely not a pro. My router is WEP password protected, so I'm not sure on earth is going on here. I thought maybe I had a torrent program open that could be affecting this somehow, but I don't..

I have this laptop with a built-in Intel Centrino Advanced-N + Wimax 6250 adapter to connect to WiMAX.Right now I have a WiMAX connection at home with a simple gateway. So what I want to do right now is trying to connect to this network using my built-in adapter.I'm facing right now is that the driver of the adapter only searchs for a certain provider from the US (Clear). I'd like to subscribe to their service but I live in Argentina so that's not a valid option. So my question is if you know of a custom driver or some other way to search for my local wimax network.

Wired PC randomly disconnects from network at random intervals each dayoday it has done so 3 times. The only way I have found to get it working again is to reset the router which can be inconvenient. When it disconnects all wireless devices continue to work and I have no issues like this with my wired consolesI switched to using a static IP address, since having an automatic one gave me the same results [i have since switched back to automatic]Be happy for any suggestions on how to sort this. I am using W7 OS and I'm using an Orange router. I don't know if its relevant, but when I go to reset my router I have noticed that the download light on my router is flashing like crazy when my PC has disconnected.

We have a bunch of computers(70 aprox) connected to a domain. Since couple weeks ago very strange issues started occuring, internet and network access(path to network share is lost) would come up at random times and on different machines and would last for about 10-20 seconds it would re-connect again.All the computers are using private addresses.Most machines are windows 7, some are xp.Using Windows server 2003 as dc.Since the occurance is so random it's very hard to pin point the cause.

I just built a new computer running Windows 7 with an Intel 82579V Gigabit on the motherboard. Since last night while playing an online game, I have occasionally noticed sudden network failures where I either time out of my game or severely lag for 10 seconds before the game catches up.
My other network hardware and setup remains unchanged during this build.I have never had issues with my internet connectivity from my ISP.
The problem is not consistent and I'm not sure how to repeat it. I was playing my online game for several hours and then suddenly started having problems every 5 minutes with disconnecting.I can watch the network utilization in the Windows Task manager drop suddenly and then spike back when I reconnect to the game. Similar visual seen on the Tomato software on my router.
So far I've grabbed the latest drivers for the network chip from my motherboard manufacturer's website and turned off Teredo. I also made sure no power saving features were enabled on the network chip in the device manager.

The problems looks like this: I'm able to browse the web without any problems until at random points of time - might be 2 hours after I turn on my PC or 5 or even half an hour the port 80 gets blocked - actually more like it hangs it self. As whatever I try to open i get "waiting for response" going and going. It's not even returning "page not found" error or anything. To top everything all other ports work fine - i can use https, ping run tracert - no problem there.
I've spend two days looking for some answer on the web but came up empty. I've scanned for malicious software with ad-awar and malwarebyte anit-malware - nothing came up. After restart of the pc everything comes back to normal but its frustrating needing to do that every now and then.
My home network looks like this: I have some broadband modem that is connected to local wifi TP-LINK router (Model No. TL-WR340G/TL-WR340GD). There are four devices using this connection - two pc's (laptops), android phone and android tablet.

We sort of recently got wireless internet, have had it for 2-3 months now I think and everything was running smoothly. Yesterday my internet randomly disconnected and it was only from this (my) pc, the internet was fine for everything else in the house which includes another pc, 3 laptops, cellphones, ipods, and gaming systems. It has been going out randomly since maybe 6pm yesterday. I have to completely restart my computer for it to work again. The only thing I tried was to unplug the modem and router for a bit and plug them back in, which did nothing for my computer lol. When I did that though the other computer had an ip conflict that came up which it's had in the past with my own pc but after I restarted my computer they were both fine. My computer still has random disconnections from the internet though. I don't understand why my computer is the only one affected and why it's starting now when it's been fine for the 2-3 months it's been working.

Our wireless has worked fine over the past couple of years, both mine and my mom's laptops having no problem connecting. We bought Roku not long ago, which connects your tv to the internet so you can use netflix, hulu, etc., and it had no problem connecting. Now, it just stopped connecting. It detects the network but just wont connect to it. The password is right and everything. We also have this problem with an iPod touch, tablet, smartphone, and wii.

This has been a problem for quite a while now, jumping from Shaw to Telus,I have completely exhausted, and I have no idea what's wrong.I live in a household with another family, and we share internet connections, Telus Fiber Optik, as of now. Me and my brother both have our own computer and are connected via wireless adapter, and the other family has one laptop with wireless connection.
The problem would be that randomly, the internet would slow down considerably, with pings going insanely high, like over 9000ms (not joking).At first,I thought I was just too far away from the router.So I moved to a room directly under the router, and the internet was completely fine for around 1 week, then the random ping spikes started to happen again. Now, I've tried tweaking wireless settings, and checking to make sure its just not my wireless adapter, however my brother's adapter is new, but it has the same problem too, so I doubt its the adapters fault.

The 801 AP on my 881W reboots every other day or so, randomly, on its own. The router / AP works great otherwise, no other issues. I checked the error log and I see no indications of why it would be doing this.

I see that many people have the same problem, random disconnects. I am a long term sufferer from this. I have called support before they can't fix it. and being knowledgeable with routers has not worked at all. I turned off every wireless device in the house, even the microwave it still happens. I change the channel countless times it still happens.

I have a problem with my WUSB600N in that it periodically stalls my PC for about twenty seconds. It happens randomly, but particularly when I am using YouTube or playing online games. The symptoms are basically that the screen and process lock up. Sometimes I can continue to move the mouse for a short period, but usually that stops moving too. If I'm playing music in the background (iTunes usually or YouTube) then the music keeps going after the lockup, again only for a short period. Usually about twenty seconds or so later, the whole things recovers. I've tried Alt-Tab or Ctrl-Alt-Del while locked, but that does nothing until the system recovers, at which point i find myself with the Task Manager window or back in Windows, so clearly the keystroke has hit the system normally.
PC is running Windows 7 64, with Avast antivirus, Zonealarm firewall, Malwarebytes antimalware.Its an E6750 on a P5N32E Deluxe with 2G RAM.The wireless access point is about five metres away in a straight line through an open doorway. Signal strength is generally excellent (4 of 5 bars is almost invariably showing whenever I look).I've tried one site which suggested using the RALink drivers instead, but I could not even get that to recognise and activate the WUSB600N, so I'm back with the current (as of today) Linksys drivers straight off their site (18-Jan-10 3.0.10.0). Adhoc 11n disabled, 11h enable, Multimedia/Gaming disable, Radio on/off enable. I've tried with all enabled, but still happens. So I'm back with default configuration.

this had happened for a few months and i did not really mind until the disconnections worsen. usually when i power on the router and started using the internet, it will disconnect randomly once. my wireless SSID will disappear and lost connection. and no matter how i refresh the SSID still won't broadcast.
the only way to get back internet access is to re-power on the router, so the SSID will be broadcasted again.
my wrt54g2 V1 router had recently upgrade to the latest firmware version,1.0.04. but still disconnects as usual. however the disconnections only happens once, after u re-power on the router, you will not disconnect again.
but after turning off my laptop, and use it again after few hours, the same thing will happen again, a random disconnection and got to re-power on the router.

We have about 15-20 APs out in the field, and at random they seem to disassociate from the WLCs and re-associate within a few minutes. We have not looked into that entirely yet, but we are having an issue with a few. Sometimes, they will disassociate and after a few hours reassociate.

I'm having some rather odd issues with my wireless connectivity. Running a draytek 2830n router. The wireless connection drops out at random sometimes, at other times it connects (shows full reception) but does allow any kind of internet connection. Plugging in by lan cable allows normal function.I have no clue whats going on but I did just notice that shutting down one of the laptops connected to the network (Dell lx502) appears to have solved the problem for the moment. I've not had a chance to test this as a long term solution. However I believe this is the only laptop with a dual band wifi card.This problem was also occurring on our previous router, a draytek 2820vn but the symptoms were a bit different and this laptop was not there at the time.Is it possible for one machine to knock out an entire wireless network? The other change I made yesterday was to activate the bind ip to mac function on the router for our new NAS as I was messing around with ftp configurations.

I have a E2500 router that until recently has been working fine, the router currently will reboot at random occasions. I have tried resetting the router to factory defaults to test if the firmware was an issue but both the factory default and the most recent firmware build(1.0.05 build 2) offered on the download support page. I have tried 2 different AC adapters to test power and two different Cat5 cables so hard ware wise everything is looking good. I am concerned that it may be an issue still with firmware or with the cooling fan and the unit may be overheating.

I have a WRT120N, and have set up connections like this:
Desktop PC: Hardwired Ethernet
Laptop: Wireless
Xbox 360 (1): Ethernet
Xbox360 (2): Wireless
Networked Printer: Wireless
The hardwired connections are fine, but at random the Printer, laptop and wireless Xbox connections will drop out and i'll have to reboot the router to get it working again. I've tried everything I know of (i.e., Static IP, Port Forwarding) as well as a factory reset, but I continue to have this issue.

Every now and then my adapter won't be able to connect to the internet for a few minutes, and then it just comes back. This happens frequently, varying from every few minutes to every few hours. If I re-connect the adapter, though, a connection instantly comes back. There's no sign that it's lost connection, the taskbar still displays Internet access and a 5 bars, and the blue light on the adapting keeps flashing; but I just can't connect to the iternet at all.

I have a linksys router and a AE1000 adapter. When I first plugged in the adapter I had internet problems, always had to reconnect it. Then suddenly it worked flawlessly online and in video games. Now youtube videos load slower and I will get random lag spikes in game that last 5-7 seconds. I have done nothing to change the adapter, it just does this out of random.
