Windows 7 64bit - Network Card Keeps Dropping Connection
Dec 17, 2012
My network cards drop the connection and are listed as "unplugged" every time I game online, regardless of the game. I have 2 internal Realtek PCI GBE family controllers on an ABIT IP35Pro mobo. There is no set instance of why/when this happens only that it is completely random and I get the usual Event ID's in the system log after it happens:
The TCP/IP NetBIOS Helper service was successfully sent a stop control.
The reason specified was: 0x40030011 [Operating System: Network Connectivity (Planned)]
The Computer Browser service was successfully sent a stop control.
The reason specified was: 0x40030011 [Operating System: Network Connectivity (Planned)]
There are no other events, Application or Security that happen right before these events other than MS Application experience service entered the stopped state in system log. It could happen every few hours during the day to every 5-10 minutes after midnight( this is what is very weird since it did not do this prior to midnight this many times ). I sit behind a uverse router with it passing through a gateway from 2 powerline adapters. I have no problems downloading torrents, watching movies or anything l else strenuous on the network, but gaming. The only fix I have found is to disable the card and re-enable every time.
I have tried the fixes below with no luck.
1) Disabled Computer Browser service
2) Disabled TCP/Ip Netbios Service
3) Updated Realtek drivers
4) Rolled back Realtek drivers
5) Changed IP address
6) Reset TCP/IP Stack
7) Completely blew out Windows 7 Home and installed a fresh Windows 7 Ultimate I had
8) Disabled windows 7 from shutting these cards off
9) changed power management to never sleep the system

I have seen several OLD posts on the net about Windows 7 64 bit losing connecting with USB external drives, when copying large files...I have also NOT found a resolution.
HP Pavilion e9180t
9 GB RAM
Intel i7 Processor - 920 @ 2.67GHz
Intel X58 Rev 13 Chipset
nVidia GeForce GTS 250 Video adapter
Seagate 1TB Expansion Portable Drive (the drive that is dropping connection)Drive works fine on Vista and Win7 32bit
Note: MS KB97697 patch does not fix, as I do not have an nVidia chipset?

Acer Aspire 7745 Notebook (purchased 10/25/2010)Win 7 HP 64-bit (build 7600) (last update 11/11/2010)Broadcom 802.11n Wireless Adapter (5.60.48.35)Since the last update, the wireless network keeps dropping its connection randomly. Windows Network Diagnostics says it can't connect. Status shows limited connection. Manual disconnect and re-connect says "Not in range" although it shows in the available networks with strong signal. Disable and re-enable causes the entire system to lock up and I have to power down. The only reliable way to reestablish a connection is to reboot or wait some random amount of time until the system decides to recognize the wireless network again.

For the last 3 months my internet keeps dropping in and out, sometimes for a long period of time. But it always shows full bars in the wireless network connection on our computers. I have been on the phone to the internet company for hours and hours (each time speaking to a different person-so no help there) and they can't figure out what is wrong.
They sent me a new modem which worked for 10 mintues and then was dropping in and out again. The same issue is happening on my roommate's computer too, and I am able to access other wireless networks in other locations too with no trouble. So not an issue with our computers.

Windows 7 keeps dropping my connection. It started happening about 3 days ago. Thought I fixed it by turning off my wireless router but it came back. When it happens the connection bar drops from 5 bars to 4. To get it back I have to disable the adapter in the network and sharing center. I'm using a Nexxt Solutions NW230NXT Wireless Router and I have a Atheros AR9285 Wireless Network Adapter.

I have been struggling with my pc dropping internet connection and not seeing the router as well as it freezing at random times, from 5mins use to several hours, but lately its alot more. Its a cyberpower system machine I bought in oct 2008, its had ALOT of use. See below for system specs below please if needed.It will freeze at all sorts of times, does not matter which application I have open. I have to hard reboot. It will also freeze on shutdown sometimes. I get all sorts of errors on connection loss, it will say the default gatway not available, it will ask me to reset my router too. It resets Local Area Connection adapter all the time, when I try to resolve the issue. It also says "Local Area Connection" doesn't have a valid IP configuration, and resets all my settings back to Obtain IP addresses automatically, as well as Obtain DNS server address automatically in the Internet Protocol Version 4 settings. If I put all the IP addresses and default gateway stuff back in without resetting the router, it then says Troubleshooting couldn't find the problem. Resetting the router usually does work. But not always, sometimes I need a restart. It Sometimes it works if I restart, sometimes it still won't see the router.
I tried putting the IP address in as static, put in the subnet mask, and default gateway.I use the Preffered DNS server IP in there as it helps use network gaming and platforms better like SecondLife.I've tested the router network with same cable I use on another laptop so the cable is fine.Changed ASDL filters twice.Bought new router.I've replaced my harddrive.I've tried two different driver versions for my network card which is a Marvell Yukon 88E8056 PCI-E Gigabit Ethernet Controller I've resit my memory.Tried restoring system to a few days before it started freezing again.I've reinstalled windows a few times now, usually it works for a while (week or two) after a fresh new install. Its a fresh new windows 7 I bought as the machine came with vista.I've manually tried to put in all the drivers I need myself as I don't have the disk that came with my machine. (I have no idea if I've done that right)Sent it in for a service clean and checkup.Turned off the option that windows shuts my network driver down to save on power.
SYSTEM SPEC:
(Left out actual IP address numbers from communication, I have no idea if that is safe to forum lol*)

I bought a Netgear wireless router and usb adapter 2 years ago and have not had any problems connecting to the internet until I bought a new computer this week. The only thing I can figure is it has something to do with Windows 7 (my old computer ran Windows XP).
Here is what happens.
1. I plug in the adapter.
2. I connect to the internet
3. After about 30 seconds my connection drops.
Here is what I have done to-date (with no success):
1. Turned off Windows Firewall
2. When in to device properties and turned off option for Windows to turn off device for power savings mode
3. Downloaded and installed most recent driver for device.
What is so puzzling to me is that I can actually connect to the internet for a short period of time. That makes me think the router is alright. Is there something in Windows that would break the connection?

Windows Home Premium 64. my wireless connection drops about twice a day. Sometimes, it takes the wireless router with it. I have a bunch of stuff on the wireless network, but it seems my laptop is the only one causing a problem. My primary card is a intel n-1030, but I've also tried a wireless usb adapter and have the same issue. I have even tried a different router. Same result. updated drivers, flused the DNS.

I have a USB 3.0 that keeps dropping the connection to the devices I try connect to. For example it recognizes my external HDD but then drops it second later. Then it flashes on and off in being recognized. With my wireless keyboard it doesn't recognize it at all.

Since September I've had issues with my internet connection dropping repeatedly. It happens frequently, and everything I've tried to fix it has failed. It's really annoying and I've been trying my best ever since it started happening to fix it. I have a Dell N5110 Computer with an Intel Centrino 1030 Network Card. Here are some things I've tried to fix the problem:
Disabled IP Helper Service
Disabled IPv6
Turned off Power Management settings for my Network Card
Flushed DNS
[code]....
This is the only device on my network that gets any sort of network issue, and the problem seems to be just with Windows 7 as I've heard of people with the same exact setup as me having the same problem, and then reverting to Vista or XP fixed the issue. Also when I use the troubleshooter, it will find the problem and fix it, but the problem will come back. It said the problem was the Default Gateway was unavailable.

I have Desktop A upstairs unto which a wireless router is connected for various devices.Downstairs I have a laptop that I use to connect to the wireless network. I also have Desktop B downstairs. I have an ethernet cable connected from my laptop to Desktop B.There is no drop downstairs so I wanted to connect the desktop somehow. I've enabled the wireless adapter to allow other computers to use its connection to connect to the internet.However, 2-4 times a day the connection simply stops.I don't have any of the computers on Homegroups or anything. All network drivers for all devices (wireless and wired) are updated. Using a Belkin N3000 wireless router.

I've been all over the internet, looking for ways to fix my laptop connection - with no success so far.
I'm simply trying to connect my laptop to my router (they connect perfectly fine and the signal strength is excellent) the only problem I'm having is that the connection is dropping every few minutes, leaving my web browser to continuously load. I've tried connecting other laptops and they work flawlessly, without any issues so I'm really stumped why my brand new, 1600 laptop is giving me so many issues!
System: ASUS G74S Series
Network Adapter: Atheros AR9002WB-1NG Wireless Network Adapter
I've looked at my connection status in Network & Sharing and I noticed that no matter where my laptop is place, it will always remain at 65mbps
Code: C:UsersJordan>IPCONFIG/ALL
Windows IP Configuration
Host Name . . . . . . . . . . . . : Jordan-PC

I am currently at a hotel and am using their wired internet connection. Everything has been working fine until this weekend when I find that the connection keeps dropping out...specifically:
1) Unable to connect when I plug the network cable into computer on startup...have to plug and remove a couple of times till it connects.
2) Connection drops out every 5-10 minutes or so....have to either unplug and replug cable or enable/disable my network adapter on my laptop a couple of times for it to start up again.
3) The connection problem affects random programs but always internet explorer. I can be on yahoo messenger and msn messenger and even an online game and they won't be affected when the connection drops and internet explorer goes out. However, if I log off any of these programs, then I will have a problem getting back on until I repeat the connection methods listed above. Additionally, some IE pages will continue to function for a while if I click the links in them...just cannot access any new pages...
4) sometimes the connection will drop out but it will show that I am still connected in my taskbar at the bottom of my screen.
Everything else on the computer seems to be working fine, wireless also seems to be working too.

Now, I recently had to change to new ISP, that can't provide cable where I live. It's stupid DSL internet through the phone cable. With my old ISP there were zero problems, but now it's quite bad.Connection drops randomly for about a minute, then it comes back without me touching anything. Windows says it cannot connect to the primary DNS server when that happens. The problem happens more in the evening, which leads me to believe I cannot fix it, but any suggestions would be welcome.
Could it be like, not the line overloading because of other people, but the router getting clogged because of being used all the day, or something? O_o There's 4 PCs connected to the same router by the way so traffic gets quite heavy. I can't use my old router. I tried, but the cable that goes in this one is smaller, phone cable, not the ethernet one I plug in my PC.

I have an HP computer, with Windows 7 64-bit, about 4 days ago, my desktop's internet connection will continually drop out and come in ever 30 seconds or less.I have ran norton constantly and ran malawarbyte twice with full scan. My connection allows me to get online, but with the connection constantly dropping, i cant watch any videos because the connection will cut out and when online internet explorer will come up saying cannot display web page. Ive tried google chrome and media firefox and both have the same problem so i know its my connection and can see it dropping at the bottom right of my screen. My router is NVIDIA nForce 10/100 Mbps Ethernet.

I have a D-Link Dir655 connected to a DSL-526B ADSL2 modem. The pair are bridged.This configuration has been running fine for a year.4 days ago I reinstalled windows 7 x64. Now, when I download torrents the connection drops after 15 - 30 minutes, and comes back up 1 - 3 minutes later. When the connection drops it takes the modem connection down; every device connected to the internet drops.When I had reinstalled I upgraded all my programs to the latest versions, but I have since rolled them back to the versions being used prior to reinstalling.The download program is call FreeDownload Manager. It includes a bit torrent client. This have never exhibited any problems before.I also use Malwarebytes with realtime protection, and this blocks various sites. This is typical behaviour, and again has never been a problem.
This time when I resinstalled, I uninstalled WIndows Tablet components, Windows Search and disabled the Program Compatability Service, after reading sites like BlackViper. I have since reinstalled and re-enabled all these features.I also turn of Remote DIfferential Compression, but again, that's been off for many months.

So lately I have been disconnected from the internet every now and then. Usually I just power cycle my modem and router and move on. But today it happened twice so I need to figure out the problem. I powered cycled the modem alone, and I still had no connection. I power cycled the router and I had connection after so I'm assuming it's the router to blame. The router plugs into my modem, and the ethernet cord from the router goes into one of these: Amazon.com: Dynex DX-EHB4 - Hub - 4 ports - Ethernet - 10Base-T - DC power - external: Computers & Accessories. My PC, Xbox and PS3 are all connected to that. Also during this time my iPhone couldn't get internet through WiFi. I have the D-Link DIR-655 as my router.

My internet connection keeps dropping, when I run the diagnostics it comes back showing the problem as the "default gateway is not available" and showing it being fixed, but then it will happen again a few minutes later. I have been Googling the issues in hopes of finding a solution but nothing I have tried from what I've found has worked. My laptop is a Toshiba Satellite L645 and I'm using a wireless connection to a Motorola SBG6580, this is the first time I've had this particular issue since purchasing the computer almost 2 years ago.

I have recently installed windows 7 64, The problem I am getting is that it keeps disconnecting from the internet and when that happens I can not even get to the router by typing in the router address it just hangs.
I have a Nvidia nforce 780i motherboard with latest drivers, i have not installed the network controller manager I have tried disabling the IPv6 and disabled the side scalling in options Also I have given my Pc a static IP address on the network I have also disabled the windows TCP autotuning in CMD
The problem keeps happening sometimes its 30mins or a hour and other times it can be within 5 mins of booting up, to bring back the connection I have to reboot my PC, as disabling then enabling my router/network it still won't connect
I have also tried uninstalling the nvidia network drivers and letting windows 7 install its own but still it drops out, the icon in the tray says internet access but it does not connect to webpages or email.
Also sometime i play a online game and it stays connect i tab out and try a webpage and just hangs , but the online game is still going ?, i close the online game and webpages still dont work

I have had my computer for 3 years and it has worked great, i got a new router bout 4 months ago and it works great. about 2 weeks ago my desktop's connection which is wired, basically stopped working. It lets me get online, but the connection either keeps dropping or just doesnt work. Ive watched my connection and it will disconnect alot and instantly reconnect. I can get online but my page takes half a minute to load, and sometimes it just wont load and say it cannot connect to the web page. I have tried google chrome and media firefox and they dont work either. I have reset modem and router many times and that didnt help even a bit. I have switched routers and that didnt help either. In networking safe mode, my connection is completely stable and it runs fast and loads everything. I have ran norton and malawarebytes many times and my connection is still unstable. I have stwitched ethernet cords too and that didnt help either. I have two labtops and a ps3 and their connection works completely fine so it would just be my computer. Since it runs great in networking mode, it might be hardware but i dont know what. It might not be hardware though because i am nowhere near a computer knowledgable.

I have a problem that is driving me nuts. I upgraded to Win 7 a few weeks ago and since then my wireless connection hasn't worked properly. I have an Alienware M17x (I have installed all the new drivers for Win 7) including updaded chipsets etc. My Wireless network adapter is a Broadcom 802.11n using BCMWL664.sys and vwifibus.sys drivers, connecting to a Belkin F5D7230.
The only way I can get it to work is by uninstalling the network adapter, re-booting the computer, letting the computer re-install the drivers, then manually re-entering the PSK security key for access thru the router then I can get onto the internet. I tried the tech guys at Alienware who said it was a "software" problem and I would have to pay for assistance (i've only had the computer a few weeks) Anyway, there were no help at all.

I have a Dell inspiron mini tower that had some apparently critical either net driver deleted. I'm not entirely sure which driver it was or how to get it back. I've tried downloading a few drivers on another machine and then just transferring them to the bad one but it's not working (3 separate ones now). It was working perfectly before this "thing" was accidentally uninstalled.

It dosent matter if i connect via Homegroup or direct over the network to the files. The speed of transmission between the two computers is about 3-400KB. Sometime, i get about 7-800 KB.
