Windows 7 Intermittently Drops Wired Connection?

May 3, 2011

When I'm disconnected, I lose all connectivity both to the internet and on the local lan, so pinging (for example) Google will time out, but also pinging 192.168.1.1 (the router's lan ip address) will also time out

Fix : Start -> dev manager -> network adapter. Double click, open her up and then under "advanced", take a look at "Link Speed & Duplex".

If this is set to auto-negotiation, try re-setting it to 10 or 100mbps Full Duplex, re-start your computer.

It's the network driver that costs me hours of hunting & searching. MOTHERBOARD : ASUS IPIBL-LB Integrated LAN : Realtek 8111C 10/100/1000 Mb/s (Gigabit Ethernet)

Internet Connection Drops Intermittently

Sep 11, 2011

I'm running Windows 7 x64 and I just reformatted and reinstalled a couple weeks ago. I did this because I was messing around with Linux and removed the partition in the wrong drive...sigh. So anyway, Windows 7 was running rock solid prior to this....no problems whatsoever with anything. So after I reinstall Windows I notice my Internet connection drops once in a while. Some days it doesn't do it at all while others it drops multiple times. It's all up to date too. There are two things different in this install though. The first is I updated my BIOS. I did this because I suddenly couldn't access the BIOS or even use F8 on boot up. The second thing is after you install, Windows wants to update my Atheros (I believe it's called) adapter. I didn't do this with the first install because it was working fine. Ok, so there are the two differences. Do you guys think it's the adapter driver or the BIOS update? [code]

Regular Drops In Wired Internet Connection?

Feb 4, 2013

i'm having an issue where my internet connection will seemingly drop for a split second, and then reconnect.for example, i will be signed into irc and will have a momentary drop in connection which boots me out, and then i will instantly reconnect.another example would be when watching a streamed video (Internet). i will be watching a video and then the buffering would stop, until i manually navigated to a couple of seconds later, and then buffering would continue.a final example would be in skype, where people are constantly getting connect/disconnect notifications from me.i've had a go at pinging google (-t) to see if it sheds any light on the frequency of disconnection. it has an average ping of about 35 ms, and will occasionally spike to roughly 130-150 every 7 lines or so. but other than that it has no difficulty pinging at all.

Internet Access Randomly Drops On Wired & Wireless Connection?

Jul 18, 2012

I've got an older Acer Timeline 4810t running Windows 7. We recently switched from Cox Cable internet to AT&T U-Verse, and I've started noticing that my internet connection will randomly go out when I am connected. This occurs whether I am on a wired or wireless connection. Specifically, I will be browsing the web and, randomly, when I try to pull up a website, I get an error indicating that I cannot connect to that website because I am not connected to the internet. When I check the status of my connection in the bottom right corner, it will show that I am connected to the internet. If I disconnect the ethernet cable (or disconnect and reconnect to the wifi network), the internet service is restored, although it continues to randomly lose connection.

I initially thought that it was a U-Verse issue, so AT&T came out and replaced the router. Unfortunately, I still got the random drops. I then thought it was a Windows issue, so I reformatted by hard drive and reinstalled Windows - still having that issue.My wife has an older Macbook and does not have this problem. We also do not have this problem with any of the tablets or phones that connect to the network wirelessly.I am beyond frustrated and do not know what to do. I also don't know if this is a sign that my laptop is at the end of its life, which would be unfortunate since I've only owned the laptop for about 3 years (my last laptop, a Dell, is on year 7 and still churning).

Wireless Connection Getting Dropped Intermittently With Windows 7?

Nov 2, 2012

I am facing an issue where the wireless connectivity drops intermittently for my Win 7 Home Basic Notebook.Within less then a minute the connection is resumed. Earlier I thought that it was an issue with my service provider.But then I did not face this issue with my Win XP notebook. I mean, both the notebooks are connected and then the wireless connection of Win 7 drops for a minute and then reconnects. During the period when the connection drops, I can still see my SSID, and also checked that the Win XP was connected and I could access the internet.What could be the root cause and the possible solutions for this issue?It is really frustrating when the connection drops when I am downloading big files and I have to start all over.

Remote Desktop Connection Works Intermittently

Feb 11, 2013

I hired a networking person to enable remote desktop connection between 2 computers for me. The computer I am trying to connect to uses a switch to run internet between 2 computers but I only connect to one of those computers. No-ip is set up on the computer I am trying to connect to to standardize the ip addresses and I am connecting using port 3389. What happens when I try and connect is as follows. If I have not connected for many hours (maybe 5 or more) remote desktop connection will not connect. In order for it to work I have to go to my logmein account and log into the computer there first then after logging out of the logmein connection and waiting a couple minutes I can log in using the remote connection fine. Then, for the rest of the day I can use the remote connection with no problems.

In the morning when I try again, it won't connect, I have to go to logmein once again and then it works. I thought maybe it had to do with a power setting so I created my own power profile and set everything to never sleep, hibernate or do anything except run and run at maximum performance...But that didn't affect it, I still can't log in using remote desktop connection after a long wait. I have also looked in the logs for both my Virus software (AVG) and the computer to see if anything sticks out but AVG firewall log stopped logging in November and I can't seem to reset it and the local cpu event logs don't show any issues with remote desktop connection.

My Computer Drops The Internet Connection

Nov 10, 2009

I've been having this problem since I bought this new computer a few weeks ago. It's a HP desktop, the model number is s5229uk and it's Windows 7 Home Premium.

At random times when I'm browsing the internet, sometimes it can be every 10/15 minutes, sometimes just a few times a day it will stop loading and a yellow triangle with an exclamation mark will appear on the connection icon in the bottom right hand corner.

I cannot troubleshoot the problems or open up the network and sharing centre because it either doesn't load at all or freezes, and the only way to reconnect is to hold down the power button as shutting down or restarting fails after about 20 minutes of the shutting down screen.

It's more annoying than anything. I've checked for viruses but nothing came up and the one time it's let me troubleshoot, it's told me to reset the router which I did and it didn't work. I thought it might be a compatibility issue with the router (we use Sky) but some days it works for longer than others.

On the Norton internet history for firewalls and connections I found this which I think might have something to do with it. Does anyone have any ideas how to stop the internet from cutting off because me and my Dad are at a loss, and he's quite good at computers.

Another thing is that it won't let me create a system image by backing it up onto an external hard drive, it gets to a certain point and gives me this message: 'The system cannot find the file specified. (0x80070002) I've tried again and it still doesn't work.

Wireless Connection Suddenly Drops?

Jun 8, 2011

I have an Acer 5532 laptop Windows 7 Home Premium 64 bit. Out of the blue about two weeks ago wireless connectivity started dropping. My wireless bar shows connectivity and full bars. I right click troubleshoot, run it and it resets my wireless connectivity and I'm good to go until the next episode. Sometimes I will be on for an hour with no wireless problem and sometimes I am running troubleshoot every 5-10 minutes. I have searched for solutions but cannot find anything that works. I have an Atheros AR5B93 Wireless network Adapter and have checked for updated drivers and it tells me I am running the latest driver.

D-Link Dir-655 Constant Connection Drops?

May 3, 2010

I'm not sure if this has been posted before, but for the past few weeks, I've been experiencing constant connection drops(I've concluded it that it's the router because both the modem (sb6120) and the router shows the amount of time it's been up) and everytime the connection drops, the router would show that it had just rebooted. Should I reset all my router configurations or is it something else that is the problem?

Computer Drops Internet Connection - Other Devices Do Not

Jun 18, 2011

So I went to my event viewer, and this is what it says whenever it's happened the last couple of times:

Name resolution for the name dns.msftncsi.com timed out after none of the configured DNS servers responded.

The client was unable to validate the following as active DNS server(s) that can service this client. The server(s) may be temporarily unavailable, or may be incorrectly configured. 68.94.156.1

And I went back through older logs of when the same thing would happen, and those two were the ones that popped up the most. However, this also popped up from time to time:

Name resolution for the name www.microsoft.com timed out after none of the configured DNS servers responded.

Name resolution for the name www.australian-charts.com timed out after none of the configured DNS servers responded.

Now, I know my way around a computer, but this internet talk is pure "gibberish" to me, for lack of a better word.

Additional information: The connection to my router is wired, not wireless. My PS3 and my laptop can stay connected/have never dropped a connection, while my desktop does it enough that it's beginning to bother me.

Dynex Gigabit PCI Card - Connection Drops

Nov 3, 2009

I am having networking issues with Windows 7 Pro. I did a clean install on Saturday from Windows XP and started having issues staying/getting connected to the internet with my motherboard's (ASUS A8NVM-CSM) on board Nvidia nForce networking controller. After seeing that others were having the same problem, I bought a new card, Dynex Gigabit PCI Card which installed perfectly and disabled the other one. Now I'm running into issues of my connection dropping sometimes every 5, 10, 20 minutes and the only way to get it back instantly is to do ipconfig /renew.

When I do the troubleshooter, it tells me there's something wrong with the connectivity of my modem or router, which is impossible. I say this because I live with roommates who are all using different operating systems (Vista, XP, Mac OS X Leopard) and they haven't had connection problems either. There are two routers in the house, a Netgear and a Cisco, and I haven't a problems with either of those when I was on XP, and my roommates aren't having issues with it either.

Any ideas or settings I might be able to change on this card? I've tried drivers and changing cables out, making sure Windows doesn't turn off the network card to save power...etc. Let me know if you need more information.

Wired Internet Connection Working With XP, But Not Windows 7?

Oct 4, 2012

My Dell Dimension C521 died on me maybe 6 months ago. It has Windows XP on it.

I put it to the side and bought a HP Pavilion G7 laptop to replace it with, which came with Windows 7 Home Premium. From what I remember I just plugged my ethernet cable into it at the time, and I was able to use my Virgin Media connection straight away, didn't have any problems.

So last week I finally repaired the old Dell and I've been using it for about a week now, while the new laptop sat unused in the other room. Now, today when I try to use the laptop again to connect to the internet, it doesn't want to play ball; troubleshooting the connection comes up with 'The default gateway is not available'.

I didn't change anything or do anything, I just didn't use it for a week and now it won't connect to the internet. The only difference I can see is one machine is XP and one is Windows 7...

I used the Windows 7 recovery disc to reinstall the OS hoping that would fix it (after a few system restores failed to address it), but no luck. When I ping my default gateway as it's shown in ipconfig, it comes back 'Request timed out' 3 times, then 'Destination host unreachable'.

"Tunnel adaptor 6T04 Adaptor: cable.virginmedia.net" doesn't have a Default Gateway listed, is this somehow relevant?

Windows 7 Keeps Disconnecting Hard Wired Internet Connection?

Jan 31, 2011

I have all of my computers (4 of them) hard wired into the router. Then the other day my step-daughter needed to print something out from her computer that had a program on it that mine did not have and my computer is the only one with a printer (the kids 10 and she'll print out anything). So I created a home network so I could enable printer sharing and then the problems started.Now the internet on my machine and my machine only keeps losing my internet connection only when I wake up this machine from sleep mode (I guess it is going into to sleep mode) It is fine when I first turn it on in the morning (because of this problem I can longer just keep it on all the time - I have to shut it down at night). Anyway, if I walk away from my machine for a period of time, when I come back and wake it up it loses the internet connection and then everything is slow. So I have to shut it down and then when I restart it - everything is fine!

WiFi Connection Occasionally Drops / Only Re-connect When Restart Router

Jul 1, 2012

Generally once or twice a day, my computer will suddenly drop its internet connection.It will then start an endless loop of trying to connect: Sensing the network is there Trying to connect (With the loading symbol and "Initializing")Appearing to connect successfully (but when I try an open a web page, nothing loads, and I receive an error message telling me there's no connection)A few seconds later, the yellow triangular warning sign appears next to the wireless bar.A few seconds after that, it drops the connection, and then starts over at step oneA few seconds later, it will start again at step one.The only way I am able to get the network back on is to: Disconnect manually (press "disconnect")Turn of my wireless antenna on my computer Turn on and off my router Turn back on the antenna Reconnect.I have to do these 5 steps every time it disconnects.This is only happening on this one computer - other computers on the network aren't experiencing the problem (running XP and Win 7).I have an Asus U56E-BAL7.

Cannot Use Wired Ethernet Connection

Jul 23, 2012

Recently the power went out in my house. Ever since the power has come back on, I haven't been able to use my wired internet connection. When I look at my devices, my Intel 82566 Gigabit Network Connection has the status "This device is not working properly because Windows cannot load the drivers required for this device." I've tried re-installing and updating the driver, but I can't tell whether I've done this successfully. In any event, it still doesn't work.

I have a Dell XPS 410. Let me know if you need any other information.

No Wired Connection To PC - Getting Yellow Icon

Jul 6, 2011

I have AT&T U-Verse with a 2Wire (3801 HGV) router. I've had the service for about a month without any issues. As of now, I am able to connect to the internet using WiFi (via my Wii, iPhone, and Laptop), but when trying to make a WIRED connection (via ethernet cable from the 2wire router directly to the PC), all I get is a yellow icon.

If I unplug the ethernet cable and plug it back it, the blue circle appears for a while, then back to the yellow error icon. In the Network and Sharing Center, I am showing my PC with a broken connection (yellow triangle) to "Unidentified Network with a broken "red X" connection the Internet. I thought maybe it was the ethernet cable, so I tried a wired connection from the router to my laptop (also running Windows 7) and it works just fine, so I've determined it must have something to do with the PC itself.

I've tried doing a system rollback, resetting the router itself, made sure the network driver on the PC was up to date and ran the test to make sure it's working properly.....all with no luck. I've tried using Windows to diagnose the problem and I get "Problems Found: Local Area Connection doesn't have a valid IP configuration". What baffles me is it was working fine up until a few days ago.

Wired Internet Connection Keeps Dropping Out

Jul 1, 2012

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.

Lost Wired Network Connection Overnight

Aug 19, 2012

I have two PCs cabled directly to a Netgear WNDR4500 router. This morning, my Windows 7 PC had no network connection when I turned it on. These computers don't get moved, I wasn't messing with the cables beforehand. Everything was fine yesterday.The Troubleshooter suggested I had a broken cable. I tried another cable, but it still would not work. I connected the Windows 7 machine to the same router connection my XP machine uses, but it still did not work.Device Manager reports the Network Adapter is working properly. The system tray network icon reports "Not connected/No connections are available." The Troubleshooter reports, "A network cable is not properly plugged in or may be broken." I tried disabling/enabling the Local Area Connection, but it still reports "Network cable unplugged." My gut feeling is that the Ethernet jack on the motherboard is physically broken. But it blows my mind that it would break for no reason.Could an automatic update of some sort disabled networking in a way that it only appears the cable is bad? Could the physical connection at the back of the machine spontaneously break? I suppose I could go buy a network card, which would be cheaper than replacing the motherboard. I'm gonna get cleaned up and head to the store now.

I have been trying to set up a router at my girlfriend's apartment. I first tried a Linksys router that I had brought from home. I hooked it up from the wall port, to the router, to my computer. I was able to access the normal Linksys wireless setup page at 192.168.0.1 and set up a network fine. I then unplugged my ethernet cable and attempted to connect to the network and was not able to. If I recall, it 'connected' but there was no internet connection.

Samsung Netbook N102S Not Picking Up Wired Connection?

Aug 16, 2012

i recently bought a samsung n102s netbook. It came with windows 7 starter on it, on which wired and wireless connections worked fine. Then I installed windows 7 professional, on which I could get a wired connection, but only a very slow wireless one. Now, I've replaced professional with Windows 7 Ultimate, and my wireless connection works fine, but I can't get a wired connection. When I plug an ethernet cable in, the icon in the system tray doesn't change to the square "wired connection" one, it just stays with the wireless one. The "wired connection" icon appears briefly during startup, only to be replaced again by the wireless one.I've tried to update the drivers for the ethernet controller, which is type Realtek PCIe FE Family Controller, but to no avail; the wired connection is not picked up.

Wired Ethernet Connection Unstable, Dropping Every 5 Sec And Reconnects

Mar 27, 2012

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.

Disable Internet On Wired Connection But Still See Network Computers

Jun 16, 2010

The wireless is one I share with my roommates and is fast. The wired NIC connects to a router which has slower internet. The reason I connect to the wired router is so my PC can talk to a linux machine, which I use for some data downloading/analysis.I want to disable internet from the wired connection but keep the ability to talk to other machines on the wired network. I just changed the IPv4 settings and deleted the DNS server information. Is this the best way to do so? I want the wireless to provide internet.
