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]

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)

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.

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.

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.

especially when playing online mmo's...sometimes the wireless connection just goes "no internet access", sometimes the internet speed just drops to near nothing (like waiting 30 seconds to load google).i tried to update the driver, that didnt worked...the router isnt the problem since my xp laptop is working fine.i dont know really much about this kind of stuff..so the only solution i have is to reset my router or my wireless adapter and it works..for a certain amount of time.

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).

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.

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.

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.

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?

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.

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.

Default Gateway is not Available. The internet on my laptop only works intermittently. After a minute or so of initial use, it stops working and when I run the troubleshooter it discovers that the default gateway is not available and then it says that it has fixed the problem. However, after only a minute or so more, the internet once again fails. I have tried the "run>cmd>enter>ipcongfig>enter" and found that the numbers for the default gateway are the same on my laptop as for a laptop that does work.

I am connected to a wireless WEP network using a TrendNet wireless adapter running Win 7. The Internet will stop working for some unknown reason only on my PC that uses this wireless adapter, but just web browsing stops working. Skype and Torrent still works. On my MacBook the Internet will still work during these periods.

So normally I re install windows every so often to make sure I am always clear of viruses and stuff like that. Or I just do a bad job of keeping my files organized. Well I re-installed windows on my laptop for the first time(well on this laptop). For some reason my Wi-Fi keeps dropping every so often and isn't able to detect my router. Which is weird because it never did this till I re-installed. Yes, I have the correct drivers and updated ones at that. So I am not sure.

I have a netgear wireless router upstairs. My dell laptop, my iMac (which is downstairs) and my iPad/iPhones all connect anywhere in the house. My Toshiba laptop and my work dell will not connect or it connects very intermittently. I can stay connected for days on other wifi networks, just not at home. Any ideas?

I am using a nokia E66 to connect to the internet at home. My pc at home is running windows 7 home premium 64 bit. I am currently using nokia pc suite 7.1.40.1. All the software installed without any problems. The problem that I am having is that after I connect to the internet, I can only roughly download / upload about 5MB of data and the connection will time out. I do not get any error messages that is did timeout. The only way I know this is that I stop seeing data being transferred in Network properties.
I then open my e-mail client to see If I can connect with a POP account and then I get an error saying it could not connect to the e-mail account. I then have to disconnect and reconnect and try again. This does not seem to affect web browsing though, only when I am downloading files. Like Steam will start update and stop, windows updates will start download and stop and so on.
I initially thought it was a problem with the network operator, but when I boot back in xp (my pc is set up to dual boot between xp and 7) every thing works fine. No download time outs. Is it the nokia software that is not supporting 7 100% yet or am I missing something else?

I was installing a software on my other laptop (it had SQL software with it) and I ran into some trouble as I got error problems that the installation of the software had failed and now whatever I do, I can't access the web! Sure enough, my wireless connection connects successfully and it indicates that I am on the "Internet" but every time I try to use either firefox or internet explorer to go to a web site, it says I don't have a connection.

I am working on a new Windows 7 build and have not been able to get an internet connection on my (MSHOME) LAN.I have a Belkin 4 port router and a DSL modem. Two XP Home computers on my LAN connect OK. The new Windows 7 has problems.After assigning a static IP address of 186.192.2.8 to the Windows 7 computer I can share with the XP computers and sign in on the router. (I have not been able to get Windows 7 to share in the DHCP pool. This inability to obtain a DHCP address also happened on a previous Windows 7 build that I aborted due to mobo issues. Their too I had to assign a static IP address.)AVG Internet Suite firewall network 186.192.2.1 - 2.8 assigned as safe.I get a network picture of the Windows 7 computer connected to an unknown network (public) and a red X between the network and the internet.I tried to rename the unknown network "MSHOME" but have been unable to do so. I did not attempt to make a Windows 7 workgroup as I understand it would not work with this OS mixture.
