Q: Internet randomly drops for a few seconds then reconnects.

Hello all and thanks in advance for any help.

My problem is that my internet will randomly drop sometimes 1 to 5 times a day and stay off for 5-20 seconds then come back on. I have dsl and im using a Westell modem. I will post some of my system info below. Anything else you need just ask.

Preferred Solution: Internet randomly drops for a few seconds then reconnects.

I recommend downloading and running Reimage. It's a computer repair tool that has been proven to identify and fix many Windows problems with a high level of success.

I've used it in the past to identify and fix everything from blue screens (BSOD's), ActiveX errors, corrupt files and processes, dll/exe/sys errors, recover lost memory, Windows update problems, defragging, malware removal etc.

You can download it direct from this link http://downloadreimage.com/download.php. (This link will automatically start a download of Reimage that you can save to your computer.)

If you mean that the modem is dropping the connection to your ISP, and your ISP supplied the modem, then call their tech support--the problem is all their's unless you have poor phone wiring. Otherwise, what do you mean?

Recently, I switched ISPs from Fios to Comcast and I've been having more consistent issues with my internet on a wired connection. On Fios, the internet was completely stable, but with Comcast the internet randomly drops for a few seconds at a time. It can be fine for hours, then go out 5 times in the next 10 minutes. Just to be clear, when I say the internet drops, all of the lights on the router remain lit indicating the connection is fine, but my computer loses the connection.

With that being said, I'm not sure if it's directly related to switching ISPs. A comcast tech has said that signal levels are fine and the wiring shouldn't be an issue either.

Also, I haven't been able to confirm this, but the issue might be isolated to the computer that is on a wired connection. I can't seem to recall having any issues on devices connected via Wifi. Basically, the connection might be perfectly fine, but something may have happened on my computer recently that has caused these issues. However, I've ran scans to check for viruses, but they have all came back clean.

Are there any troubleshooting steps I can take to narrow down the specific cause of this issue.

Over the past few weeks, I've been getting these connection drops and I've had to reboot my modem in order to get the connection back. Most of the times, the DSL light continuously flashes and I get no connection. If I'm lucky, the DSL light solidifies and I get a dodgy connection for a couple hours and it drops again.

I've been told it's an issue with my attenuation and impulse noise. I've had more than 4 technicians dispatched to my house saying that they've fixed it and stabilized the signals. The most recent fixed the issue where the connection drops for longer periods of times, but the connection is still really dodgy. The connection still drops but not as often and usually happens in mornings.

I'm currently using a C100a modem from Centurylink and if it matters, it's bridged to a Netgear router. Here are my numbers:

That usually means that the modem is connecting to the line
I can not find a manual for that C100a
But the user manual would tell you what to expect from the DSL Light
I would normally expect that to be a solid all the time
You usually also have an internet light , and that one flashes as data is transferring

Hi! I've been trying to search the site for connection issues related to mine. So far I was not able to find one, but if ever this issue has been answered before I would appreciate if someone could send me the link. Thanks!

Here's my problem. I recently installed a linksys wrt210N and is hard wired to our main computer (mac). I have a Toshiba with vista basic and the wireless connection to the internet is working perfectly. But my brother has an Acer Aspire 4520 with vista home premium and his connection keeps dropping every minute if someone is using it and ever 5 mins if its just sitting there. I can ping the router when I am online. Then I tried all these following steps but still the same issue: reinstalling the network adapter; disabling the 802.1... authentication but wasn't able to connect to the router more so I reverted back to the old setting; forced DNS on Internet Protocol Version 4 but getting conflicting IP; dowloading MS update for vista but neither of x64 and x86 version were appropriate for the pc; checked automatic connection on wireless network setting; changed SSID name on linksys. But all these didn't help 1 bit! Please help..... Thanks

A:internet connection drops out and automatically reconnects every minute

The periodicity of the interruption indicates to me that computers on a different, nearby network could be using the same channel as your bro. Through "Device Manager," open up the relevant network adapter, go to Details, select the "Ad Hoc Channel" list item, and it's probably at channel "11." I always have had good luck with "6."

Sometimes a roll-back works: ie, an older driver. I see an Atheros driver Version 7.7.0.363 released around July 2009 that seems to be a pretty generic driver for a very broad range of Atheros wireless network adapters.

So, most of the time my ping (to my ISPs server) is ~15ms, when I upload/download it changes etc., but, I've noticed that when I use the internet I get disconnection spikes (highly noticable when playing League of Legends or doing anything that needs a constant connection). These disconnection spikes happen more frequently when there's an active connection (something's being downloaded/uploaded, eg. a game running).

I have figured out it isn't any of the routers causing the issue with tracert and pinging. (I pinged the first router, the 2nd and then only the IP to my ISP started having issues.)

This didn't always happen, but it does happen on WinXP and Win8 and my Android tablet.

Any tips? (And I know I should contact my ISP, but I like knowing how to deal with stuff myself.)

Thanks. :]

Hey guys, I just wanted to say thanks for taking the time to look at this post. Anyway, I'll get right to the chase, just recently I have purchased the Motorola SB5120 modem and the Linksys WRT546 router, the reason being is because my old modem was extremely out-dated and we needed an easier way to connect my two other computers. All has been working fine until this past week or so, and it seems that my modem just likes to go into a standby state, by itself, from 11 a.m. until 8-9 p.m. central. This will occur regularly about every 5 minutes to an hour for the entire day, the "standby" mode will last for only about 10 seconds, usually just long enough to kick me off from whatever I may be doing at the time. The modem says its working fine though, and even the Cox guy said it was running at optimal performance. At first I believed it to be just some minor difficulties with the network I setup for my family, but that wasn't the case. I've tried resetting everything and just starting from scratch but nothing works. We called the Cox Support team, again, and again, I was told to reset everything. If anyone has any solutions, please let me know. Thank you.

Hey sorry if I mess something up I'm new.

anyway for most of the day my internet has this pattern of dropping out for half a second or longer every few seconds. This happens on all my devices, and the router is only three months old. I've phoned my provider and they seem to think that I'm overloading my internet but that can't be the case as the disconnections are independent to the times that I'm using it. Every once in a while (more rarely) it drops out completely maybe for a minute or two to fifteen or so minutes which I could understand as overloading it, (though I still don't think it is) but there's no way to explain these smaller drops in my internet?..

I've attached a picture of me pinging google which shows the random delays in response. My plan's download speed should be 10mbps.

Thank you very much for the help!

My internet will just drop out briefly so that whatever I am doing on the internet will stop working, for example streaming a video, it will play fine, until two minutes in it stops, I then have to reload the page to continue playing. This happens over and over very regularly until I decide to turn off my computer. The only exception is Skype; I can be in a call with someone whilst playing a video, the video will stop but I am still chatting with the person on Skype.

Although my internet speed is not the greatest it should not just drop out every 2minute interval. It is a home internet so there are various things using it. It is only a recent problem and would love to fix it

If anyone can help it would be great, thank you for your time.

New laptop, connected to my home network which is very stable and has no history of connection issues. After about 10 seconds the laptop drops the connection. Sometimes it'll come back for a while sometimes not, haven't observed any pattern in this yet

All I've done since starting the computer for the first time is installed all the junk that comes with it (Nero stuff mostly) and installed all windows updates (there were over 60 of them) and AVG Free edition. Before doing all that the connection was still not right but it did hold for a lot longer than 10 seconds. It held for over an hour downloading programs like Itunes, AVG and Firefox

Going to control panel > network sharing centre when the connection is down I see the yellow exclamation mark between my computer and my network. Troubleshooting this resets the network adapter, gives me the error 'The default gateway is not available' and says that it is fixed. The connection then works again for about 10 seconds and drops once more.

From setting up the network I think the default gateway is the router IP address?

The internet on the other computers on the network (one desktop one laptop) is fine and uninterrupted

I can't get the connection to hold for long enough to download SysInfo but this is the laptop:

I have an Alienware M14x, Windows 7 and Killer Wireless N1202 Wireless Adapter. My issue is that I'll be on a game server humming along just fine (lets say Minecraft for now) when all of a sudden I notice that I haven't been getting connection for about 7 seconds then. Once its over everythings okay. However, it happens almost once every minute and it lasts for much longer at times resulting in my getting kicked for no response. It doesn't hamper normal browsing but its an obvious pain for gaming. I solved it once before, a while back, but its come back in its original form. I couldn't find the method I used before. All I remember is reading a forum that said to uninstall something from my Device Manager that Windows had added in and once I did it worked beautifully. I think it might have cropped back up in an update or something. But I have tried renewing my IP, turning off power saving on my network adapter, restarting everything, but I can't find that utility to uninstall nor the forum I saw. I could really use some help here...

This problem usually occurs because your router is set to use a wireless channel that is overloaded by your neighbors WIFI connection.

It's best to scan the networks in your area then choose a channel that is furthest away from the ones your neighbors are using. Xirrus WIFI scanner works well for this. You can post the results here if you still aren't sure which channel to choose.

Hi,

Randomly when I'm browsing the internet, my internet goes. Maybe I'm just lucky that it doesn't cut out during an online game.

To get my internet back I just unplug the internet cable at the back of my pc and wait a few seconds and plug it back in again, comes back almost instantly.

I can't ping the router when my internet goes, I check my phone and and can still get internet, no one else complains of it.

I use a TP Powerline adapter. I can not test if that is at fault, no wifi and not too close to the router hence why I use the powerline.



Around the time of internet loss, in the event manager I get messages like these:

Browser: The browser has forced an election on network \Device\NetBT_Tcpip_{F468282B-2F3E-4F03-B32D-7AD58EFD21FA} because a master browser was stopped.

A:Internet only on my pc drops randomly

I am not an expert on this but it looks like the default DNS assignments may be causing the issue.

Have yo hard-set your DNS assignments?

Right click the Network icon on the lower right corner of the screen and left click "Network and sharing."
Click "change adapter settings"
Right click on your network adapter
Select "Properties"
Scroll down to and double-click the "Internet version 4..."
In the dialog at the bottom is shows "Use the following DNS..."
Click "Use the following..."
and set them to point to OpenDNS servers
208.67.222.222
208.67.220.220

You may need to first click "Use the following...IP address" if they grayed out, but you can leave the IP addresses blank.

Click "OK", a few times and see if that helps.

Hello all,

So here's the deal, yesterday I was playing some games on my PC as i'm sure many of us do when my mouse started acting up (it was constantly left clicking when I was holding it down) but I digress, so i grabbed my spare mouse, took the old 1 out of the USB port and popped the new 1 in the same slot. Next to the said USB slot is my wireless adapter (Texet 802.11n USB Wireless LAN card to be exact, some cheap *** 1 i got but it hasn't troubled me thus far) and I must have knocked it or something because my internet just dropped straight away. I thought it would come back up soon after but for the last 20 hours I've been scratching my head and reading forum post after forum post, trying fix after fix but to no avail.

While i'm browsing the web it is usually stable, sometimes drops when I watch Youtube but that isn't the issue. The problem is when I load up online games the moment I hit the play button and it connects to the game server it just dies. I've pinged while doing this and I can see the second I hit play the requests start getting timed out for about 30 seconds, then it will reconnect.

The only game I have gotten to work so far is Minecraft but on other more shall we say demanding games such as World of Warcraft, Final Fantasy 14 and Diablo 3 it just kills it, doesn't even make it to the character selection screen.

I have reinstalled network drivers, bought a wireless usb card, tried troubleshooting everything I can that I know how to do. Any other things I could try?

I can't access any websites on either Internet Explorer or Firefox but MSN and downloads still continue to work.Click to expand...

Fully describe the IE and FF failures to access AND we must assume a connection to MSN is already established before the first IE or FF failure.

Try this sequence as documentation;
get a CMD prompt (run->cmd)
enter nslookup google.com
run MSN and IE/FF until failure
rerun nslookup google.com
If (b) retrurns IP addresses and (d) fails, then your DNS has been changed

I truly hope I can explain this problem and get it resolved. I want to use this as a web server for when I am away from home.

I have a:
Dell Optiplex running win xp pro, sp 3.
intel P4 processor with
1 GB RAM
it's connected with ethernet
to a motorola SB 900 cable modem for
Brighthouse Networks ISP.
I am running DYNDNS updater too, to resolve my dynamic ip to a url.

The problem is that every so often I need to manually obtain an ip address by using the repair button in the Local Area Connection Status window. However, I am able to do the repair remotely, so the nic is working. There doesn't seem to be any event that causes the connection to drop either so I am at a loss.

I sure hope someone knows what is going on and how I can fix this. A web server is kind of worthless if it drops connection. I'm not sure I'll be able to remotely connect if I'm not on the LAN.

Thanks a lot in advance :)

Ever since i've had my laptop it's always been randomly dropping connection and not connecting again until i reset the internet. It won't even connect even if i reset my laptop. It seems to be fine anywhere else i go but i don't use my laptop that much anywhere else. It usually says "no internet. secured." Usually i just go into wifi status then properties and change my channel width from auto to 20mhz only just because it will connect again and stay for a little. It usually doesn't bother me too much except when I game and i need connection to be stable. my driver is up to date and it's definitely my laptop because everything else can connect while my laptop can't

This problem just recently started happening with my computer. I'll be playing a video game or surfing the web or whatever and all of a sudden my wifi connection will drop.

So I'll click the wifi symbol at the bottom right hand corner of the screen to reconnect... but even though it will say that there are connections when I hover over the icon, the list of possible connections will be blank.

I uploaded a screenshot to imgur so you can see for yourself: http://i.imgur.com/qAC5YX1.jpg

I have a Windows 2000 computer that is having trouble connecting wirelessly to the internet. The user connects wirelessly via a network adapter card and due to his desk location, an Ethernet cord can't be used. Several other users are able to connect (including other wireless users) via the small office router (Netgear) and no one else is having a problem except for this one user.

The user has a DLink WDA 2320 desktop network adapter. The adapter continually connects to the network, but after 5-10 seconds, disconnects. Even during the period of connectivity, I am not able to ping the router or any outside web address.

I looked in Device Manager and the wireless network adapter is showing (no question marks or exclamation points), and it says the device is working properly. I went ahead and installed the latest driver for the network adapter and nothing has changed.

I have tried to change the TCP/IP setting from the standard static configuration to DHCP and nothing works. I also went into services and disabled the computer browser. No change. I restarted the Netgear router, just for kicks. No change. My assumption would be that the network adapter is bad. How do I know this for sure, since Device Manager indicates that it is working? Any other suggestions on what I should check? Thanks!

I just built this computer a week or two ago. It's been working fine for the most part except that my network port seems to randomly disconnect on occasion. Sometimes it disconnects and I can't do anything except disable and re-enable it (fixes). Sometimes it says "no internet connectivity" but I am using internet applications without any issues.

This is by far the weirdest bug I have ever encountered with windows and drivers. I am using the Sabertooth x79 Motherboard along with the intel 82579v gigabit ethernet port on it. I have the most up to date drivers from intel's website. I'm not really sure what information you guys need to help me work through this problem. So please request anything you guys feel will help me. Kind of hard to test it out because it happens randomly and may not happen for a day or two.

ISP: RCN

Security: None, had Microsoft Security Essentials running but uninstalled that to see if it was causing an error. Basic Windows Firewall is enabled (although have tested without)

The problem I'm having is the internet on my HP Pavilion Elite HPE-580t PC will drop for these short 10-30 second bursts. After the drop it will automatically start working again. This happens with all programs I'm running on the computer. The odd thing is that it's in a way random. Sometimes I won't get these drops for 30 minutes but then I'll get them every couple minutes.

I've been trying to pinpoint the problem but haven't come up with anything. I tried plugging the computer directly into the cable modem and still had a problem (which I assume ruled out the router as a problem). It also would seem to rule out this being strictly a wireless issue. I removed antivirus (Microsoft Security Essentials) and have tweaked with turning off the firewall completely. I've tweaked the power saving settings to make sure the adapters are not turning off. Even went as far as blanking the hard drive and re-installing the factory settings.

It's worth noting that I have no problems with other devices online. I have a laptop (uses XP) that uses both wireless and a direct connection to the router without issues. An iPad and Xbox 360 has had no drops when in use. This issue only happens with the desktop. The only difference in this device is it uses ... Read more

Hi All,

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).

Give detail explaining your problem - The Automatic Configuration Script checkbox is ticked and the path to the script has been entered however it randomly drops off on some PCs/laptops sometimes and then the users are unable to browse on the Internet. Manually reentering the details temporarily resolves the issue but the the entries have still been known to drop off afterwards. This is extremely annoying especially on remote PCs.

I hope this is a place where i am suppose to post this.

But I have been battling my ISP for 2 years now and just needed a second thought from an outside source. Sometimes randomly my computer will disconnect from the internet for like 3 seconds and reconnect. This give my computer enough time to display the "No Internet" yellow triangle aswell kick me off of any active logged in website.

I have replaced cables, the ISP as came out and replaced my modem and even installed a new cable line into my apartment. But it still happens. I can be just sitting at my desktop reading emails and it happens.

The ISP says it is my computer but I don't think it is because every other device on the network loses internet aswell. The best part is the ISP can't see it on their end.

I just wanted to see if i could pick some peoples brains.

The Issue: My computer which im typing from now (Computer 3 from diagram!) will drop randomly if i browse the internet or am downloading something whilst using the browser.... or sometimes completely randomly for it to then always reconnect by itself after 10-15 seconds.

Also EVERYTIME I restart or log on to my account i will need to restart Router 2 (see diagram) then click the mini comp on toolbar (bottom right) for connections > Open Network and Sharing Centre > Local Area Connection (right side) > Disable > Then Click red "X" and allow windows to sort issue in order for my internet to work on Computer 3!? It will not work unless i do THIS procedure. This happens ONLY on computer 3?

I really appreciate an experienced opinion on helping me rectify this issue!

Recently it started doing it again, and I've searched and searched online and tried literally everything I can find but nothing seems to work. We've updated drivers, tried restore points, changed the driver settings to maximum performance in the power management settings, but to no avail.

We're running on Windows 7, have intel-Centrino Winax adapters. It isn't the router either btw, as we have another laptop that stays connected perfectly fine. Tried toshiba support, but since the warranty is out they wanna charge us, but the tech guy did say something about changing settings, just not sure what settings he was talking abou

Common one this one, but in our case it wasn't a driver issue - it was a DNS issue!

For us, this problem all seems to centre around DNS. Windows 10 seems to occasionally and randomly change which network adaptor it's going to route DNS requests to. For those who don't know - DNS is a system whereby a name like Google gets converted to a unique machine address such as 182.43.11.202. DNS servers are external computers that provide this service. If this service doesn't work properly, you won't be able to browse any websites properly.

One solution if you're using WiFi is to disable your Ethernet adaptor in Windows by going into Control Panel -> Network Connections:



This will force Windows to always use your WiFi connection for DNS requests.

So how about if you use your Local Area Connection for something else - maybe for NAS (Network Attached Storage such as an external hard drive)? My father has such a set-up, with a static IP address at each end, so that he can access shared storage. However for some reason Windows was asking this connection for DNS, which obviously wouldn't work!

(You can confirm this by opening a Windows command window and typing nslookup and pressing Enter. If it shows the IP address of your LAN adaptor instead of the Wireless adaptor, this is what's happening.)

The fix is to go into your Local Area Network adaptor Properties (same menu as shown in the picture above), then go to Internet Protocol Version 4 and click Properties, then ... Read more
