Internet connection drops every 30 minutes

I'm chasing a frustrating problem on one of our HP laptops.

The laptop loses its internet connection after 30 to 60 minutes, and the only way to get it back is to restart the PC.

The PC is a dv6 Pavilion with Intel Core i5 processor chip.

Operating system is Win7 Home Premium SP1

Network adapters that I show are:

Intel WiFi Link 1000 BGN

Microsoft Virtual WiFi Miniport Adapter

Microsoft Virtual WiFi Miniport Adapter #2

Realtek PCIe GBE Family Controller

Antivirus is MS Security Essentials

Router is a Cisco/Linksys E1500

The modem is Actiontec M1000

Is DSL through Qwest

The error message we get when internet stop working, said something about "cannot find DNS", I will copy it down the next time it happens.

The PC only to lose the connection is this.

Reset the modem and the router not to find an internet connection.

The problem occurs if the PC is connected via a cable or wireless

When the PC loses the internet connection I can still see and ping it to other PC, and you can still see the other PC.

Here's what we've done so far without success:

Run the Network Diagnostics can not find the question

Router and modem reset

Reset TCP/IP and restarted (netsh int ip reset c:\resetlog.txt)

Off the hidden network adapters:

6to4 MS card

Map of ISATAP MS 1-4

Teredo Tunneling Pseudo-Interface

(all these returned when we restarted)

Change DNS servers on the local network, Wi - Fi and on different servers

Change the DNS from the router to the same servers 2 servers

Restored the PC on 2 previous restore points

Update Intel WiFi driver

Don't scan last Antimalwarebytes - no problems found

Turned off the firewall

Removed McAfee (hate this stupid show)

I am at a loss what to do next.   Any ideas?

We try to be methodical obviously, starting with the simple and more complex.

Thank you!

    Hi all!

    4 months I suffer from this problem.

    My internet connection drops every 15 minutes and takes about 2-3 minutes to reconnect.

    In the meantime the wifi connection still works and strong (5 bars).

    I tried all methods to resolve this problem, dns flush, back, ip address, update driver... I have even to connect my laptop to a dongle wireless usb to see if it's a hardware problem, but same result. I tried to connect to another wifi network but also the problem remains.

    Strangely when I connect my computer to my phone internet of the data over wifi it works perfectly.

    My phone, iPad are connected to the wifi in my house without any problem.

    Any idea? Thank you very much in advance for your help.

  • L755 satellite internet connection drops but stilll connected to the network

    Hello

    I hope one of you can help me. I have a laptop 13 q Satellite L755 nice for a year and a half.

    My problem is that I surf the net and suddenly my internet connection drops down. On Firefox or IE, I have a message with a triangular signal yellow saying: "your connection has be revived."
    I'm still waiting on my network but I can't access the internet.

    The strangness, is that my family other PC or laptop have no problem on the connection.
    This happens on the wifi and cable. At home or other places of connection.
    In France and the United States. So my conclusion is that there is a problem with my laptop.

    I looked around some forums. It seems that some have a problem with IPv6.
    I have disabled the option to use IPv6 on my laptop, but I still have the problem.

    Another comment: I play the Kingdom of the fortress online.
    Sometimes I disconnect from this game but I can still surf the internet for a few minutes before undergoing a total disconnection.

    Looking forward for your help.

    As this happens using WLan and LAN its really hard to say why your connection is interrupted.
    Have you tested the internet connection with fresh preinstalled system?
    I mean it is possible that some software / updates received or installed in the past it would affect.

  • Internet connection drops

    The OS is El Capitan 10.11.3 on both my MacBook Mid 2010 2.4 GHz Intel Core 2 Duo 8 GB 1067 MHz DDR & iMac 21.7 end 2012 2.9 GHz Intel Core i5 8 BG 1600 MHz DDR3, connection to the internet with the 5th generation Airport Extreme. The internet connection drops without model except that diagnosis shows a cable ethernet disconnected between the Airport Extreme and the ISP modem. I can install an older Airport Extreme I replaced about 4 years ago because there was no support for WPA security with the same Ethernet cable and the connection does not fall. I can also plug the MacBook with the power cord and connect via Ethernet. Is it possible that the Ethernet WAN port for the modem to ISP is down? The reason why I ask is that I install the older airport with the same ethernet cable. (I have other cat5 cables, but none of them are cross-cable as the cable provider ISP) I don't want to leave the network upward with the old airport because I have no security.  I price a new Airport Extreme and a cable crossed, but I'd feel better spending the money if I can be pretty sure that the 5th generation extreme is a failure. Anyone have any ideas?

    Some modems are more problematic that others... you must tell us the details.

    This modem you have, make and model please?

    You don't show us the summary for the AE, but if you run 7.6.4 firmware, it is less stable with some modems than previous 7.6.1 (this is why the old AE does not fall).

    Please firmware downgrade to the AE to 7.6.1. For this, hold down the option key while clicking on the version number of the existing firmware. A list... Select 7.6.1 (DO NOT USE 7.6.3. it is poor..).

    The latest version of AC AE is even worse... so I recommend you to buy a different brand of router... you can continue to use EI as WAP, as long as you take on their track, it should work ok.

  • Internet connection drops when I turn on the laptop

    I use a computer laptop dv7-7250us HP Envy, running windows 8.1.  All my software is up-to-date.  In the last month, everytime I turn on the laptop, the internet connection drops.  Troubleshooting of HP operation resets the wifi adapter.  It's boring run the troubleshooter in the mornings.  Any suggestions on what I can to prevent that from happening.

  • My internet quality drops every 5 seconds - 3 minutes for 1 to 5 seconds while playing games.

    * Original title: quality Internet stutters?

    The problem:

    My internet quality drops all the 5 seconds - 3 minutes for 1 to 5 seconds and I have no idea if this is my system, my router, my card or my internet provider. It is to play games almost impossible.

    You can see dips in connection on the chart on the attached photo.

    Complete test results: http://www.speedtest.net/my-result/3591022597

    Info:

    My current provider is Xfininty (Comcast Cable) and we have a bunch of 25Mbps (it's what I think it is.).

    My current router is the "double AC1900 - router Linksys band SMART Wi - Fi" and the card to go with it is the Linksys AC1200-free wire-USB AC adapter ("Linkysys WUSB6300" in the Device Manager) and "Rocketfish USB 3.0 PCI Express Card" for the adapter to be used for my computer. I need the adapter so I can access the two Wi - Fi signals, the router clears.

    |-------------------------------------|

    My System Specs are as follows:

    Processor: Intel (r) Core S 860 @ 2.53 GHz 2.53 GHz

    Installed memory (RAM): 8.00 GB

    System type: 64-bit Operating System

    Graphics card: NVIDIA GeForce GT440

    |-----------------------------------------------|

    Other info:

    I used to have an old router a NetGear, and there was the same problem, but with a slow connection constantly. We have since then replaced by the current one and that did not help, wait for the best connection. I found a new router would fix it, but it didn't. This is why I think it's my system or my internet provider.

    My router is in the basement and I am on the 2nd floor of my house, but that has not affected all the world, so I don't think it affected me. Other dips in the connection, the quality was great and constant.

    What I tried:

    I contacted Xfinity and chatted with an agent and described the problem I did here, and they said that nothing was wrong, on their side, as they watched it. A friend suggested may have my system. In this case, I made sure everything is up to date, and I believe that it is.

    All the cables that are used for the router are correctly connected.

    Reasons:

    -Why I think this is my System: offset varies in different games. For some games, my ping will increase and it will be a "big shift" and the shift happens from time to time, rarely, while for the other games it will lag very frequently, it will be a "small shift", while there will be no change in the ping.

    -Why I think it's my internet provider: even if I got a new router and adapter, there are always these tips little lag as it did before.

    ----------

    For me, it's quite confusing, because there are reasons pointing in all sorts of directions and I don't have no idea what direction to go. I tried as much as I can, although apparently not liked very much.

    ----------

    Thanks for reading and thanks for helping if you do.

    Hello

    Thanks for the reply. I was talking about the pre-installed games that I was online with like Team Fortress 2 and League of Legends. But due to another question earlier about another problem, I deleted Norton Security Suite and who seemed to have it fixed. I just hope that is not temporary.

  • Windows 7 - Internet connection drops regularly

    Howdy

    OK, let's start first. I widely studied this issue, nothing works, is a lot of people saw it and this is not unique to the computer of the person.

    The question. I have a Mac Book Pro and it has bootcamp on it, that allows me to partition and run in native mode, Windows 7. Once again, this problem arose for both users of bootcamp and not. When using my Mac, I am able to use both wireless and Ethernet for the internet, no problem. When I'm on Win 7, I lose my internet connection sporadically. If I was on average, about once every 90 minutes or more. It does not matter that I use LAN or wireless, the same incident rate. The error is still the same, I got an IP address not valid. I run the built in Explorer to fix the internet connection tool, he immediately restores then connection and then I'm good for another 90 minutes or more.

    I have to use Bootcamp for some projects client and when Im in the middle of such collaboration and Im suddenly started because of internet fall, its super frustrating. There is a lot of info about it on the internet, but no real solution permanent. Help, please.

    Thank you

    B

    I found an article that seems to fix the problem, we'll see. I forgot the exact names of things, but I had to go where all network connections and disable everything except the LAN line, there were three against one. Then, I went in the LAN settings and uncheck something in the direction of version 6? It was a box that I simply disabled. I was able to run several hours without a drop, more stable later today.

    Thanks for the reply.

  • Problem with my internet connection drop.

    I keep losing internet connection on my laptop Toshiba, he usually drops about 14:00 every day and I reconnect and on 5 minutes later, I lose again, I have two other laptops that do not have this, it's only this one and this one is new, I throw the bad shoots and he tells me that the default gateway is not available fixed. But then 5 minutes later it happens again. Can someone help me? I had this problem for months, I could use the help. Thank you.

    Hi Mike,.
    Thanks for the reply.

    Sorry I know this previous method suggested did not help.
    I suggest you to reset TCP/IP and check.
     
    Manually assign the IP address and the default gateway and check if it works very well. Before assigning the IP address and the default gateway manually, make a note of the IP address on the computer. To do this open command prompt, type ipconfig and press to enter. This displays the IP address, make a note of it.

    To manually assign the IP address and default gateway, follow these steps:

    a. in the system, right click on network icon tray. Choose the open network and sharing.
    b. right-click on the connection to the Local network and click Properties.
    c. double-click Protocol Internet Version 4 (TCP/IPv4) and assign the IP address manually.
    Example: Old Ip address is 192.168.0.1
    Replace the IP 192.168.0.50
    d. let the subnet mask and default gateway are the same.
    Subnet mask = 255.255.255.0
    Gateway by default, would usually 192.168.0.1 or 192.168.1.1
    e. click apply then click Ok and restart the computer and check if it helps to solve the problem.
     
    I hope this helps.

    Hello

    This problem can be caused by damaged or incompatible network drivers or third-party antivirus blocks. I suggest that disable you the antivirus and check also refer to article assistance and update the network drivers and check if it helps.

    Step 1:

    Disable the antivirus software and check if it makes a difference.

    http://Windows.Microsoft.com/en-us/Windows-Vista/disable-antivirus-software

    Note: Antivirus software can help protect your computer against viruses and other security threats. In most cases, you should not disable your antivirus software. If you do not disable temporarily to install other software, you must reactivate as soon as you are finished. If you are connected to the Internet or a network during the time that your antivirus software is disabled, your computer is vulnerable to attacks.

    Step 2:

    Updated network adapter and check if it helps. See step 4:

  • Internet s DC every 30 minutes - 1 hour for just a few seconds

    Hey everybody.

    I recently had a problem since I reformatted my computer about two months ago.  It happens randomly, most of the time on every 30 minutes to an hour and disconnection only lasts a few seconds and will automatically reconnect. I'm the only computer using this router. My router is a newer router with a built-in modem. I am direct connecting the router/modem for my computer.
    At first I thought the network card on my motherboard was just going bad, so I bought a well known & reviewed internet card. Has worked for a week, now same problem. I tried ipconfig/release, /renew/ and / flushdns - still dc.
    The only other thing I know to try replace the ethernet cable, but I didn't yet. So if you guys have any possible solutions I'd love to try them. Looks like I can't play a game without worrying about dying during disconnection.
    Thank you!
    Cody v.

  • Intermittent problem with IP addresses and internet connections dropped

    Once a day or so my PC (Win7) will not be able to access the internet. Connection just drops. I use DHCP for IP addresses.

    As far as I can see in the Event Viewer I get these types of errors "the address lease IP 192.168.1.64 for the network card with network 0x406186808C4C address was rejected by the 192.168.0.1 DHCP server (the DHCP server sent a DHCPNACK message)."

    My local network is simply: PC-online router (Cisco E1200)-online internet (modem Siemens SpeedStream 4100 DSL)

    "When this happens, we run ' ipconfig - release 'then' ipconfig - renew." This usually fixes the problem. Sometimes, this does not solve the problem, and we need also the modem power cycle. In a few minutes find us the internet connection. It's nice to have a manual correction, but we want to solve this problem to happen... as is the engine of our family crazy...

    The address LAN IP of the modem is set to 192.168.0.1

    The address LAN IP of the router is set to 192.168.2.1

    When things are running OK, I usually see it in the ' ipconfig-all the ' results: = 192.168.2.147 IPv4 address (Preferred) [but the IP numbers change slightly] my understanding is that see "Present" in the result is a good thing (but I don't know why...).

    Any thoughts on what is happening? and how to permanently solve this problem?

    I'm also confused on IPv4 and IPv6. Should I be concerned with any information of IPv6 in the ipconfig-all the results?

    Thanks for the help

    Talked with the ISP (ATT). Zig - zag, you were on the problem. I had both modem and router set to DHCP mode... so I had some conflicts. The solution was to define the "bridge mode" dsl modem and configure the router to "PPPoE mode. Everything works now. Thanks for your help.

  • Canning Internet connection drops when the computer is connected to the PS3 via an Ethernet cable.

    Original title: Shared network problem

    I am trying to use a shared network, configure as follows. My computer connect wireless to my router. My PS3, however, seems to be really slow when connecting wireless to the router and is at a proper speed when connected via ethernet. So, I have my PS3 connected to my computer with an ethernet cable. I put the wifi connection to be shared. Next, I set up my PS3 to connect to cable internet. Has gone through the steps and connected properly and at full speed too. However, there is a problem. My PC guard 'give up' connection to my router, while remaining connected to the PS3. I have to manually connect to my router again, regardless of the connection automatically option. Almost as if my PC is to use ethernet for internet access, (which he won't get that which is connected to the PS3) and so it loses the wifi connection. This abandonment happens around every 5 minutes or more.

    Is it possible to keep my PC connected to my wireless router and still be connected to my PS3 through ethernet to connect my PS3 using my PC?

    The problem seems to have 'fixed itself. I tried messing around with the connections that would not work even the bridge. Then I've switched back to ICS and did not have a disconnect since then.

    So the problem is now resolved, but don't know how?
    Whatever it is, I am very grateful for your help Manasa, it is well appreciated!
