Need help with Default Gateway issues

[bullrhino]

On an almost daily basis I will lose my internet connection on my desktop computer and when I go through the trouble shooting process it finally pops up and says something about the Default Gateway being lost or disconnected and then it fixes it and I'm fine for the rest of the day. It appears to happen more often when I'm streaming some video I've found on Facebook, or it's really bad when I'm streaming the weather report from a local news station, but sometimes I'm not streaming anything (that I know of) and just opening a new webpage. This has been going on almost since I got the computer over two years ago and I called HP support and they were not help at all. I do turn my computer off every night. Sometimes I'll go two or three days without an issue, but not very often. It is not my modem or router. I have a laptop and my wife's desktop and other devices such as cell phones and smart TV that are still getting signal when my desktop cannot get a connection so it is clearly just this one desktop which happens to be the one I use all the time. It's not a huge deal but it wastes a little time each day so I'm wondering if anyone knows how to fix it permanently.

Thanks for any assistance.

Open Command Prompt and run ipconfig /all and post the results. Is this a wireless or wired connection?

Go in the ethernet adapter properties, uncheck ipv6, not needed. Check in the power management tab, that is in the Configure button for the Realtek Family Controller in Device Manager, uncheck box says, Allow the computer to turn off this device to save power. Reboot...

Thanks for your suggestions. I've gone in and done what you said, so now I'll watch and see what happens. I'm hoping it works and if so I'll come back in and give you the credit you deserve.

Thanks again.

ipv6 is needed for windows disabling it in Ethernet properties will not disable it, It will still be running in the background. there are a few programs that need ipv6, the first one that comes to mind is Remote Desktop also when ipv6 gains more popularity you may have crippled your computer also any updates to windows are checked with ipv6 turned on so at some point down the road you may break some updates, If I were you I give your Ethernet a static ip of 8.8.8.8 and the secondary one 8.8.4.4

Sorry meant to say change your DNS settings of the Ethernet card to a static IP of 8.8.8.8 and 8.8.4.4

 

[doctore]

If I were you I give your Ethernet a static ip of 8.8.8.8 and the secondary one 8.8.4.4

Those are Google DNS addresses, not sure what you meant by "giving them to the Ethernet".


OP - you said that there are TVs, laptops, etc. connected to the network, but you also said that your PC is wired. Is the entire network wired or is it hybrid with wireless (like a Linksys wi-fi router with ports)?

 

[bullrhino]

doctore, To answer your last question, only my main computer that is having issues is hardwired the rest are all wireless.

Unfortunately the solution offered by DMHolt57 is not working, and based on the comments by sml156 I want to go back and check my IPV6 to turn it back on. The problem is that I don't remember how I got into it to turn it off. Would someone be willing to walk me through that so I can get it back on in case it is ever needed.

Thanks to ALL for your help!

You can recheck the box in the device manager, network adapters, select the properties of the adapter, you will see the box...

 

[bullrhino]

Maybe I'm losing my mind. I remember when I went in previously to follow your instructions there was a box that I unchecked. Now I go into Device Manager and go into the Realtek adapter, which is my only choice, and after clicking on the different tabs I finally tried the advanced tab and there no boxes next to anything, however, there are three lines in there that also have IPV6 in parenthesis and when I click on each of those there is another "window" on the right side that says either enabled or Rx & Tx Enabled. I don't know how I found the box that I unchecked before.

If you follow this tutorial
http://www.sevenforums.com/tutorials/15037-dns-addressing-how-change-windows-7-a.html
Scroll down the page and you will see where the check box for ipv6 is located. It also shows you where to change your DNS

 

[doctore]

You can turn back IPv6 on by right clicking your adapter and checking the box as per screenshot below:

Now, the DHCP problem is certainly not DNS-related, so I wouldn't mess with the DNS settings.

You can assign your computer a static IP address that is outside your router's DCHP scope and avoid DHCP issues, while tracking down the problem (or permanently). Let me know your router model and I can walk you trough it, if you wish.

Btw, are any computers on your network with a static IP? This could be messing with the DHCP, if not done right.

 

[bullrhino]

Thanks doctore. I got my IPV6 box checked again. My router is a Lynksys EA2700. I don't know anything about what a DHCP is and I don't know if there are any computers or other devices on my network with a static IP, and obviously don't know how to find out.

I noticed in some previous posts some were suggesting something about setting something to 8.8.8.8 and 8.8.4.4 but I'm not sure what they were talking about, whether it is a good idea or why or how I would do that.

I really appreciate your help on this!!!

 

[doctore]

Assuming you haven't done any changes to the router - go to your network adapter, open the properties like the previous screenshot I posted, but this time double-click "IPv4" (make sure that you don't uncheck it!). When the new window opens, select "Use the following IP address" and enter it exactly as it appears on the screenshot below. You should be all set.

As far as changing to 8.8.8.8 - you don't need to do it, but I have put in the 8.8.4.4 DNS, just in case.
