L ike many PC users and avid gamers, last week I purchased and installed Windows 7. This new operating system from Microsoft was supposed to have fixed many of the stability problems encountered with Vista.
Within minutes of upgrading my Vista 64-bit version of Windows to Windows 7, I started losing my connection to the Internet approximately 30-60 minutes. For no apparent reason, my computer which was attached to the Internet via a D-Link Gamerlounge router would drop it s connection while the other computer running Windows XP hooked up to the very same router enjoyed uninterrupted Internet service.
I would get the following message when I hovered over the Internet/Network: the default gateway is not available. Each time I would right click on the connection icon and select the Troubleshoot Options it would eventually repair the problem and reconnect to the Internet.
Here s a possible fix I found for this on the Sevenforums.com forums:
Press the Start Button.
Select the Control Panel.
Under Network and Internet select View Network Status and Tasks.
In the View your Connections section, click on Your Local Area Connection which will bring up a new window .
Click on Properties.
Uncheck the box on the same line as Internet Protocol Version 6 (TCP/IPv6).
Click Ok, then click Close.
Welcome back to uninterrupted connection to the Internet!
Update: A few days after posting this article I started getting disconnections again. I noticed that it was during large file downloads. I had purchased an album on iTunes and during the course of the download my internet connection was getting dropped. I have found an additional fix that has seemingly solved the problem. Go to your Device Manager, then go to your network adapter click on properties, then click on configure. You should see an advanced tab now; scroll down till you see the property receive side scaling. Now on the left side you ll see a value box, make sure it is set to disabled for this property. Hope this helps!

After WEEKS of having my internet connection unavailable after my Win 7/Dell computer woke up from sleep/hibernate, I have found a solution.
I read several places about the duplex/network speed configure function for the ethernet router being set to Auto negotiation . Then I read that my network card duplex/network speed may also have the same setting.
I figured that if both the router and the NIC were trying to auto set, and neither was set to a specific speed that setting one to a hard setting might solve the issue.
I set my NIC this way in Windows 7:
2. Type Device Manager , press enter or double click the entry for DM
3. Scroll down to Network Adapters and expand the tree
4. Right-click your network card and select Properties
5. Select the Advanced tab and scroll down to Link Speed Duplex
6. The Value on the right is probably set to Auto Negotiation ,
change it to 100Mbs Full Duplex or whatever is the maximum speed
of your network card.
7. Click OK , close Device Manager and reboot.
I made this change about 2 weeks ago. I am pleased to report that since doing so, my Win 7 box now resumes from sleep and the internet connection hasn t been down once.
I sincerely hope this helps others to fix the same frustrating issue with their connection.
I have tried for 2 years to fix this intermittent internet connection. I d have to unplug my ethernet cable from the wall, then plug it back in about 15 times a day. I FINALLY SOLVED THE PROBLEM. It wasn t Windows 7, it was AVG Free, my antivirus! I went into add/remove programs and deleted AVG Free, then I downloaded Avast Free instead. I also went into Control Panel, then Performance Information and Tools, the Adjust Power Settings and made it where it s high performance and can t do any power saving. Deactivated screen saver powering down, etc. Then from start menu, type device manager, click on network adapter , then click on your adapter, then go into Power Management and make sure all are unchecked (f you are not using a laptop). I also went somewhere else (can t find it now) and changed my setting from the computer deciding on the setting, to changing it to 100 mps. I have not lost a connection in 3 whole days! I believe the MAIN problem was the AVG free conflicting with Windows 7. Maybe you won t even have to do the other fixes that I mentioned, but if you have any intermittent problems after loading Avast, then try those fixes too.

I had this problem for the last three months and used all fixes listed here with no luck. I finally found what the problem was. One of the drivers in your network adaptor card begins to go bad and it sends a signal tells it to go to sleep to save power. Follow these directions below.
The Allow the computer to turn off this device to save power setting controls how the network card is handled when the computer enters sleep and can be used if a driver misrepresents how it handles sleep states. Windows never turns off the network card due to inactivity. When this setting is checked(enabled), Windows puts the network card to sleep and when it resumes it puts it back to D0. When this setting is not checked(disabled), Windows completely halts the device and on resume reinitializes it. This setting is useful if a network card driver says it supports going to different sleep states and back to D0 but it ultimately doesn’t support this functionality.You can use Device Manager to change the power management settings for a network adapter. To disable this setting in Device Manager, expand Network Adapters, right-click the adapter, click Properties, click the Power Management tab, and then clear the Allow the computer to turn off this device to save power check box.
In Windows 7 or Windows Server 2008 R2, you have two additional check boxes on the Power Management tab for the Network Adapter that defines whether this device can wake the computer: After you check card and click ok. back out by closing all that you opened, then you must reboot. If you don t reboot the card will recheck itself leaving you with the same problem. Hope this solves your problem !

Thanks for this fix ,it worked for me. This problem was really causing headache for me for the last one year. I have tried so many number of solutions available in the Internet including multiple winsock resetting which has helped me for short time. This solution is perfect and has worked straight away. I think this will only work with the intermittent network connection where the network shows connected to the Internet but could not load any website in the browser
