Intermittent Internet - Default gateway is not available

I am getting disconnected from the internet on a fairly regular basis. If I run troubleshooting, the error I receive is "the default gateway is not available." This is a new problem with Win8 as Win7 ran flawlessly and nothing has changed other than upgrading to Win8. I have updated all my drivers but am having no luck. It should be noted that if I attempt to play a game such as League of Legends that I will randomly experience disconnects and have to reset the Wifi adapter every couple of minutes. Let me know what you guys think, I am really unsure how to fix this.

 

I am using the Realtek drivers.

 

Yes, I am using the second one listed for my device:
Windows driver auto installation program (support Win8) 2007.3.0821.2012 2012/10/31

 

Still experiencing this issue. This is the only computer in my house with the problem, and the only one running Win8.

 

I think I have experienced something similar. What I did was to delete all the connections. Re-connected them. Then everything worked fine. I suspect it's a bit of confusion created by having different connections.

 

I only have one connection and have never had any other connection on this computer. However I did try deleting and re-connecting, I will let you know what happens.

 

Still having this issue. It seems every time I sit down at the computer after being away for a while the internet will be down. During games or watching videos, I will often get spurts of lag that require disabling and enabling the wireless adapter to fix. This issue never happened during Win7, only once I upgraded to Win8.

 

I am also having the same problem with my dell laptop with windows 8 and looking for solution. It was disconnecting in regular intervals. Even dell people didn't solve the problem.

 

I downgraded to Windows 7 and haven't had a single disconnect since. There's definitely still some issues with Windows 8.

 

This seems to have worked for me. It makes sense too. Mine would quit when on battery and run fine when plugged in.

Device Manager
Open the network adapter (in my case Intel Centrino Wireless-N 2230
Click Power Management
Clear the box that says "Allow the computer to turn off this device to save power"

Worked for me. Best of luck,

 

It already had the appropriate driver installed and selected. It was not set to turn off the device to save power. Still not a single issue with Win 7 - just going to stick with 7 until 8 gets more of the bugs ironed out.

 

I had this problem on my other Windows 8 Laptop. Worked around it by reinstalling the network adapter.

 

Thanks Nibiru2012 and Bakerman! This Windows 8 issue had been driving me nuts, and your solution worked perfectly!!!

 

Try left clicking the wireless icon, then right click the connected device.
select "View connection problems"
You will get yet another window.
You could check that you have the first and third option checked:
"Connect automatically....
Connect, even if the network...."

 

I am facing the same problem. But when I go to the device manager and select the wifi driver, I do not see any power management option . please help...screenshots attached
