WiFi connection shuts down after graphics-intensive browsing

On my desktop PC, I visit various pages on Tumblr, a photo/video sharing community with pages full of thumbnails and animated GIFs. It's a very graphics-intensive site. Unfortunately, after 10 minutes or so of browsing various Tumblr pages and viewing videos and GIFs there, my Internet connection stops. I then reboot and can only view more "regular" pages that have minimal graphics. When I go back to Tumblr, my Internet connection shuts off again after one or two page visits. These problems persist regardless of which browser I use on my desktop. Importantly, I do NOT experience any of these problems when I use my cheap laptop with the same WiFi connection. So, the problem appears to be my desktop, not my WiFi. When I run Performance Monitor on my desktop, my "average" is between 12 to 12.5. Not sure if that means anything.

I have Windows 10 on a Dell XPS 8300 and a 75/75 router. Intel Core i7-2600 3.40 GHz, 12 gigs of RAM, and 64-bit operating system. 1 TB hard drive. My security software is Malwarebytes and MSE (although I use those on my laptop as well, and my connection is always fine there).

Any help would be most appreciated. Thanks!

I assume that , your issue is not because of high graphics oriented webpages.

while the internet disconnected, have you tried to ping your gateway(router ip) from your windows machine.If you can ping to the router and if you cant go to internet, then u could check something on the Dell router

Usually there are known wifi issue on the 64bit operating systems.

Many thanks for the quick reply. Can you point me to where I can learn how to ping my gateway? I'm a neophyte when it comes to PC fixes. And for what it's worth, I have a Verizon (fios) router - although I have no idea if that matters. Total newbie here, I'm afraid. Thanks again!

While you are not able to browse internet,  go to windows start -- > run --- type "cmd"  --> press enter

you can see command prompt window


Here type "ipconfig" and press enter.. This will display your IPV4 ip address and Gateway details.

on the same window, run this command

C:\>ping (your gateway ip address)

refer the below url for more info

Thank you. I fixed the problem, which was entirely my fault! I noticed that my desktop had a hard-wire internet connection. I disconnected that and now am using the WiFi which is working fine. Points for you regardless. Sorry for creating all this confusion! And thanks again.
