I've been having this problem where my Internet shuts off about 1 or 2 minutes after I open my browser. Its not a problem with my Internet connection (I have a 5bar connection) and I can use my I-pad on the internet with no problem. Im wondering what's wrong and how I can fix it.
If you're using wireless, try updating the driver for the wireless adapter first.
You should be able to find information about what adapter you have by opening your start menu, right clicking over "computer" and selecting "Manage". Then, in the window that appears, click on device manager and then open up the drop down arrow next to "Network adapters" You should see your wireless adapter listed there.
And in addition to the above, you might find this tutorial useful in some cases: Internet Troubleshooting Guide - created by Dinesh
