Hello to all. I've been having trouble with Windows 7 Internet connection after freshly installed it not long ago. My Internet connection kept giving me a yellow sign error (disconnected from My computer to the Router) when I download or transfer large files. I had to go to Change Adapter Setting and Disable, then Enable the adapter to get the connection back on again. So, after searching and reading numbers of posts related to this issue, unfortunately not many people found the fix for this problem. Today, I just finally fixed this, and would like to share this with people who had the same problem with me. It seems the problem is mostly for people who is running Windows 7 with nVidia chipset. So here is the fix. 1) Go to "Network Connection" and click on the Network NIC card you are using, select "Properties" 2) Go to "Configure", "Driver", and click on "Update Driver" 3) Click on "Browse my computer for driver software", then click on "Let me pick from a list of device drivers on my computer" 4) Select "NVIDIA nForce Networking Controller (Microsoft)" and click "Next". Follow the instruction and install the driver for the NIC. 5) Go to "My Computer" and "Uninstall or Change a Program", look for "NVIDIA Network Manager" or something like that and Uninstall this program from your Computer. Follow the instruction and Restart your computer. 6) You have solved this Windows 7 Disconnect problem. Sorry for my poor English. Hope this will help people who are also looking for this fix.
