For those of us less tech savvy, how does this help? How do I even find out how to reset network controller? Is this a one-time fix, or something I have to do regularly?
I use Windows 10, Brazilian Portuguese, hope I can help you somehow: Right click on the network icon next to the clock> open network and internet settings> Network and Sharing Center> Change Adapter settings> 2 clicks in your network controller> properties. Will open a new window, click settings/configure, will open another window, select the advanced tab, in the list of items to configure, find speed and duplex, select 100Mbps Full / Half Duplex (test both).
For me it was a one-time fix that completely resolved. I don't need to change anything else, even restarting the computer.
I have a 200 mbps but with the cable goes to 10 mbps while with usb adapter goes normal.
After making the change mentioned in the quote the network card is no longer working...
Please help me!
