You mention you installed the OS but did not mention any post-OS work. Just like all Windows before we get to find and install drivers and apps required for our hardware. I don't see any mention of this.
Don't take it too hard, I'm running into new folk all the time that do this and then have troubles. Easy fix? Use the maker's restore media.
I am Daniel Esterly and I am Ph.D. student. I have recently installed Windows 10 on my system but after intstallation I have noticed that when I connect my laptop to internet through Wifi, after sometime it wifi shows a exclamation sign with yellow color and internet stops working. What is the problem?? Please guide??
