Hello, I have recently upgraded to Windows 10 from Windows 8.1 . I searched for a update for my adapter's driver but I couldn't find one, and neither could Windows. My adapter is a 150Mbps Wireless 802.11n PCI Adapter. I also tried to find a driver upgrade for the wifi adapter that is built into my P.C, and I could not find one. So I went on with my day, and found that after about 15-30 mins of being connected to my wifi, my download / upload speed just drops. (It becomes like .2mbps, and it is normaly 20-30 mbps) Sometimes, the router doesn't even recognize that my P.C is connected. What should I do? I searched for a firmware update for my router and couldn't find one.
