Windows 10 x64 Asrock Extreme 4 Gen 3 2600K AMD 7970 Netgear Nighthawk AC1900 Wireess router/modem Linksys WUSB6300 USB adapter Its freaking fast and I love it. Only problem is that using my wifes compuiter with the AC1900 causes drop outs. I can use my old usb 2 linksys adapter and it doesnt happen. Did I get a bum adapter? It just seems to drop after about 2 hours of use. Its the only device on our home wifi. Not sure what to try.
