Connection Issues with Wifi USB Adapter Model A7000

So ive had this Nighthawk Ac1900 usb wifi adapter and its seems to be working besides one issue. About every hour or 2 the adapter will randomly stop its connection and i wont be able to access the internet and will interrupt an online match in a video game i play. Whats strange is that the wifi signal will still show 3 bars on my desktop screen but will not be able to connect to the internet. When i check the adapter it self the blue LED will be turned off. This mainly occurs in the middle of a game and not often when just browsing the web or listening to music. Ive tried many solutions but none seem to completely fix the issue. Any help is appreciated thanks.
