So I've recently built my first gaming pc and managed to make an actual functioning pc first try. Ever since I got the PC my ethernet adapter started to not work so i just got a Network card at Curry's PC world (which was a TL-WA801ND) and it's not really working that well.

For some reason when ever I play games like Counter-strike, gmod, or any other online game with my friends my ping would go way higher than it should even go around 150 ish on average and sometimes the ping would just increase and increase to the point were I rubber-band everywhere and end up having to leave games because it's practically unplayable.

There's also a problem with my download speed which when I had the ethernet adapter was around 20-50 Mbps but now it's usually 2 - 6 Mbps which really is just unacceptable.

If anyone knows what the problem is and a fix to said problem, please tell me!
