My wireless internet speed started to jump up and down.

Hello,

 

Recently I am having my problems with my internet speed. I built a new pc 3 weeks ago and installed wireless adapter (TL-WN851ND) which is 300mbps. These couple of days, my internet connection became very unstable, it's moving up and down at speed. When I play online games, my ping is waving from 30 to 350 which makes it unplayable... This did not happened before, earlier connection was fine. Other devices (smartphone, old pc) have no problem. When I disconnect everyone from internet except my pc, it still  doesnt resolve anything as I'm getting the same problem. What could be the problem?

The wifi card. Make sure your computer has a strong signal, otherwise effects like what you are experiencing will happen.
