The Killer AX1675x on my MSI GS66 stealth laptop has been acting weird lately. It has much lower speedtest wifi speeds than my chromebook (500mbps download, 400mbps upload) and my Iphone (350mbps download, 150mbps upload), as it usually gets about 100mbps download and 200mbps upload, but this is not the main issue. The main issue is that sometimes the speed goes down to around 1-2mbps upload and download, and that is a huge issue. It doesn't seem to struggle that much when doing more intensive like cloud gaming, but whenever I do something less intensive such as watching youtube, it will load a small chunk of the video and it will completely stop doing anything, with the speed going to 0 in task manager while the video is still buffering. There is also a crazy amount of lag in games like fortnite, as whenever I try to do anything in game, the wifi just freezes and lags me back, not letting me do anything. Is there any fix for this in software, or should I just replace the wifi card?
