Internet started cutting out when I play WoW

Hello,

I hope this is the right subreddit to post this. As of this morning my internet started cutting out after logging into WoW. However, what is reallly strange is that my other devices can access the modem just fine, it is just that my PC disconnects from the internet. I also tried watching netflix on ultra HD, downloading games on steam and watching streams on twitch and none of those caused any issues, so it is not my modem or my isp. For additonal context i built a new PC a week ago and everything seemed fine until this morning. I even played hours upon hours last night and had a stream open in the back, never had an issue. I searched extensively online but could not find a case similiar to mine. Does anybody have any insight regarding my predicament?

Edit: I think I found the culprit. I'm using a usb wi-fi adapter ZYXZEL NWD6605 to be exact. I just tried connecting via ethernet and everything is fine. The problem is I can't have the ethernet cable connected indefinitely as it runs through the middle of my room, that's why I was using a wifi adapter. Also before I built this PC, I was playing WoW on my laptop which was also connecting via wifi and never had an issue similiar to this. Is there a specific setting that I have to tweak with this adapter perhaps?
