So I have a cable modem/router combo in one room and in the room I play in I have a wireless network adapter (USB). When I play I notice lag sometimes and eventually the game will send me to the black screen with a 90002 error. If I alt tab fast enough I can see that my internet connection was dropped but quickly reconnects. I have been looking all over but no one seems to have this exact problem. I'm getting frustrated not in the least because I craft a lot and have lost expensive mats due to this. Please help, any suggestions.
