I have G402 and G304 both connected to the same computer (G304 was supposed to be brought around. But since pandemic, I use my computer more often). I use D-Link DWA 548 for the wifi adapter (PCIe). So lately, I use G304 primarily 'cause, it's wireless. I don't have to deal with cables. But my wifi decides to lag everytime I play games. Believe me, I have to rage in every games 'cause of sudden ping spike. This morning I change my mouse to G402 mid game and turn of the G304. I don't know why but the ping spikes were gone. FYI, I was the only one using the wifi that morning. Is it suppose to happen? Has anyone ever experienced it? Any explanation would be great. Thanks in advance!
