A 5ms round trip isn't causing noticeable latency in games.
You are just bad. Stop blaming your router. You sound as dumb as idiots plugging in controllers because they think they are a step away from being a pro gamer.
Well it'd be fine if it actually was 5ms round trip, however even with Wifi 6 you're looking at ~90ms round trip, which actually is a noticable difference.
You can hate all you want, but I tested my xbox controller connected to the PC via cable, bluetooth and the xbox dongle. The dongle was very much on par with the cable, probably because they use a custom 5GHz protocol, but bluetooth had noticeable latency. It's not horrible, but clearly worse than the othet 2 options.
