Unfortunately I would need to buy a cable for that, and its still weird, it started doing this like 1 week ago, is there anything else I can do?Test connected via ethernet. This is a extremely common issue when you connect via wifi which is why they say never play online games on wifi. Testing on ethernet will show if it is something else which you hope since you might fix that. There is really no fix to wifi problems, many times it is interference from outside your house.
It would make sense if other players have the same problem, so im inclined to think that it isnt just code.UnLegitCombos, sometimes it's all about game code itself, and has nothing to do with your hardware.
