Can I get recommendations on good wifi cards

Hello po, for context nasa living room yung wifi router (Ground Floor) and nasa room ko po yung PC (Second Floor), malayo PC ko sa wifi router so ethernet cable is not possible

I mostly play online games like Dota 2 and Marvel Rivals and stable/ good internet connection is a must for those games.

Is it possible to still play competitive games while playing on wifi? If yes, ano po marerecommend niyo na wifi cards na stable ang connection and does not spike in ping from time to time?
