Hey bud, I'm running RS3 and OSRS on a Samsung Galaxy Note 20 Ultra 5G on the same type of wifi and most of the time it just says no "internet connection" as soon as I shut off wifi and run off 4g/5g the game runs ABSOLUTELY flawlessly with every setting completely maxed out to the best it can be and i have zero issues. Problems only come to fruition when I'm in wifi -_-
