I join a roblox game, and within a variable amount of time (anywhere from 2-10 mins usually) I disconnect with the error: "Please check your internet connection and try again. (Error Code: 277).
In roblox studio, I launch up studio and within 2-10 minutes, the symbol in the top right turns from green to red, and then after a bit it disconnects. All the work that I do while its red disappears.
This happens every time on every game I go on, and if I recall correctly, I first started noticing this last friday.
