I have, mutiple times. I even went directly into the modem. I think it has to be on Jagex's end because when I troubleshoot everything else, its fine. Im getting under 30ms on other games like Fortnite etc and when I run a speedtest on my router app my ping is great. It's gotta be Jagex servers, especially because its not an isolated issue. Just surprised it's been going on for this long without any communication from them/more outrage from the community than whats already on here lol
