Either call your internet service provider to refresh the cached junks or by doing a routine check for cleaning the system, or by throwing your router off the damn 10th floor and by purchasing a new router. Land cable would be the best choice, though it's messy.
Im not using it, i use another thing called: Skullproject that has mod except for Dmg Indicators and Toggle sneak search it up
Have you tried putting it in the microwave? Heard the internet binds with the electrons which actually makes your ping decrease significantly
On a serious note: Just build a giant underground tunnel to @Wolfie_strafes room. I believe he lives in the basement of the server. u can then travel to his room whenever u want good ping. On a more serious note: whatever u try,Investing time in cracked servers like GC isnt worth it.GC will shutdown before anni 2.0 is released anyways.
