NPC Name:

Monster Name:
Any and none.

In-Game Time:
All the time. Between 1 min of logging in, usually happens every 6-10min.

Steps:
I can’t do anything in-game without 90king or spiking. Not solo play, not group play. Not crafting, not gathering, not leveling my chocobo. Not anything. It’s becoming a problem for my static as we’re trying to learn and advance in the Final Coil of Bahamut. I either lagspike horrendously making me unable to dodge or I just flat out 90k.

In an attempt to rectify the problem I have gotten a new modem, BOUGHT Pingzapper, ran pingtests, reset router and modem, reinsalled the entire game.
