I've been having this problem since 2.2 as well. last week I went all week without a single 90k disconnect and then today I get disconnected everytime I enter a dungeon or cs or even talk to an npc. I have reported this numerous times to gm's and se since 2.2 and all I get are mixed answers.. The only common answer that does come up is server lag, keep trying. I've reset my computer as well and it didn't help. I've even changed out pc parts because se at one time said it was my computer. still nothing. I even changed out my internet router and called my internet company, when se stated they were the problem. again no fix.
