I have had enough lag. I've been dc-ing minutes after login, and sometimes within a minute. I find myself having to relog more than 20 times a day. 1) I'm using a Mac Client, 2) I have perfectly fine internet, I believe, which can go up to 6.0 MB/s (just throwing in the highest speed I saw in the last hour). 3) I have my firewall turned off 4) The login and character select process is quite smooth, but after logging in, hell begins. I keep on lagging and disconnecting. I think I've already lost more than 200% worth of exp on my level (52) due to this stupid lag problem. I DC -> Relogin and I get killed by the mobs that I dced from while hunting... We seriously need a 5 second invincibility buff after login or something... ANYHOW. This insanity has to stop... Someone please offer suggestions to stop this ridiculous lag...
To diagnose the issue the first thing we will need to know is the health of your connection to the server. So we would need to see a trace route or more preferably an MTR log. See the thread in feedback called New host feedback.
The packet loss is occurring WAY before your connection even reaches our servers (look at the packet loss on the first hop from your router to the 223.116.166.1 IP). It seems that your ISP is to blame for this packet loss, not us.
