For one, you have to Querry LAN to join your own dedicated server.
Two. The distance form your router doesn't really help the connection. I mean yeah, 100 feet will diminish it. But your house isn't a hundred feet long. It's either a good connection, or not. And from the amount of complaining you're doing. It's a crappy connection.
Three. Stop complaining. There isn't a single thing me or anybody else on/in these forums can do about your crappy internet. You just have to deal with it.
Just because you have the connection DOES NOT mean it is a good connection.
