My computer completely loses connection to the router when i try to connect to my own server (which is correctly connectable by the way) Even when i try to connect to it trough a laptop (server ran on desktop) the laptop retains internet but the desktop disconnects from the router for some reason.
It doesn't matter what you do, the servers will lag, there is no point in even trying to connect, the game is unplayable in its current state.
And now Notch is away for a few weeks, so we can't expect any fixes.
Since when is Tuesday a few weeks? More like a few days.
And I'm thinking some of the lag, at the moment, also depends on the server computer itself. After all, it's processing a lot more information for a lot more people than normal single player. It's potentially generating new land for quite a few people at the same time, and that can slow down a not-so-good computer pretty fast, hence, lag.
