Lose Connection when connecting to SL

When i get into the game, it shows i have 0 bandwith but i'm absolutly fine in any other game, i have far better computer then what requirements ask for so i'm good on computer part of it, now i'm just wondering why do i lose my connection when trying to connect/connected to SL, i figured it was my Port so i opened up the port manually changing the one provided to me through you guys. I tried pretty much everything i could think of to solve this problem, still have the problem. So if anyone could tip me on the current situation i have that would be great because i dont even get to play a second of SL anymore now because i get disconnected instantly.
