Alright so I made an account here to get some help on my problem. Whenever I join a server, I spawn under or outside the designated area and lag very badly, until I lag out after about 10 seconds. I have a brand new computer, with windows 7 64bit that runs minecraft at an average of 260 fps. This happens on all servers. I have tried just x86 java, x86 and 64, and just 64 java. I have tried the same combination with java 6u43, all to no avail. I have tested my network speed and it seems to be fast enough to run minecraft. I do not have hamachi. I have completely turned off my firewall. I have reinstalled minecraft multiple times, and now I have no clue what else to try. I can list my computer specs if they are necessary. I have a TP Link 300 Mbps pci card, and my router supports 150 Mbps. Thanks for the help.
Edit: the error message is like Internalexception.socket etc.
