hi guys.. i have the same problem error 81000306.
when i run command prompt and type in: netsh int tcp set global autotuninglevel=disabled it says 'set global command failed on IPv4 The requested operation requires elevation'. what does that mean? my autotuninglevel is now normal. is there any other way to disable it? fyi: im running on windows vista and using a linksys wag2000 router. thx all! :smile:
