!!!! ---- I think we might have a solution ---- !!!!
Here is what fixed it, drop to a command prompt and run:
netsh interface tcp set global autotuninglevel=disabled
If the command returns this response, "Set global command failed on
IPv4 The requested operation requires elevation", then you need to do
this:
Click start (windows symbol), Accessories, right click on "Command
Prompt", then choose "Run as Administrator", then try the netsh
command (above) again.
This worked great!
Special thanks to my friend Mark G. for digging this up!
