I found this cool thread on how to improve bandwith by using code in terminal. "open the Terminal and type "sudo -s" to access root -type "sysctl -w net.inet.tcp.recvspace=65536" then press enter (increases recieve buffer size) -type "sysctl -w net.inet.tcp.sendspace=65536" then enter (increase send buffer size) - type "sysctl -w net.inet.tcp.delayed_ack=0" then enter (increase your Mac's response time) -type "logout" then enter (if its a login shell) This hack only works for the current boot up (it will be gone next time you start up) so let's fix that: -type "sudo pico /etc/rc" find the last line that should read "exit 0" NOTE: The "exit 0" line is the very last line in the text. You need to hold the down arrow key in order to reach this line. since we want the effect to take place during all boot ups, -type the 3 sysctl commands again right above the "exit 0" line, writing one per line Results will vary, people's bandwidth has doubled because of this. Others have seen no noticeable difference. It sure helped me and I hope it give your Mac a nice speed boost too!"
