"Release and Renew IP Address
Click on start menu
Programs/Accessories/Command Prompt (not Run!)
type in the command prompt window
ipconfig/all
ipconfig/release
ipconfig/renew"
wait to verify a valid IP address is obtained, it might be necessary to do a "Cold Boot" after this. By that I mean a shut down, not a re-start.
<-------------------- serves no purpose for cleaning a conection...... Your ip is leased by your isp.... your computer doesn't just get to make a new one up..... This does nothing at all for you. . . other than to verify you are connecting to the isp's gateway.
"Also to speed up your web browsing
Command Prompt
type ipconfig /flushdns "
<----------------- your dns address is also leased for a specific amount of time and such if you use this command it will only reset your dns address "IF" your lease has expired and delete the old address..... and that means to the common man that it is a waste of time since your Pc automatically does this every time it is turned off and on. But it could be useful if you were to leave your PC on for a couple of weeks
