Click Start>all programs> accessories> command prompt.
the command prompt will open (black screen, etc.)
type the following:
ipconfig/ release
then press enter.
it should show your IP address as 0.0.0.0 along with your Subnets and some other stuff. once it does, type the following:
ipconfig/ renew
then press enter.
after a few seconds (up to a minute maybe) it should show your ip address as 192.168.etc.etc. now your internet should be working. go into IE and press F5 to see if your web page will refresh.
if this doesn't work, you may need to power cycle your router and/or modem.
to do that (if the command prompt steps didn't work) just pop the power cable out of your router or modem for about a minute and then plug it back in. wait about another minute and check the connection on your computer it should be working.
if you have both a router and a modem, power cycle the router first and check the connection. if that doesn't work, then power cycle the modem and check the connection.
Good luck!
