|You friend is right, you dont need a CD, just the right IP address to get into the configuration. 192.168.1.1 might not neceserily be the rigth one.|
To find the right address set the router to factory defaults, you never know what the pervious owner might have done. That should enable DHCP and put IP address and passwords back to there defaults..
Go to a command prompy and type ipconfig /release then ipconfig /renew.
When its done do ipconfig /all. Look at the default gateway address. That is the IP address you need to get into the router. The default user name and paswword should be blank.
