Try to do system restore first > click on start > all programs > accessories > system tools > system restore.
select CHOOSE A DIFFERENT RESTORE POINT and then click next. CLICK the BOX that says SHOW RESTORE POINTS OLDER THAN 5 DAYS so that you will be able to see restore points created earlier than 5 days.
Select a date in the list (suppose to be a date prior to the date when the problem started happening)
and then next and finish, proceed until the computer reboots. If that didnt work go to the next step.
click START>RUN>and then type CMD and you're gonna see command prompt window (black screen)
type ipconfig /all
can you please post the following here:
UNDER WIRELESS INTERNET CONNECTION
dhcp enabled : yes or no?
after you posted these informations we can start from here. It could be an application problem. Your computer is not getting an ip address from the DHCP SERVER (ROUTER) and your TCP/IP might need to be reinstalled.
