Computer Lost Internet Connection

my ip address

Most home computers connect to the Internet through a Dynamic Host Configuration Protocol (DHCP) server. This means the IP address is automatically assigned by the server (most likely your router).  IP addresses are automatically assigned (leased) for a time determined by your ISP.  The time varies, depending on the ISP.  When your lease expires you lose your internet connection.

Network Problems because your Wireless Switch is turned off

Many mobile laptops have a wireless switch on the front or side of the computer to enable or disable the wireless radio.  This functionality is usually added to allow laptop usage on an airplane or in other areas with radio sensitive environments.  You can switch off the wireless radio to enable usage of the laptop.  It could be an actual hardware switch or a led light by the keyboard triggered by a combination of keystrokes such as Fn, Ctrl, Alt in combination with function keys ranging from F1 to F12.  If you have a switch, make sure it is turned on in order to receive a wireless connection.

If you don't know how to turn on or off your laptop's wireless radio, consult the laptop manufacturer, or check the link below for a list of various laptop models and their corresponding wireless radio switches.
