Setting up a home or small business network has gotten easier with each version
of Windows, but regardless of whether you have XP, Vista or Windows 7 systems
(or a mixture), you may sometimes encounter problems connecting to the other
computers on the local network or to the Internet. Network problems can be

plugged in or the wi-fi switch on your laptop turned on? More than once I’ve had

instructions to turn off electronics on a plane) and forgotten to turn it back
on. Depending on your device, wireless may be disabled by a hardware switch
and/or through the software (for example, “airplane mode”). Also check your
router or switch to ensure that it’s plugged in and lights are on. Cheap
switches sometimes die suddenly, leaving your network dead in the water.
