GPS satellites help mobile devices and computers keep accurate time.

Question. How do my computers and phones know when and how to adjust their clocks for different time zones or times of day?

d. Their devices use amazing technology to keep track of time.

Cell phones and computers use data connections to communicate with Internet time servers using a protocol called NTP to retrieve and obtain the current date and time.

Internet time servers track time from various sources, usually GPS satellites, and record Coordinated Universal Time, commonly known as UTC, and transmit this information to Internet-connected devices.

Your devices use location data to convert UTC to your specific time zone in order to give you the correct time for your location.

Location data comes from your devices, depending on where they are connected to the Internet. Your home IP address, for example, gives you location information for all the cell towers your phone uses when you use your data plan.

Because your time zone and physical location are adjusted for daylight saving time, your phone and computer can be perfectly adjusted to meet your needs.

Q. I recently changed the password on my Wi-Fi router and now my computer won't connect. It fails and won't let me enter a new password. How can I fix this?

d. Your computer saves your Wi-Fi connection settings to make it easier to reconnect when it's time to connect to your home network. When you change the router password, your computer will continue to connect to the password you set in the configuration.

To fix this problem, you need to tell your computer to forget the network to save the new connection settings.

On a Windows computer, click the Start button, click the Settings icon, and then open Network and Internet.

Click Wi-Fi and select Manage Known Networks and find and select your Wi-Fi router and click Forget.

Now search for Wi-Fi in your home and you will be prompted for a new password when you connect.

If you're using a Mac, it's basically the same. Open System Preferences and click Network. Select Wi-Fi in the left column, then click Advanced.

Here you'll see a list of Wi-Fi networks your Mac is monitoring. Select the one you want to remove and click Remove. This is the key that looks like a minus sign.

Click OK and you should reconnect and enter the new router password.
