Step 1: Connect your Synology Router RT1900ac with your computer using an ethernet cable.

Step 3: Once on the main page, click on "Advanced Settings" > "Wireless" > "Wireless Security". Now from the given form of encryption option choose WPA2 as it is considered to be the most secure among all. Save the Settings.

Step 4: On the Wireless Security page, click or uncheck the box hiding your "Passkey". This is your wireless password or Wifi password. Enter a new password which is strong and can be remembered easily. Use of Uppercase, lowercase, and numerals combined gives you a very strong and nice password combination. Note it down if your memory is not that great. Save the settings, now only those people who have your wireless password can access your Synology Router.
