Step 1: Connect your Synology router to the computer using an ethernet cable. One end of the cable goes inside the internet port of your router while the other end goes into the ethernet port of your computer.
Wait for few minutes to let the connection between the two system establish.
Step 2: Open your web browser and type in your IP address in the URL field and hit Enter. In case you do not know your IP address, simply Google,"My IP address" or "Synology router default IP address" and you can copy that in the URL field. This will take you to the login portal of your Synology router web portal.
Step 3: Once on the login portal, fill in your login credentials in the given box provided by your Internet Service Provider. In case your service provider did not give you any username or password then fill in the default ones. The default username is "admin" and leave the password field blank and hit enter.
Step 4: Once on the main settings page, go to "Advanced Settings" > "Security". Here, you will need to make some changes to make secure your Synology router.
First, change the encryption type to "WPA2" from the top as it is considered to be a government-grade encryption method and very difficult to crack.
Step 5: Below the encryption box, you will notice a box for "Passkey", this is your wifi password, change it to a secure password by using a combination of uppercase letters, lowercase letters, and numerals.
Note down this password on a piece of paper or take a photo in case you forget. Save the settings.
Step 6: For making the security even better you can make use of "MAC Address Filter", Mac addresses are the permanent address of a hardware and every device has a unique one.
So in case you want only a certain number of known devices to get access to your Synology router then, add the MAC address of these devices here and save the settings. Now only those devices whose MAC address has been added can use your router.
