Here are the few things you should do to protect your PLDT Home DSL Internet Connection. You can also apply this on other internet connection.
1. Change Wi-Fi Default Password (Use Strong Encryption Type). Dont use WEP because it has been proven insecure and can be cracked in a few minutes using free utilities/applications that can be downloaded from the Internet.
2. Change Router User Account Password. Aside from changing the Wi-Fi password, You should also change the user account password of your router, because someone who have access to your internet connection can enter your router settings by using router's default username and password. By changing the router's default password, you prevent allowed users to access your internet by entering the router settings.
3. Disable Wi-Fi Broadcast SSID. This feature simply means to hide your WiFi SSID/Name. When you turn off SSID broadcast, others won’t be able to pick up the broadcast of your wireless network and this will cut off the chance for them to hack your Wi-Fi network.
4. Restrict user access. You can restrict user access so that only specific computers/devices can access the network.
