Check your connections, it should be like this: PLDT modem -> router -> computers. If you connect a computer to the PLDT modem, it won't be seen by other computers in your network. Make sure that all of your computers are connected to the router, and not to the modem. Your modem should also be connected to the router's WAN port and not on the LAN port.
