Here's a possible solution if you find that your PLDT myDSL internet connection keeps loosing synchronism with the PLDT server.
The problem, when it occurs, usually requires a reboot of your modem and router equipment to reestablish an internet connection. The reboot can be done by switching the power supply off and back on to the equipment. The operation usually takes a minute or two to reestablish a link to the server.
The current standard modem for PLDT MyDSL is Xyzel P-### series. You will notice that it has three LED lights as its indicator.
1. DSL LED
2. Ethernet LED
3. Power LED
All lights should glow and blink when the equipment is working properly. A glowing DSL LED indicates a link to the server, a glowing Ethernet LED a link to the computer, and a glowing Power LED a link to a power voltage supply source.
For a while I was puzzled why at certain times of the day my modem and router equipment would need a reboot to reestablish a data link between my computer and the PLDT server. The need to constantly reboot equipment is a real pain especially if I you are using a wireless connection from your router to somewhere else in the house.
Eventually I realized that my PLDT Xycel modem was very sensitive to the voltage fluctuation to the residence. Especially in the evening, when the voltage rose well above 220 volts, my computer would lose its link to the server. Sometimes during the day, when the voltage dropped below 220 volts, the equipment would also need a reboot.
The solution to the problem came when I installed an Automatic Voltage Regulator (AVR) to supply my modem and router equipment with a constant regulated 220 volt supply. Now I rarely have to reboot my modem and router equipment anymore.
An alternative solution might be to replace your old single voltage modem with a new multi-voltage modem which is designed to handle voltage fluctuations better than the older type.
Hope this helps.
