did PLDT give you a username and password to login? if yes...
then you need to set the router to PPPoE and enter your credentials.
if no... then set it to DHCP.
modem should be in bridge mode.
post some screenshots, that would be helpful.
edit:
almost forgot... make sure to put PLDT's DNS server IP addresses in your router too.

Any ideas? Patabang sad unta ko mga master nga maka wifi na ko.
