You just have to perform a hard reset on the modem to erase any previous data stored. Locate the small pinhole for the reset button on the bottom of the modem box if it is not at the back. Then you need to access modem gateway to put all configuration information on modem software by typing in in your IE browser's GO TO website box (where you type website address/URL)

NOTE: Make sure that you know your username and password for your current internet connection configuration before RESETTING modem. If you don't have this settings, call your internet provider. =)

do you also have AT&T? att2wire 2701hg-b gateway is configured to work with AT&T only that's why if you have a different ISP, it will not work for you. Most ISPs provide modems that are configured solely for their service.

I have problem using my ip add given by pldt

no the zyxel modem you stated is not a router. you would need to plug in your router first then plug in your modem to the router then turn your router on first then you modem and then your pc your d-link roter should automatically configure itself. you just need to repeatthis everytime you connect another pc to the router.. :-)

Can't Open Internet Explorer

You have to contact your service provider. That's a thing which is done by them to secure there internet service. They will give you the username and password. I evn tried that and they asked me to type the modem name and 'admin' as a password. For example, my modem is STstarcom. so the username wax starcom and password: admin.

Thank you.
