Can you connect to the internet? I suggest you to raise this to our Twitter Specialists at http://www.twitter.com/talk2GLOBE or any of our support channels listed at http://www.globe.com.ph/contactus so they can help you isolate the issue, and if there's a need to log a network case for investigation.
There may be misconfiguration in the router when you reset it. Preferably do not reset it next time and call Globe to replace your modem again for free.
Im also having that problem atm, i googled everything out but cant find the solution, i guess i just need to wait tomorrow to fix my prob by a globe technician.
After you reset you modem, try doing this;
1. Go to 192.168.254.254 the click login
2. Type "user" as username and password to log-in to your modem GUI
3. Select "Quickstart"
4. Type in the username and password provided by Globe for your account activation.
5. Click "Apply".
Ex. username: email@example.com, password is dec00000000736.
