Since SmartBro is now PLDT HomeBro Ultera, most legacy canopy accounts are being upgraded one by one (whether you like it or not). If your SmartBro account is now converted to the new PLDT version and you'd like to make changes that are at least allowed like changing the Wi-Fi name and password, here's how to do it.
Begin by bringing up the command prompt. How this is done varies depending on your computer's operating system. In general, typing CMD on the search bar will pull up the command prompt window.
Type "ipconfig" after the computer user name (in the image above it's after Marcyscreed) and hit enter.
From the results, look for default gateway. This is the URL you will enter on a browser's address bar in order to open the Internet Service Provider's (PLDT) interface. Make sure your device is connected to the right ISP (in case you have multiple Internet source) when doing this in order to accurately get the default gateway address.
The Wi-Fi password on the other hand can be edited by going to Security, still under the Wireless tab.
