Occasionally it seems appropriate to reboot the Xplornet modem. Whether it’s because it’s actually required or the Internet connection is so poor that you’re flailing for something to do to try and fix it, it’s marginally more convenient to restart remotely than going and unplugging it.
Xplornet tends to install their equipment with a default configuration, including default credentials. Note that if you muck with the settings, you could easily cause yourself to lose your Internet connection and need a service call to repair it.
