How to Reset a ZyXEL Modemby Mandy SlakeUpdated September 28, 2017
The ZyXEL Prestige series of DSL modems is equipped with a reset button on the back panel that will restore the modem to its factory defaults. If your ZyXEL modem is acting up, try resetting it before you call your Internet service provider's technical support. It can save you the time waiting on hold, and possibly prevent the hassle of an on-site service call.
Examine the back panel on your ZyXEL modem. You will find an "ON/OFF" button and a small round hole labeled "RESET."
Turn off the modem.
Straighten one end of the paper clip and push the end of the paper clip into the hole.
Turn on the modem. Continue holding the "RESET" for approximately one minute.
