Now, connect your new modem to the electrical outlet.
  4. Your modem enters boot mode, so wait for it to boot up. The modem has a status light at the front, which will start to blink when the modem boots up. Wait until the status light turns solid blue. This can take between two to five minutes for a standard process. However, the process may take up to 20 minutes if the modem needs a firmware update.
