  • Ensure the installation of a single-port filter on all jacks with the phone devices and listen to the dial tone and make sure that the filter works.
  • Also, ensure that the jack where you have installed the gateway or modem has a dual-port filter. And, the gateway or modem is plugged into the HPNA/DSL side of the filter.

Check the Gateway Location

This is to avoid the weak Wi-Fi signal:

  • Always place the gateway at the center place in your home.
  • Keep other appliances away from the gateway that sends wireless signals like cordless phones or microwaves.
  • Do not place the gateway directly against a cabinet or a wall.

Check the Gateway Lights

  • At first, confirm the Broadband, Service and Power lights on your gateway are solid green. In case, they are not green, your gateway might have a problem or you are unable to get a signal.
  • Unplug the power cord to power cycle your gateway or modem. After this, wait for 2 minutes and plug it back in.
