FAQ

Does blinking red mean my internet is down?

For the WPS light, blinking red means the WPS connection attempt failed. It does not always mean the whole internet connection is down.

Should I reset the modem?

Restart first. A full factory reset should only be used if official support tells you to or if you are ready to set up the modem again.

Can I ignore the red WPS light?

If you are not trying to connect a device through WPS, you can usually connect manually with the Wi-Fi password instead.
