Re: Frequent 30 second outages

I'm getting drops daily of our internet service.  I had the modem replaced by Xfinity.  My signal strength and level appear fine.  I logged into the modem for the last two drops and both times at the time I lost internet, I saw this in the Firewall log:
FW.IPv6 INPUT drop, 8138 Attempts

How do I stop getting this to drop daily?  Sometimes it will reconnect automatically.  Other times, I have to cycle power on the modem.
