X1 low signal strength

I have seen the low signal icon on my TV for months.  I have even switched X1 boxes, but am still seeing the low signal icon with the new X1 STB.  I have restarted the box multiple times, checked all of the cables for damage and made sure the connections are secure.  Do I need to have Comcast check the connection at the street?

You may possibly need a tech but I wouldn’t worry about it until you see issues. The x1 box has an interior modem and one or more of the channels that modem is reading may be out of spec. Things you can try yourself, make sure all the cables are tight and in good repair and remove any unnecessary splitters to add to signal strength. Swapping boxes is wasting your time

Upstream, downstream, and SNR. The numbers are for the interior modem the cable box has. It has to be in the same specs as your modem.
