CM1000 MDD message timeout

[franklioxygen]

My ISP is xfinity, they said nothing wrong from their end. 

They send some signal not receiving proper response.

I found this in the log:

Can someone let me know it's device or wire issue?

you can check for bad ends/loose connections. 

If there isn't any, then they would need to check the line

[plemans]

Any splitters, amplifiers, or signal attenuators in your cable line? If so remove them. 

Preferably, move the modem to right where the coax enters the home. This prevents wiring/connections in the home from being the issues. 

If that isn't an option, check the coax cable for kinks, damage, old/bad/cheap/corroded connections and remove them if you have them.

Thanks for replying,

It is the coax enters the home. No splitter or anything else.

I might need ask technician to come.
