Internet: Sync timing and critical 3 timeouts

Hi,

My internet cuts out for two minutes at a time multiple times a day.  I reached out to Motorola - I have a Motorola modem -  and sent them my logs and this was their reply:

Jillian here from Motorola Technical Support. I am happy to help. Thank you for sending over your Event log and connection page. 
 
I see you have quite a few Sync Timing Failures and Critical T3 Timeouts. I recommend reaching out to your ISP and having them send a tech out to get this fixed for you. Here is a bit more information on T3 timeouts for your convenience.
 
The cable modem has sent 16 ranging requests without receiving a ranging response reply from the provider. The cable modem is, therefore, resetting itself and restarting the registration process to the service provider.
 
This is normally caused by noise on the upstream side and can make it so the modem's power level is not sufficient enough to transmit messages. The inability to transmit messages within the timeout period will trigger the reset and restart the registration process. A T4 timeout is a more extreme version of a T3 error.
 
Generally, this indicates an occasional, temporary loss of service, but if the problem persists and is increases in frequency, it likely points to a larger issue with the condition of the coaxial network outside of the home, the cabling outside of the home that will need to be addressed by the service provider.
