T3 and T4 errors happening all the time

Up until about last week my internet worked perfectly. Now I'm getting T3 and T4 errors multiple times an hour. Sometimes several back to back. I'm not sure what to do about this. My modem/router is the Nighthawk C7000v2.

 

Please help! I'm a a complete loss of what to do or why this just started happening.
