Cox Contour (Arris ax013nm) diagnostics screen / signal strength?

is there a diagnostics screen / signal strength on the Cox Contour (Arris ax013nm)?   for the past two weeks I get a RDK-03030 error message and must reboot the DVR.  it takes much longer then it use to boot back up.  4 to 6 minutes when it use to take 2 minutes. 

Had a tech out yesterday and said I had horrible signal strength he ran a new line from PED to house, that did not fix issue if it was even an issue.    I would like to test signal strength as it could be PED to COX servers.    I am guessing I have to swap DVR but wanted to test signal strength before trenching new line and losing all my recorded shows.
