Is the reliability of my connection up to Shaw standards?

Cisco DPS3825 router that I have had for two or three years. I am happy with the connection speed when I am connected.

 

Last summer I had the perception that my Internet connection was being dropped frequently. I saw a hint on the forums that those routers may be affected by high temperatures, and that maybe they could be exchanged. A phone call to Shaw suggested that I explore the possibility of a bad connection.

 

Reliability improved once the weather cooled off, but beginning this March, the intermittent connection problem returned. I wrote a little script to gather some statistics.

 

Since 22 April, my connection has failed 165 times for at least one minute. These were the failures for 17 May:

 

2016-06-17 01:31:01 DOWN

2016-06-17 03:18:01 UP

2016-06-17 12:06:01 DOWN

2016-06-17 12:13:01 UP

2016-06-17 12:58:01 DOWN

2016-06-17 14:04:01 UP

2016-06-17 15:26:01 DOWN

 

The failures are not distributed uniformly throughout the day:

 

00  8

01  13

02  10

03  15

04  15

05  4

06  1

07  0

08  3

09  15

10  15

16  0

17  2

18  0

19  0

20  1

21  2

22  4

23  3

 

and (although the sample size is small) they do not seem to be distributed uniformly through the month:

 

01  17

02  4

03  13

04  1

05  0

07  9

25  10

26  1

27  1

28  9

According to the DPC 3825 manual, the pattern of lights during the connection failures indicates that the modem is "Ranging".

 

Any suggestions?  Thanks.
