High error rate and massive drop in speed first thing in the morning

Lately I have been having issues with the internet speed dropping really low first thing in the morning.

 

I am on the 75mbps tier and I normally see 90-100 down and 5-7 up...

 

However first thing in the morning I was getting massive drop outs on my VOIP phone and huge delays on my work computer connected to a VPN...  when i tested i was seeing 3-4 up and 5-7 down...

 

each time a reboot it corrected this restoring normal function, but then first thing in the morning the next day it was back to 3-4 down and 5-7 up...  again a reboot corrected this

 

I figured that i had been running this router and modem for 3+ years, maybe it was time to upgrade...???  

 

I also decided to take a look at modem internal config page... (Zoom 5345)  Within minutes of a reset i was seeing several uncorrectable errors

 

Downstream was around 5.0 dBmV, SNR was about 35-40db

 

upstream power was about 45.5-48dBmV

 

-------------------------

 

Here is where it all gets interesting... over th weekend I had disconnected the cable feed from the house and removed some unused splitters, one went to a peice of broken cable, the other had been capped off with a terminator...  other than that the only thing inline was a ground block...

 

in retrospect I should have been looking at this... 

 

especially since i have lived at the house since late 2008 and the cable line was there  when I moved in...  botht he drop and the in house line...

 

---------------------------- 

 

BUT I decided to purchase a new modem... Motorola MB7420...  less than 18 hours after powering up this is what i see
