as soon as I see this message "Unicast Ranging Received Abort Response" , I see that reset was initiated from ISP side (Mediacom). also, if you have lot of uncorretables, that is another sign of RF issue from ISP.
We had a another community user from the same ISP with similar issue. he resolved the issue by removing unnecessary splitter(s) in his home.
DoS attack info is ok as it is an internal packet. You can ignore it.
Time stamp is apparently central time (1 hour ahead of local) despite being physcially located in AZ.

which device were you using before?
This is the 1st cable modem with Mediacom. I was using VDSL from CenturyLink but their best offering was only 25Mbps down/0.8kbps up in my area. Need the higher cable modem speed (150Mbps down/25Mbps up) from Mediacom. IF it can become reliable.
