MOCA Problem? DVR Box time wrong, No Network, etc


Not sure how to make this Long story short.... I have the Whole House DVR setup.. 1 main box & 3 minis.  Also have cable internet service thru Mediacom.  I'm using Mediacom supplied Technicolor Modem and their MOCA Adapter,, with my own Router.  I recently updated my 12 year old Netgear router to a newer "modern" Asus router.  Everything had been functional for years up until the router swap.  The swap was a straightforward deal.... same ethernet cables, same end-to-end location labels, etc, etc.. nothing else was changed, except for a router box.

Current situation is this:  my LAN connection to 2 pc's works fine, wifi works fine... zero issues with my broadband internet access.  

My cable TV has issues though.   Main DVR box works as normal, with the exception that it displays the wrong time on the box/on-screen guide (off by 50 minutes - delayed to actual time).  It also shows "Tivo Service Connection - Failed" in the menu settings.  I CAN access my recordings, watch them, record more...  All 3 Minis have similar problems... none of the 3 show any of the "info" associated to shows in the onscreen Guide.  All 3 have various errors on their onscreen clock times (1 off by 1hr 10min,, and 2 off by 1hr. 25min)..  They ARE all functional to watch TV, and view previously recorded DVR content.

My MOCA adapter power LED is in a constant state of blinking (manual indicates this is a reboot mode?)..

I'm assuming the Network failure I'm seeing in the DVR settings is MOCA related, causing no internet access to my TIVO system... and also the clock issues, etc... ??  

Phone tech support got me nowhere last evening... I believe they entered a "ticket" for someone else to look into it.

Is there a specific order of rebooting, powering up all the boxes (DVR, modem, router, MOCA dongle, etc..) that I could try?  Maybe the router replacement while a Mini or Dongle was powered up has created an issue where the system is totally lost?


One other question, just to make sure a connection didn't get switched around:  

Router "WAN"ethernet cable goes to 1 of the Modem's Ethernet ports (per Router documentation)..  and, Ethernet port (labeled "Internet") on MOCA Adapter goes to a LAN port on my Router...  Correct??

Thanks for that info, Wrinklez. Since you use a personal router that should be the correct set up for the adapter; Modem port 1 to Internet/WAN port on router and MoCA would be connected to the router(port 1-4, etc). The blinking power with no network light indicates the MoCA struggling to establish a network. If you have already re-seated the ethernet cables I would try alternate ethernet cables to see if there is any immediate improvement. 

Ended up being a bad MoCA dongle /adapter... its a Mediacom piece installed 15(?) years ago... it finally had enough,,  wouldn't power up properly.  Service Tech swapped it out, instantly all problems were fixed.
