Unreliable connection since new modem...
I had a very old modem (it was free from Cox years ago) and upgraded to a Arris SB6183 in April. Had some connectivity issues and bought a D-Link DIR-890 Wireless router in July thinking that would help too. Ever since then I have had nothing but troubles. My old modem might have been slower, but it stayed connected. What tests can I do to determine the issue? This is the status page of my modem.

None of the downstream signals look bad, SNR is very high, power is very good, right close to 0. I don't see the upstream signals, that is usually a cause of frequent disconnects.
Also, can you look or copy/paste the log information? That usually will tell us why it is disconnecting, or what is happening right before you power cycle it. At this point, I can't determine which is more likely, modem or router triggering of your issue. Heck I just had an issue with wireless drivers for a realtek wifi adapter that was disconnecting 3 to 4 times an hour, but the rest of the devices weren't suffering the same issue. (Stupid Windows 10 updates)

Everything is disconnecting, whether it's wired or wireless. I do have a switch I could run into before the router, if that might help to eliminate the modem.
Here is the event log from the modem.
Here is the upstream info

Your TX values are too high - usually you want 50 or lower, up to 52 with certain modems works...
SYNC/T3 issues will pop up when TX is too high, it basically means that your modem is 'yelling' and not being heard clearly.
Check connectors/reseat connectors on the coax - if your modem is on a splitter try to bypass it. If you've got an attenuator or filter on the line, try removing that as well. All else fails, this is usually something that an on-site technician can check. But check your wiring/connectors first, if it's something there you can usually fix it faster.
