So, I came home today to find no sync on my cable modem, after a couple of power cycles, getting nothing.
Call into support, cable gets sync while he is on the phone, I get like 2 pages to load and it loses sync again.
Tech said no outages in the area, everything should be fine, couldn’t access my modem to see if it was ok though.
Scheduled appointment for tomorrow 2-4pm.
Also, talked to the tech and said I would go exchange the modem over at the maple store and see if maybe the modem just died or whatever.
Switch the modem over no problem, Ubee junk, but whatever. Hook it all up, gets sync, run a couple of speed tests, much better btw, and then in like 2 minutes cable loses sync again.
Wait a bit, no sync, reset the modem.
Gets sync again.
Works for about 5 more minutes, try out a youtube vide in the time, etc.
Loses sync again, without resetting, it picks sync up again.
Figure I will just let it sit, had to go eat dinner, so it was there for about 30 minutes, with no data.
Come back, modem in sync, lets fire up a game see if its ok now.
Dies after 10 minutes.
Call Tech again.
Modem regains sync while on the phone, advised the tech that I swapped modems and now it keeps dropping sync. Says they can’t do anything or test anything to tell what is going on. Says I need to just have the tech come out tomorrow and they will fix the problem.
I even removed a splitter (2way) to help out the signal strength.
Here are the stats on the modem right now.
Downstream Lock : Locked
Downstream Channel Id : 3
Downstream Frequency : 717000000 Hz
Downstream Modulation : QAM256
Downstream Symbol Rate : 5360.537 Ksym/sec
Downstream Interleave Depth : taps32Increment4
Downstream Receive Power Level : -2.3 dBmV
Downstream SNR : 38.3 dB
Upstream Lock : Locked
Upstream Channel ID : 7
Upstream Frequency : 32000000 Hz
Upstream Modulation : QAM16
Upstream Symbol Rate : 2560 Ksym/sec
Upstream transmit Power Level : 53.3 dBmV
Upstream Mini-Slot Size : 4
Looks like without the splitter I am down from 55 to 53 on transmit power and receive power went from -8 to -2, which I think is better?

From the modem logs, this was the latest loss of sync.
Don’t know enough about the messages, since I couldn’t see logs to compare them from when I had my old modem.

Lasted about an hour this time before losing sync. Going to see what happens when I try to get the best signal that I can without re-arranging my entire house.
Removed the 4 way I was on and went to a two way back in. So mainline comes in, gets split with the 2 way, one goes to the modem one is going to the tv.
New readings on the modem

Gained about what I would expect from going from a 4 way 7.5db splitter down to a 3.5db splitter for levels.
