Modem Random Reboots Daily - Time Warner Internet

#1
This question is about "Modem Random Reboots Daily", with Time Warner Cable internet and apps. Since the week of Memorial Day, I have had pretty much daily, sometimes multiple times a day, internet drops. They are random, and only lasts for a few minutes. I normally would just ignore this and deal with it, but, the drops are now happening during the normal work day hours, and, I work from home, so this is cutting into my productive time. I managed to get into the modem logs and saw this:

Upstream 1

17.80 MHz
57.00 dBmV
DOCSIS2.0 (ATDMA)

Instead of the normal 4 upstream channels I was used to seeing, with power levels in the mid 40's, I just have 1 channel with power levels in the high 50's.

My modem is fairly new, Arris, and all of the cables and connections in the house are fine; I do have a splitter (which I cannot get rid of), and a tech earlier this year installed a power inserter, I think that is what it is called, because my upstream speed was so high, and after installing it, the upstream power went down to the low 40's, but its back up again. Before I call for a tech visit, can someone check out this log for me? I'm not very techie, so not sure exactly what to look for.
