modem decides to reboot a lot and upstream power fluctuates between 44 and 54 dbmv -

This question is about "modem decides to reboot a lot and upstream power fluctuates between 44 and 54 dbmv", with Time Warner Cable internet and apps. on our recent setup connection we have some problems.
The connection to the twc network is not always very stable. I do not know the pattern for now it seems very random.
Can be stable for days and then only for a couple of hours.

Since i noticed that the upstream power fluctuated towards very high when the connection was rebuilding i am keeping track of it a bit.

this is the manual signal power over a couple of days... ussually i check when the connection drops so .... and after the connection dropped the signal will quickly return to the 45dbmv values.

I would apreciate if someone could look at it from the other side of the line.


A bit of history... the previous tenant had a stable connetion to about 2 months ago and then the cable signal kept on dropping randomly that rental modem did not reboot but just did not reconnect to twc anymore it needed to be manually rebooted. She called a couple of times about that but did not receive an answer of what the problem was.
About a month ago we moved in and used the rental modem first and soon after switched to a bought modem, currently a SB5101NU-2.11.0.0-GA-04-597-NOSH had a ubee modem fro a while but that had problems with the wifi reception so we got a standalone wifi router.

the cable from the twc locked box on the side of the house has not been touched in a long time and it is one run of cable to the modem. No splitters just directly connected to the modem.
