Modem resets, timeouts, tlv-11 errors... Going on 3 weeks now

This seems to be a common issue now with Phoenix users and the service. I called into support when my modem was regularly resetting (N450) 20 times a day (not kidding...it was bouncing ever couple minutes).  Call into Support and 'Oh there's a maintenance going in your area that's why'.  They said the would re-provision the modem after it was complete to fix but according to the field tech who came out today never did.  4 phone calls (3 dropped with no call back or message) and I finally get a tech out here. 

According to him...signals and everything are fine. Supposedly the NOC or whatever they're called doesn't see my modem on the wire at all yet can send reset signals to it. The modem DS/US lights never stop blinking now and are just constantly flickering (this started back when that 'maintenance' was happening).  They found nothing wrong, said signals were good, yadda yadda yadda. 

After he went outside and came back.. this is how my levels are looking now.  Using the Power Level guidelines from Netgear...my signal is piss poor.

Downstream power level (Received power)

The specification for downstream power level is -15 dBmV to +15 dBmV for cable modems. A value of -7 dBmV or worse indicates a poor downstream signal path. An installation technician would aim for a value close to the optimal 0 dBmV, but a good cable modem is capable of working within the broader range of -10 to +10 dBmV, provided the downstream Signal to Noise Ratio remains good enough. Additionally all downstream channels should be within a +/-2db window with respect to each other.

Upstream (Transmit)

The upstream value should be between 40-51 dBmV (depending on number of channels bonded). A value within the range +40 to +51 dBmV is within spec with the low to mid 40's the most common. If the cable modem is going offline, and the upstream signal strength is at or above +50 dBmV when being bonded with 3 or 4 US channels, then a poor upstream path is probably the problem.

This is a 6 or 7 month old Negear N450 modem/router all in one. It's been rebooted, unplugged, disconnected and let sit overnight. Factory reset, rebooted, re-provisioned, whatever else they do.  There are no splitters either. Cable runs right from outside through the attic down the wall into the modem.
