I recall discussions about your service in a previous thread some months ago, and I remain at a loss here.
So:
- the loss of 7.5dB of signal IS suspicious, if you haven't changed any wiring off the pole lately, node balancing tends not to shift signals that much. The more important question: is that number stable or is it randomly jumping a 5-10 dBs from one hour/day to the next?
Let me repeat that: 0 dBmV RxPower is not perfect - it's only perfect if your house happens to be the ONE in the middle between the node and the farthest point on the strand. Only one house on an entire node can have +-0 dBmV - but you could always move your house around a bit if that's important to you
- how much uptime (days) did you have with the modem when you looked at the correcteds/uncorrecteds? It's really not that much, even with 48hrs of uptime. DS #5 with its uncorrectables is a bit of a worry - it could be the cause for RCS-Partial service (loss of 1 or more DS channels due to RF isssues), but compare that to my own (very very very trouble-free) : my worst DS channel has 15,000 uncorrectables - but for 120+ days of uptime.
- your log is going back rather far (8 months) - which is good: not a whole lot is happening with your modem. The number of T3 timeouts and DS sync-losses is absolutely minimal for that amount of time, and RCS-partial-service didn't occur that much either - but the web-UI version of the log doesn't show the repeat counter (that can be read via the SNMP MIB, but that's only accessible for D2 modems), so this verdict can't be final, only indicative.
- no need to exchange the TM802 for a TM822 : there's not enough to be gained - only the additional battery life.
So:
how often do you experience sluggishness with the connection (tested from wired, not wireless I'll assume?)? Or does it only occur shortly after the modem has booted, and goes away?
Do the RF values change while you're having troubles?
There's not a whole lot to go by here, and the logs have probably told me already more than CV's service rep and regular (non-OSP) techs will ever be able to turn up.
