After my recent posts about my OpenVPN sessions going from near linespeed for a couple of years, to now struggling to hit 5MB/sec on multiple providers I did some digging. I get 1000s of pre and post RS errors, a number of T3 and T4 timeouts and other issues, as well as random 'grinding to a halt' on the actual cable line itself (i.e. sans VPN).
Our power levels have always been around 0, which is nice. I just logged into the SH2 and noticed they're now in the region of -5.55 dBmV. We have 8x QAM256 downstream channels and 3x 64QAM upstream channels if that's any use.
As we're on a new build (and rapidly expanding) estate I imagine lots of other installs have taken place and either the extra load has changed our signal levels (?) or maybe we've been pushed to a different place in the cab while someone else was being installed.
Is it worth booking an engineer to have a look? I know Seph's guide recommends -3 at the lowest and even VM spec stops at -5. Just wondering if it might improve things that's all. We've been selected for the upcoming hardware trial so I thought it'd make sense to ensure everything was as it should be before taking part.
Worth a punt or not worth bothering about? I've attached the downstream and upstream pages FYI, not long after another reboot. Thanks in advance.
