Could one of you who's more clued up about this than me tell me if this is good or bad?
Been running the monitor for a few days now on our connection and it generally seems to follow a similar pattern to the above in the previous days as well. This is from the SH2ac directly at the moment, not in modem mode. Whether that's what's causing the issue and a better router would fix it I'm not sure.
I would have thought the latency spikes would be when the connection is getting used, but they seem to be fairly regularly spaced, even through the very early morning when the only devices connected to the router are phones/tablets in standby.
I haven't noticed any connection drops or slowness and generally I'm happy with the connection so far, but that graph does seem to have more regular latency spikes than some that have been posted here.
