Recently upgraded to Gen 5 from Gen 4 (05 May) and am seeing some things that seem to be isolated to usage with MacOs Sierra.
1. Data usage appears to be a lot higher than expected. For example, I downloaded around 100MB of updates this morning, but the usage meter shows I used 350MB. Mac was only thing using the pipe and I waited about 10-15 minutes settling time after bootup to account for startup usage (ClamAV virus definitions, etc.). Difference in usage meter went from 6.50GB before downloads, to 6.85GB after downloads. Sorry, but I forgot to take screen shots of the usage meter.
2. Download speeds appear to be capped to around 12.3Mbps or less as measured in iStat - roughly half what's expected. There are little to few interruptions or even variations in the data stream, but I expect that being in Hughes' configuration for initial setups.
I see no high usage from other devices when I isolate them (e.g, TV, XBox, DirecTV boxes, or even iPhone/iPads), just Macs (we have 2 of them). I also have no way to measure speed on those other devices, but they appear to be ok for simple traffic within apps.
I seem to remember there was a problem previously with Macs on Gen4 that ultimately was resolved. Unfortunately I can't find the discussion of how it was solved in the new community system.
That said, I seem to recall it was something to do with the way packets were acknowledged (or their timing) in MacOS that caused multiple packet sends. This would seem to appear to cause higher data usage while resulting in lower throughput speed. Perhaps this problem crept back into Gen 5 software? - just guessing at this point.
Other than this, it seems to operating fine (other than the very occasional DNS error).
If Liz or Amanda could help me with diagnosing this that would be great.
