I know VM have probably had increased demand during the last 3 months but I note increased dropouts or lag on my network with the identical setup.
For example, a digital radio in the kitchen often drops and reconnects, casting (via Chromecast) now.tv to my TV is almost unusable. Also, playing recorded programs from Lounge Tivo to Play Room Tivo also occasionally drops and is laggy.
Previously, all this appeared to be reliable - well I never noticed an issue.
Here are my Down/Up levels - are Up too close to 50 (I see VM still haven't fixed that 1/10 error) ?
BQM and stats look ok - except the down RS error counts are very high - this could just be "historical.
So switch the Hub off for 5' than back on and look in to see that the error counts have all reset to 0. Then check them every hour or two for the next few days to see if they start reappearing - they shouldn't (particularly the PostRS ones). If they do - its likely that there is noise getting into your connection somewhere.
