51 is near the top of the acceptable range, VM will tell you there are many connections with higher levels (~54) that are working just fine.

All your other data looks good - what issues are you actually having?

Have you got a BQM running and what do the Network logs look like?

[SonarUK]

no problems right now, but the 24th was a little sketchy for the day (the worst its been within 3 years) so i created the bqm.

my area just an upgrade that forced all the hubs "smart wifi" back to enabled unless opt-out through email.
this didnt bother me as im in modem mode.

but i thought ide check my hub stats to see if that did bother me at all

BQM is clean

Hi SonarUK,

Thanks for posting,

As jbrennand your BQM looks like, and the upstream channels are at the high end, but still within spec.

If you do start to experience issues with the connection please let us know.
