What the?

12-07-2018.png

 

 

 

 

 

 

 

 

Got back from work today and noticed a few things on my BQM

Minimum latency dropped at 2:30ish (im not complaining)

Huge 100% packet loss blocks (.608 not playing well with think broadband's quality monitor?)

 

But the main issue is network logs...

All of this happened on the same day

Re: What the?

Hello risc19

I am sorry but looking back there was a little bit of noise on the area upstreams and it may of accounted for the entries in the log. It seems to be much better now, the hub is reporting all levels in spec with no errors. Incidentally we are already aware of an issue with BQM responses and 608, although it may be frustrating it does not seem to be performance affecting.

Thank you

Nicola
