Internet drop outs. Upstream dBmV 31

ASH64
On our wavelength

I am having poor connection issues ,

Internet dropping frequently and I have checked my logs and shows which I believe is my upstream power levels are lower than it maybe should be ? 

Lowest is 30.8 highest is 32.2

35-49 dBmV is more the normal upstream power level for the Hub to transmit to the street cabinet.
However if the modulation mode for 3.0 channels holds at QAM 64 the connection can work on lower numbers.

Try a speed test of the Hub ..

The speed at the Hub should reflect your subscription.

The Upstream Power levels is the transmission level from the VM Hub to the street cabinet.
Perhaps you are quite close to the street cabinet so the Hub is not having to work hard to deliver a satisfactory signal.

Too many downstream errors, but the figures are accumulative since the hub was last power cycled. So please turn off your hub for a short period, this will reset the counters, then post a new full set of stats after about two hours. This will indicate the current line status.

Hi ASH64,

Thank you for your post, sorry to see you've been having some trouble with your broadband over the weekend.

I've looked this end and can see that there was some instability with your speeds and general connection over the weekend, especially on Friday. However your power levels and speeds seem to have levelled out since then.

If you have been able to reboot your Hub on Sunday since Tudor's advice, can you please let us know how you've got on since?

Thanks 😊

Beth
