Broadband unreliable

My broadband has become very unreliable since we upgraded to a Super Hub 3. I am on VIVID 100 and when it works its good but reliability is not good. We have had a Virgin Media engineer round twice and it is better but not fixed. This is an extract from the log for the last hour

This are the downstream levels:

Channel Frequency(Hz) Power
(dBmV) SNR
(dB) Modulation Channel ID
1 306750000 1.2 33 256 qam 14
2 322750000 1.5 31.9 256 qam 16
3 314750000 1.2 33.4 256 qam 15
4 298750000 2.2 22.7 256 qam 13
5 290750000 3 33.4 256 qam 12
6 282750000 3.4 35.5 256 qam 11
7 274750000 3.4 35.7 256 qam 10
8 266750000 3 35.7 256 qam 9
9 258750000 2.7 35.7 256 qam 8
10 250750000 2.5 34.9 256 qam 7
11 242750000 2.9 34.2 256 qam 6
12 234750000 3.5 33.8 256 qam 5
13 226750000 4.1 28.8 256 qam 4
14 218750000 4 29.6 256 qam 3
15 210750000 4.5 31.2 256 qam 2
16 202750000 5.4 33 256 qam 1

The upstream levels:

Channel ID Frequency(Hz) Mode Power
(dBmV) Modulation Channel Bandwidth(Hz) Symbol Rate (ksps)
4 25800000 ATDMA 53.5 16 qam 6400000 5120
3 32600000 ATDMA 53.5 64 qam 6400000 5120
2 39400000 ATDMA 53.5 64 qam 6400000 5120
1 46200000 ATDMA 53.5 64 qam 6400000 5120

 Do the levels look OK?

The TV and phone work OK and the data channel in the TIVO box for BBC iPlayer etc works fine.

Any ideas why the broadband is unreliable?

Re: Broadband unreliable

Hi alanp2, 

Thanks for the post! I am sorry to hear about your issues with your broadband being unreliable. I apologise for any troubles incurred.

I've tested things from here and I noticed that all of your upstream power levels are too high and will require an engineer to visit and resolve this for you.

I will send you a PM (purple envelope at the top) detailing what's required to proceed with making the booking, please respond to me there and I'll ensure this all gets booked and secured for you.

Take care, 

Thanks, 

Adam.
