Superhub install tomorrow
As the search will bring up 1000's of threads can anyone give me a quick tolerance range for up/down power levels and also SNR ranges for the superhub as I'm getting 50Mb installed tomorrow. Just want to be able to check the levels before the engineer leaves
Thanks in advance |
Re: Superhub install tomorrow
It's the engineer's job to check the levels, but for reference the recommended range is:
-7 to +7dB downstream and the closer to zero the better At least 35dB SNR 35-55dB upstream. |
Re: Superhub install tomorrow
Thank you Qasi :kiss:
Currently on my old 2050 modem I get Upstream 38.0 dBmV Downstream 5.8 dBmV SNR 41.0 dB |
Re: Superhub install tomorrow
ive been told
-5 to +5 and 40-50 Upstream |
Re: Superhub install tomorrow
Optimum is -3 to +7
Upstream 35 to 55 Your signals are perfect, I wouldn't waste an attenuator on that |
Re: Superhub install tomorrow
Pah they did some stuff in Edinburgh that dropped my downstream levels from -3 to -8. Had a 15dB FPA on and can't find my 10, so my choices now are -8 with the attenuator or +12 without it. Urgh.

Re: Superhub install tomorrow
My only worry is that I want the 2050 leaving on as well for the next 45 days, will this effect the signal much having two on the same cable? For reference it'll be the only two devices as I don't bother with TV

Re: Superhub install tomorrow
whats a 2050

Re: Superhub install tomorrow
Modem, a bit like a 250 but with more memory and NAT capability

Edinburgh is split with many types of architecture, has your upstream changed |

Yeah, my upstream changed, but not until a few weeks after my downstream did. |
Re: Superhub install tomorrow
Engineers been, levels are (with 8 downstream channels running)

Re: Superhub install tomorrow
Those down power levels could be a little lower.
8 down channels.. very nice. would you be willing to set up a ping monitor :D |
Re: Superhub install tomorrow
Already set one up, also the 10Mb virgin Media business modem's still attached so I can compare the two graphs
