Done a reset this morning as i noticed general lag with the net, good to see it working again.

Although this is the 5th time in a week i have had to reset.

I think you're confusing power levels with the channels/frequencies.

The power levels are adjustable at the green boxes where there are different attenuators/boosters to hook your cable onto depending on how far away your house is etc.

The ideal power level is 0 but -3 to +7dB is generally recommended by Virgin I think, the power level will fluctuate under different temperatures so it's impossible to have bang on 0dB all of the time. I think the DOCSIS specification for most modems is +/- 15dB but you might get problems at either extreme.

no. every engineer that has came out to me has said different areas have different power level ranges. maybe it's another lie from the engineers
 
Still might be some differences with the old Telewest and NTL regions but obviously have to be within DOCSIS spec.
 
I suppose houses situated closer to the green box may be more tolerant of weak signals due to there being less cable exposed to signal ingress/egress but even so they should be targetting 0dB at the modem tuner regardless of distance.

Also, it's better to have a signal on the strong side because weak signals are more susceptible to interference, that's why a lot of the engineers put people on the higher taps and attenuate the signal at the house (that and probably laziness :p).

I'm getting Virgin installed next weekend, but I'm unsure of how many cables they'll need to run. We are getting

2x TV
1x Modem
1x Phone

From the street to the house I believe is 1 cable, then they install a wall box, drill the wall then put another box on the inside.

From this internal wall box each device has its own cable yes?

Can you have this internal box positioned where you like?

We have a utility room in the centre of the house where all the comms gear is stored and I'd like the modem there.

Also the TV locations are on the wall either side of this room, see picture.

Will the installer allow this? I'm pulling the floor up to route the cables.

No the internal box is not for every device in the house - only for that room. There is one external box then they run along the external walls and then into the room it needs to go into (or up the wall then in if on the first floor for example).

Thanks Duke

The yellow in your diagram is not an external wall, its a semi :(

If I have the floor up think the engineer will be happy to run it under the floor along the path you describe?
I'll lend him a hand pulling cable or time depending this week will put some pulls in for him.
 
They won't put it under the floor but if you have a good engi he will leave you with enough cable to do it yourself. Ours did.
 
Yeah they wouldn't normally but as said if you have a good installer (tea and biscuits often help :)), then they can be flexible. Usually it is staple gunned to the top of the skirting board - they did a tidy job of ours although it was over ten years ago :eek:
 
Peak time youtube loading times strike again. Been fine for last 2-3 months at peak times but last week or so back to videos completely stopping and being unable to watch much at all.
 
Well even though the power levels are what they should be... the latency issue is still there.

Pretty much this. the Newcastle region is a whole different ball game according to each engineer I have spoke with.

Still, I'm in a non congested area so my 120mb runs happily :cool:
 
Okay so the latency is still active but it's settled down a bit:


I am home from work and browsing etc is all fine, speedtest.net shows:

So browsing is fine as is streaming.

Pingtest.net verifies the high latency that TBB graph above and is reporting the following. I ran the test 3 times at each stage.

Before rebooting router (WNDR3700):

After rebooting router:
90608608.png


After rebooting SuperHub (v1):
90609135.png


So rebooting the SuperHub restores normal latency. Pingtest,net ping values are always higher for me for some reason even though pingtests everywhere else shows <20ms, never understood why but you get the idea :p

In a few hours I'll check TBB again and as before, the graph will be back to its good usual low latency results.

I had expected a graph similar to yours after setting up a monitor last week. Shocked to find it is actually pretty good:

Sure thing :)

The engineer has just been and adjusted the levels. Here's what it looks like now:
A much better result!

I will keep an eye on it over the next few weeks and see if the high latency issue returns.

thanks for the update. Have posted over on the VM forums as i won't be able to call until the weekend, over the past 2 days i have had to reboot the SH several times and now my 120Mb has dropped to around 30Mb - 40Mb :( ... plus side had an email from ocuk saying my asus rt n66u (RMA) will be delivered tomorrow so wireless will be much better :cool:

Thought it was just me...

 
I've just had virgin cable installed in my new house with a sh2 are there any advanced setting I should change to make the connection better?? I play bf4 so want it to be good for that. Thanks

I've got the 60mb line
 
Just wondering what affect the power levels have on the connection?
Mine are high judging by what people have put on here, but i have no issues as i know of.
