Weird V+ online light + 20meg problem

[Middlef]

Hi,

I've had a V+ box, telephone and 20Meg internet installed last week, they layed a brand new cable from the street to my house too.
Here are some details from my cable modem :

Downstream Receive Power Level : 4.4 dBmV (varies throughout the day between 3.5dBmV - 5 dBmV)
Downstream SNR : 38.5 dB (this one is pretty much constant)

Upstream transmit Power Level : 61.0 dBmV (this one is constant too)

The problems I am experiencing are as follow :

V+ box
On demand services are not working.
The 'Online' light is flickering, tried rebooting etc which doesn't help.
I checked the setttings, and it appears that I don't receive an IP address since the address is 0.0.0.0 which is why the light is flickering.

20meg XL internet
I've been using the internet quite extensively over the last week, I have great speeds (2400KBPS so its maxxed out) but have had several outages (the ready light flickers) throughout the week for several hours, some days it has been perfectly fine being online for 1.5-2 days at the time having downloaded approx 300GB in my first week.
There has been some maintenance/faults in the area close to where I live but from reading all forums my Upstream transmit Power Level is too high.

I have two different engineers comming round soon, one about my internet issue and one to check the V+ box.

My questions are :

Does the 61.0 dBmV upstream power level have an effect on both V+ and my internet disconnection problem, can it be related?

When i'm online, my pings are low and I reach the speed cap without a problem, therefor i am reluctant for the engineer to make big changes to my setup, will adding attenuators mess this up?

I am determined not to get fobbed off by the engineers, so if you have advise on what to ask him or what I should look at while he is here it would be greatly appreciated!

Thank you.

Yes, the upstream is required for the V+ box talkback (flashing light / on demand issue) and for the upstream of your modem. 61dBmV is far too high for the modem to be trying (I think it's basically the highest power upstream that the modem can go), which means a low upstream return path. A blatant signal issue that the engineer should spot pretty quickly.

Is such a problem easy to sort out for the engineer or will they have to dig up the entire tarmacced street for this problem?

Upstream transmit Power Level : 61.0 dBmV (this one is constant too)

The Upstream is way to high and the engineer will adjust it in the cabinet at the end of the road and it should alleviate the problem.

Excellent news, I will post my experiences tomorrow after the engineers have visited.

OK the weirdest thing happened now,

I came back home today and now I have the following settings :

Downstream Receive Power Level : 8.3 dBmV
Downstream SNR : 39.5 dB
Upstream transmit Power Level : 44.0 dBmV

The V+ box has ondemand now and internet still works, I can see in the log that my modem resetted at 11:04 this morning.

What do I do now?? I have two engineers coming round tomorrow to check it out, obviously someone or something must have changed something to get my signals changed today.

I am worried about my Downstream Receive Power Level : 8.3 dBmV, this used to be between 3.5 - 5.0 throughout the week, but has gone up into the 8.0-8.5 range now, is this normal?

Thanks!

The downstream signal has increased/improved and the upstream is very very healthy. I'm not sure if they'll charge you for a callout if the problem no longer exists, one of the guys here will be able to fill you in no doubt :)

[Middlef]

yeah I am very happy with the improved SNR and upstream, my only worry is the Downstream Receive Power Level : 8.3 dBmV, since the stickied post in this forum says that a power level of 8.0 should be cause for worry, or has this changed?

So long as all is working as it should be that's absolutely fine. What's in that post is quite conservative.

I just got off the phone with customer services and cancelled both engineers.
The scottish chap told me that the downstream power level should be between -4dBmV and +12dBmV, so my +8.4dBmV should be fine.

Thanks for the help, and if anything changes I will keep you all posted.
