Virmin saying noise on cable line

Hi all,
I had a VM network engineer come to my house yesterday as my cable connection is intermittant - keep having the line dropping connection.

Line coming in from the road to the house - OK
Line from outside brown box on wall to inside white box - OK
Router connection and router - OK
all above was checked with his handheld device which he plugged the cable wire into.

When he was looking at the cable connection inside the house, he seen my splitter (Labgear 2 - 24000) and my VU box and said that the splitter is not a VM splitter and said as ive got a "dodgey box" it is causing noise on the line which in turn is causing intermittant line outage.

He showed my some figures on his phone with SNR and SNG (i think) and both were showing around the 27/28 mark. do not know what either mean.

He said that VM monitor noise on cable lines and if it is not within their parameters, they come and block the line at the green box on the road.

I am only signed up for Internet with VM. So since last night, i have disconnected the splitter and put everything back to how it should be for the time being.

can anyone shed some light on this?

TIA

Why would u let a engineer know u have a dodgey box ? R u ok in the head ?
 
A vermin engineer wont give a s**** about what you are running in the house, but always better to remove any boxes..[ stops them blaming the box ] and then they can find the real issue ..Whats that saying..." what the eye doesn't see...the heart doesn't grieve "
 
Lol well put it this way if u went into their shops and said i would like to have one of them dodgey box instead of your normal boxes do u think they sell them ? I don't think so . Even tho if they did they would make a profit out of them . They r illegal mate and all u need is a jobs worth engineer who phones the police while he is in your property and u would be stuffed .

Yes, he can't find what's wrong with the connection so he's given you an excuse and pointed out that your illegal equipment is probably causing the problem, which it isn't.
He then issued a veiled threat that VM will cut the connection if you continue using it, which they can't monitor.
now you have removed the splitter and just have the router plugged in, perform a test on the router power levels to see if he's talking bullsquirt:
on the bottom of the router is a 'settings password' write it down
open a browser window on laptop and type 192.168.0.1, click enter
use that password to login to the router
click Advanced settings on the left, then tools>network status
this opens a new page, click Downstream tab at the top and it'll show all the data in a list
copy and paste it here

After the test, switch router off at the wall and reconnect the Vu and splitter etc and power everything up, after 10 mins of use, perform the same test again and i'll check the differences

You wouldn't be stuffed at all there not bothered about little fish sky and virgin engineers all know about dodgy boxes how many engineers actually have legitamit boxes

The boxes are not illegal to buy just to use to watch pirate TV but if used for freeview then no issues,I would still have removed it before then engineer called.
 
to all the people saying along the lines of "why leave the equipment in the room etc", it is not illegal to own and use a VU+ box or any other box like that. The potential illegal side is what/how you you use it. Im sure not everyone on here is whiter than white.

The previous 4/5 occasions that VM have visited, none of them have said anything about the box etc

Just to clarify, the box was disconnected and the wire left on and it was all put to one side. I connected everyting how it should be before he came. It was only when he seen the splitter and the wire going from it, he then said all that about a "dodgey box"

I forgot to mention, he also put on a "forward path attenuator 6dB"

All these SNR 35 are low, should be above 38, a lot were 36 and those may be borderline, 34.5 is absolute minimum, so 35 is very close to it. 38 is normal, over 40 is better
try it with the other equipment plugged in

if the above is with the box attached, they are too low, channel 12 is showing SNR of 34
the power levels are ok-ish but could be better, there's a few -4.5's and a -5, the parameters are -6 to 10, so somewhere in the middle of those, around 2 would be ideal

take off the attenuator and see if it's better or worse
