Re: Upstream Channels

The problem I have is the Upstream Power Levels.

As an engineer I know that when a system is setup to work within a range, whether that be movement, pressure or voltage the ideal setting is the mid point between the lowest setting and the highest setting. I know we cannot always work at the 'ideal' point but the settings must be kept away from the limits.

My Upstream power levels are always hovering just shy of the upper limit meaning that any kind of twitch / problem in the outside circuit has major effects on my broadband.

As you can see from this thread, the problem has already been notified.

https://community.virginmedia.com/t5/Speed/Speed-reducing/td-p/4250793

Can someone from VM do something to get these Upstream Power levels to a reasonable level please ?

Re: Upstream Channels

You are correct. In fact you will probably find those upstream levels go even higher as temperatures rise today.

Now that the original fault on your cable segment has been fixed you should be able to get a tech out to correct that.

Re: Upstream Channels

This is getting beyond a joke now.

@John_GS can you get something sorted please. I am fed up with being told there isn't a problem.

Re: Upstream Channels

Hi MikeRobbo

 

Thanks for coming back to us, we appreciate the frustration caused with the upstream levels issues you're having.

 

Remotely checking today it is showing that all power levels are within spec. It is showing green across the board and no area faults are affecting you.

 

Has anything changed your end since your last post on Saturday?

 

Kind regards Jodi

Hi Jodi

thanks for the response.

The Upstream Power levels are ALWAYS hovering around the max of 5.1 but never go above it so will always show green.

As you can see the power levels are 'in the green' but the quadrature amplitude modulation on 3 channels is out of spec, and the upstream slows down to the speed of a drunken slug with a limp.

It is getting very very frustrating because every time there is a blip in the system my internet becomes unusable.

As you can see the power levels are 'in the green' .

Does anyone actually look deeper into these kinds of problems rather than saying the voltages are in spec so it must be good.

I have now had 3 tech visits to look at this and each one has said it needs either adjusting in the cabinet of transferring to another tap and as far as I am aware this hasn't happened.

What are VM going to do about this problem ?

Re: Upstream Channels

Hey MikeRobbo,

 

I can see that an engineer would be needed to fix this for you, I need to send over a PM to pass account security, then we can get the engineer visit booked for you.

Well, I got a call from the engineer just before 08:00 saying that she was at the street cabinet checking things out and changing the 'Tap' for my broadband & TV.

That done she came to the house and had a general check of the indoor circuit, she changed the 2 indoor splitters and put new end fittings on the cables. She then did noise checks from the Hub3 to the street cabinet and said it was very noisy. She then checked from the first splitter on the indoor circuit back to the cabinet with the the same very noisy result.

Next was outside to the T (triangle box in the pavement), she lifted the little cover and the hole looked be blocked solid with dirt but it actually turned out to be a lump of silicone sealant the size of a tennis ball, once that was out of the way it was evident that the cable had been repaired inside the box.

A re-pull has been arranged for sometime on Monday. I am happy that a tangible problem has been found and hopefully once the new cable from the cabinet has fitted the problems will be gone.

Well done Victoria.
