Removal of Old Wiring

[aird]

Hello,

Not sure if this is the correct area so feel free to move.

I've recently moved into a new house and have brought VM broadband with me, but the previous owner also have VM everywhere so as you can imagine I have cables running everywhere.

However, as I'm just taking broadband alot of the cables are not needed and a bit ugly as they aren't connected to anything just lying around.

I'm looking to see if I can remove these without causing any hassle to my broadband connection.

This is the current set up. Cable 1 is the new cable i received when moving house. This I want to keep.

Number 2 is what I want to remove and take the cables away, I won't be touching the boxes on the wall. Just the silver one on the skiting and the cables connected.

Thanks in advance for any advice.

The only issue you have is that signal levels at the property are balanced for the existing loading (the cabling you have connected). Removing cables & splitters will change that balance, which could affect the performance of your Broadband service. When techs make alterations like this they will test signal levels & then open the street cabinet to rebalance for the new loading.

From the picture it looks like you have already removed the splitter, so you will have to see if there are any performance issues as you have it now. If performance is affected then call it in as a fault, & a tech will be sent to rebalance the levels.

So are you thinking that I should put the shorter cable into the larger white box and replace the 2 on the left with my new cable?

I've not experienced any issues at the moment *touch wood* but I've not really had an extended go on anything internet heavy as I'm stuck decorating 😭

Looking at the pictures you provided, it would seem that your hub is connected directly to the VM box, I assume that the cable on the right which isn’t connected is the old one which was connected to the VM box, yes?

If that is the case, then yes, you can safely remove everything else and dispose of as you see fit.

[aird]

Yeah, that's correct. My hubs going into the wall socket.

I'm not sure which cable was which, as they were just lying on the floor when we moved in. I assume ones tv box and other hub.

[Tudor]

All the cables and splitter, marked 2), in your picture can be removed if you are only having broadband and no TV.when the hub is up and running provide us with some stats, instructions follow, and we can let you know if the signal levels are ok. If you are having TV let us know.

Hopefully all looks ok.

Your downstream power levels are a bit high, but it doesn’t seem to be causing too much of an issue. Ultimately forget the raw stats, are you getting the service that you expect? If so then fine, it’s easy to get too obsessed with numbers, or indeed what people think the levels should be.

[aird]

Yep, I'm getting my service.

Tbh I don't even know what the numbers mean 😅

About the powerlevels, in my previous address the engineer installed a 10dB Wideband Attenuator which I haven't reattached.

The old address, which was rented, it had an existing cable going into the hub. Since I got a new cable, I didn't put it back on as I assumed it wouldn't matter with new upto date equipment.

[Tudor · Accepted solution]

A 10dB attenuator will bring your downstream level to the optimum level. I should try attaching it and post a new set of figures. If it impacts your service you can always remove it.
