I had an engineer come out early this week. On the last visit they forgot to change one of the old connections. The changed this and now the broadband seems to work a lot better.

Anyway, they suggested a internal rewire, but did not state whether the the cable will replaced from the brown box, outside the house,  all the way up to the router or just the part of the cable which is in the house.

I rang up to enquire but VM staff were not able to tell me anything.

Can you please look into this and find out what part of the wire will be replaced.

Thanks

Hi Javedsaleem 👋🏼.

Thank you for posting and welcoming you back onto the community forum 😊.

It also depends on what needs replacing internally.

I can have a look into this for you, so I can further investigate I will have to private message you. 

Please watch out for the envelope ✉.

Thank you.

After convincing VM to rewire the inside of the house, the end result, is significant a improvement in the quality of the broadband.....but only after I had constantly requested it.

Errors still appear, but are less. I think the outside needs rewiring and then we will have no more errors.

I can across this post, which suggests old infrastructure can cause issues.....

You would think VM Staff and Engineers are competent in the job they do.....alas that is not the case.

I am a Novice in this area, but determination, led me to identify possible causes and suggest solutions that made a significant positive resolution.
