Posted power levels are within the recommended range, although you have only posted the first half of the downstream figures.  There is a second set of figures further down the page with headings:

Channel Locked Status RxMER (dB) Pre RS Errors Post RS Errors

If you could please post those as well.

Those figures show a large number of Post RS errors which is not healthy, unless they are a historical build up of old errors.

Has the hub been restarted recently?  If not it might be worth doing that, to rest the error counters. Wait 24 hours and then post the section of the power levels as above that shows Post RS errors.  Pre RS errors are not an issue, they get resolved by the hub, but if the Post RS errors rise rapidly after a hub restart then that would indicate a fault on the line that needs an engineer to take another look at.

That is not a healthy looking log.  If the Post RS errors are high again tomorrow then that will provide ample proof of a fault to show the next engineer that visits and hopefully help him track down the cause.

i rang through to virgin media, explained the issue, but he said on his side everything is green and not showing any issues.

so he will not send me an engineer or even  a router replacement.

problem is websites taking ages to load up and ocasional loss of sync errors.

this never used to be an issue and effects all devics wifi or ethernet connection, loading up google.co.uk can take up to 1 min on a strong wifi cnnection or ethernet connection.

they seem to only care about if you are getting the speed you pay for and if at the most your power levels are good.

Hi Chris676,

Sorry to hear about your broadband issues and that you're keen on getting it resolved. 

I'm going to send you a Private Message so I can look at this for you. Please reply back to it so I can help.

Thanks,
