upstream is fine but the downstream is a little high are you having issues?

not really, some drops in the connection now and again tbh. this going to be a problem?

maybe ring tsc might need a tech

i *think* an attenuator might solve the problem.

If you are on Bromley then everything is fine.

If you are on Langley then the Downstream is to high.

PM me your MAC and I will let you know tomorrow.

I would not not know without checking the MAC, but if eth01 (http://www.cableforum.co.uk/board/members/20768.html) calls Tech Support he can let us know if the was an issue.

That is up to you, it may be just as well to call Tech Support first, as I am not in till tomorrow.

You need to speak to Tech Support as that is to high on your downstream.

out of interest when the power levels are wrong like that what's the cause? Is it a matter of getting the power level set to match the length of the coax from the green box to the modem?

If thats the case is there a reason why it would drift so much from when first installed?

We are not trained on the cabinets, we are just trained to check that the power levels are correct.

The could be many factors such as degradation of the cable or the connection working loose or even the modem at fault, which is why we then book an engineer.

If one of our Engineers read this then maybe they can give a more in depth answer.

I just got through to support....he said that it is showing running normal at his end -4
He then said it was more than likely my wireless router which was causing it to read that way? he disconneted my mac so he said! reconnected & it is showing fine no problems....I have since then disconnected my router & connected the desktop direct to the modem sam values...... What do you think?

What reading do you get connected direct to the modem because that is how we need to look at the connection, as the router will be unsupported.

If that is direct then I do not know how he can say it is lower at his end.

If you are still getting problems then you will need to call again.

you're advised to open your own thread tbh. ;)
