Re: Cambridge CB5 UBR over utilised!
We could do with the event log (CM-MAC address to be obfuscated) so that we can assess the effect of your poor downstream power level.
You speed test suggests your problem lies with the downstream side and this is supported by the low downstream power. Has your power always been at this level? Are you located a long way from the street cabinet?
Is there an attenuator on the back of your cable modem and if so, what value attenuation?
