I have recently had a problem.
I upgraded my M500 to 1GB and am not getting any think like the speeds that I should and am just getting over 535mb
Strangely my upload speeds are 50 to 52mb so in the right provisioning band for 1GB product and they if I am correct in my thinking on DOCSIS 3.0 (and the D/L on 3.1)
I have had two engineer visits and still no further on, equipment and FTTP are okay
I am using a HUB4 which has been changed, but no change in speeds.
The provisioning appears to be correct and the levels are ok
My question is this, has anyone got a HUB4 with a wideband -3db attenuator that is getting 1GB+
On rebooting my Hub4 the QAM starts at 4096 and within 20 minutes drops to 2048, my speeds never seem to go above 550mb(measured direct at the HUB with 1GB nic and cat6 cable. (this happens with or without the attenuator in place)
I have ruled out everything else and am coming to the conclusion that it might be something with the attenuator or a miss match from the cabinet.
Unfortunately there is no one else on my cabinet on 1GB so can't even find out if it is a local issue which is starting to get frustrating
Any help or idea appreciated

Are you testing using the samknows real speed website?

we have tested with the engineers handheld test meter and a clean boot linux / windows installations all showing the same results +/- 5mb directly to the rear of the modem
Sam knows does not work in modem only mode
I have a 10dB Forward Path Attenuator fitted to reduce my downstream power levels, and I'm on Gig1, so you should be able to rule that out.
So just to confirm are you saying that the engineers couldn't get more than 550Mbps on their test kit?

yes, the speed tests were all agreeing with each other..
Is your attenuator a wideband one ?

so a bit of further reading
Attenuator - a plain attenuator will weaken (attenuate) all frequencies, reducing the downstream signal strength, and causing the upstream power to increase (the modem needs to "talk" louder).
Forward path attenuator - weakens (attenuates) the high frequencies used for downstream only, without affecting the upstream frequencies.
wonder if this is the problem ?
Open to suggestions

Maybe VM have a router doing rate limiting somewhere.
is your Max Traffic Rate in hub settings showing the correct value?
have you tested without your router and have tested with PC to the hub in modem mode?
