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

All the levels and stats look fine, the line has been tested, the router changed the only thing I can think of is that there is an incorrect provision somewhere on the network as the router has been changed and is showing the correct provision

Hi @ST4, thanks for your reply and I'm very sorry to hear that.
We have exhausted all of our checks at the moment and there is no reason you should still be getting just 500mbps or under. I'll leave this thread open in case you need our support until you disconnect, or we can provide any further support.
Sincere apologies.
Many thanks
