The upgrade went ahead as planned today.

If you have either dyanamic IP or single static IP the superhub will be in NAT mode. In the case of a single static that IP address is assigned to the superhub and eqipment behind it is assigned private IP addressing, defaulting to 192.168.0.xx

In routed subnet mode NAT is disabled. The Superbhub is assigned the first usable IP in the subnet and all others are available for devices behind it. This does mean that your own device can be assigned a public routable address.

The Superhub appears to be the same standard Netgear device issued to residential customers, but with different firmware:-


Standard Specification Compliant EU DOCSIS 3.0
Hardware Version 2.00
Software Version V5.5.2R04-BU
MAC Address -------------
Serial Number ------------
CM Certificate Installed

Under basic settings are options for the L2TP tunnel:-

Cable Network Settings
Domain Name
Device Name
WAN Connection Type L2TP(DHCP)
PPP User Name *******
PPP Password ********

L2TP Server (Host name or IP)


onthe 50 Mb/s service in an area that has not yet had the upstream upgrade I seem to have odd bandwidth parameters:-

Primary Downstream Service Flow
Downstream(0)
SFID 21328
Max Traffic Rate 54600000 bps
Max Traffic Burst 10000 bytes
Mix Traffic Rate 0 bps

Primary Upstream Service Flow
Upstream(0)
SFID 21327
Max Traffic Rate 3490000 bps
Max Traffic Burst 8160 bytes
Mix Traffic Rate 0 bps
Max Concatenated Burst 8160 bytes
Scheduling Type Best Effort


The upgrade took around 30 mins due to the fact that the Superhub needs to have it's addresses statically configured and the L2TP details entered, all of which require multiple restarts of the device.

My main concern is that after they left I discovered that they have the Superhub using the old PSU from the EPC2100 modem which is rated 10V 1.2A I undersood the Superhub to need 12V 1.5A
