Frequent dropouts on new Vodafone NBN via HFC, router log shows hourly internet disconnect

I recently signed up for Vodafone NBN which is HFC. We are getting frequent droputs multiple times a day. They are irregular, sometimes we can go less than an hour before we experience a dropout, sometimes we go three hours. We notice the dropouts most when we are working from home and are kicked from remote systems, large downloads fail or are kicked from online games. 

 

I have troubleshooted the issue with Vodafone who say their system shows no drops in the NBN, so it must be our router. Whilst troubleshooting the issue they attempted to get me to connect my computer directly to the NBN connection box via ethernet, which left me with no internet (my computer didn't recognise an internet connection).

 

They also had me setup the router settings manually with the following settings, but that too led to the internet not working at all!

 

ADVANCE 

Set Up Wizards 

Select Country 

ISP Others 

Do You Want Net gear Genie to help : No 

Internet set Up 

Transfer Modem VDSL 

DSL modem VDSL 2

VLAN Disable 

Does Your Internet Connection Require Login : No 

Get dynamic IP from ISP 

DNS get Automatically from ISP 

Save & Apply 

 

After investigating the router log, I found that exactly every hour on the dot the log shows the internet disconnects and reconnects. The disconnect is only for a second, sometimes a few seconds:

Not sure if this is unrelated to our internet dropouts, as we do not experience dropouts every hour.

 

I have updated to the latest fimware: V1.0.1.78 and I have reset the router, using the Netgear Genie for the setup.

HFC is not a DSL service, but you list the D7000 modem/router in your footer.

 

What is an NBN network and is my NETGEAR DSL modem router compatible? | Answer | NETGEAR Support

 

While Netgear lists all manner of things as being "compatible" with NBN in that article, in reality this often means that the device will work as a router. You have to bypass the modem bit and use something else as a modem. It is a pity that Netgear does not make that clearer in its advice to NBN users.

 

Some NBN ISPs also have settings for HFC that need tweaking.
