Earlier in the year we were having regular dropouts with our HFC connection. Sometimes several times each day. After some direct help from a Vodafone employee and some experimentation I discovered that turning off Ipv6 on our router mostly fixed the problem (and cured some speed issues). The connection was still not completely stable though. Later on intuition I turned our Ubiquiti AmpfiFi HD router into a bridge to our mesh network and set up the unused Vodafone Ultrahub as a wired only router. This between the cable modem and the rest of our network. With this the connection became rock solid and completely stable.

 

 

 

After a month or so I got to thinking that I should perhaps put the best wired router in there instead of the Ultrahub... so I bought a Ubiquiti Edgerouter X. Setting that up was a little bit of a learning curve, but not too much. All seemed good. But then it wasn't...

 

Monitoring the connection via a ping utility to Vodafones DNS server had shown good things with the Ultrahub but with the Edgerouter, after 12 hours or so, latency went all to hell. Instead of a few milliseconds pings were over 1, sometimes 2 seconds. See the pictures attached. I tried everything with the Edgerouter, different firmware revisions... ensured it was as secure as possible as I read they were popular hacking targets... nothing made a difference.

 

 

 

Any thoughts anyone?

This looks like you have not got hardware NAT enabled on the Edgerouter. Did you follow my tutorial?

Your tutorial was the first source of information. So that's not the issue.

So for one last try I checked everything and put the Edgerouter back in around midday today. Fine to start with but within a few hours it starts falling apart...
