Unfortunately you are at the limit of my knowledge and I don't have any set up to test with. If a connection is made but unstable, it suggests a parameter mis-match somewhere which means sniffing PPPoE packets which I know nothing about, and I would not know how to tweak the connection either. Perhaps you could try googling.

Ah, sorry! I think that you might have misunderstood me

The connection is now stable. It works across all of the machines in my LAN.

The quirks are:
- If I run SpeedTest through the ClearOS WebGUI then that brings the connection down
- It uses a lot of resources

But as long as I don't touch the SpeedTest button in IP Settings part of ClearOS WebGUI then I'm fine


Thank you for your time and all your help
