RBS50 slow when connecting direct to Openreach ONT

Hi all 

 

So I'm based on the UK and have signed up to Vodafone on a 900MB line FTTP, when I connect the ONT to the vodafone Router to my Orbi (put into AP mode) I get the full 900 mb speed as expected.

 

However, when I connect the Orbi direct to the Openreach ONT modem directly and enter in the PPoE details with username and logon, I notice that the speed performance drops significantly to 500-600mb (even though I'm using the same cable that went into the Vodafone router but moved to go into the Orbi).

 

Any suggestions / help? 

 

Thanks

    Let the ONT handle the PPPoE connection. Leave the RBR in DHCP mode while in router mode with the ONT.

      Is that possible? Was speaking to Vodafone and they said the router connected to the ONT needs to connect via the PPoE. Hence they gave me username and password for orbi to use.

      Or is there a way to tell the ONT the details?

      Thanks

        PPPoE has never had good performances. Even on Orbi. 

        Kind of odd that the ONT isn't able to do the PPPoE configuration. I would think the ONT should be able to handle this however possible there services require separate ONT and Router configuration and router needs to handle that. Does the ISP have a separate router system they support of there own? Something to try there router and see.
