This is still an issue in 2025 (900mbps + with ISP or PFsense router, 725 with R3 ).
I don't get how a router you are charging nearly £300 can't do basic features such as 1Gbps when using PPPoE.
Why can't it?
The idea that the fix is to offset handling of PPPoE to a more capable device is laughable.
The basic router I got from my ISP that can't even do QoS can handle it.
Is there really still no fix ?
