I recently upgraded to 500mb FTTP here in the UK. My VR2100 (latest firmware) when connected to the ONT only gives me 250mb over a wired CAT6 connection however the Plusnet(BT) hub supplied gives me over 500mb when connected the exactly same way. This is without any QoS settings applied.

What is going on? Surely the WAN throughput on the VR2100 cannot be so limited? Anyone have any ideas?
