Can anyone tell me if these settings on my router are right for 21CN ADSL2+ Encapsulation: RFC 2364 PPPoA DSL Modulation Mode: MultiMode Multiplexing: VC QoS: UBR PCR Rate: SCR Rate: Autodetect: Disable VPI: 0 VCI: 38 Enable: 1 PVC Status: Up
MultiMode should negotiate the highest possible standard, which will be ADSL2+ if you're on 21CN (unless your line has been specifically configured otherwise by BT, e.g. for stability purposes). On most modems/router you can check what was negotiated once you are connected. 21CN will work with either PPPoA or PPPoE.
