Hi There,
I have a Mikrotik Audience - the connection is L2 Bridged TP-Link Archer VDSL -> Mikrotik Audience (Router/ Firewall) and I'm having serious bandwidth bottlenecking issues at the Mikrotik device.
Ideally I would like the Audience to do everything Layer 3 but I am having significant issues with some type of throttling with PPPOE on the Mikrotik, If I just connect the Mikrotik downstream with the TP-Link handling L3 termination then the issue doesn't occur. Ideally I'd like to avoid two layer 3 devices inline unnecessarily but I cant get the PPPOE to work on the Mikrotik without significant throttling, link is tested at 100/40 with PPPOE on the Mikrotik I get 70/7 max. I initially assumed some type of auto-negotiation issue but haven't been able to resolve. Initially I had been able to get it to a point of being bearable with the stable software but I've currently switched to v7 and the results are obvious. Is there a known issue with PPPOE or is it recommended to rebuild from scratch instead of upgrading to v7? I would like to use Wireguard so I don't have the option with the old software so I'm starting to get sick of working around this problem, was going to upgrade to RB5009 so I need to figure this out sooner or later.
I have confirmed all settings on the upstream device are fine, MTU has been checked and confirmed OK, no queues except default. I have holidays next week so I am looking to connect a Cisco or Juniper device in place to fully confirm but I just wanted to reach out in case there is something I am missing or there is a known bug with PPPOE?
