Powerline and PPPoE

darcey

Hi

Can a PPPoE connection be made over Zyxel powerline adapters? I would like to connect the FTTC VDSL modem to my router's WAN port over powerline.

Many thanks.

Hello @darcey

My thoughts are maybe/probably it could work, but you would need to test it.

My reason for saying this is as follows:

• PPPoE works on top of Ethernet, see https://en.wikipedia.org/wiki/Point-to-Point_Protocol_over_Ethernet
• Zyxel Powerline adapters transport Ethernet frames by design and in practice.
• So PPPoE (PPP over Ethernet) could work over Powerline adapters, but I have not tried it myself.

If you do it, then please let us know how you get on. :-)

Kind regards,

Tony

I have some very old (85M) powerline adapters. They introduced high latency and I would not use them for a WAN link. Though I guess I could dig them out, just to test.

I have searched a fair bit and the concensus seems to be hit and miss.

I already have the pppoe link running fine over a vlan. As you say, pppoe is on top of ethernet, and powerline adapters do not, as far as I understand it, manipulate ethernet frames. I only need 80MBPS tops, so I am hoping the current zyxel (my preferred networking brand!) adapters can meet that. But I am not going to buy any equipment until I know it will work for a pppoe link and also have some idea of latency to expect. Currently the connection is good at 5 ms.
