@Solla-topee thanks I first wanted to use only one ap for easy management that is why I did not want to connect the powerline after the router then I found that the power line does not change the Mac...

Can I use Powerline Adapters with PPPoE and will it be reliable It only needs to be 100mpbs max even 60mbps is enough and what models support it? I could not find such information. I want to connect...
