I have purchased 3 powerline adaptors. One for the router, one for the PC, and one for my Humax PVR. I believe they are all linked correctly. The PVR picks up the internet fine. It does not see the files on the PC (Ihave Serviio server) although it does see them and play them over wifi but not fast enough - the videos keep stopping. I cannot connect the PC to the internet using the powerline adaptor although I have no problem with wi-fi.. I go to "connect to" . I see under the heading "dial-up and VPN" "broadband connection PPPoE connection". I select and hit connect. I get a message connecting to broadband and a box asking for user name and password. I enter the username and password and the connection fails.
I don't understand the reference to "dial up". I have a fast fibre optic supply that operates broadband fine with wi-fi. I am trying to connect the PC by powerline to give me fast streaming from the PC the Humax.
Any ideas?
The powerline utility shows 2 devices in the top box:.homeplugs av, and one in the lower box: device 2.
Is this right?
