How to establish DSL connection over wireless in Fedora 22? [closed]

Here is my setup: I have a DSL modem connected to a wireless router. My friend (who is using Win 10) can connect to the wireless access point and thus is able to establish a PPP over Ethernet. I would like to have the same setup running on my fedora machine too. So I created a DSL connection using nm-connection editor.

At first I connected to wireless point and then tried to establish the newly created DSL connection and it failed. So I thought to try the same via another Ethernet cable connected from wireless router to my laptop and it worked. IIUC, there is no option to select a wireless hardware while creating a DSL connection using nm-connection-editor. By default it tries to authenticate the PPPoE connection only via Ethernet. Even if I explicitly provide the wireless MAC in the corresponding field, it doesn't pick up from there.

nmcli connection up <id> responded back saying that there is no connection available at em1 (which is ethernet). Is there anything that I am missing here or is it impossible to make DSL connection over wireless? I am more happy to provide any further details required.

Is it possible to terminate PPPoE at the router? That would make things much easier for you.

It's not possible for me because it is a DSL wireless router. The LAN out from cable modem is simply connected to wireless router in order to just have a wifi access point. DSL authentication cannot be done in that router. But I am wondering on how come there is no option to authenticate/establish a DSL connection through wireless card interface. Is there any config file corresponding to DSL connection (other than /etc/NetworkManager/system-connections/DSL connection 1) where I can provide wireless card MAC address to make use of it while authenticating the connection?

I think we're getting terms confused. DSL is always over copper, and probably never over coaxial cable. Broadband modems typically operate in one of two modes; routing, where authentication happens on the modem, or bridging, where authentication happens via a device directly attached to the modem.

Can you clarify the topology and devices involved, with as much detail as possible? I'm especially curious about the "DSL wireless router" - to me, that is a wireless router with built in DSL modem, but you're attaching it to a cable modem.

I have explained my setup in the question itself. Anyway I am repeating the same again: The internet connection to my home is via Optical fibre. This fibre optics cable coming from outside cannot be directly connected to the ADSL modem ( ). So there is another optical fibre cable modem prior to this ADSL modem so that LAN out from fibre optics cable modem is given as input to ADSL modem and it gives out the wireless access point.
