Hi all,
I have a TL-WPA8630 KIT and I have this network configuration:
ADSL Router(Vodafone station) ---- TL-PA8010P ---- TL-WPA8630 --- PC
On this PC I have various DLNA server (PLEX, Mediatomb, Rygel) and also SMB setted.
When I am connected to TL-WPA8630 via ethernet or via wi-fi with others devices (smartphones, another PC via ethernet) I can see all these servers and access them.
When I am connected via wi-fi directly to ADSL Router I cannot see any servers.
I read it should be a IGMP issue, but I cannot find any setting about it in my router configurations and I have understood that IGMP is enabled by default.
The two modules of the kit are connected correctly: I can go on the web and in the configuration page of the router I can see all my hosts.
The only thing that doesn't work is the DLNA and SMB protocols: it seems the powerline cannot share these protocols.
I have already open a ticket in the support page but till today no answer.

Do you have any idea?
