I can’t seem to reply to this thread so I’m starting a new one:
Any update to this issue, I’m having this problem at the moment.
I have a DLNA Media Server (NAS) connected directly to my primary router, any device connected to my WD N9000 (in AP Mode) cannot see the DLNA Server however it can see it as a network share.
The second AP is needed to extend poor signal coverage, I am using the WD to replace a Netgear router which was also in AP mode however the Netgear worked without issue.
