Greetings

OS: Windows 10 Pro

modem: sagemcom cable modem

Where do I find instructions for configuration of tp-link td-w9970?

specifically I'm intertested in firewall and forwarding

2nd question: since the router supports WMM and UPnP why can't I see all wi-fi devices in my home?

I can see the printers, phones, tablet, TV

I fail to see streamer (dune) and receiver (marantz)

found IP address of streamer but I can't see it in control panel --> network

please help

thank you
