ssh, telnet, upnp on Archer C2 router
Hi
I have an Archer C2 750 router. I ran nmap 192.168.0.1 from my computer and it reported that these are available :
22/tcp open ssh
23/tcp open telnet
80/tcp open http
1900/tcp open upnp
I wasn't able to ssh into it, the following link states that its for use with an app only, no login. is that correct?

Can I shutdown or limit telnet? I was able to limit login over http to one computer on the local network, didn't affect telnet which was still accessable by others.
What is upnp for? I switched off upnp via admin webpage and nmap reports service ir running (or port is open anyway)
Thanks,
Rob
