The computer I was referring to is the server I am trying to access. I've accessed the webpage from my laptop.
There is a strange thing indeed: the server has actually no firewall, however the 1900 UDP port, which should be open for SSDP seems closed.
Here it is the result of some investigation --- # On my laptop $ nmap -sU -p 1900 santini_server Starting Nmap 7.40 ( https://nmap.org ) at 2017-06-05 11:32 ora legale Europa occidentale Nmap scan report for santini_server (192.168.0.109) Host is up (0.027s latency).

"systemctl status minindlna" showed that it wasn't able to identify the network interface i provided. i have no idea why(old method in minidlna?). i commented that line in config back out and made sure minidlna could read my testing media directory and it worked at that point. i used nmap -sS -sU -T4 -A -v 192.168.1.1 to see if port 8200 was open. it was.
so, if "systemctl status minidlna" or "journalctl -b" shows no problems for minidlna then maybe test with nmap from both wired and wireless and see if there is a difference. If there is, then you have network config issue. the arch wiki page for minidlna has a section about wireless in the troubleshooting section i notice.
