Hello,
The university I attend provides my room with one Cat 6E port in the wall for internet, the Wi-Fi is terrible and ethernet is much faster so I elected to go that route. I bought a small unmanaged ethernet hub (5 ports) Link Here. I used a Cat 6 cable to go into the link/act port on the hub from the wall port, then plugged my PC via Cat 6 cable to the hub and my smart TV via cat 6 to the hub as well. Everything was functioning great. However, I now wanted to hook up my PS4 via ethernet so I plugged in another cable to the hub to add the PS4 to my setup and then the green light coming from the link/act port indicating a connection from the wall stopped and I had no internet on any of my devices. I figured it was an issue with the hub so I plugged PC, TV, PS4 directly into the wall individually and none of them detected even an ethernet cable being plugged in meaning that there was no ethernet coming through the wall port. Today, I tried the individual connections again and they worked, so I again decided to try with the hub and test where the problem lied, again I plugged all devices in one by one as described above, all lights and internet was good until I plugged in the third outgoing cable (PS4) then I lost all internet again and the port no longer works now. Did I short something out, did I overload something. Any help would be appreciated!
Yes a router could mask the fact that you’re sharing devices, but that could be against the university’s rules. especially if you turn on Wi-Fi.
