Network Switch not working for some devices

[eprpalmeida]

Hi guys, recently I´ve bought a network switch (D-link DES-1016A https://www.amazon.com/D-Link-16-Port-Gigabit-Switch-DGS-1016A/dp/B0092KZBCQ) to my house. I connected an ethernet cable end on my ZTE modem and the other one on the switch. The first cable that I tried was the Ethernet cable of my PC. It worked without any issues. I connected the cable of my Smart TV to the switch and then, didn´t work. I unplugged it and connected to the modem directly, and worked. I noticed other devices that worked with the switch (my laptop and my PC) and devices that didn´t work (smart TV and 2 access points). These devices that didn´t work with the switch works flawless when connected directly to the modem.

I tried changing cables but it is not the problem. What could be causing this issue?

You can't have a switch directly after a modem. You have to have modem -> router -> switch. If your ZTE device is really just a modem, then only one device can get an IP address.

Sorry, forgot to specify, it is a modem and a router, on the same device.

OK, if that is the case, my guess would be the "Green Ethernet" feature of that switch causing problems.

I have the switch connected between the modem and the router, the router gets internet but other devices via switch don't, devices do get internet via modem - switch - router, only the router is able to communicate with the switch, so you saying that switch would communicate with other devices if it's on other side of router?

Your ISP only provides one IP address. The router gets that IP address. That is why nothing else works. You have to have your router as the first device after the modem.
