I'll start by saying that I do not have an IT background or much knowledge on the subject, so I apologize if I am not using the proper terminology or have a tough time understanding what is being said.
I purchased a TL-SG105 switch and wanted to use it so that I can hard wire in multiple devices (smart TV and cable box). Currently, the Ethernet cable from the wall jack goes straight to my cable box only. My smart TV is connected via WiFi, but I want to hardwire it because the WiFi signal can be spotty at times.
I plugged in my new switch and then plugged the Ethernet cable from the wall jack straight in to port 1 on the switch. I then ran an Ethernet cable from port 2 directly to my cable box and then ran another Ethernet cable from port 3 to my smart TV. My smart TV wired connection ran just fine... no noticeable issues with internet connectivity or slow speeds when streaming. My issue was with the cable box. If I turned the cable box on and went to a channel, it would work for maybe 5 seconds and then freeze up and stop working. I tried it a few times and the same thing happened each time. Since the switch and everything worked just fine with my smart TV, I am thinking the issue may lie with my router settings or something else in relation to the cable box?
My router is a Zyxel EMG3415-B10A. It was provided by my cable/internet provider. I know how to access my router settings from my computer, but that is as far as I know how to do. I really do not understand anything within the settings themselves. I can see a list of connected devices and have the option to "add device into static DHCP" but I have no clue what that means. Other than that, there are a lot of other settings I can adjust but I am unfamiliar with what they do.
Any advice or things to try out would be very much appreciated! I am afraid of messing up something within the settings and then not knowing how to fix it, so I thought I would ask here first. Also, since my switch is the "unmanaged" version, I do not believe there are any settings I can adjust with that?
Thank you for your help!
