Hi, I currently am running a Fiber modem/router combo outside my house. Unfortunately, it is not in a great spot to provide proper WiFi signal to the rest of the building. I then have a WiFi router connected to one of the Ethernet connectors in my house to create a WiFi signal and network my 2 computers. Now here is where I am running into problems. In my living room I am connecting a wired chomecast ultra, sound bar with built in chromecast, TV among other things with a 8 port switch. I can't seem to get everything to see each other and communicate one one network. Any suggested changes to either router settings? Thanks in advance for the help.
