Coax cable problem

[opokucarine]

I have only one coax input on my wall and I need to it to connect to the WiFi and tv. Is there anyway the TV or modem can work without coax cable so o can connect it to only one

No.

You should have a cable coming in, and that should then split. One to the modem/router and one to your TV/Set top box.

In some cases the device you are working with will have an in/out, so you can come in from the wall and then out to the other appliance. Otherwise, go to your local hardware store and get a splitter and a couple of small cables if you don't already have them.
