Streaming with my 4G connection via AllConnect App.

My TV is hardwired via LAN to my router and my phone is connected to same router via WiFi. I am able to stream from my Phone to TV when my router has internet connectivity. But I want to use internet connectivity of my 4G LTE phone, so I connect with cellular data and am able to play on my phone but as soon as I want to stream via AllConnect App it does not see the WiFi. I switch ON/OFF the WiFi it connects to TV but can't play it. So basically when my router has internet connectivity my phone streams to TV but when my router doesn't has internet connectivity my phone doesn't stream to TV. I want to use my Phones 4G LTE data connection to stream from my phone to my TV via my router and use my routers WiFi to connect my phone to TV via DLNA. I don't want to use my routers internet for that I disconnect the DSL cable. So I have an active WiFi connection for my my phone to connect to TV but no internet connectivity.
TV = Sony Bravia KDL 40EX520
Phone = Haier LS-5014 and OnePlus One A0001
Android Ver = 6.x
Router = Asus DSL N10E
Streaming App = AllConnect Ver 8.2

I hook up my TV with LAN (Old Sony Bravia) to my router and my phone to same routers WiFi. So I am able to share and connect with TV. I am also able to cast Movie HD app on my TV using the AllCast app, No issues. I have a crappy wired internet connected to it. I also have unlimited 4G plan on my phone. I use AllConnect to cast from my Phone to TV. Now I am able to cast Movie HD app via AllConnect on my TV. But as soon as I disconnect the wired internet from my router. I am not able to cast. I want to use my Phones 4G internet to stream on my TV. Theoretically it should be possible to cast using my routers LAN which I am able to. But as soon as I disconnect DSL cable from my router the streaming stops. Can anyone help me here.
