Stream to tablet?

I can do it over wi-fi with samba or DLNA but I'm wondering if doing it via hotspot will consume data. I doubt it but I'm not sure. With the Inspire I could turn off mobile internet and still use hotspot, with the sgs4 I must connect to the Internet to use the hotspot.

[Q] Please help with mobile hotspot

My problem is that my Lenovo A3000-H does not allow devices to access 2g internet neither through WiFi hotspot or USB modem. 2g internet works on its own, I can connect to WiFi hotspot and ping the Tab, however there is no internet no matter witch device I am using. Interesting thing is that if I connect A3000-H to the internet via WiFi and then connect it to my laptop via USB and use it as modem, my laptop has internet, but as soon as I disconnect WiFi on the Pad, 2g kicks in, but internet connection on my laptop dies.
Any help will be much appreciated.

How to connect to a WiFi network, but use mobile data for Internet access.

I'm using a little DLNA box (with no internet access) to connect to my audio system.
My rooted phone connects to the little DLNA box via WiFi. However in doing so, all internet access is routed to the WiFi connection and therefore I end up with no Internet access.
My phone does have a working 3G/4G/LTE connection through a SIM card, though. IKs it possible to stay connected to the WiFi purely for DLNA purposes and use internet through the mobile data connection?

Use LTE when Wi-Fi network with no internet connected.

Hi all.
I need my android tablet to be connected to the wifi network with no internet. The tablet uses some app and gets data from that wifi network.
The issue is that I want to have internet too for web surfing and streaming music. But android doesn't allow to have LTE internet when wifi is connected.
Android 10, RockChip PX5.
Please, help with a solution if you know.
Thanks.
