ISP blocking

Im sure its been asked before but i can’t seem to find anything on here or via google.
My ISP block all content that i want to stream through my ATV, a way round this was to tether through my phone. My tethering allowance has now been cut so i need to work how to use my internet on my ATV once again.
Im sure there are ways round this i just can’t find them. Could someone point me in the right direction please.

How does your ISP manage to block anything on your home network? AFAIK that just isn’t possible. If your ATV isn’t streaming, I doubt its the fault of the ISP, you should check your internal network settings instead.
