Just did that, no luck.
I have confirmed it is the ISP though. I started using my verizon 4g hotspot and it's downloading flawlessly. Yes I'm burning through loads of data but my ISP wont help me
Heres our conversation...
Me- "Something on your end is blocking an update on my PS4. I confirmed it's ISP related by using my mobile hotspot and it works flawlessly.
Frontier- "We cant help you fix your playstation, contact PSN"
Me- "Its not PSN, its on your end somehow. Explain to me how it works using a different internet connection"
Frontier- Are you have any other issues with frontier services?
Me- No
Frontier- are you having issues accessing other websites?
Me- No
Frontier- Nothing we can do, contact PSN for support. Have a nice day

I AM FREAKING PISSED BUT THIS IS MY ONLY INTERNET OPTION!!!
