I have been with AT&T for 5 months now. My PS4 share play functionality does not work anymore when it used to. The last time my PS4 share play worked was August 1, 2017. After that it has not work since then. I've called AT&T several times and even had tech come out to see what the issue is. I've done all trouble shooting options. DMZ, Ethernet cable, Hard reset / Factory reset. TCP/UDP port opening.I have the 1 gigabit internet plan.

It know for fact its something on AT&T end because I can use my Verizon hot spot from my phone to use my PS4 share play function. My thoughts are AT&T should not be doing automatic updates on our modems. I've asked if I can use my own modem rather then the one they provide and that is a no. I honestly feel like I am paying to be a beta tester for their modems because they don't know whats going on with the modem firmware to cause this problem.

Does anyone have any other solutions?
