PlayStation 4 set-up with AT&T Fiber and BGW210-700
I recently got the AT&T 300 mbps Fiber plan, along with the Arris BGW210-700 modem/router that is provided with it. I have connected my PlayStation 4 (PS4) via LAN to it and it is able to go online and play multiplayer, with a NAT 2. However, my Download and Upload speeds on the PS4 are very low to my laptop or other devices. Despite my 300 mbps plan, my DL speeds tend to be low 100's and my upload is terrible, only 1-3 mbps. I cannot host or use SharePlay at those speeds.
I've tried opening ports via the NAT/Gaming option via my network gateway, but nothing has changed. Please advise.
