Please help, PS5 can't stream
I will preface this by saying I'm an electrician, I know the cables and how to hook up the devices but I'm not familiar with 90% of internet terms. I've found posts about this on reddit from a few years ago, tried everything, and still no luck.
I had ziply for years and had no issues, then I started losing internet connection for hours, sometimes days at a time for no reason. I could always connect to my router, which was wired to the ziply box, but it couldn't get internet. Customer support was no help at all.
Last week my wife brought home a tmobile internet package because she's an employee and got a good deal. We got a gateway and a mesh extender.
Since setting it up, internet speeds have been fine and we can stream Netflix and such without any issues, downloading games works fine and all that. I can stream Xbox games from my TV and remote play with the Xbox, though sometimes doing that gets pretty laggy and occasionally crashes.
The Playstation 5, however, is a different story. Streaming games is nearly impossible. Every time I try it tells me "Your connection quality might not be sufficient to play streaming games. Try using a wired LAN connection to improve connection speed and stability". Every single time. I got it to work once, and it worked phenomenally, I played Spider-Man 2 for about 4 hours without a single hiccup. Tried again a few days later, same message. So I crimped some RJ45s onto a piece of cat6 and made it a wired connection from the gateway to the Playstation. Same message, including telling me to try a LAN connection.
The mesh extender wasn't helping much so I unplugged it, and plugged my router into the gateway. I used the Hint control app to turn off the wifi from the gateway to attempt to make it a modem with no wifi, and use the router for all wireless connections. I've tried the Playstation with a LAN connection in this setup, both directly to the gateway and in a LAN port on the router, and wirelessly, same message each time.
On the Playstation, I changed my DNS settings to 8.8.8.8 and nothing changed, changed my MTU settings. It's been Type 2 NAT the entire time. I've spent nearly 30 hours messing with it and trying everything I see on the forums, some things from a few years ago and some a few months old.
The T Life App is nearly useless, it has no relevant settings that I can change to like some of the forums said, not sure if they got rid of that option with new models or if I'm doing wrong. I can't find any DHCP settings for tmobile, nor CGNAT settings.
My connection speeds aren't bad, every test I do is nearly 200Mbps or more sometimes, which isn't much worse than it was when I could stream on ziply.
I'm at a loss and ready to return this potential POS, but I I see other people have found workarounds in the past and after streaming the game for so long without issue I KNOW that it's possible, I just don't have the proper knowledge or context to figure out how. Not sure why the Xbox seems to hobble along but the Playstation simply refuses to try.
I'd love to save the money vs ziply with my wife's discount, and it's certainly easier to use, but streaming games has been my solution to constantly deleting and downloading games to make the small ps5 hard drive usable, and if I can't do that then it's not worth the relatively small amount of money saved.
Any tips or solutions would be greatly appreciated, but keep in mind I may not understand, so please phrase it as you would to someone who has basically never been this involved in their ISP and router settings, because that's where I'm at. Thank you in advance.
