Slow download & upload on PS5 using 1000/1000 AT&T Fiber

Can you do a speedtest with some other device (phone, computer) to determine if this is just a PS5 issue?

I came across a site that talks about a hidden browser in the PS5 and to use that to run a speed test which will bypass Sony's.  https://nerdburglars.net/hardwareguides/fix-slow-upload-speed-on-ps5/

It also talks about changing the DNS on the console.  We had another PlayStation user in here awhile back and he said changing it to 1.1.1.1 brought his speed back to normal.  I questioned the "how" part of that since DNS servers shouldn't have any affect on throughput but he tried different DNS servers and was able to reproduce the slow speeds.  They went away when he went back to the Cloudflare 1.1.1.1 server.  🤔

My understanding is that sometimes the AT&T DNS servers have IP's that are "optimized for their networks."  When you think about things like Netflix Open Connect content servers, that makes a lot of sense.  I don't know why Sony would have different IPs, or ask AT&T to use them, but I could see that it would happen.

So you're saying if you use a certain DNS provider that they may return a different IP address for a specific query, one that would result in a different, faster route?

I think the previous post also tried Google's 8.8.8.8 and had poor results as well.

Yes, I'm saying that originally, all DNS servers were really supposed to go to an authoritative source which should really have one number, or a rotation of numbers they'd give everyone.  But reality has diverged from the original operating model (just like open SMTP, randomized MAC addresses, HTTP without SSL/TLS, etc.)

The IPv4 is just a load balancing rotation of 3 addresses.  The IPv6 addresses are different.

Just got 1G fiber installed last week w/BGW320-500 and I am having the same down/upload speed. Did you happen to figure it out? I saw a guy on Youtube that has the same 1G and is getting 900/200. Idk. 

Were you able to bring up your speeds? I got AT&T fiber and have only been getting in the high 400s for download and low 100s for upload 

I subscribed to 1G fiber about two weeks ago. I configured my BGW320-500 for IP passthrough since I manage my network with a ASUS AX86U router. When I run a speedtest from my computer with a hard connection to the router the best I get is around 570 down and 530 up. When I log directly into the BGW320-500 and run its internal speedtest to the internet it says both down and up is 900 or more. It appears that the BGW is somehow slowing speeds in both directions. My question is- Are there other options besides the BGW if I just want passthrough?

I’m having the same problem. I’m getting about 450 down and like 20 up on my PS5. I was currently getting at least  860mbps with a Xfinity and my cable modem. I just switched to AT&T because I moved to Texas and got the one gig up and down. I’m getting it on my laptop at 1.1 gigs down at 600 up. But for some reason, I can’t reach it with a PS5 is there anything I can do?

You did not say how the PS5 is connected, but the highest bandwidth will be with an ethernet hard line. Even then you need to make sure any ethernet switches and/or routers between the ATT gateway can and your computer/console handle 1G. Having said that, testing on my local network gets me 760 Mbps down and 700 up. On the network side the gateway measures 999 Mbps down and 929 Mbps up.
