I have at my home a download of about 50mbit / s and an upload of about 10Mbit / s.
When I do a test on the Ps4, the upload always stays in the range of about 2.5Mbit / s. Download remains about the same.
When I do a test on the PC, everything is as it should.
Why is that? Had on the Ps4 like my full 10Mbit / s in the upload.
Is also no display error!
Maybe this helps:
For the "IP address settings" go to "Automatic" and go to "DNS settings" to "Manual". Use addresses 8.8.8.8 as "Primary DNS" and 8.8.4.4 as "Secondary DNS".
