I've tried that before and my PS4 still downloads at about 1/3 the speed my laptop does (being very generous). Sony is just being awful with this issue.I don't remember this being a problem at launch...
In fact its being terrible right now. Trying to download the black ops 3 beta and it went at the right speed for a few seconds and said 33 minutes left, then it slowed down and said 19 hours left and hasn't sped up again at all.
really mtu in most cases should be 1472 NOT 1473
ping -f -l 1472 www.dslreports.com
and change the number to see what your max mtu is for your ISP... there are other ways to check, but thats what I did (Command Prompt)
also I had to keep pausing and resuming as well when it got slow... weird thing is changing mtu and dns to 18.104.22.168 and 22.214.171.124 actually made my connection test slower, but improved my download speed load[/code]
