Original PS4, Hub 3 M350 package, wired connection.
Recently noticed what I thought was lagging, nobody else in my team had any issues. Gradually getting worse to point that games were completely unplayable, and even scrolling through PS4 menus was troublesome. Have stripped and hoovered the PS4, have reflashed the HDD, have loaded games on to an external HDD and nothing made any difference. PS4 generally downloads 40MBps+ and uploads 8-10Mbps.
The last two evenings I've loaded up and struggled, then flicked the ON OFF on back of the router, waited 5-10 mins for lights to come on and go out and then had hassle free gaming for many glorious hours.
I understand a router issue causing game issues but not scrolling through PS4 menus yet the on off seems to have resolved it with ease.
Any thoughts please before things start getting thrown around. Thanks in advance
