Thanks a lot for the help and the info!
Are PowerLine adaptors a decent alternative?
I’m hearing very conflicting reports.
What category of cable you use absolutely doesn’t matter for home use as even cat 5e will run 1 gbps, and that’s barely even sold anymore. Getting some kind of cat 7 shielded cable will just be annoying as it’s stiffer and more unwieldy. Just go for a standard unshielded cat 6.
It is if the power lines in your house/apartment are decent. I use it and the speed is faster then wifi. The advertised advantage is no dropped packets, I can say that my online experience is far better now that I moved to powerline for my PC.
I really wish the PS4 (or any console for that matter) supported 5ghz wifi. Both the N and AC standards would allow for you to play on wireless with no issues. On AC you wouldn’t be getting interference from other networks, microwaves won’t bring down your internet, your transfer speeds are in complete excess of what gaming would need for the next 10 years, packet loss is on par with gigabit ethernet, and the hardware runs cooler.
After experiencing the gross inaccuracies of their speed test I’m wary to trust anything from Ookla.
Honestly if you’re wireless, don’t even play online. Completely serious. You’re ruining the game for all the wired people
Also good to know:
DOWNLOAD & UPLOAD SPEEDS BARELY MATTER.
It’s PING what matters. Getting a 100mbps connection won’t give you good matches if your ping sucks. The packets that the game sends and receives are sooo tiny, that the speeds are irrelevant, and it becomes all about ping (which is just straight up delay)
Picture related. Thanks to Finnish god-tier fiber optic connections, it’s almost impossible to spot a difference between online & offline when playing with nearby players. I’ve got a ping of 12ms (1 frame is 16ms) to people over 200 kilometers away from me, and a ping of 5ms with people living in the same city.
Whenever you’re buying a new connection, ask around your ISPs what sort of cabling do they have, and if fiber is available.
If you can’t wire up to your router, use a powerline. I’ve been using one for the last year and it’s great. Definitely see an improvement in performance.
swedish internet !
I wish I was a Swedish Viking. 
From my own experience, in my old appartment, the connection speed with powerline was indeed better than with wifi but the pings were equivalent (about 20ms) and a lot higher than when I used a 100 ft ethernet cable (about 8 ms).
While it’s correct to say that you barely need any bandwidth to play online games, bandwidth does matter a lot in practice, especially in homes with more than 1 user. Any low bandwidth connection is going to degrade tremendously if a download or stream is running at the same time as Street Fighter.
So imagine my horror when I’m doing maintenance and disable the G support and then my kids 3DS’s stop working.
I get them the New 3DS XL. Surprise, still Wireless G.
Point to point between 2 3DS’s 2 feet apart will still experience disconnects.
I can get between one and two bars of 3G using my cellular hotspot. Will that work?
Just don’t use top spin on yourself.
I really wish the ps4 didn’t support wifi at all.
The primary benefit for a wired line is a lack of interference, but latency isn’t really distinct between the two, so provided your line is stable you shouldn’t observe much difference between the two.
I keep my console on wired for consistencies sake, but my 2nd and 3rd household PS4s stale on wireless. When I have buddies over to play games like Rainbow Six Siege, all three of the consoles ping the servers within 1 milisecond of one another, none of them exhibit noticeable lag or disconnections.
A big difference with wired versus wireless is the amount of bandwidth available across the two, but that’s not really a factor for online play, as this game won’t use more than 100kbs or so, at any one time. A relatively small amounts. Still, you can obviously create bottlenecks on your network if you’re streaming or torrenting etc. at the same time as playing the game.
Overall I would say just use whatevers ideal for you. Don’t rearrange your household for a wired line, and if you have to, just use wireless. If you can plug the cable in because you’re router is close by or easily moved, it’s worth it for consistencies sake, but I think the differences are often overstated.
I just bought some power plugs for this. I honestly don’t think it will make a difference.
Google fiber got it
