Issue

The wifi connection to my PS4 always results in very low bandwidth speed no matter what I do.

Brief Description

Having Charter internet, I was getting a rated speed of 60Mbps. My wireless router, an ASUS RT-N56U, is located on the first floor of my house. Any device connected to it, at the same level, would get an average of 45 Mbps.

The speed dips down on the second level to ~30 Mbps. I do own an xbox 360, located farthest from the router, and gets 25 Mbps. It does have a network adapter which could help boost the speed. The issue, however, comes in to the PS4 that is located on the second story directly above the wireless router that gets ~10 Mbps download speed.

Attempts

I have attempted the following steps:

  1. Forward ports listed
  2. Move PS4 downstairs
  3. Connect PS4 through cable from wireless router (45 Mbps)
  4. Connect PS4 through cable from cable modem (55 Mbps)

I contacted my ISP, found out that I can get a data increase to 100Mbps. This boosted my other devices to ~50 Mbps on the second level, but did nothing to the PS4.

Additional Information

I have two PS4s, the problem with both, except one is connected through LAN. Wifi connection to PS4 (after restarting modem and router) starts at ~70 Mbps, then levels off to ~10 Mbps even after limit increase.

Question

Is the problem with PS4? Or communication between PS4 and router?


Update

As suggested in the comments, I tried turning the router on its side without improvement. I purchased a Netgear R7000 and tested it. LAN connection to PS4 improved to 100 Mbps (instead of 80) and wifi went from ~10Mbps to ~45 in upstairs PS4.

    This feels off topic here. Especially as the problem is specific to the PS4, other devices seem fine. As long as the focus is based on the network then this is okay, but the ps4 is not a "computer" within the context of our site scope. – Mokubai Oct 16 '17 at 15:47
  • Also signal can vary a great deal depending on antenna alignment of both devices. Having a horizontal alignment of an antenna (antenna "stick" is vertical) can easily create a signal "void" above the router. – Mokubai Oct 16 '17 at 15:51
  • @Mokubai, I wasn't sure what other site would do. I am trying to pinpoint the problem to determine if it's a networking or a PS4 issue. As for the antenna alignment, even when the PS4 is moved from above router to same level as the router, the bandwidth remains the same ~10Mbps. – Leb Oct 16 '17 at 16:16
  • If it is a PS4 issue, I would expect it to happen to one of them, not both. If it is a networking issue, why does it happen to the PS4 only? – Leb Oct 16 '17 at 16:17

    It could easily be that the PS4 design results in a particularly badly aligned antenna for your situation. Other devices may be more omni-directional and result in slightly better reception. Try putting your router on its side or put your PS4s on their edge stand rather than their larger base. – Mokubai Oct 16 '17 at 16:37

Sounds like it's either a firmware issue or a PSN issue. More likely PSN as I have similar issues with mine on a Cisco C2960G switch and a PFSense router tested to 900Mbps throughput tied to a 40mbps connection.
