I upgraded my internet here where I live, and Im setting up the wifi. When i run the speedtest on my iMac, it shows up at around 95up, but when I run it on my iphone X, the speeds are in the 50s. I figured maybe I would disconnect and reconnect to the network on my X, but when I forget network on my X, it also forgets it on my iMac and Macbook. When I connect everything back up, my Macbook (which is in the living room near the router) runs at around 95, my iMac (in the bedroom) runs a little slower since its a room/distance away, and the iphone runs around the same as the macbook. Then after a few minutes, the macbook stays the same, while the iPhone and iMac are around 40-50mbs slower.

Anyone have any thoughts?

Sounds as if your router is screwing up!

Im right next to my Macbook. At the moment, its running at 90mbs, with a 12 ping. I run a test on my iPhone, Im getting 30mbs less, with a 200 ping. I have reset all my network settings, and even reset my phone, and its still doing it.
 
Might check noise on the Wifi channel(s) for noise and other devices/networks, or try other channels.

Is everything connecting 2.4GHz, or 5....or a combination?

Is your router/firewall doing anything else that might effect throughput, like content filtering?

How are you testing the connection speed? Any chance the tool is not accurate/inconsistent?
 
Since Speed Test measures 2 things - your internal network speed, as well as the speed at which your (cable modem?) connects to the internet, it is sometimes helpful to just look at your internal network speed.

One way to do this is to install "Network Speed Tester", available on the app store. There are two programs: server and client. You install the server on your iMac, and the client on your iPhone X. Here's a result that I got running the client on my iPhone X:

As you can see there is quite a variation, almost 150 mbps ...

Then what are your wireless frequencies are you using b, g, or AC? How many wireless devices using your wireless or if any other wireless is in your area (like dorm, apartment, condo)?
 
I was connected to 5 GHz AC Time capsule. The iPhone X was only a couple of feet away from the Time Capsule. No other devices were being used since I wanted to determine the maximum bitrate possible for the device.

For a more realistic test I then went upstairs, a distance I'd guestimate ~ 30-40 feet and got

I was streaming Youtube video to the Apple TV while running parts of this test, but the video bit rate was very low, ~200kbps.

I don't have long distances to worry about so the Time Capsule meets my needs quite nicely right now.

Im in an apartment. I have my iMac in my bedroom, running around 80-85mbs. My Macbook is in the living room, and that runs around 90mbs. My Samsung TV is wirelessly connected to the router, and my PS4 is wired to it. The only other thing connected to the router is my HP printer.

Now, here is what is interesting...when I am out, my latency on my iPhone is around 15, but when I am home, on my network, its over 200. I only see these issues when I am home. And when I run a test, it will start high, like in the 60s, then slowly drop to the 40s.
