Stuttering with online play only

[Toxitaes]

So a week or two ago I started noticing a very bad stutter while playing online (csgo and Rocket League)

System specs:
cpu: fx6300
ram: 8gbs 1600mhz
gpu: r9 380 4gb
I'm also using a wireless connection

Process:
I tested out Firestrike and The Witcher 3, and both ran as they normally would.
Therefore I figured it was either my internet or some type of software limitation.
I then tested out another computer with Rocket League, and it ran flawlessly. (also on a wireless connection)
I then switched the wireless adapters around, but my computer still stuttered.

At this point I know something with the software must be off, and I don't really know where to start. I don't remember downloading anything immediately before this started.
Thanks

Ethernet. Solves all of my internet problems. I had the same problem a couple months back and wired internet works.

No that's not the issue. My other computer runs wireless with no problems, and when I tried switching around the adapters the stuttering was still the same. I live in a more rural city so there would be very few interruptions to the signal.
