2018 MBP slow network speeds

[AFPoster]

In December I spilt orange juice on my keyboard at Starbucks. I took it to Apple and they cleaned it at the store over 3 days. Upon return, my battery wouldn't last more than 3 hours, so I took it back and they replaced everything in the lower casing.

Now that I have it back, 55mbps is the max I can get on the network and the screen freezes several times a day. My iMac, iPad Pro and iPhone XS can all hit 150+ without an issue. On average, the MBP gets 7-12mpbs, again, 55mbps being the max.

Logic board or should I try something? I've reinstalled the OS 3x, no change.

Try doing Ping
Ping Google to see what speed you get.
In Spotlight type Network Utility
Use Ping Tab and type Google.com (10 pings)

Take it back as they likely damaged the antenna wires and something else as the screen freezes. Did you live with this for all of last month? Because they might warranty their work if it has been a while since they fixed it.

I'm still under AppleCare, either way it's covered thankfully. I just can't keep losing my laptop for 1-2 weeks at a time.

It's -56dBm

Ping is good and signal strength is strong. Since you seem adamant that the max speed is limited, it ought to be pretty easy to demonstrate that to Apple. Let them take a look.

Yeah, OPcan run a Speedtest at the Apple store on their network

Thank you for reporting
The Good News
1- Your signal strength (RSSI) is excellent
2- Your connection speed is good (Ping)

Lets try few simple settings
1- In Syst Pref > Network change the "Location" (create new one and name it) add your WiFi > Apply and TEST
2- In Syst Pref > Network > Advanced > Hardware > set Configure: Automatically (MTU 1500) is data package size)
