To check how your WiFi performs, you should open your terminal and paste the following:
/System/Library/PrivateFrameworks/Apple*.framework/Versions/Current/Resources/airport -I
This will print out a screen similar to this one:
agrCtlRSSI: -54
agrExtRSSI: 0
agrCtlNoise: -97
agrExtNoise: 0
state: running
op mode: station
lastTxRate: 144
maxRate: 144
lastAssocStatus: 0
802.11 auth: open
link auth: wpa2-psk
BSSID: f9:77:99:2d:3d:60
SSID: name
MCS: 0
channel: 11
You want agrCtlRSSI to be as low as possible (up to - 55 things are great) and agrCtlNoise to be as high as possible (-120 is the max).
I've had a lot of issues with figuring out the strength of different WiFi connections in my coworking space, and this did the trick. I hope this helped you discover which WiFi network is performing the best for you!
