Signal strength allows you to check how strong or weak the signal is.
STEP 2. Tap Status.

STEP 4. Check the Signal strength.
In the below image the signal strength is shown as a measurement in dBm. However the numbers will be shown as negative values.
So (-61) dBm will be a stronger signal than for example (-93) dBm.
dBm is an abbreviation for the power ratio in decibels (dB) of the measured power referenced to one milliwatt (mW).
