Noise level is the amount of interference in your wireless signal, so lower is better. For example, in my family's store our wireless is unusable due to the excess amount of noise in our connection caused by nearby business' wireless security cameras.

Noise level is the amount of background interference that occurs during data transmission. You want the "noise" level to be as low as possible for a better transmission of your data without interference.

Anytime you broadcast/transmit data, electromagnetic interference (EMI) is created, your goal is to minimize this to the greatest extent possible.

Google is my friend...

According to another forum... the following was stated:

Quote:
The negative numbers indicate a loss of power as the wireless wave travels. So what you want are signal/noise numbers closer to zero.


The stronger the signal, sans interference, the higher the data rate can be, to a point.

A good WiFi signal strength is -70dBm or more positive.
A poor WiFi signal strength is -90dBm or more negative.
More or less... -78dBm is "OK" I suppose, could be better... but it is what it is.
