What is the optimum signal strength dBm for best performance?

On the status or overview page there is a signal strength meter which displays signal strength in dBm. The optimum is between -40 and -60 dBm. This is the range where you will see peak performance. At -80 to -90dBm the units will have a difficult time maintaining a reliable connection.

If the signal level is showing -30 you should turn the transmit power down a little in the wireless settings. If the signal level is too strong, it saturates the receiver and causes packet retries resulting in poor performance.

If you think the signal strength is too strong, we recommend starting by reducing the transmit power on both units by 1/2 and checking performance again. We don’t recommend reducing the power below 1/2 strength because signal to noise ratio will be reduced and may cause reduced performance.
