Section 2 - Installation
Assessing Uplink Signal Strength
The Status/WPS LED will turn solid green when the DAP-1620 has connected successfully to a wireless network and is extending
that network. If the Signal Indicator LED has a single amber bar after the connection process has finished, the DAP-1620 has
established a poor quality connection. The more lit bars on the Signal Indicator LED, the better the wireless signal. To improve the
connection quality, the DAP-1620 should be relocated closer to the source wireless router. Using the 5 GHz extension network is
recommended in order to achieve the fastest wireless speeds.
