Datto Networking App: Site Survey
Topic
This article describes the Datto Networking App's Site Survey option.
Environment
Description
The Site Survey tool is a reference to gauge network congestion caused by surrounding access points broadcasting on the same channel. A signal strength of 70% or higher could indicate a source of interference. If you see slow wireless speeds:
- Change the channel over which the radio is broadcasting (Datto suggests channels 1,6, and 11).
- Use the Auto setting to have the access point choose the best channel to use.
The site survey may also reveal rogue access points, which are unauthorized access points deployed within your local network. Use this tool to identify and remove these unknown or potentially malicious access points.
Running a scan
In the Datto Networking App, click Site Survey, then click the Scan Now button. The site survey scan takes up to 30 seconds, during which any SSIDs on the access point will not be available.
