Datto Networking: What is the Site Survey tool?



This article highlights the Site Survey tool that is included in the Datto Access Point feature set.


  • Datto Access Points


The Site Survey tool is meant to serve as a quick-glance reference for the wireless environment surrounding your Datto network. When running a Site Survey scan, the access point will stop serving clients and will scan for non-Datto radios in the vicinity.

The Site Survey scan takes up to 30 seconds, during which any SSIDs on the access point will not be available.

Scan Frequency

The scan will run as part of the boot cycle for the access points. To manually initiate a scan:

1. Navigate to a device web session for your access point.

2. Click the Manage dropdown, followed by the Site Survey link.

3. Click the Scan Now button.

If the Auto option is selected for the radio's channel setting under Configure > Radio, the Site-Survey scan will also run during the access point's maintenance mode window to select the best channel to broadcast under in your environment.

Reading the Results

  1. Signal: Radio signal strength represented as a percentage.
  2. Channel: Which 2.4/5GHz center channel is being broadcast.
  3. SSID: What SSID name the radio is broadcasting.
  4. BSSID: MAC Address of the broadcasting wireless interface.
  5. Mode: What 802.11 Standard that is being used (b/g/n/ac).
  6. Encryption: Which WiFi security standard being used.
  7. Vendor: This uses the Organizationally Unique Identifier (OUI) of the BSSID to lookup the radio's manufacturer.
  8. Strongest Signal Seen By: Which Datto access point can receive this signal the most.
  9. Last Scan: Timestamp of when the data was collected.
  10. Scan Now: Clicking this will manually initiate a Site Survey scan.

Using the Site Survey

The Site Survey tool can be a good 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 potential source of interference. Changing the channel the radio is broadcasting under, or using the Auto setting to have the access point choose the best channel to use, can potentially resolve slow wireless speeds. Good channels to change to are 1, 6, and 11.

The results may also reveal Rogue Access Points, which are unauthorized access points deployed within your local network. Use the Site Survey to identify and remove these unknown or potentially malicious access points.
