Clients with Low SNR Minutes

The Clients had experienced unusual high number of Low SNR minutes insight can be accessed from the Global, Site, Access Points, and Clients context. This insight provides information about access points that have a low-quality signal-strength connection and is categorized under wireless quality as the clients connecting at a Low SNR Signal-to-Noise Ratio. SNR is used for comparing the level of a desired signal with the level of background noise. have low throughput and high retransmissions. This insight displays the following information:

Insight Summary

The insight summary provides the following details:

  • Reason—Displays the possible causes for which the APs experience low-quality SNR connection in the network.
  • Recommendation—Displays the possible recommendation against each failure to resolve the same.

Time Series Graph

The time series graph displays the number of clients with low SNR uplink AP during the selected time period. You can hover your mouse on each bar graph to see the number of SNR links.
