What steps should a network engineer take to troubleshoot intermittent connectivity issues with wireless devices in a warehouse?

Performing a site survey is a crucial initial step in troubleshooting intermittent connectivity issues with wireless devices, especially in an environment like a warehouse where physical obstructions and interference can significantly impact wireless signals. A site survey involves analyzing the layout of the space, identifying sources of interference (such as machinery, metal shelving, or other electronic devices), and determining the optimal placement for access points to ensure robust and reliable wireless connectivity.

By conducting a site survey, the network engineer can gain insights into the current wireless coverage, signal strength, and quality of the connection across different areas within the warehouse. This data is essential for identifying dead zones or areas with weak signals where intermittent connectivity issues may be occurring. It allows the engineer to pinpoint specific problems related to the physical environment and take corrective actions, such as adjusting the placement of access points or increasing the number of devices to improve coverage.

The other options, while relevant in other contexts, do not directly address the immediate need for understanding and resolving connectivity issues. Creating a heat map is beneficial for visualizing coverage and signal strength but may not be as useful without first gathering data through a site survey. Installing a captive portal pertains more to user authentication rather than connectivity issues. Upgrading security protocols, while vital for securing the network,
